Also, UK (that run on 220V) power adapters tend to offer better efficiency in the AC->DC conversion by about 5-10%. You see it all the time on desktop PSUs, so I can think of no reason why the same isn't true here...possible the 90W part is either not delivering 90W for us, or it's delivering slight more than 90W for him.
