Wind-Up Battery By Qian Jiang

When talking about saving energy, we have heard a lot about using solar powered gadgets to help. However, the wind-up battery by Qian Jiang is a different approach. Though cranking is not new already but the concept of using it to re-charge a battery is something new to the market. The wind up battery is a battery cell that has a spring handle that can be used in cranking to re-charge the battery. Cranking it for 20 minutes will charge the battery in full. The indicator light will turn to red when its full and green when low powered or empty. Aside from cranking, the wind-up battery can also be recharged via the conventional battery charger.
