Cheers To Finger Power!

Mind you, this is not a “Green” concept and neither does it claim to be “Eco Friendly”. It’s just a helpful solution for a tricky situation. The situation being: you running out of juice on your mobile phone. So what do you do? Remove the battery from the back of the phone; give it a few good turns around your index finger and its gathered enough power to last you a conversation or a safe trip to your charger and electric point.
