Brought to you by the license-happy folks at the Back to the Future brand, this flux capacitor really works — at phone charging, that is, but not so much at time travel. Well, not unless you count inching forward slowly in dead-stop traffic. The capacitor has two USB ports so you can charge any USB device, works with your DeLorean DMC-12 cigarette-lighter and comes with some extra dork-friendly features such as on/off capacitor lights. Measures 2.5″ x 3″ x 1″ and is yours for $40 from ThinkGeek.
