Relay Camera Couplers work in tandem with the Case Relay Camera Power System to keep your camera powered continually with an external 5V USB battery pack or wall power. The Relay Coupler is simply an insert for your camera battery cavity that enables powering the camera via Case Relay Camera Power System. The coupler does not contain a battery or hold a charge.

Infinite Power for Your Camera

The Relay Camera Coupler combined with the Case Relay Camera Power System provides constant, uninterruptable power for your camera and is perfect for time-lapse photography, photo booths, video production and power-hungry LiveView shooting or any long day on the set. Need more power? Hot swap in another power bank and continue shooting while never losing power to your camera.
