We were pretty intrigued by the Yogen manual charger concept we saw earlier. While the production unit we saw today is markedly different - it doesn't disappoint. Instead of charging gadgets with a pedal, users now pull a chord.
Charging devices while pulling the string takes just as long as charging them via wall outlet so it won't replace plugging in, but in a pinch the compact device could be a life saver. There is super-low resistance in the chord so continuously pulling the string to charge isn't much of a chore (just tedious). The device is available now directly from Yogen for $US39.99.
