We caught sight of Psyclone's WildCharger
-based TouchCharge kit
for the Xbox 360 a few weeks ago but, in case you missed it, the company is also offering similar kits for the PlayStation 3 and Wii. At $49.99 the PS3 version is actually the cheapest of the lot, due to the fact that it's able to use the controller's own rechargeable battery, while the $59.99 Wii version and $69.99 Xbox 360 version each include some rechargeable batteries of their own courtesy of Psyclone. The charging pads themselves are, of course, interchangeable, and you can even charge more than one device on a single pad, although finding the necessary controller adapters separately seems to be another matter.
