I'm going to Europe in June, and needing to get a small extension cord/surge protector/power strip device with some USB outlets (the 2.1 amp ones to charge anything) 50/60 Hz, 120/240 VAC that I can use to plug all my devices into so that I just need the single adapter plug for the wall socket. I want a small cord for it (~ 3 feet or so), so that it'll reach a short distance so I don't have to have issues with it being usable if a short distance away from the wall. Ideally, I can plug my USB devices directly into the USB sockets, and other things, like a MacBook charger would plug into regular 3-prong sockets on it (probably would want 3-4 of those. Any suggestions for this? I've been looking around on Amazon, but, it's pretty confusing with the hundreds of devices they have. Thanks!
