Ultra Cool Battery Concept – Wind-up Battery

Wind Up Battery

Wind Up Battery

The Wind Up Battery is a rechargeable battery with a little pop-out hand-crank to power up using some good ol’ fashioned elbow grease. I’d probably looks like an idiot using it, but better than suffering without a AA.

Designed by Qian Jiang, the concept is actually rather brilliant since it wouldn’t require an additional gadget to recharge your batteries and depending on how many recharges it would allow for, it might be a rather good deal too. Since this battery is still a concept, I’m a bit skeptical about the claim that it could be fully charged in 20 minutes, but that would be fast enough for most of us. [Yanko Design]
