You know those hand-crank flashlights that seemed to be all the gift-giving rage this past holiday season? Surprisingly, these hand-cranks can be modded to charge a cellphone and it seems to be really easy to do so. Open up the flashlight casing, cut the cord on an old cellphone charger and solder the wires into the flashlight. It is an easy, good and environmental friendly way to get some extra juice out of the phone in emergency situations. Be noted that the erratic charging may not be the best for the cellphone, though. –Travis Hudson
