Direct Power
The Autonome is a mobile phone concept with a unique charging feature. The regular way to do this will be to directly plug-in the phone to the wall socket, negating the use of any cables. Alternatively, you can detach the specialized module, tank it up and then hook it back to the phone and transfer the juice.
This ways you get the freedom to use the phone whilst charging the extra ammo. I love the magnesium unibody frame designed for this, and of course the practical solution for charging. Ideal for travelers too!
