Relay Camera Couplers work in tandem with the Case Relay Camera Power System (sold seperately) 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.

Simply insert the Relay Camera Coupler directly into the camera battery port, attach it to the Case Relay CPS and power your camera with the included Rock Solid External Battery Pack or an AC power source using an USB to AC wall adapter or use the ONsite D-Tap Battery with V-Mount. Because Case Relay also has its own secondary internal 1200 mAh battery, if your external battery runs low you can easily hot swap the external battery and not lose power to the camera.

• Insert Relay Camera Coupler into camera battery cavity
• Completely close battery door allowing coupler cable to exit through the rubber trapdoor
• Battery door must be completely closed for the Case Relay Camera Power System to properly function
