So if you manage to install the PS4 controller correctly and don't touch it after that, it will charge the device. Hence the one star. However, the controller is very difficult to install and once you do, the slightest touch will separate it from the pins. The build quality is bad. It is a brittle plastic that breaks easily. There is a "feature" where you insert the controller into the charger and then press to hook the charging contacts. Charging clicks like the controller is implanted. Oh no. The receiver clicked, but the controller is still "floating" on the base of the charger. Even a simple touch of your fingers trying to let go of the controller will knock it out of your hands. It's a piece of junk. Buy something else.
