Case Relay Camera Power System

Power your camera with any 5V external battery pack or AC power source

The Case Relay Camera Power System lets you power your camera continually with any USB 5V battery pack or wall power, providing peace of mind knowing you have an uninterrupted power source for your camera.


  • 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, Fuji, and Olympus cameras. A Relay Camera Coupler (sold separately) is required to use Case Relay Camera Power System.

How it Works

Simply insert the Relay Camera Coupler directly into the camera battery port. Then attach the Relay Camera Coupler to the Case Relay Camera Power System and power your camera with any standard 5V USB 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.

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.
