hot recharger help in scotland

Hello,
I am currently out photographing in Scotland and plugged my powerbook into the outlet to recharge.
Everything seems to work and charge fine, but it seems that my charger (the plug part) gets really hot and I'm worried about it getting super hot and blowing up or something....
is this normal?
The plus is pretty darn hot.

Hi friend,
I live in scotland, and in here for some strange reason my powerbook overheats when plugged.

Don't worry it won't explode!
