I just got a new Nokia mobile phone and it came with a switchmode mains charger plugpack as many of them do these days, but this one has an Energy Star label saying this adapter was energy star compliant for reduced consumption. This is the first time I've seen this on any plugpack, so I thought I'd test it out.
I got 0.12W on my energy meter with no phone connected. Compare that with 0.55W for my old Nokia transformer plugpack, and 0.55W for a (presumably non-energy star compliant) Motorola switchmode plugpack.
That's a big saving, especially when you multiply it by a few tens of millions of phones. Very nice indeed.
Dave.
