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.

Simply insert the Relay Camera Coupler directly into the camera battery port, attach it to the Case Relay CPS and power your camera with any standard 5V external battery (commonly known as a portable USB charger, which you can get most anywhere) or an AC power source, such as a wall outlet or generator.

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

Relay Camera Coupler & Relay CPS Benefits:

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.

A Case Relay Camera Power System (sold separately) is required to use the Relay Camera Coupler.
