Plan on getting and using a power adapter, for wherever your destination happens to be. Make sure to have enough outlets for the equipment you’ll need to charge. If you go to Japan, their power plugs are the same as the U.S. but it’s 50 Hz instead of 60Hz ( at least on northern Honshu anyway). This makes U.S. clocks run slow and may end up damaging some circuits. Here’s a link I found from a dogpile search: http://www.kropla.com/electric2.htm
