What do you get when you cross an Energizer EnergiToGo portable charger with a hand crank? If you answered the Yogen Charger for Life, you'd be correct. Easy Energy is demoing the battery-less battery charger, and sadly for us, it didn't work exactly as advertised. While the other demo models seemed to be working without a hitch, when we started pulling the rip cord, instead of getting a lightning bolt indicating that our BlackBerry Tour was charging, we got a reboot. It's probably an isolated incident, as every other device we tried worked, but we'd be doing you, our trusted reader, a disservice if we didn't let you know.
