Ben Heck has been modding things and making things for a long time. The geek landed his own show doing what he does best not long ago and has made all sorts of cool gear since then. On the latest episode of the show, Heck made a cool charger that lets you power your Android photo on the go by winding a crank.
The kinetic charger uses a LED wind up flashlight and a micro USB charger that can be purchased over the counter. Heck puts some mod juju on it to combine the two parts into a crank powered charger.
The idea is that you can twist the handle to get juice for your Android smartphone on the road. It will work with any micro USB charging phone though. I wonder how much power the thing generates.
