If you’re looking to charge your PlayStation 4 controller on a wall, there are a few things you’ll need. The first is an outlet with a power supply, the second is an appropriate connector for the controller’s USB port, and the last is some wire. To charge your PlayStation 4 controller, plug it into an outlet and use the power supply to turn it on. Once it’s turned on, connect the USB port of the controller to the outlet and wait for it to charge. Once it’s charged, disconnect the power supply from the controller and plug it back in to an outlet.
