Pro Power Saver Power Saver Electricity Saving Device Save Electricity Electricity Saving Box Household Office Market Device Electric US Plug 90V-250V 30KW 4 Pack, Green

It has to be said that it can indeed save electricity. In July, my electricity bill equaled about $62. In August, as of today, my electricity bill is about $33. Its casing looks sturdy and there is no need to worry about security. Simple operation, just plug it into a power outlet, this is a good product and I would recommend it to my friends and family.

All hype doesn’t work at all. My question to Amazon is why you allow this product on your site. In my opinion a very shoddy business decision.

After ordering and installing these power savers < I did not change any usage of my electricity as it was more than a half month since my previous electric bill. In that very short time of usage, I noticed a substantial reduction in my most recent bill, while using the same equipment operation IE: pool pump, air conditioning etc. I hope that my next bill is much lower. Any savings on electricity is a plus. !

No noticable benefit

Haven’t been a major change in effectiveness will come back and let you know. Made a $25 difference in the bill will keep checking

I am a certified E-tech. I use to work for the power company. I know about how the voltage shifts as it relates to current. Motors are inductors and they shirt the current to lag the voltage. That is how the meters work. Power lines act like inductors too. The power companies place Capacitors inline to correct for the phase shifting to save Their transmissions down the line. If you can shift your phase back so that the voltage & current are InPhase, then you are in for a gain on your power usage! I have one of these, and you should have two, on one leg of the 220v service and so far i have saved money from last week. As noted by my power provider. The trick is to find the two legs of your 220v service and place one on each leg. tip: Some house service panels have one leg on one half of the house & the other leg on the other half of the house. Find those breakers feeding those outlets as close to the breaker panel as you can and plug them in there to catch the in&out of the power. OR! They are rated for 220v. . .right? Install a 220v outlet next to your service panel & plug one in. Hint! The pins do not fit.

I can see a difference

They don't work

This is just a scam, do not waste your money. My usage is more since plugging 4 of these in. They should be banned from selling on Amazon.
