Tether Tools Relay Camera Coupler for Nikon Cameras with EN-EL15 Battery
Pair your select Nikon camera to the Case Relay System with this Relay Camera Coupler from Tether Tools. In this case, it takes the place of the EN-EL15-type battery pack and provides a connection to the power source for long-term, continuous operation of your camera. This setup can easily be swapped out with another coupler to provide you with compatibility across camera systems.
D850 and D500 require use of official Nikon EP-5B Power Supply Connector and do not support the CRN5B Relay Camera Coupler.
