Household Power Saver
Household Power Saver - Efficent? What is the real truth?

A household power low voltage saving devices has recently received a lot of attention from both consumers and manufacturers. It is generally used in residential homes to save energy and to reduce electricity bills. It is a small device which is to be plugged in any of the AC sockets in the house (Mostly near Energy Meter). Moreover, some of the companies claim that their power savers save up to 40% of the energy.

Many people believe that the claims made by the power savers manufacturing companies are false. Almost all people who buy power savers do it to reduce their electricity bills.

Many people who have used these power savers said that they could reduce their electricity bills with the devices; however the reduction was not as much as they had expected. Moreover, they could not figure out if the reduction in electricity bills was due to the power savers or because of their efforts to reduce their electrical usage. There have been several serious discussions about the genuineness of the device.

In this note, we will try to find the real truth behind these power savers which claim to save as much as 40% of energy.

Working Principle of Power Saver as per Manufacture

A Power Saver is a device which plugs in to power socket. Apparently just by keeping the device connected it will immediately reduce your power consumption. Typical claims are savings between 25% and 40%.

It is known that the electricity that comes to our homes is not stable in nature. There are many fluctuations, raise and falls, and surges/Spikes in this current. This unstable current cannot be used by any of the household appliances. Moreover, the fluctuating current wastes the electric current from the circuit by converting electrical energy into heat energy.

This heat energy not only gets wasted to the atmosphere, but also harms the appliances and wiring circuit.

Power Saver stores the electricity inside of it using a system of capacitors and they release it in a smoother way to normal without the spikes. The systems also automatically remove carbon from the circuit which also encourages a smoother electrical flow. This means that we will have less power spikes. More of the electricity flowing around circuit can be used to power appliances than before.

Basically it is claimed that Power savers work on the principle of surge protection technology. Power savers work on straightening this unstable electric current to provide a smooth and constant output. The fluctuation in voltage is unpredictable and cannot be controlled. However, the power savers utilize current fluctuation to provide a usable power by acting like a filter and allowing only smooth current to pass through the circuit. Power savers use capacitors for this purpose. When there is a surge of current in the circuit, the capacitor of the power saver stores the excess current and releases it when there is a sudden drop. Thus only smooth output current comes out of the device.

Moreover, a power saver also removes any type of carbon in the system, which facilitates further smoother flow. The main advantage of power savers is not that they provide a backup system in times of low current, but that it protects the household appliances. It is known that a sudden rise in the power can destroy the electrical appliance. Thus, the power saver not only protects the appliance but also increases its life. Moreover, they also reduce the energy consumption and thus the electricity bills.

The amount of power saved by a power saver depends on the number of appliances on the electrical circuit. Also, the system takes at least a week to adapt itself fully to the circuit, before it starts showing its peak performance. The maximum amount of voltage savings will be seen in areas where in the current fluctuation is the highest.

Household Power Saver Scam Review

Power Factor Correction for residential customers (home owners) is a scam? At most, each unit is worth as an investment. Power factor correction does make sense for some commercial / industrial customers.

Many companies are promoting and advertise that their Power Saver unit are able to save domestic residential power consumption by employing an “active power factor correction” method on the supply line. The concept seems pretty impressive as the concept is true and legally accepted. But practically, we will find that it’s not feasible.

To support above statement first we need to understand three terms:

  1. Type of electrical load of house,
  2. Basic power terminology (KW, KVA, KVAR).
  3. Electrical tariff method of electricity company for household consumer and industrial consumer.

There are basically two kinds of load that exists in every house: one that is resistive like incandescent lamps, heaters etc. and the other that’s capacitive or inductive like ACs, refrigerators, computers, etc.

The power factor of a Resistive Load like toaster or ordinary incandescent light bulb is 1 (one). Devices with coils or capacitors (like pumps, fans and florescent light bulb ballasts)-Reactive Load have power factors less than one. When the power factor is less than 1, the current and voltage are out of phase. This is due to energy being stored and released into inductors (motor coil) or capacitors on every AC cycle (usually 50 or 60 times per second).

There are three terms need to be understand when dealing with alternating (AC) power.

  1. First Term is kilowatt (kW) and it represents Real power. Real power can perform work. Utility meters on the side of House measure this quantity (Real Power) and Power Company charge for it.
  2. The second term is reactive power, measured in KVAR. Unlike kW, it cannot perform work. Residential customers do not pay for KVAR, and utility meters on houses do not record it too.
  3. The third term is apparent power, referred to as KVA. By use of multi meters we can measure current and voltage and then multiply the readings together we get apparent power in VA.
Power triangle
Power triangle

Power Factor = Real Power (Watts) / Apparent Power (VA)

Therefore, Real Power (Watts) = Apparent Power × PF = Voltage × Ampere × PF.

Ideally a PF = 1, or unity, for an appliance defines a clean and a desired power consumption mostly Household Equipments (The dissipated output power becomes equal to the applied input power).

In the above formula we can see that if PF is less than 1, the amperes (current consumption) of the appliances increase, and vice verse.

With AC Resistive Load, the voltage is always in phase with the current and constitutes an ideal power factor equal to 1. However, with inductive or capacitive loads, the current waveform lags behind the voltage waveform and is not in tandem. This happens due to the inherent properties of these devices to store and release energy with the changing AC waveform, and this causes an overall distorted wave form, lowering the net PF of the appliance.

Manufacture claim that the above problem may be solved by installing a well-calculated inductor/capacitor network and switching it automatically and appropriately to correct these fluctuations. A power saver unit is designed exactly for this purpose. This correction is able to bring the level of PF very close to unity, thus improving the apparent power to a great extent. An improved apparent power would mean less CURRENT consumption by all the domestic appliances.

So far everything looks fine, but what’s the use of the above correction?

The Utility Bill Which We pay is never based on Apparent Power (KVA) but it is based on Real Power (KW). The utility bill that we pay is never for the Apparent Power- it’s for the Real Power.

By Reducing Current Consumption Does Not Reduce Power Bills of Household Consumer.

Study of Power Saver in Domestic Load

Let us try to study Household’s Reactive-Resistive Electrical Load and Voltage Spike Characteristic by example.

1. Power Saver in Reactive Load of Home

Let’s take One Example for reactive Load: A refrigerator having a rated Real Power of 100 watts at 220 V AC has a PF = 0.6. So Power=Volt X Ampere X P.F becomes 100 = 220 × A × 0.6 Therefore, A = 0.75 Ampere

Now suppose after Installing Power Saver if the PF is brought to about 0.9, the above result will now show as: 100 = 220 × A × 0.9 And A = 0.5 Ampere

In the second expression we clearly show that a reduction in current consumption by the refrigerator, but interestingly in both the above cases, the Real Power remains the same, i.e. the refrigerator continues to consume 100 watts, and therefore the utility bill remains the same. This simply proves that although the PF correction done by an energy saver may decrease the Amperage of the appliances, it can never bring down their power consumption and the electric Bill amount.

Reactive power is not a problem for a Reactive Load of Home appliances like A.C, Freeze, motor for its operation. It is a problem for the electric utility company when they charge for KW only. If two customers both use the same amount of real energy but one has a power factor of 0.5, then that customer also draws double the current. This increased current requires the Power Company to use larger transformers, wiring and related equipment.

To recover these costs Power Company charged a Penalty to industrial customers for their Low power factors and give them benefits if they improve their Power Factor in. Residential customers (homes) are never charged extra for their reactive Power.

2. Power Saver in Resistive Load of Home

Since a resistive load does not carry a PF so there is not any issue regarding filtering of Voltage and Current, So Power = Voltage X Current.

3. In Voltage Spike / Fluctuation condition of Household Appliances

In above discussion simply proves that as long as the voltage and the current are constant, the consumed power will also be constant. However, if there’s any rise in the input voltage because of a fluctuation, then as explained above your appliances will be forced to consume a proportionate amount of power. This becomes more apparent because current, being a function of voltage, also rises proportionately. However, this rise in the power consumption will be negligibly small; the following simple math will prove this.

Consider a bulb consuming 100 watts of power at 220 volts. This simply means at 240 volts it will use up about 109 watts of power. The rise is just of around 9% and since such fluctuations are pretty seldom, this value may be furthermore reduced to less than 1%, and that is negligible.

Thus the above discussions convincingly prove that energy savers can never work and the concept is not practically feasible.

What happens when Power Saver is installed?

The Fig shows the result of using Power Saver. The air conditioner (which has a large compressor motor) is still consuming reactive power but it is being supplied by a nearby capacitor (which is what is in those “KVAR” boxes). If you were to mount it at the air conditioner and switch it on with the air conditioner plus you sized the capacitor perfectly, then there would be no reactive power on the line going back to the fuse panel.

If the wire between your fuse panels is very long and undersized, reducing the current would result in it running cooler and having a higher voltage at the air conditioner. These savings due to cooler wiring is minimal.

What happens when Power Saver is installed
What happens when Power Saver is installed

A further complication is that if you install the “KVAR” unit at the fuse panel, it does nothing for the heat losses except for the two feet of huge wire between the fuse panel and the utility meter. Many KVAR units are marketed as boxes that you install at a single location.

If your power factor box is too large, then it will be providing reactive power for something else, perhaps your neighbor.


