Ardica has designed a jacket that is not only claimed to be able to charge your gadgets, but the battery used also gives off enough heat to keep you warm as the winter drags on.

The jacket has a concealed battery that is claimed to have enough juice to charge a mobile phone 11 times over, an iPod 20 times over or can run a dead device or power a GPS, PDA or any other personal electronic device so long as it requires no more than 10 watts of power.

Alternatively, you can have 9 hours of low heat or 3 hours of hot.
