I received and checked the charger by taking it out of the box. Everything looked good, everything seemed to be in order, all parts were present. I plugged it in and put 2 PS4 chargers in the station to charge. While the left controller flashed a pulsing yellow light to indicate it was charging, the right controller did not light up. I thought maybe it's already fully charged. So I took it off the charger to play with it. No, he's completely dead, but he's not attacking. Upon closer inspection, I noticed that one of the wires on the docking station's right connector was bent toward the base of the connection. Very disappointing, i have a brand new dual dock charging station that can only charge one controller. I'm not saying not to buy this product, it still works one way. I think I was just unlucky and got a bad block or it was cheaply made. To be honest, I couldn't tell you.
