The Hand Crank Emergency Cell Phone Charger
This is the charger that converts one minute of hand cranking into 30-second bursts of emergency power for a connected cell phone. Ideal for placing an essential call or sending a text when a cell phone’s battery is nearly depleted, its fluid operation provides the same crank-to-power efficiency as dynamos used in larger emergency radios. Its integrated 2,000 mAH lithium-ion battery recharges fully from a 2 1/2-hour USB connection to a computer or a USB AC adapter using the included cable, providing ample energy to fully charge most smartphones (requires smartphone charging cable).

Wow..how many times do I have to churn that crank for it to recharge full capacity. Gotta love that idea though. Exercise and electricity all in one.
