20mW is exactly what a mains-powered device should be consuming on stand-by, and nothing more.
It is particularly good because, as I remember, the most stringent self-imposed phone charger industry stand-by limit is 100mW – although I cannot remember from whence I obtained this ‘fact’.
The Yorkshire firm also does a smart mains multi-socket that allows several mains loads to be turned off at once – in this case by infra-red using an existing TV or DVD remote control.
For this it gets eight out of ten on the Alice Scale as its own stand-by power is 190mW – very very good, but not 20mW.
I looked at smart multi-sockets last year – the type where switching off one main load causes the socket to switch off all the other loads – and as I remember the best was rubbish – close to 1W – and others were far worse.
By the way, Energy Saving International got a grant of £2,500 from CO2Sense Yorkshire, a business support and market development programme funded by Yorkshire Forward and the European Regional Development Fund
