Don't wonder if your controllers are already charged. The PG-9180 charger features 2 built-in, easy-to-read indicators that will provide you with the most important information.
They light up red while charging. When the pad is already charged, the indicator color changes to green.

The use of the charger is incredibly easy. All you need to do is connect it to a power source and then place the controllers on it.
The solution used will also help you stay organized – no more tangled cables and no need to plug each controller into a separate socket.
