All iPod chargers are universal 100-250v 50-60blah blah blah.. so all you really need is the plug changer (hard to find there, easy here) OR a car charger would suffice, YOU'll have a blast!

I read an interesting tip in Budget Travel recently: Instead of using tiny padlocks on your backpack or on luggage, connect your zippers with key rings. They're just as much of a pain to get off and aren't a flag to thieves.
I love it! Cheap, easy, giddyup!
