I carry this one as it works for domestic and international travel. If international, just slap an adapter on it and go. If domestic, it's ready to go. The outlets on it will accept either plug type, so if I have to unplug a lamp or something to get an outlet to plug it in, I can plug it back into the strip. Some may want one with more outlets (they're available on Amazon) but with the built in USB ports, I find that the only thing I usually plug in is my laptop, and I charge my electronics off the laptop or the USB ports. This one is small enough to pack without taking up any significant space.
