How it works is that the USB charger comes with a swing out rotating power tab which means all you'd have to do is unplug whatever is being used at the moment, put it through the rotating power tab on the FlipIt! USB Charger, plug it back in and you're good to go, as shown in the photo above. It's also small and compact and durable so you will be able to take it with you wherever you go and it should work with power plugs of any US 100-240V device and will provide enough juice for devices that require USB power up to 1000mA. If you're looking to get your hands on this handy little device it will set you back only $13.99, just head on down to ThinkGeek's website.
