Bought one of these for a trip overseas three years ago, and it immediately went to the top of my Travel Necessities list. Since it includes a US plug, it goes with me to conventions, etc., since there are NEVER enough outlets in the hotel room; having four built-in USB ports is really handy, since we can use the faster ports for our phones and the slower ones to charge things like backup batteries, activity trackers, etc. Highly recommended.
