A wireless computer game controller with rechargeable batteries that may be recharged while the batteries are installed on the controller and/or while the controller is in operation. Disposable batteries may also power the controller. In one embodiment, a communication cable connects the controller with a stand-alone computer game console such that the rechargeable battery pack is recharged directly from the game console through the communication cable. The cable not only establishes a communication link to facilitate the transmission of both command signals and audio/video signals between the controller and computer device, but it also deliver a recharge signal to the battery pack through the game controller. In another embodiment, the rechargeable battery pack is recharged through a power cable that establishes a power link with the wireless adapter assembly. A stand-alone cradle may be provided to receive either the controller while the batteries are mounted to the controller or the battery pack separate from controller. The cradle may be part of the wireless adapter assembly that converts the game console into a wireless transmitter/receiver.
