Combined with the Case Relay Camera Power System, the Relay Camera Coupler provides steady, uninterrupted power to your camera and is perfect for time-lapse photography, photo booth, video production, and power-hungry LiveView or any all-day location shooting. Need more power? Change power banks without interruption and continue shooting without your camera running out of power.

How It Works?
Simply place the Relay Camera Coupler directly into the battery bay, connect the Case Relay CPS to it and power your camera from any standard 5V external power source (usually called a power bank or external battery) or wall outlet, or about generator.
