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.

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