Default Southern Electric say each mobile phone charger uses 100kWhours a DAY!



Have a look - how can they get it so wrong by a magnitude of.....???

My chargers both say they use about 21mA max.

Also, point 3 seems a little dubious too - AFAIK, the only things that use
any significant power on standby are digiboxes.
Surely the rest just take enough to keep the coil energised? My TV and video
both use < 4 watts on standby.