Power factor correction devices improve power quality but do not generally improve energy efficiency (meaning they would not reduce your energy bill). There are several reasons why their energy efficiency claims could be exaggerated.

First, residential customers are not charged for KVA – hour usage, but by kilowatt-hour usage. This means that any savings in energy demand will not directly result in lowering a residential user’s utility bill.

Second, the only potential for real power savings would occur if the product were only put near in the circuit while a reactive load (such as a motor) were running, and taken out of the circuit when the motor is not running. This is impractical, given that there are several motors in a typical home that can come on at any time (refrigerator, air conditioner, HVAC blower, vacuum cleaner, etc.), but the Power Saver itself is intended for permanent, unattended connection near the house breaker panel.

And certainly not in the way the manufacturers recommend that they be installed, that is, permanently connecting them at the main panel. Doing that drags the power factor capacitive when the inductive motors are off and could create some real problems with ringing voltages.

The KVAR needs to be sized perfectly to balance the inductive loads. Since our motors cycle on and off and we don’t use the air conditioner in the winter, there is no way to get it sized properly unless we have something to monitor the line and switch it on and off capacity (capacitors) as necessary.

Adding a capacitor can increase the line voltage to dangerous levels because it interacts with the incoming power transmission lines. Adding a capacitor to a line that has harmonic frequencies (created by some electronic equipment) on it can result in unwanted resonance and high currents.

For commercial facilities, power factor correction will rarely be cost-effective based on energy savings alone. The bulk of cost savings power factor correction can offer is in the form of avoided utility charges for low power factor.

Energy savings are usually below 1% and always below 3% of load, the higher percentage occurring where motors are a large fraction of the overall load of a facility. Energy savings alone do not make an installation cost effective.

    Many are trying to scam us out of our money; Solar is two exspensive to own unless you have 100K up front (or you finance), and still excess power back to the grid is non-reimbursable in TX.

    I write this comment bases upon my 39 years of engineering experience and with a bsee plus registration as a professional engineer in Texas and Oklahoma.
    The explanation using engineering terminology will only confuse the average individual who has zero background n engineering. About 1985, I was tasked with evaluating a device similar to the Stop Watt. I compared the energy consumption of various loads with and without the so called energy saving device and found no difference which could be documented. This should be all that is necessary to prove the device is a scam. There is also an IEEE paper issued in 2022 which performed tests similar to ones I performed in about 1985, which determined the so called energy saving devices are a scam.

    Jignesh, your coverage of the facts was quite informative. Bottom line, residents pay for power. Lines losses in homes are small, and can’t be compensated for with such a stupidly small device, and would be prohibitively expensive for the cost of building a real working phase corrector low pass filter. The Power Department does phase correction for the transition lines where losses are substantial.

    There is nothing complicated about this issue. ANY product selling for $100 or less that claims it can reduce your electric bill without eliminating appliances is simply a scam. On a similar note, products selling for about the same amount claim to double or triple your gas mileage. Over the counter drugs claim to treat heart disease, cancer, etc. The axiom is simple, If it’s too good to be true, it is not true.

    Is it safe to leave the Power Savers plugged in while the home is unoccupied?

    Aug 17, 2023

    I have an oversized kitchen. My countertop has several outlets for the following.
    Coffee percolator, K-Kupp Coffee maker, Air Fryer, Microwave and Toaster Oven.
    If I use more than one appliance at a time- my main circuit breaker or the GFI
    would trigger and disconnect. Although I have saved very little on my energy bill the
    Pro Power Saver ended the loss of power, allowing me to use multiple devices at
    the same time.

    First, unplug your lamp and change the wall socket. There’s a short, which can cause an electrical fire. You may even see some black soot around the plate. Outlets are very inexpensive and can be purchased at any big box store. They are easy to install.
    When you’re dealing with electricity, there’s always a chance for electrical shock.

    Good luck..

    I’ve been using these so called plug in power savers, all over my home, including one next to my circuit breaker, in the basement. I’ve had them for several years.
    I find there is no difference in my electric bill.
    If I could afford it, I would switch to the solar panels. Unfortunately, I’m retired and on a fixed income.

    Thanks for your insightful article.

    I want to know what is happening, technically when you plug a lamp into a household socket and you see sparks, same if you unplug it, seeing sparks. The obvious, it’s extremely deadly because of the fire risk. But what about electric shock? At 1 rental this happened in, I was told the electrical box is old and bad and that it is drawing more electricity than the condo needed. The landlord didn’t want to fix it, too expensive. I moved, but not before I told every neighbor around me, they might lose their home due to fire.

    There is a response to these “Magical electric saver” devices that actually purchased one and dissected it. The pictures show that the supposed “capacitor” that was saving energy was not even fully connected to the electric lines. The device was simply a resistor and LED to provide the green light. I think most of the evergy saving people see on their bills is due to seasonal weather changes that change the need for AC or Heat. I was a utility energy that tested power factor for consumers, worked to improve it and was responsible for voltage management at utility substation.
    These devices are a method to separate the buyer from some of their money.

    • Mimi Hunt

      So if these electric power savers do not function as they should, why are they still in the market, this is a scam. This is basically stealing money from clueless customers. We all should put a stop on useless electric power savers, or file a class action lawsuit.

    A good explanation but I do not understand this statement.
    “Moreover, a power saver also removes any type of carbon in the system, which facilitates further smoother flow.”
    What carbon can there be and how can it be removed by this?

  19. Alix Remponeau

    Interesting article. In my situation, the power company delivers fluctuating voltage from 220 down to 140 quite frequently. I purchased an AVRDSA3000VA to help stabilize the voltage I feed my home telecommunication equipment and desktop.
    When I use the AVR, my bill increases drastically. I suspect that increase to be caused by the work it does to maintain 220v. At 13 pesos per killowat, my bill jumped from about P4000 to P5000 and 6000 occasionally. In essence, by delivering a lower voltage, the utility company gives itself a raise. It gives less, but gets paid more.

    I would love feedbacks on this situation.

    Industrial capacitors work to improve PFactor for the power suppliers. The more motors, the more KVAR is needed. The most efficient system uses properly sized capacitors located at the terminals of the motors. Usually, this application is appropriate for systems that are powered by generators to improve efficiency.

    • Donald Kelly
      Mar 15, 2023

      Well said. In the majority of households, bills are based on KWH only, in higher demand homes, there may be multirate steps home). Most utilities may use a peak KVA (over shortened periods) as done with industrial cases. Why bother?. Note that large motors, (200KW), and short power outages ,the capacitors can cause up to twice normal starting torques than would occur without capacitors. I have analysed such a case.

  26. Tom Clement
    Feb 10, 2023

    The article appropriately debunks the idea that reducing spikes in an electrical circuit would significantly decrease your electrical usage. But it’s sad that it claims (several times) that “a power saver also removes any type of carbon in the system, which facilitates further smoother flow.”

    This is, of course, nonsense. An electrical circuit doesn’t have “carbon” in it that could be removed by a capacitor. Perhaps the author meant to say that if the claims of energy savings were true, then overall release of carbon into the atmosphere by burning of fossil fuels would be reduced. Yep, that would potentially be true if the premise was correct (which the article debunks). But could someone explain how a capacitor can “remove any type of carbon in the system”? Geez!!! The things people write and the things people believe!!!! It’s really discouraging.

However, I also understand that the way it was explained was quite confusing due to that fact…However I will probably purchase a couple of these units and try them out for the winter just to satisfy my curiosity. I have a whole house generator so don’t really need these items. However my curiosity has killed my cat so to speak. So, in the long run I will purchase a couple of units, probably three of them, install them as directed and test them out in my home. If they work, they work. If not for what they are selling for I won’t consider the investment a loss.

      • Donald Kelly
        Mar 04, 2023

        the article is even, without the carbon, ignoring facts. these devices are capacitors which store energy in one half cycle (0.008 second at 60Hz) and return it to the supply in the next half cycle (inductive loads do the same but with lagging vs leading current. these gadgets near the meter do not change the downstream load, except for minor changes to the supply voltage at the meter. To be effective they must be adjacent to the inductive loads. Note also that for the location at the meter, the capacitances reduce the power factor when little or no inductive loads are present. on a quiet night with all lights and appliances are on, pf would be near 0. By the way, avoiding low pf helps but typically in cases where this important, averaged peak KVA is a betterIn industrial and some commercial situations, putting capacitors near large or continous or large inductive loads does help as that does reduce kVAR . For households where typical bills re based on KWH there is no need to spend the money on these devices.

      I have to admit that it has been well over 60 years since I complete my electricity courses as a physics major in college. Still this comment makes no sense to me. How does an electric circuit lose carbon? Are the power companies actually using carbon core wires in their transmission lines now? Even if they are, where does the carbon go? I have the adapter on my junction box to allow me to input my own electricity but I’m waiting for a HUGE drop in fuel prices.

    Someone on the internet busted one open to examine the guts. The unit is comprised of one (1) 100µF, 150 VAC, 60Hz electrolytic capacitor and an integrated circuit that controls a light emitting diode (LED).

    Residential homes are mainly comprised mostly of resistive load as indicated by the high utility power factor. The best way to provide “cleaner power” is to increase the load power factor by adding capacitance to counteract inductive effects (motors, switching power supplies, etc.). Because capacitive reactance is readily absorbed by the utility infrastructure, these components must be placed as close to the load as possible.

