A mobile battery that could be charged by spinning it around your fingers .
The concept design promises quick charging in places where a wall socket is not available to charge your mobile phone. Based on the specs presented, it requires you to rotate the device approximately 130 times to get enough power to make a call for about 2 minutes.
At standby, the juice generated from revolving the battery could last for around 25 minutes.
