The K-Tor Power Box is a pedal generator, which means the electricity you generate by pedaling with your feet or arms can be used to charge any portable device that uses a rechargeable battery.
It’s not a pretty thing, but the thing is that it generates free electricity out of nothing except the sweat of your brow.
You get to charge your devices while you do some cardio and shed a few pounds. You use it like a stationary exercise bicycle, and the electricity can be used directly to charge multiple devices such as mobile and smart phones and tablets, or stored in a battery and used later as required through an inverter. It’s quite portable and much smaller and lighter as compared to an exercise bike..
