Loading or storage station?

Have only two controllers plugged, everything flashes and makes and does. After 4h mhhh still flashes. Have a controller away because I thought maybe overwhelmed ok good piece had then endured six days because I could use the other controller so as charged elsewhere and lo and behold after 6 days wow it comes to a green light. That can not be.
Conclusion that thing is a controller stand and no charger, no more and no less.
