ThinkGeek Star Wars R2-D2 USB Car Charger - Rotating Head, Light Up Eye, 2 x USB Ports, Plugs Into Cigarette Lighter Adapter

NO NEED TO GO TO TOSCHE STATION. While we don't yet have the technology in this quadrant of the galaxy for fully-automated repair droids like the R2 units from Star Wars, we can get a portion of the R2's versatility into something small enough to sit in your vehicle's cup holder. You see, it makes R2-D2 whistle sadly when he sees a device that's run out of power. Make him bloop and bleep happily again by letting him use your vehicle's power to recharge your devices. With him plugged into your 12V vehicle power adapter (cigarette lighter), you can get 2.1 Amps through each of his USB charging ports, which is enough to charge two tablets or smartphones or, well, pretty much anything that charges via USB.
