Person Man is right... so long as you have a plug adapter you should be good to go in any country that does 110-240. HOWEVER... if it's a slightly underdeveloped country, the reason you might want to rethink leaving it plugged in for periods of time is because of power fluctuations. The electricity in third world countries are pretty dirty, and fluctuate like crazy. If that's the case, you need to get a surge protector, and while you're at it, maybe an APC back up battery so that you have constant juice flowing through.... but only if you're going to a third world nation.
