Oh god, I thought you meant a Transformer (sorry, had to):

You could ask Final-Fan, I believe he's been there. He might tell you about it. In here, they say that the Japanese 360 uses 220v and the American one uses 120v. If I understand correctly, it means their plug should deliver more than enough power for yours if theirs needs more in the first place anyway. I'm a newb, so don't take what I said in consideration.
Random game thought :
Why is Bionic Commando Rearmed 2 getting so much hate? We finally get a real game and they're not even satisfied... I'm starting to hate the gaming community so f****** much...
