To be honest, I'm not too sure. Perhaps it was done that way to prevent overcharging?
Abrigham, that link gives me a very good idea. It will involve a shaved mini usb plug wired to the inductive charging mechanism on the cover of my phone, that way nothing will be soldered, and I can easily unplug it if the TouchStone charger isnt around. Those mats look a little too clunky to be convenient, and I'd rather rig something up for 10 bucks rather than paying for something like that (I know, I know, I'm a nucklehead for trying)
