The Yogen is a little power generator that uses your pulling action to generate electricity. The break-through in manpowered charging performance of the YoGen® accomplish by pulling the included cord and transfers the linear kinetic energy generated by the pull cord to the flywheel-enhanced rotary motion of the alternator itself. So the next time you travel some where don’t bring extra battery, bring one of this and you will have unlimited power.
