Can I take my American iPod to England and (with nothing but an an adaptor to correctly plug into a British socket) plug it into the wall for recharging? Will it accept UK power? Will it blow up? I want to listen to music while I'm there, but I don't want to break an expensive piece of equipment. I tried Google and Apple.com, but I couldn't find anything about this.
