In the UK domestic users are charged for WATTS and not VA, thus power- factor correction will not reduce the electricity bill. I have to say I am sceptical that this device will be of any benefit at all when conn- ected to a domestic appliance in the UK. If you are charged for electricity in VA, then the thing may well help in the manner mentioned above. >I can't speak for your device or its claims whoever, but this sounds like >what it is trying to accomplish.
