There are some power saver devices shown in TV advertisements that they can save electricity bills.
But, does they really cut down electricity bills as advertised? Does they really cut down bills by 50%?
No.
How they can save bills and how much ?
They merges the cosine spikes in electrical waveform resulting in less spike height, so they can save bills a bit. They are simply plugged into wall plug and they do that by help of a capacitor. There are some indicator lights in the device which does nothing but just shows power ok. It can save power around 10% actually.
Which appliances power consumption it can make low?
Only inductive loads produce cosine waves and it can be useful in cases of electric heaters, air conditioners, electrical motors, induction cookers, etc.
How to make it?
To make power saver circuit, you just need a capacitor of 5-10µF of 220V or 440V according to your area grid voltage is 110V or 220V.
For this, I’d recommend buying the oil based capacitors that are used in ceiling fans. They are just 2.5µF, so you need to parallel 2 to 4 capacitors. After that, just connect them into plug and see it works.
You can also use any other oil filled capasitors, like used in water pumps, to make power saver circuit.
Just choose the one with correct voltage rating and make sure they're non-polar capacitors.
Bottomline: If you run AC, refrigerator, electric water pump, etc then connect a capacitor at the same plug to save some bill.

Can i have its demo video
When I connect 4X2.25uf how much amps barring the unit and what is the home appliances conneting this unit
Thank you engr for sharing your knowledge. May God Almighty continue to enrich your knowledge. Can someone connect these capacitors across inverter output due to some inductive load that drain the battery faster...
When I connected 4 X 2.25 uf capacitors how much load carting this unit. What is the home appliances can I used
Nonsense! Residences aren't subject to power factor billing. So this won't reduce energy bill. And your technical explanation is also nonsense.
i wan make power saver boz my bill coming tooo much every month im totaly fedup. from bill
good day. can you make a circuit diagram of a power saver intended for a room airconditioner and a refregerator respectively. i try to use the example but it will not work on the a/c and in the ref. please publish it . thank you very much and more power.
give details of ckt on how to connect the four parallel capacitor on my aircondition system
Boss capacitor used only on motors? how come reduce the electric bill?
How to connect this capacitor if you load output voltage is 220 volts. Give me some idea to connect this capacitor to my air-conditioned units.
This IS bullshit. This circuit will not save on your power bill.
