Charge multiple mobile devices with one SynCh
The SynCh is a UK-based product, but I see compatibility with devices that are generally available around the world. The USB-based SynCh provides for charging multiple mobile devices via USB and a one custom charging tip. The retractable cable splits the power supply into two, so you can charge one specific device while charging or sending data to a USB device. Power can be supplied from three different sources: a standard wall outlet, a cigarette lighter in your vehicle or a computer with a USB port.
Prices start around 20 British pounds and the customizable tip adds another 6 pounds. There are hundreds of devices supported, so check the list to see if a SynCh is in your future.

The Callpod Chargepod is like this, but it can charge 6 devices at once, and they have a compatibility lost of thousands of devices.
