After surfacing on April Fools' Day, ThinkGeek made its gadget-charging Flux Capacitor into an actual product. Sporting all of the details of the full-sized power plant, this diminutive option leverages your car's cigarette lighter to juice up a pair of devices via two USB ports. Of course, those 1.21 gigawatts of power are reduced to 2.1 amps, and there's an on/off switch for the $25 time-traveling accessory's lights. And yes, they actually pulse just like you hoped. Of course, if you're looking to splurge for the real deal, you'll need to shell out a bit more dough.