    A typical residential household uses an average of 2000 watts each hour at greater than 0.95 power factor. Each Pro Power Save unit effectively adds a 540 VAR (Volt-Ampere Reactive) component to “clean” the power. A detailed calculation (kVAR = Real Power (kW) x [(tan(arccos(original pf))) – (tan(arccos(target pf)))]) proves that 137 of the “Pro Power Save” units would be required to increase the power factor from 0.95 to 0.96. *IF* the units are spread equally across both legs of the 240V service, a customer could possibly save $.000059268 for each kWh of power usage. (This is based on $0.10/kWh cost of base power).

    Under these optimum conditions, a customer would recuperate the $6,713 spent for 137 units after using 113,265,168.4 kWh. At 2000 watts per hour, a customer’s monthly bill should reflect approximately 1,440 kWh; therefore, it would take 6,555 years to recuperate the cost of the Pro Power Save units.

    However, if a customer just wanted to feel “greener” by installing only one (1) Pro Power Saver unit, the $49 cost would be recuperated in 47.8 years of use… the warranty is only 90 days. This is a great scam.

      Mathew, overall you have given an excellent comment. However ,note that in a cycle , reactive VARs whether inductive or capacitive will be taken from the supply for half a cycle and returned in the next half cycle -net 0 over a cycle. Yes, There will be power lost in the resistance on the supply side of the “saver” but on the load side, it will have little or no effect. To have a good effect the saver shoud be as close to the inductive loads as possible, reducing the real power loss from the motor to the supply. Note also that the “saver” will be producing 540VARs day and night independent of household loads.

      Mar 10, 2023

      I must retract my previous praise. your calculation is wrong somewhere. Consider the triangle where VA =2000/ 0.95 =2105VA and the angle is arcccos 0.95 =18.2 degrees. The resultiing reactive Var =2105 times sin18.2 =657 VARs Subtract 540 VAR gives a new total of 117VAR the new value expressed as a complex number 2000+j117 which ,in polar form, is 2003 at an anglle of 3.35 degrees which leads to a new pf of 0.998 Adding more ‘ ower savers ” will reduce the power factor(capacitive rather than inductive )
      However most houses have 120/240 V systems with some loads at 240 V and other loads split between 2 120V main branches and “savers” would be on both branches. and the utility appreciate your gift. Agreed, putting one of these near an inductive load will reduce wiring losses slightly- not worth the cost or effort. Where I live energy charges are based on KWH only, one price per KWH up to a set total and an increased price above that.

    As a electrical engineer and one who has wired my 6000 sq ft house, there is no free lunch , these devices do alter your current flow but will not save much if any money.. Look for any air leaks and be sure your attic is well insulated. I installed foil between the rafters and loowered the summer temperature by 13 degrees and made the winter temperature much warmer. Insolation is the cheapest way to save money on electric bills.

    I have ordered a set of these devices. I’m no electrician, but I’m intelligent enough to deduct that something is amiss in my electrical system, because I am paying up to five times more a month than any home owner who has complained about their power bill. Therefore, it would appear that the marketers of these devices are playing on desperation since even those whining about a $150 electric bills (when mine is $350 for a 2,000 sq ft home) reflect a general concern about spiking energy bills.” An electrician inspected my breaker box and everything and said it’s all proper. So, if it’s a scam, it’s targeting folks like me. I cannot figure out what has created power bills that are 50% higher for the same usage a year ago, and at least 60% more than two years ago. My home has been hit with surges, which Dominion has addressed, but has not stopped it. If any of you pros could explain what I could do, I’d appreciate it. For example, does an upgraded breaker panel and breakers affect energy efficiency? In terms of those power savers, wouldn’t it be important to assign them to circuits on which higher power consumption exists? Otherwise, does breaker amperage (ie, 20 amp vs 15 amp, etc) on a circuit using multiple computer devices, entertainment systems, lights, etc. affect consumer anymore than a 10 amp circuit with a few of these? Sounds stupid, I know. But would I be better off segregating my devices or powered elements such them they are dedicated to different circuits instead of loading one circuit, and would that have any effect on the consumption/cost of electricity? ?These are basic homeowner questions that I believe should be addressed, and whether any power saver devices should be plugged into multiple circuits. In my view, I could see that my home (built in 1975) may have electrical systems that may not have the efficiency of newer systems, 12-2/3 14-2/3, 10-2, 6-2 circuits notwithstanding. Please address this, because the monthly electricity bills are breaking me. Thank you, gentlemen.

      I think you’re digging too far into the weeds for an excessive household power problem. Don’t know what power plan you have with your utility but some plans involve an excess charge for going over a set rate and it will be stated in your utility bill. Some utilities have house energy inspections at no cost where the inspector will use heat sensors to detect conditioned air leakage around the exterior of the house. Did you buy an e-car that requires a special household transformer ? Have you bought many consumer appliances. that need transformers ? A transformer, although small, adds up with other “vampire” transformers.. Maybe try putting your chargers on a switchable power strip that can be shutoff when not used. Has regular maintenance been performed on the heavy demand appliances, like frig, freezer, etc.? The motors and coils should be vacuumed once a year. Furnace and air conditioner filters need to be replaced. The other alternative is to buy electrical timers for heavy demand appliances that shutoff during set intervals, like a frig at night which stays cold for half a day without power. Open window blinds and shutters during the day for light. Buy a manual carpet sweeper to substitute for a powered vacuum cleaner for regular cleaning – you get added benefit of some exercise. Powered dental irrigation can be replaced by a purchased hose device you attach to the sink or showerhead and you will have practically endless supply of water.

    Years ago, I worked in manufacturing as a supervisor at a Fortune 500 Company. The plant had lots of motors. Motors with very light loads have low power factors. The demand factor for peak loads can be as high as 50% of an industrial bill. Our power factor was below 92%. We were given 90 days to get it up to that value or pay a demand surcharge based on PEAK KVA. We analyzed each motor’s load. If the 5 HP motor could be replaced with a 3 HP motor, it got replaced with the smaller motor. If the 3 HP motor could be replaced by a 2 HP, it was replaced. Every motor in the plant was optimally sized to the load. We avoided the extra charge.

    It’s an excellent article by Jignesh. I am a retired electrician and for forty years worked at a very large industrial site that used a great deal of electrical energy. The majority of energy used was for large industrial motors, so to help with power correction to help reduce current demand, a power correction unit was built on site. It was a bank of very large capacitors.
    Power correction in the domestic home is a waste of time and money.

      This is an excellent article and certainly not drivel! Unless of course you are a seller of these devices!
      To put it simply for you, yes these devices are a waste of money although technically they are not a scam as the have a function in the power correction factor and some limited protection of equipment.
      In summary they are more of a deception than scam in that they will not actually save you money if your are a domestic user as your meter will always charge you for actual power used rather than reactive power.

      • Jerry Wakeen
        Oct 14, 2022

        Good job Paul. Reactive power vs Real Power is the main point. The power companies already correct the power factor by adding capacitors around their grid. The idea is to reduce reactive current by bringing the power factor closer to one, that is away from an inductive load toward a resistance load. This reduces losses in the lines and power companies have long long lines. You can see the relatively small capacitors hanging on power poles, not every pole but now and then. Smaller than the transformers that is. The typical home owner does not benefit because the meter is reading actual power used and not reactive power. Also the wiring in the home is not as long or carrying the loads that the power lines do, what is a fine tuned solution for a power company is negligable to a home owner. A “hard start” kit for a heat pump comes close but it is just a help for the compressor to get started.

    What power companies are charging/penalizing for poor power factor on a residential service? Sure, it could help with some of your motor loads, but like pointed out by another writer, you only clean half of the circuit with a plug in unit. You would need two and be sure to plug into each leg of your 240v circuit. Waste of money.

  58. Donn Hilton
    Sep 09, 2022

    People should understand that all homes have two phases of power coming to their home. Each phase is 120 volts and go to your basic wall outlets and your lighting. Combined the phases make 240 volts which go to things like your electric stove, water heater, that sort of thing. If you are to correct the power factor then you have to do it for both phases. By plugging a little unit into one outlet that will only do half the job. Power factor correction for industrial applications has been around for over 50 years.

I am trying to reduce expenses in my home and was looking at one of the devices for sale. It mostly sounded logical but there were things that made me doubt it’s value. For one thing I do not trust the phrase “up to”. If one is guaranteed to loose up to 10 pounds, loss of even 1/4 pound meets the “up to” criteria. I was glad to locate this post where the item was discussed without brand names. I almost understood most of it as all technical terms were explained. Thank y’all again.

    Hello Everyone,

    All electrical systems are different in people’s homes due to the many electrical contractors that have to install the systems differently and use different electrical equipment due to patents. Some will save 0% and some will save 90%. This leads to chaos which leads to stability. Read chaos theory on the internet. I have installed a power saver and I also have solar panels. My power saver is allowing my solar panels to produce electricity at night with solar neutrinos in addition to daylight. Look up neutrino solar panel technology. My solar panels are manufactured as neutrino solar panels. Some solar panels will not work to produce power at night. I produce 6500 kWh/year with sunlight and 8500 kWh/year with solar neutrinos. A person needs a specific type of solar panel and power saver to produce power at night with their solar system and neutrinos. I currently save 30% on my electrical bill because of this. My question is are there any people in the US who also experience this? I am writing a science paper on this and I am going to publish it if I can find 100 people who experience the same thing. If you want more information then contact me at my email address of [email protected]. I have found out that if someone pays a lot for their solar panels then they might experience the same thing that I do and if they paid less for their solar panels then they might not experience this due to the less expensive solar panels not being manufactured to provide this benefit. My theory is that everyone eventually pays the same amount for their electricity over time no matter what they do.

