Charge4All offers the Charging Tube/Mat, a device that can charges up to four devices at the same time using a single power source. You can get the tube with or without a mat, but you will save $10 if you get just the tube (the mat is not really useful).
The package will include five Smart Charging adapters: iPod/iPhone, Micro USB, Mini USB, LG Chocolate, and Samsung SCH. You can get additional Smart charging plug for $4.95 each. The Charge4All Charing Tube costs $39.95.
