Spin on it!

No matter how sophisticated a mobile phone or any other smart device is, the battery always lets us down and like all technology without power we are back in the stone ages.
Yet at last somebody has come up with a practical way of charging up a battery without the need for a plug or charger.
All you have to do with the this battery is, take it out of the phone slip it over your finger and whizz is around this will provide enough power to allow the user call or send an SMS and still have enough power to last until a full charge is available, it’s simple and yet very effective.
