My sons are heading for Europe when during PSU's Spring Break, and plan on using their IPhones over there. Not having traveled in Europe, I was wondering if someone on the all knowing Board can tell me whether they will need some kind of adapter for their IPhone chargers. And if so, whether a specific kind of adapter particular to an IPhone is needed, and where I might look for one. I have heard that the electrical voltage over there is somewhat different. Any information would be appreciated.