      Jingnesh is right, These ‘home power savers” are not worth buying -particularly when placed near the meter. There are many claims for these devices that are nonsense. They take some known information and then go into fairyland.. Some try to tie them to Tesla, who was a 3 year old when the principle was first analyzed.. Another has a 300KW rating but plugs into an ordinary 15A 120V socket ..

        With regard to my last comments, The monetary benefit depends on how your electric cost are determined by the type of meter in use..Some meters only record real power. (or are set to do this. My home meter is electronic but I am billed only on KWH. Other meters measure KWH as well as maximum KVA in a time (typically 20 t030 minutes). Originally these were not used for homes, but now,in high demand homes and cheaper meters that may be done by some utilities..
        All the graphs that are presented, do not show the instantaneous power in a cycle (60 cycles/msecond). nor do they show that the average over a cycle
        Check your bill.If it shows only KWH related information -there is no effect on the bill. If there is both KWH and Max KVA, there is a monetary saving.due to a better power.factor.

    Well I read all the negative reviews but I must disagree; they actually worked GREAT for me. I have a small house (650 sq’) and I just got a notice that my 12 month averaged bill is going from $140 a month to $105 a month, based on a 6 month review. I noticed a 19% reduction the first few months after installation (2), but now it’s at 25% reduction. I have 2 AC window units, and a stand alone indoor AC, used moderately this past summer. And a oxygen Concentrator that runs 8 hours a night. They refunded me $43.75. Which almost paid for the 2 that I bought ($50). Now I notice the same units are selling at WMT for $10 – LOL. Saving 25% each month is fine with me !!

      Jan 26, 2022

      Does the outside temperature vary over the year? It takes a lot ore energy to cool from 90F to 70F than it takes to cool from 75 to 70. This will have much more of an effect on your bill than the “power saver” . I assume the indoor AC unit has a tube to vent the air out of the room. If not, it is putting more heat into the room than it takes out. This is basic thermodynamics.

    As a consumer of the Power-Save ABET 2201 product in my house, I have a hot tub w/jets, pool w/filters, several refrigerators, freezer, 2 microwaves, forced hot air, hot water heater, toaster, gas stove, 2 washers, 1 dryer, 2 air conditioning units, 1 dehumidifier, many TVs, many computers, 5KW solar panels system, and a standby generator that kicks in whenever I lose power + 1/week for maintenance. I also have a eco-monitoring system so I can tell what lines are consuming how much electricity. I have a lot of stuff. I was told by the installer, that the capacitor would reduce costs by reducing spike demands as the capacitor would help condition the line. Exactly how much he could not say. What was explained to me was that the Power Company charges you monthly based on the highest Amperage you draw to determine the KW you will be charged for. They monitor the highest draw and use that in the calculation, even if it was only for a small fraction of the time. So no, I do not believe the capacitor in these devices supplies significant power to make up the amperage draw. I would need to install a powerful battery bank (tesla option?) to supply power nightly when the solar panels are not producing to insulate myself from power company charges. The solar panels+capacitor did reduce my monthly bill from $350/month to $150/month on average. However, there is a gotcha. The original power saver eventually burned out. When it did, it became a sink and kept drawing excessive power. My monthly bill went back up to $350/month, even with the solar panels. Not being an expert, I was not sure what to do. I turned off the power saver and the bill returned to close to normal. I have since re-installed a new power saver, but now I know these are only good for the warranty period and to keep an eye on it.

    So I guess it depends on how many motors you have in your house and when they turn on. I have many different devices, not counting the occasional power tool.

    And maybe I was fed a line of bull about how the power company assesses your monthly charge but that has yet to be disproven.

        Just done the calculation, it’s 119w however as the filament is brighter and hotter the resistance will increase which will lower the power drawn slightly.

          Jul 16, 2021

          Yea for Nick and the resistance of the tungsten will increase more than one might think so it will be closer to 115 than 109 or 119 with a 20 volt increase on the tungston

      • Jim Kirk
        Nov 13, 2021

        No – this wrong – you cannot use the same current value to calculate power after you change the voltage. The current is dictated by voltage by Ohms Law I = V/R

        So at 220V / by the current 0.454A = load resistance = R – 484 ohms which is constant.

        Now V – 240 / R – 484 = I – 0.495A

        So the power drawn by a 220V 100W bulb when the voltage is increased to 240V is

        P = V x I = 240 x 0.495A is 119W

        Using P = VI simply does not work.

        Getting back to the original issue – Power factor correction at the fusebox is always beneficial irrespective of VAR metering because reducing the Reactive power also redcues the True Power which is measured by the domestic meter, but it would be very expensive to install in domestic situations and would not be financially viable.

        Power cleaning is installed at the point of use of equipment – it will save a small amount of money but is normally used to protect vulnerable equipment (computers) from waveform spikes. This has been overtaken in the UK by the 18th Edition regulations which requires Surge Protection to be intalled at the fusebox.

        Power Conditioning is installed at the supply position and is a great energy saver as well as protecting equipment. It involves using capacitors to chop the peaks off the waveform at 230V. (In a 230V supply the peak voltage of the waveforms is 325V, therefore there is 95V of wasted energy on each cycle which is paid for by the customer It requires a large amount of equipment for a 230V 100A supply, would be very costly to install and dumps high values of power down the earth conductor – it is not permitted.

        This is what the Voltex energy savers claim to acheive

      There are other issues with the article but that doesn’t change the fact that these plug-in “power saver” devices are scam products which will have no measurable effect on people’s energy usage or electrical bills.

      Those suffering from voltage spikes due to fluctuating distribution line voltages in their area should have an electrician install a whole-house surge protector into their main electrical panel.

      People who wish to reduce their monthly electric bill would be wise to invest in grid-tied photovoltaic solar from a reputable installer.

    • Mr. Tracy Malloy
      May 29, 2021

      I’m an electrician and electronics technician and I am rather surprised at the numerous significant errors in Jignesh’s write up given his alleged electrical background. He is correct that these devices are garbage and my calculation is the device could only save you $3-$5 Can or USA funds per year if it was plugged in 24/7. It has an approximately 2-3 microfarad capacitor inside which does all the savings work so these stories about saving 50-60 dollars a month are impossible unless you plug in 25 of them at a time. There is no carbon in the circuit and the case for spikes he mentions is exaggerated if he means a North American power source. The device does not store energy and use it later either and these are only a few of his numerous errors which I did not think an engineer could make. The 25-40% savings is the manufacturer’s misleading statement which is possibly referring to the lagging low power factor of split phase or shaded pole motors in the home but this device will not fully correct all of the low power factor. If you bring your power factor up to unity, then any of the additional dozens of power savers plugged in will likely consume power and increase your bill.

    I bought one of them for my apartment. Just plugged it in and forgot about it. After one month, my electric bill dropped from $128 per month to $67 per month. I don’t know what anyone else’s experience has been, but it literally saves me $60 bucks every month since I’ve had it.

That is the most outrageously ridiculous thing I’ve heard in days. Nope. There is no carbon to remove in the first place… where is the carbon? Show me the Carbon? Sheesh… dumb, dumb, dumb.

    I note that marketing for these devices is full of phrases like “you may save” or “as much as” which are red flags that at best, the devices are engineered for averages, and with the wide variety of devices in homes as well as types and size of residences, it is very unlikely that any one person will see any significant difference. My power bills vary from month to month based on temperature, how much I am home to run appliances, and many other factors making it very difficult to determine actual savings.

  104. Joshua Billing
    Apr 08, 2021

    Yeah, as soon as I read that it corrected Sine waves with capacitor technology, (and that is paraphrasing by taking the vague descriptions of what they claim the device does to save you money, put them all together, filtering out the nonsense and crap, and reduce the claims down to the lowest common denominator) and you are left with a magic box that SOMEHOW filters power from just one outlet near your supply meter, and corrects ALL of the power in your house even though all of the appliances, lights, outlets and etc aren’t all on one breaker? It’s a freakin miracle!! They should call it the Jesus Gigawatt Box!! So they basically think we are dumb enough to believe that all of the electricity in our house will filter through this box at some point in the circuit, or that the electricity is just radiating everywhere around us, and like a giant ghost trap( ala Ghostbusters) this device pulls in the energy all around us that is being emitted through our walls from electrical wires? It will also cut down on the radiation emitted from said wires? Wow… I had no idea that governments around the world were pumping in such dangerous radiation and stealing money from us, and the hair on our heads doesn’t even stand up or we don’t build up electrical charges simply by moving through the charged particles that are coursing thru our homes in great enough amounts to shoot electric fireballs at one another.. Seriously, if 30% of our power bills was just wasted electricity, lost inside our homes and residual dirty carbons coming thru our electrical wiring, the crisis these power companies would be concerned with wouldn’t be the money they could potentially lose, it would probably be the millions they would potentially kill because of their product, and the trillions in property damage caused each year… I know my science isn’t even remotely close to accurate, I’m merely explaining all of the crazy thoughts in my head watching the infomercial for one of these products.. I am just amazed that claims like this could be made, and products that are so clearly BS, and evident scams can be freely marketed, even when every scientist with a basic understanding of the principles of electricity is screaming scam at their TV’s in millions of homes in the USA.. Why do we have so many types of crime investigation bureaus for every other kind of crime, but no agency looking into Snake oil salesmen? It makes about as much sense as the science that makes this product sell

  105. John McHugh
    Apr 07, 2021

    The Voltex device adds claim that the device is patented so I asked for the patent numbers, reminding them that falsely claiming a patent where none exists is a crime. The reply:
    “Patent is very complex thing so in order to be able to sell in multiple places the company decided to risk it for the expansion. We assure you that all of the item we sell is secured and made with high valued materials.” This appears to be a power factor correction device, at best, and will probably not alter your electric bill unless your power company has very strange metering.

