Re: can i use my galaxy tab pro smt320 while vacationing in England or whilst on an airplane
Welcome to Android Central! Are you asking if you have to worry about the different voltage in the UK compared to the US? If so, then don't worry--all chargers that come with devices these days should be compatible with both 110V and 220V. To be sure, just look at the charger and make sure it says 110-220V. The only thing you need is an adapter to fit the UK sockets.
Some airlines have electrical outlets (either standard sockets or USB ports) in front of or under the passenger seats, so ask the flight attendant when you board. Otherwise, get a good external power pack--you can get a decent-sized one for about $10.
