Note: 1, When you use the PB960 power pack, must put AA or Li-ion batteries into the flash together, besides Metz flashes

2, You need to depart the "battery Chamber" in the bottom with Control Unit in the top, let AC power connects only with battery chamber to charge. Because the "Control Unit" is a discharge object.