  106. Malcolm Metcalfe P.Eng.
    Apr 04, 2021

    It is very hard to believe that this was written by an engineer. For example – the calculations on the refrigerator are wrong. The current is not calculated correctly – AND while correcting power factor reduces reactive power (kVARs) it does NOTHING to the WATTs consumed. Residential customers almost everywhere in North America do NOT pay for amps, VARs or kVA – only for watt-hours. The ONLY change to a bill would be the result of a small loss in the house wiring caused by reducing current – but that would almost certainly be less than 5% unless the power factor was far less than 70%.

  107. Dan
    Apr 01, 2021

    I almost agree with you 100%, but don’t forget about losses. Although your electric bill won’t see any noticeable change, there is additional energy lost (heat) from the spikes and waveform distortion. This is due to the fact that most circuits are designed to pass low frequency waveforms and filter the higher frequencies and spikes caused by various inductive devices. As an example, if you have a good quality power strip, you may notice that it gets a little warm. That is the filtering built into the power strip. For those of you that are yelling scam, the part you are misunderstanding about this article is the operational power saver device which when applied correctly works very well but has no impact on your home utility bill. What the article is trying to tell you is that even if you get a working device, it won’t change your utility bill because you are billed on ACTUAL power used which will be the same regardless of whether or not you have PF correction. PF devices are primarily used in manufacturing facilities and are charged for peak current which is a completely different ballgame and unrelated to residential utility bills.

    When there is no customer service or support email for device, don’t waste your time on it.
    Here are my “common sense” questions to ask about power savers.
    I would not spend even a wooden nickel on these devices!:
    Hi whoever you may be,
    Your product is certainly every enticing. However, I have yet to find any information on the Web that gives me reason to invest.
    First, I do not understand how your product is related to Ohm’s Law.
    Second, as far as I know, my energy costs are based upon a measuring device outside my home to calculate how much electricity/energy I am using. How does your device (or devices) interact with this Electrical Meter? It would seem logical to have some kind of surge protector/regulator outside the house, before the electricity enters the counter. How does your device affect the quantity coming into the house? Or does your device affect the electrical demands of the devices in their start-stop cycles? (I do recall that many years ago there was a big rush to leave all lights on in skyscrapers because turning the lights on took a greater surge and thus it was less expensive to leave them on.)
    Third, you say “there are no electricity saving benefits for heating appliances, such as electric stoves, electronic cookers, etc.” So wh;y bother with your device? Please elaborate on the “etc.
    I have 3 wine coolers, 3 refrigerator/freezers, 1 freezer, 1 built-in stove-top, 1 microwave oven, and 1 convection oven; plus several induction burners. Most are commercial.
    Fourth, I do not understand the reasoning for the geometrical layout for the placement of your devices: on or near the main breaker box, and the rest at 500 sq. ft intervals. How is this to be measured if your rooms are larger or smaller than 500 sq. ft? And why square feet? Doesn’t make sense.
    This is really a great scam and too well presented in the manner of “Trump”

    My mom in law bought power saver from Amazon. And plugged it in to save money on electric bill. Hubby tells me that it’s fake. Daughter tells me that we should return it.
    There are 2 plugged in and 3 sitting on a table. I don’t know if it works ❓

      These power savers are 100% fake. The day I got mine , the thing screamed fraud. So since I bought three, I decided I would open one up and take a look inside. There are two lights and two Ted wires going into a black box filled with clay. I cut the black box apart and discovered what I thought might be resin was instead just clay. I cut it apart. Guess what? There is no capacitor, there is nothing! The wires are just stuck in the clay connected to nothing. This is one hell of a fraud.

    despite all the discussion about KV and KVA and cleaning up voltage and current, nobody has addressed several basic questions:

    1- How does plugging one of these “devices” into an outless anywhere in the house affect anything at all plugged into different circuits and different outlets. The “explanations” in the artile and in the desperately positive comments seem to be base on the idea that there is just one line connecting all the devices in the house in serial. In fact, the devices are all connected in parallel and while there may be interactions between the amount of current flowing through different devices connected in parallel, plugging a box with a few capacitors into on outlet does not immediately come to mind as a way to dynamically influence anything going on with all the devices drawing power from all the other outlets – whether on the same circuit of different circuits.

    2- The article says it takes a time (a few days, weeks, or months) for this device to “figure out’ how to reduce your measured (actual Kv) power consumption. I am not an electrical engineer, although I have had some education in electrical and electronic theory, the former involving moters and generators – and the effects of inductive loads on power meters. I cannot imagine what a box containing a few big capacitors, plugged into one outlet on one circuit on the house side of the meter, might be doing to incrementally improve efficiency after it is plugged into the wall. There doesn”t appear to be any “learning” component involved that would examine the wave forms for the voltage and/or current in order to tweak some algorithm (there is NO algorithm to be tweaked) and continuously improve the “cleanliness” of the voltage and current sine waves. Even if there were such an algorithm, something that monitored the noise on the voltage and current, and an algorithm (there appear to be NONE of these) then see question #1.

    3) How has this device and similar devices continued to be sold despite it obviously being a nonsensical fraud? The Federal Trade Commission should have shut down the sale of this device an others like it long ago – after, evaluating the claims about savings, the gobbledigook theory of operation, and/or even running some simple tests – with the help of the folks who sell these silly things, of course, just to keep it on the up and up.

    I believe certain power savers will work and there are those that are a scam. I don’t think a company would put a product out there and say it works without first having it tested and have used it themselves. This could lead to lawsuits especially if the device causes damage and can be proven. You just have to test it for yourself and if you are not pleased get a refund or it will just be a loss. The product isn’t that expensive and if it works you will profit on down the line get your money back in a few months.

    I’m a computer engineer, and this product is BS; Don’t waste your money! First the lines coming out of your breaker box are each on it’s own circuit, so that the refrigerator is on it’s own line, the hot water heater is on one of it’s own, the AC, microwave, and individual rooms etc.

    That means if you plug the Instawatt, or any such similar device into an outlet, the absolute most you could ever hope for is; That it might help that single circuit alone. So if you have 40 breaker switches in your breaker box, and assuming the product actually does function as claimed. You would NEED 40 devices to plugged into an outlet that is tied to each, and every single circuit in your house. It simply cannot affect any other circuit outside the one it’s plugged into!

    If you want to reduce the wear, and tear that spikes, and surges causes on your household electronics, and appliances. I would recommend a better investment. You can attain a home surge suppressor unit at any electrical store, near you, or order one online. Don’t be cheap as the better filtration provided by the unit the better protection you’ll get.

    I called city electrical supply in Brooksville, Fl, near my home, and they offer one for $175.00. I seem to remember paying just $40.00 only 10 years ago, and mine’s still going strong!

What if you cannot afford such a unit, will they turn off your service?? Answer: NO. What planet do you live on. This may be a requirement on Mars…not sure. Will have to check. My home have no such devices neither does any my rental houses. Truth being told electric co not interested if your house burns down…not their problem. Law enforcement doesn’t either .fire dept?! Nope, the president…nope. Dog catcher,, ah this must be the one….nope These are things you have to do on your own…..if you like. You do not buy such a unit before they turn on your service.

It will do zero for your bill and actually is liable to increase it due to the constant load of the LED’s. Most power companies do not charge you for spikes anyway.

    P.T. Barnum said: “There’s a sucker born every minute!” Well, he would of hated me! I’m the eternal skeptic that reads the annoying fine print, reads EVERY REVIEW, & painstakingly searches for the signs of misleading wording in representations of products.

    So, I would have been the guy, excitedly, pointing out which of Mr. Barnums displays were hoaxes. In fact, you’d of likely seen me being thrown out for it & later read my article about it as well.

    The bottom line: there are more than enough cues, tells, facts from electricians, & personal experiences from home-owners who’ve purchased the product, to easily make an accurate assessment of this product.

    For homeowners…these types of products seem all but worthless, with minimal savings. I’m ABSOLUTELY NOT GETTING ONE! Other people have reported a host of problems, with appliances not working properly, and so on.

