- 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.
