What it is

The Centenex Electronics CBNIKONEP-5B is a DC coupler that replaces the camera battery in compatible Nikon bodies. It provides a DC port so the Nikon EH-5B AC adapter can power the camera continuously during long shoots or studio work.

Build and connection

The unit measures 55.5 by 39.2 by 20.1 millimetres and slides into the battery compartment like a standard pack. A short lead terminates in a connector that mates with the EH-5B adapter, eliminating the need to swap batteries during extended sessions.

Practical limits

Power is only available while the AC adapter remains plugged into a mains outlet, so the camera loses mobility. The coupler works with the listed Nikon models including the D500, D600, D610, D700, D750, D800, D800E, D810, D810A, D7000, D7100, D7200, D7500 and Nikon 1 V1.