    Not to mention the elephant in the room! Forget the outrageous claim that it would save homeowners nearly 40% on their heating bills! Think about it. If it really saved that much electricity (“budgeting it”, making it “Cleaner,” or however they want to phrase it, to put lipstick on their pig) IMAGINE WHAT THAT WOULD MEAN FOR THE ENVIRONMENT!!! GOVERNMENTS around the world WOULD BE MANDATING THIS, instead of inferior technologies, in housing EVERYWHERE! (In newly built houses of course, but their would be programs for existing homes) The WHOLE WORLD would be clamoring: “SAVE THE ENVIRONMENT!!!” & “STOP GLOBAL WARMING!!!”

      All of the reviews MAY be from people who purchased these items during a high load season, winter or summer. Then buyer evaluated the product when there bill were lower in the low demand season. These may be real reviews, which I seriously doubt they are only showing the high 5 star reviews and removing the 100 negative reviews for each positive. That is probably a conservative guess. If you search for reviews on product using Google or whatever browser you use and find all the links lead to the exact same add for the product you are trying to find unbiased reviews on, ” HERE’S YOUR SIGN “!

      Interesting math. Keep in mind, you have to use the first 800kw before you can get to the cheaper power. If you could reduce your power so that you never reached the 800kw limit, you would save money. For that matter, any reduction in electrical usage saves you money regardless of the rates unless going over the 800kw limit reduces the charge on all of your electricity.

      I am not suggesting any of these “electrical reduction devices” actually work.

    The person on the other end said that although their Co. has somewhat the same name as the electricity box Co. they are not affiliated with that Co.

    After reading the article on the “power saving” devices, I am astonished at the changes in the laws of electronics. If P=IE is still a law of electronics, then the KW per hours the electric company uses to calculate the bill should change if as in the example of the refrigerator are true. from a current usage of .75 amp to .5 amp should result in a KW savings as a refrigerator running on 220 v and .75 amp would equal 165 watts, and take the same Refrigerator running at 220 v and .5 amp would now be 110 watts. So the KW per hour would also be reduced. It is physics and the laws we were all taught about electronics. Now, I am not saying I believe or disbelieve the “power savers” work, but the examples given just do not add up.

    • Dalebert
      Jul 24, 2020

      Considering the voltage and current (0.75Amps) are out of phase, P=IE is not totally true. Multiply the power factor due to phase shift times IE, then the real power is 110Watts. The reason is that the voltage is high before the current starts flowing. For the first instant, voltage is high but current is zero, so the P=IE will be zero. Inductance (motors, coils,) are slow to react so current is lagging the voltage with AC.

      Sep 03, 2020

      Thanks for raising this doubt. While going through the explanation of this M.Tech guy having 13 years of experience, even I got confused with my basic understanding of physics lessons of xth std. where i scored 93%.

      None of that has changed… but electric motors don’t work the same as resistive loads. More of an issue for anyone billed for ‘power factor’.

    • Adrian Waygood
      Jan 27, 2021

      Ken: Your mistake is thinking that the equation for power is P = EI. In fact, it’s P = EI multiplied by the cosine of the phase angle (the angle by which current waveform lags or leads the voltage waveform. That is an IMPORTANT distinction. See article in for a full explanation on why power savers are a scam. And, incidentally, it’d kilowatt hours NOT kilowatts per hour ( no such thing).

    • Lionel Adrian WAYGOOD
      Jan 27, 2021

      You are using the wrong equation for power (it only works for d.c.). For a.c., it’s P = E i multiplied by power factor) .That is a very important distinction.

    The simplest way to save on electricity bills is to do the tasks yourselves instead of using electrical appliances. Do the dishwashing by hand instead of using a dishwasher.

      I’m not sure switching from washing plates and dinnerware, to using throwaway paper plates/plastic utensils will save money. It would depend on how much time/energy/money it costs to produce/distribute/sell the Paper/Plastic items.

      Jul 19, 2020

      You’re not thinking clearly, buddy.
      1. Dishwashers typically use less water than handwashing. They can process several meals’ worth of dishes, depending on the number of dish-users, saving on water-heating costs. They also save precious time. By the way, pre-washing dishes is stupid and unnecessary, beyond a light rinsing, if your dishwasher is any good. Wish I had one.

      2.Paper plates!!?? Aaaaaah! Super-wasteful of raw materials and money, and add to the mountains of waste. Where do you think “away” is, anyway?

      3. The only thing you say that makes real sense is to use blankets instead of heaters. Using heat when you’re in bed would be moronic, whether it’s household heat or electric blankets. An exception I use is a small heating pad for my feet that I turn on the lowest setting out of four before getting into bed and which automatically turns off in two hours. It saves me much discomfort from my typically cold feet, which would take easily an hour to warm up without assistance.

    • E Montville

      Using paper plates requires trees. We need to use less water and some dishwashers use less than if you washed them by hand. You have to think of the carbon use, not just using less electricity. It’s also a complicated problem.

    Many years ago, out in the country, we were the last residence at the end of a 240 volt, 2 phase line (hot, neutral, hot with 240 volts across two hot lines and 120 volts across either hot line to neutral comong off a 4160 volt dual line)(common in USA.). We found that ac units dropped out on hot days and fluorescent lights refused to start. My personal power meter showed voltage in the 113 volt range and lower on some days. Power co. Engineer did not believe me but after 3 calls in one week, he agreed to place a recording meter on the line. When he came back a week later, he had to apologise. Not only was the voltage seldom above 113 volts but it sometimes dropped below 100 for a few minutes each morning. After investigating, he discovered a business 2 places “up stream” from was using several notoriously inefficient motor driven converters to produce 3 phase power for his machine shop. The solution for the power company was to install two capacitors (one for each hot line) that evened out the flow and raised the voltage around the clock for us. They worked but they were not the puny caps put into these energy saver boxes. They were each larger than the transformers (that reduced the 4160 volt lines to 240 volts) and had to be mounted on a new dual pole rack up near line height. That engineer learned something that time… sometimes the customer really IS right!

    I had been working in energy efficiency more than 25 years, all those “magic savers” are a scam. Power factor correction reduces costs, but households are billed by kWh not kVA, you will save only in wire losses.
    The internal circuit in those energy savers most of the time has a semiconductor (diode or SCR) which inject Harmonic Distortion (THD) in the system making electromechanical meters to read less than real consumption (this is fraud), with electronic meters have no effect.

        I would like to know if this would be beneficial for a residential application where a 1HP motor runs all summer long for a swimming pool? Would you suggest only using it during the summer months when the a/c and pool are working?

        • Philip S Gilmore
          May 26, 2020

          Personally,, if you want to do this, calculate (or have a knowlegable friend do it) what size capacitor(s) is/are needed, then place this new unit in line between pump and power source and switch it automatically (relay or solid state relay) so that it is only online when motor is actually running. Keep in mind that 1 hp is approximately 750 watts plus motor inefficiency. Capacitor will level out the surges but won’t save money because residences are billed by kilowatt usage only. Also, due to the way ac voltage and current flow operate, the capacitor will raise your average voltage, perhaps higher than the motor is designed for. Home pool filters usually do not truly need 1 hp so there will be more inefficiency due to this than power factor correction. Manufacturers use one hp so that they can use one filter/pump assembly for most pool sizes that they make. You may save more if you install it on wire one guage size larger than spec’d – especially if the wire length is close to or over 100 ft.
          My opinon? Get rid of the pool and use someone elses’ pool. Think of the savings in chemical alone!

          Buy an Energy Star variable speed pump, they cost more but many electric companies give rebates as well as the manufactures like Hayward. From everything I have read and all the people talked to, the claim is that they save money. With our power company the electricity is cheaper from 9pm-7am Mon-Fri and all day Sat and Sun, so we run the pump very little during the higher priced time of day. I’ll be replacing our pump next May when the rebates come out, this is it’s 7th year which is average for how long they last.

            Really everyone, The only way to save money on electricity is to use less. Do you really belive that plugging in a $60 capacitor into a wall plug does anything? What you can do is run high draw appliances like electric dryers at the time of day when electric is cheapest. Typically the most electric is used 6 am to 9 when businesses open, machines start up, computers, lights, printers ect.. are fired up drawing a lot of energy. Usually 8pm ot later the draw is lower, thus the price is lower. People will find these electric cars are going to be expensive to charge. Whenever energy is converted from one form to another, there is loss in the conversion. So we have to drill for the oil/gas, and in some cases coal, transport it to the electrical plant, burn it to heat water to steam to run turbines that in turn run generators, then transport the electricity to your house, convert it down from 48k volts or whatever line you are on, then into your car battery. I count 5 conversions with losses of 10-30% depending on the conversion and efficiency of the equipment. So while electric cars are here to stay, are they envirionmental saviors? hell no, you just don’t see it like you do with a gas car. And do some research on what is in that battery (Super toxic heavy metals and explosive lithium) and how it is recycled, (It’s not). Be informed, I’m sure the technology will improve. But just be careful buying a used Prius that needs a battery replacement, you will be in for a big surprise.

    I had a friend back in the ’70s who sold such a device (and gave one to me). I was a 10″ square box that he told me to hook up outside at the electrical panel. I didn’t, but I did open it up – three capacitors (I don’t remember the uf values) and nothing else. What I remember about capacitors was that they are a ‘short’ to A/C, and an ‘open’ to D/C. So, (and yes a little bit of electronic knowledge can be dangerous!) I decided they really didn’t do anything and I tossed it. I did find a device that was used at the source (refrigerator) and it’s claim was that it reduced the frequency of the electricity to the fridge (after startup) to slow the motor down, because the thought was you really didn’t need all those revolutions for the fridge to do the job. So, less RPMs = less electrical usage. I really don’t think that one worked as well because of intermittent cooling demands. Now, my fridge has a variable speed compressor (digital converter, same principle) that not only saves $$$, but also varies RPM according to demand.

