The play and charge kit is to be used in conjunction with the wireless controller. The kit comes with a battery pack and the charge cable. The charge cable attaches to a plug in the battery pack, and then uses a USB 2.0 slot on the console. When the controller is charging with the cable, the user is able to still play games. However, the controller is not acting as a wired cable, but instead there is just enough power overtop of the charging that allows the wireless functionality to work. Unfortunately, the play and charge kit does not allow wireless controllers to be compatible with PCs.
