Recharge your battery – just swing it

New concept of technology has now been brought by Song Teaho & Hyejin Lee. This new technology allows you to recharge you mobile device battery using your finger only. Just swing the device and the generator inside will also spin up. The spinning action from the generator will result the electricity power to recharge the device.

It is very smart concept and need to be built than we bring the charger everywhere. You can see the demo images below to explain how it works. With spinning for 130 times, it will light your phone on for 25 minutes standby or 2 minute talking, enough time to say good bye before your phone is off.