    You lot would be better off investing in LED lighting to save on power consumption and would also save you money in replacing lamps as they have a longer operational life span. Then after that you would be better off investing in solar panels and a good inverter or solar controller and battery and being off the grid.

    I think the author academically studied the subject and not understood the real purpose of capacitor resistance circuit to assist in power factor correction and surge suppression.
    He used carbon in electrical parameter , where he studied such terms to explain electrical energy.
    Putting his unsolicited non technical inexperienced novice theory in first google search for power savers will mislead lot of people believing his academic degrees.
    Without proper experiments and proof he explain the thing.

    • Stephen
      Aug 03, 2019

      Again, as above, the claim about carbon removal was by the selling company, not the author.
      In his explanation on how the system actually works he does not mention carbon removal at all.
      A shorting circuit will, of course, carbonise the shorting and arcing points but these cannot be removed by improving circuit conditions, only prevented.
      Further, the author dies not state this system doesn’t work but states that as long as the system is in operation at, and only at, the same time as the capacitive and motorised loads and to only the extent required, then it will work very well, but the system doesn’t reduce the billing on power consumption for industry effectively enough to outweigh implementation costs EFFECTIVELY and to not affect household billing at all since households are not charged in the sane way as industry given that industrial machines are penalised as being the CAUSE of the “dirty signal” in mains electricity.
      I learned long ago from an electrical lecturer that in the UK in order to clean up the signal on power in the National Grid that one power station would have to be ENTIRELY sacrificed to the cause.
      This would improve the power so well that the overall consumption would be reduced by nearly a half.
      Imagine the loss ou’d income to the power companies and how much they’d have to increase cost per unit to make up profit margin.
      This would cause uproar even though the overall cost to the consumer would remain the same as they’d see the increase wasn’t due to cost but profit (although use of that sacrificial power station would translate to cost, the public wouldn’t see or care about that) and they’d be angry and possibly start rioting over it (people can be volatile over some such things).
      Thus the cost is put into industry and the status quo remains.
      If every house and industry fitted these power saving devices to clean up the signal and they incorporated an additional activation/deactivation circuit fur when ac unit or fridge/freezer motors and industrial motors and charger units and power tool transformers were active/inactive, then the power station sacrifice theory would be unnecessary, the signal would be clean, the power consumption would go down, all at cost to industry and households (who weren’t being directly charged in single additional surcharge form anyway, only through annual rise in unit price), the power companies would continue to raise prices and unit charges and not tell everyone that they (the public) were the ones cleaning the signal but that it was the actions of they (the power company) at their own cost and effort with rising prices on wages and materials and continue to raise surcharge anyway..
      Thus the effective way to manage this is to cut your own bills and surcharges where you can and not spend money where it will do you no good regardless of effort or cost..

Of having this device, When i got my electric bill i found out that my bill go back as regular bill i ve recieved until now this devices still on the outlet where no one cant touch it ,but my electric become higher and higher than ever. Now the cost of my electric bill is 1200 pesos .wheni dont have this devise my bill only 800 pesos only 1 mo. This device makes me happy from 800 it become 400. And i bought this device here in your site at 2500 pesos . Can u pls explain to me what should i do to make me happy of this.thanks

    Power factor correction actually reduces power consumption, because every load is linked to efficiency. If 80% is efficiency of device then 20% are losses. Loss is calculated as I2R. If current reduces, correspondingly the loss reduces which saves power.

    • Krishnan
      Aug 23, 2019

      When power factor correction is introduced into the system the voltage and current in the transmission line is in phase and the transmission loss is reduced giving advantage to electric company not to the subscriber. Since electricity being saved by reducing transmission losses amounts to electricity produced, such devices may be encouraged if it works to avoid national wastage.

    • Suro
      Oct 17, 2019

      Power factor correction is about reducing the reactive power which doesnt do any work in the literal sense.. as the knowledgeable author said adding capacitive load may be dangerous as a power system may suffer from certain instabilities like self excitation at the alternator. So static var compensation is deployed to control the amount of var pumped in the grid. Jignes bhai rightly stated that identify and switch off wasted power. You can control. If you want that auto regulated.. use motion sensors to switch off in empty rooms… PLC like logo or diy like Raspberry pi can be used to switch of timed devices. For airconditioners we should use a larger capacity single unit instead of multiple to cool a larger area… probably best to interconnect the rooms and have a single unit cool to a temperature setting and switch off.. inverter acs can be the best answer. For heating sun is the best source.

    None of these so called devices work, at all. I have just shut down the third site maintaining that they work, they do not. On a Flourescent light in a factory there are reasons to fit a capacitor. In easy terms the capacitor brings together the current and the voltage. This is required because the electricity supply companies charge a premium for poor power factor, the relation ship between how far the voltage and current are out of phase with each other. The reason being that if the current and voltage are out of step then the power company have to supply more electric than is indicated. This can even cause connection failures. In a house the difference is immaterial. However, on new electricity meters even that is covered. So none of these boxes are any good, As for claims of spikes etc, well the only real way to stop the parasitic spikes etc is to use a proper item for example a Uninteruptable power supply that is working through internal transformers. So, if anybody tries to sell you one you now that the so called power boxes are a scam. I have just caused another to be shut down, it was called Ecovolt from eastonia. Read Fraud.

    As per Indian electricity act domestic consumers are to be billed on kwh basis hence reactivate power consumption should not be recorded by domestic energy meters but i am very much doubtful about energy meters provided by electric supply company, in my openion new electronic meters measure some reactivate power component also. I visited several single phase meter testing labs of power supply company and requested them to give demo for testing the meter at different power factors but equipments such as phase shifter RSS meter etc were out of order. And it is told to me by several responsible people that energy saver really reduced their bill up to
    some noticeable amount.This thing also support my claim that energy metere do count reactivate power. Now i will purchase one and see
    what difference it makes.

    only power saver 3 phases with a kvar capacitor and controller Power factor, c/k and more can true save, depends the inductives load. if good for hotels or place use for sample many air conditioner. here can get good result saving.

    for product picture you show yes many power saver , and aslo every power saver with a socket plug is are scam, and you can see china is number one place for scam power saver , same recently shenzhen jumbo power saver , product dont save only $1 and more him increase your bill electric .

    i use another factory form Taiwan use a true power saver 3 phases and i know 90% is are scam power saver, my for every customers i install power saver. i try with a meter 3 hours without power saver and 3 hours with power saver and compare kw/h with a meter same model form company electric.

    so here can see true power saver and scam power saver.

    we not recommended buy power saver from shenzhen jumbo power saver is are 100% scam
    Also noted Alibaba aliexpress made in china protect gold suppliers because every year gold suppliers paid $6000 to $7000 for show product to is website, problem bad verification form alibaba aliexpress i show to 1 video to youtube is are bad veryfication you can see to the disclainer alibaba the company promose. just promise for get gold supplier status and scam to international.

      To all who may see it:

      The report from Mr.Sun on Oct.13.2016 isn’t correct and he doesn’t respect the truth.

      As he said that only Kvar capacitor with PF controller can save. I don’t think that he knows much about the real saving technology.

      If as he said, Jumbo power saver is scam. Then how to prove that his words is true ? Jumbo saver is PF correction device with Kvar capacitors and we have lots of saving examples to show customers. How can Mr.Sun that there is saving by other Kvar savers while there is no saving by Jumbo? If he really know about this tech, then he shouldn’t say it like this.

      In fact, His aim isn’t helping buyers to make right decision. His aim here is going to use blacklist to say Jumbo bad words. He wanted Jumbo to die and this is his destination.

      Mr. Sun,our former customer who doesn’t respect the business rules and he is not honest person.

      I swear in the name of the God here, Jumbo didn’t cheat Mr.Sun. Dare Mr.Sun swear in the name of God that he is really honest on this matter ?

      We lost business due to his bad behavior and we have all proof to show what kind of of Person he is. He is using all blacklist and links to show Jumbo bad words as revenge.

      If any customer want to know the truth, you are welcome to contact. [email protected] for more info.

      If any supplier see this information, I don’t suggest you to do business with Mr.Sun.

      If you really want to be headache, just try to do business with him. I do believe that he got lots of bad buying history in China. And you will be 100% unhappy.

      Even Alibaba has no words about him. He said that alibaba is scam and didn’t protect his benefit. In fact, for the whole process, alibaba is protecting the benefit of customers. We have all proof to show it.However, during the communication with alibaba, his attitude and words didn’t stand right,so,he failed. And now he can only say bad words about Jumbo as revenge.

      He retuned the goods and we refunded him 100% money. Still now he tell fake story online that he lost 1220USD.

      I want all to ssay,if you buy some products from China and you damaged the products during wrong operation and wrong installation, then you ask the supplier to refund. Will the supplier do it ? Maybe 99% won’t.

