Key Features

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.

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.

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

More cost effective than purchasing multiple proprietary camera batteries. Power sources are non-proprietary. Power your camera with the same 5V battery you use to charge phones or tablets.

Never need to charge camera batteries again. And never run out power. Compatible with most Canon, Nikon, Sony, Panasonic, Fujifilm, and Olympus cameras. Check to confirm your camera model is supported. A Case Relay Camera Power System (sold separately) is required to use the Relay Camera Coupler.
