Things You'll Need
Instructions
Purchase a Sony PlayStation 3 AC Adapter if you don't already have one. The unit includes one 4.92-foot-long USB cable (type A, Mini B) and one 6.56-foot-long AC cord.
Connect one end of USB cable into the USB port on your controller and then connect the other end into a USB port on the adapter.
Connect the AC cord into the power port on the adapter and then plug it into a wall outlet. Leave the controller alone until it is fully charged and then disconnect it from the adapter.