      However, we respect the benefit of others and we refunded all. And we don’t want to be headache with Mr.Sun. However, Mr.Sun still say online that he lost 1220USd and even ask me to give free H20 saver for compensation and also he ask Jumbo to give him shipping cost from Cambodia to China. Is it fair ?

      He said that Jumbo has defect on the products. Yes,Jumbo isn’t 100% perfect and we still have a long way to improve the quality and everything and now we are doing that to make ourself better and better.Besides, I have the confident to say that we are the best power saver manufacturer in China. Maybe customers don’t believe what I say, then you are welcome to compare any other brand from China with Jumbo and tell us the disadvantages. Most welcome.

      We work with customers honestly, not like Mr.Sun, can only say bad words and use knife on the back. This kind of person I dare to say, if he didn’t get brain problem, then must be a person without good temper and personality. If he is good person, then he will not use blacklist to say words which isn’t true. His negative can’t help any customer , only the best way for him to revenge for his so called lost. You will see may fake reports from many webs when you search Jumbo power saver. All are from Mr.Sun or Mr.Tee Sama. Maybe they are same person.

      I would like to make this information open, for the reason that Jumbo never worry about bad words from customers. But we respect the customers who give us real advices. If the person who like Mr.Sun, in the aim for revenge only. Then,we have enough confidence to say big NO.

      Thanks for your attention and best wishes to all who may see.

        I believe your comments here are nothing more than a smear campaign of Mr Sun for expression of his opinions only.
        If he caused your company damages, sue him for your loss. If your product lost sales due to his words, prove it.
        The sales of “Jumbo” should speak for itself through the ratings of others who bought and are using the product. Every product speaks for itself. If it’s an amazing product, your sales should not have been bothered by the bad opinion of what ONE customer says, it should be reflected in your profits from the consumers who bought and believe in your products.
        All you did here was try to discredit Mr Sun because his words and due to your business dealings not working out. You resolved your issues with him, move on.
        Bashing an unhappy customer who has opinions about your business or it’s practices is not something a professional representative of a thriving company would do.
        Those claims of business loss would be handled by your attorney in a law suit, NOT babbling on the internet where people are trying to find out REAL REPUTABLE information to make informed decisions.
        Your words reflect badly on your company and it’s reputation. Basically a waste of space.
        With that being said, I wish you luck in your future endeavors of your business and your products.

    This statement – to remove CARBON from the CIRCUIT – is misleading. No electrical engineer, textbook etc do not use word CARBON in such semantic mood. At least I am not able to find out such slang usage (to remove carbon from electrical circuits) inside electrical engineer community or any other inner circle.

    Hi there, while true, at the same time using a high quality power meter, I noted a 15 Watt savings on a 70 Watt florescent light fitting. It was running at 100 Watt there was no cap across the supply so I added one and it dropped by 15 Watt. There was an instant savings and this is the way to do it. A cap on the far end of an unloaded line can cause the voltage to increase and is considered dangerous. Also just adding capacitors can result in harmonic amplification of the voltage, increased voltage distortion. Ask any car audio nut, they know that often adding a supply cap can make more noise or hum in the audio rather than removing the noise, a result of a greater voltage drop across the supply lines. You can always save energy by reducing the resistance of the supply cable. We all accept a 5% volt drop on a supply cable but fail to remember that it implies a 5% power loss!

      Science is non-negotiable. Your device either follows the rules or doesn’t. Since many have negated your device on electrical principles, it’s not possible for the device to work in your home. If you are telling the truth, then you are saving money monthly because you are probably unconsciously turning off more devices around your home when not using them, such as lights, stereo equipment, televisions, etc. I’m sorry but just wishing something to work that opposes electric principles is only that – wishful thinking.

      I think that perhaps you should do a bit more education and less anecdotal evidence. I order to sell your device to homeowners, you have to be naive and misinformed, or devious and unscrupulous. I hope it’s the former, not the latter. And before the word gets out to the masses, you should find another source of income.

    Fixed capacitance type PFC only works when it is of right capacitance value to a given motor load. Since the household has different motor loads and switched at different times, this may not work all the time. For household, automatic power factor correction should be the way to go.

    Any reduction in current will reduce the speed at which the disc on the meter rotates, hence reducing the monthly readings. More info right here

    Thanks for the information. It did bring long forgotten concept of my automation and control course….It was a nice review! People will more end more dream of saving as price of energy rise up!

    I have 2-50 Amp power saver 1200, 1 at my home and the other in my office. I installed them in Nov 2014. For November my bill fell from $112.00 Average to below $78, the next bill was under $86 and my last bill ie for Jan 2015 is $68.25, so for me, my US made Power saver saves over 30%.

    Re: my office in Nov I paid $57.43, Dec $38.17 and Jan $29.88. In Dec I saved 34% and in Jan 48% or an additional 22%. so maybe, you need to by your from the USA!

    You write: “The systems also automatically remove carbon from the circuit”

    Remove carbon, the element ‘C’ (atomic number 6), is that what you say? I have never seen any instrument removing ‘carbon’ or anything tangible from an electric circuit. Electric energy is converted in other types of energy, yes, but carbon?

    So what do you mean?

      He meant it in a descriptive sense, carbon build up in an exhaust creates poor flow, he used it as similarity to an electrical network flow.

      The guy doesn’t know what he’s talking about. Engineer my b—. These power saving devices don’t work, it’s just a scam. It doesn’t remove carbon (which has nothing to do with electricity), it doesn’t do anything.

    Dear Mr. Parmar,

    I just find your article very useful. You have given a perfect explanation of the power saver use for domestic consumer. But I want to ask you a question about my situation. First of all, I give you a little introduction of the problem. I have on the roof of my house a solar plant for domestic production of energy. In the max period of production – in summer – in the most productive hours of the day – i.e. from 12:00 a.m. to 02:00 p.m. – the inverter of solar plant goes down in error for security because it overcomes the limit voltage permitted for the immissions of energy into the distribution line. The limit is reached because my house is at the end of household distribution line and the cables have a less diameter because very old. In every case, the household told me that from their measurements the parameters all right. Anyway the problem persist: the distribution line couldn’t take all the energy produced.
    The question is: could the use of a power saver reduce the problem? Theoretically, it modulates the energy signal like a filter, so the energy that will be inmitted into the elettric line would be all taken. What do you think about that?

    Hello, I purchased energy saving devices from a small manufacturer. They actually said I needed two to cover my entire home. One to be plugged in for the odd numbered circuits and one to be plugged in on the even numbered circuits (in the breaker box). I did experience a savings of about 7 or 8 % on average on my electric bill. However, I also seemed to experience some problems with my electricity, such as furnace blower refusing to run properly, refrigerator problems, etc. so I am wondering if the stored power can cause problems. I no longer use the devices.

    Thank you for the self explanatory article. Saved my money just now by not buying it.
    Better off invest in uprating household size of the wire from #14 to #10
    Save some money on decreasing resistance of the wires, in 10 years will get mine 3-5% of energy bill back (after paying for the new wires) it is better then saving less then 1% with this useless device.
    Thanks again.

    What is the size of capacitor should be used for 1HP motor, 2HP motor and 500W refrigerator for power saver purpose? For 230V 50Hz grid. Thanks in advanced.

    Appreciate this article .We require 3 Phase Energy Savers.The products should reduce reactive inductance and increase the power factor. electronic product is preferred.

    is there any product like this if so what could be the ideal savings and approx cost

    Most of those selling household type energy saving devices that plug into an outlet ask the consumer to wait a few months to observe their “savings” and base it on the actual bill. In reality, if the device can really save on electricity consumption, it can be instantaneously measured by using a standard watt or kilowatt meter. The kilowatt-hour is just a measure of consumption after one hour. Some use a clamp on ammeter to prove the energy savings. What they were showing is volt-amperes not watts which is volt-ampere multiplied by the power factor. The consumer pays for the watt-hour (or kilowat-hour), not volt-ampere-hour. Perhaps the scammer is banking that by probability half of the buyers will experience some reduction in billing although half will experience an increase in their bill, although the gadget does not have anything to do with the reduction/increase in billing. Perhaps the tariff got lower of there are fewer days in a period covered. Anyway the one half of the consumers who found their bill reduced will be happy and attribute the reduction to the “energy-saving” gadget. The other half may just keep quiet or be shy in filing a complaint.

    Excellent article.
    C’est bien expliqué et on comprend que les arguments de vente des fabricants sont une arnaque puisque la facture d’électricité en résidentiel est basée sur les kWatt. Peu importe le facteur de puissance que nous avons à la maison.
    Merci pour vos explications.

    hello mr. jigu parmar. I like your article. and I am agree with you. but I had seen and observed in 3 phase load system, that if I connect a 3 phase capacitor across the load then current goes down. But I also observed that unit consumption of load (kwh) per day also reduced.
    I just need to know ., why did it happen.?

    the capacitor for reactive compensation comes with price . more time you expose these capacitors to grid system, more is the chance of capacitor dying. And if we consider a harmonic distortion in supply , the capacitor life drastically comes down as the capacitor draws more current than its intended. i still feel this power saving should be prevented being sold unless it is tested and the values are tabulated and the performance is tested for at least a year.

    Does capacitors affect the operation of a disc type watt hour meter? I have seen some demonstrations wherein the rotation of the disc slows down everytime the device is turned on.
