The Crank Up Battery by Qian Jiang is an environment-friendly re-chargeable battery. When the batteries run out of power, you only need to wind them up with the hand-cracks and they will then get fully charged in 20 minutes. There is also a tiny light next to the hand-crack, which emits yellow light to remind you to charge the battery.
