Things You'll Need
Instructions
Power on your PS3 or computer; any computer will do as long as it has an open, functional USB port.
Plug the small end of the USB cable into the top of the PS3 controller and the large end into an open USB port on your PS3 or computer.
Check the four indicator lights next to the USB port on your PS3 controller. If they are flashing, the controller is being charged. When the lights stop flashing, the controller is fully charged.
