Infinite Power for Your Camera

Need more power? Hot swap in another power bank and continue shooting while never losing power to your camera.

How does it work?


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.
