The Crankerator — Human-Powered Battery Backup

Photojojo’s Crankerator is a backup battery pack with a twist. Or rather, with a spin. You can charge it via boring old wall outlets, but when the juice finally runs low, you can reanimate it with a few twists of the crank-arm on the side.

Where by "few" I mean "at least a minute of furious cranking." Still, if your iPhone is totally dead, this is a lot better than nothing, and it’s more portable than a solar panel.

Between this and my Hario hand-cranked burr-grinder for coffee, I’m going to come back from camp with bigger biceps than when I left. $60.

2000 mAH lithium battery and emergency generator

Stores energy through crank-power or plugging into the wall

Charges any device that’ll charge via USB cable (phones, toy cameras, flip cams)

Fully charged Crankerator can fully charge a phone

A pocket-sized 1 x 2.2 x 5 inches
