Review on 🔌 Kapaxen EH-5B AC Adapter and EP-5B Power Supply Connector Kit - Compatible with Nikon 1 V1, D7200, D7100, D7000, D850, D810, D800, D750, D610, D600 Cameras by Chef Buntiloy

The connector between the power supply and the battery rectifier is completely useless (by "battery rectifier" I mean the functional equivalent of the Nikon EP-5B that comes with the kit). In fact, the connection is so bad that it breaks under its own weight, and that's no exaggeration: even with the cable lying on the table, air currents or temperature changes in the room can cause the connection to break. The only way I've been able to get it to work reliably is to remove (i.e. cut off) the connectors and then solder and heat shrink the leads together. and if you have the tools and skills this thing is doable
