According to FAQs page on their website, the device uses rare earth magnets that provide power to the U Plug Generator, working in groups to initiate and maintain constant, continuous energy. The magnets rotate in a simplified planetary gear system with multiple shafts that have our magnets in them. Each magnet can pick up over 2500 pounds each. There are several magnets per shaft, and when they are in the proper position they begin to spin. This will cause a push pull type of effect that has worked quite well for over 2 1/2 years. Then they surround the unit with the field coils to generate the power. Those items weigh about 7 pounds (about 3.2 kilos for the metrically inclined), then there is the circuit boards, housing, outlet, and that brings those items up to about 10 pounds. The most weight is all the copper for the windings to produce the power.

I think to better understand how it works, you have to look at what the company has patented to see if they've discovered anything new.

They claim that each individual magnet is capable of lifting over 2500 pounds of weight.

Here's a link to the strongest magnet that K&J Magnetics sells:

https://www.kjmagnetics.com/magnetsummary.asp

It has a pull force slightly less than half of that claimed by "U-Plug" and costs over a thousand dollars. (They are cheaper in quantity; if you order 10 or more they are "only" a bit over 800 dollars each.) And it weighs about 8 1/2 pounds.

Note especially this: "This magnet is not a toy and should only be handled by professionals. We
recommend always having at least one other person help you handle this
massive block. We use a team of at least three."

So how many of those monster "2500 pound pull" magnets are inside a U-Plug source? And where did they come from and how are they mounted? Inquiring minds want to know.

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:

    Type of electrical load of house,
    Basic power terminology (KW, KVA, KVAR).
    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.

    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.
    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.
    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.

My first reaction is that such a device would likely consume power, and would be a scam, as discussed here.

I think the idea is this.

Your electricity delivered to your house actually varies from about 110V to 126V which may be dependent on where your house is, and can also vary somewhat during the day.

You used to be able to buy a resistor to use with incandescent lights, say to convert a 100W light bulb to 60W output. 

This device would do the same thing.  Instead of just passing through the 126V, it drops the power down to 110V, and thus provide you with about 10% less voltage, but still within the acceptable range for household appliances.

What happens next depends on the appliance.

Your lightbulbs in the house would all dim slightly, but perhaps not enough to be noticeable. 
Your toaster would run cooler, so you would likely compensate by toasting your toast longer.
Your hair dryer would also be slightly cooler, and would also require slightly more time to dry the hair.

Motor driven devices such as the refrigerator would likely use similar wattage and not show a savings.

Your TV and computer with regulated power will likely be unaffected.

A small benefit shows up, but in the Real World, it is likely that this benefit goes away.
When you like a flower, you just pluck it out.
But when you love a flower, you water it daily.
The one who understands this, understands life.

- That's the difference between I like you and I love you.

That diagram might just be a fake. Capacitors simply store and/or smooth out electricity and won't save you money for using.

1) If capacitors can smooth out electricity, then would less electricity convert into heat energy (saving energy)during the power spikes?

2) Referring to following articles, would capacitors only keep your electric appliances from frying if a power surge occurs? It would not save electricity, because the extra voltage would be channeled to the outlet's grounding wire.  Would it be correct?

Do you have any suggestions on whether 1 or 2 is correct concept about capacity working on electricity during power spikes?
Thanks, to everyone very much for any suggestions :>

"If more voltage is introduced than an electrical appliance is designed to handle, this is called a power surge or transient voltage. Any such voltage increase that lasts at least three nanoseconds is considered a surge. If the increase is only present for one or two nanosecond, that's called a power spike. Just like if having much more water in a hose than it can handle, having too strong a power surge can damage your electric appliance. The greater voltage that runs along the electric wires causes great heat that can burn up the wire. Even if the wire doesn't get burned up in a single power surge, the surge can damage the wire. So repeated occurrences of power surges can accumulate enough damage to the wires that the appliance eventually burns out.

The good news is that you can buy surge protectors to keep your electric appliances from frying if a power surge occurs. These power strips do more than just let you increase the number of outlets by plugging them into a single wall outlet. Whether the increased voltage can be classified as a surge or a spike, the surge protector uses its metal oxide varistor (MOV) to channel the extra voltage to the outlet's grounding wire. The MOV has three parts: a piece of metal oxide, and two semiconductors. The metal oxide is connected to each of the semiconductors. One semiconductor is connected to the grounding wire and the other one is connected to the power line. The MOV does nothing if the voltage is correct, but it is able to divert only the extra voltage during a power surge to the grounding line, making sure that the right voltage is still flowing to the appliance. This design ensures that your appliance can still operate, even during a power surge or spike."
