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.

The whole lot is dubious at best. Down right misleading would be closer
to the point.
Always a problem when you have non technocal maketing droids write
greenwash. Even if you ignore the 4kW phone charger, the advice to
landfill a working freezer on the *assumption* is is drastically less
efficent than your current one risky at best, and that is before you
look at the life cycle energy of disposing of the old one and producing
and supplying a new one.

Its part of the 'good lie' which has become more common as of late. It
doesnt matter if the information they tell you is misleading, or just plain
incorrect, if it is in a good cause (as judged by them) then it is ok.

Many gullible people remember this crap. My TV only uses 0.8 of a watt on
standby (not that I leave it on standby often). I am getting fed up of the
greenies making everyone feel guilty about everything - there are bigger
issues - like the pollution made in China by their dirty power stations and
processes (producing goods for us that are then shipped half way around the
world); destruction of rainforests, etc.
People are only too happy to point their finger and tut everytime a
politician of member of royal family use a car or aeroplane - but miss
issues that are statistically more significant.

Maybe the publicity dept got the decimal point in the wrong place
Should it not have been 100 x 10 to the power of -3 or 100mW, but then
the publicity dept thought we are a generating company and do not deal
in such small numbers, and dropped the minus sign and made it into
100kW.
Or maybe the typist thought the engineers notes had just got a pencil
mark on it, and did not transfer the minus sign ???
It does make you wonder how many eyes (on multi thousand pay packets)
read that bit of paper before being published.

It may have been extrapolated to their entire customer base,
assuming each account had a similar device.

I have one of those energy monitors from Maplin, my mobile phone
chargers use nothing when not plugged into the phone.

They will use a small amount. I expect its too low to show on the monitor.

Is that the £26.99 one on the Maplin website?. How accurate is it at low
current?

What make and model is that? Is the 0.8W figure your own measured value, or
a manufacturer figure?

I don't know about his TV but Sony say that my LCD 23" uses 0.7W on
standby - that seems very low and makes you inclined to question all of the
figures being bandied around by the Government!

There is now a standard governing stand-by.

It is worth noting that many modern phone chargers are switched mode
power supplies. Many of these will in effect turn off when there is no
load.
