Ben Heck demonstrates hand-crank phone charger
In the video below, Heckendorn (aka Ben Heck) demonstrates his hand-crank powered charger on his HTC EVO 4G. He stripped down the crank from a rechargeable flashlight, and then retooled it to send 5 volts of power through a mini-USB cable.
While the charger was built for Heckendorn's EVO 4G, the model could be used on most any smartphone. Not only will you be making a 'green' effort, but you might get a workout in the process. Use proper caution: if you don't know what you're doing, just use your wall charger.
Heckendorn is the author of Benheck.com, and is the creator of consumer accessories like the AudioFX 5+1 Headset, and the one-handed Access Controller for the PS2, XBOX 360, and PC.

Well, that's just fine - but it is certainly re-inventing the wheel. There are several hand-cranked options out there that will take a USB cable connection and charge your phone. I've got one at home (can't remember brand) that has a flashlight in it, and a hand crank, has a USB port for charging, and can be charged from AC. I carry it when we travel because it also includes the flashlight in case a fire alarm goes off in the hotel, and because it serves as an emergency battery (when charged, without even hand cranking) for whatever device I plug into it. It's about the size of two decks of cards, stacked. There are other, smaller options out there as well. There are a bunch of these devices available. The smart choice is one with a USB port so you aren't left looking for charging tips or having to ditch it when you change phones.
