Get to Know: Case Relay Camera Power System

Posted by: on Jan 13, 2017 | 3 Comments
For photographers and filmmakers who want to shoot time lapse, star trails, video, and more without being limited by their camera’s battery life, the Case Relay Power System is an invaluable tool.

The Case Relay Camera Power System introduces the first uninterruptible power system for DSLR and Mirrorless cameras to achieve consistent power with any common 5V USB battery pack or wall power.  This technology provides, for the first time ever, a hot swappable, uninterrupted power source for most DSLR and Mirrorless cameras on the market today.

Case Relay meets the demands of filmmakers and photographers for whom consistent camera up-time is critical. Stopping video or photo production to remove cameras from stands to change batteries is a challenge of the past.  Case Relay’s secondary 1,200 mAh charge, means you can swap out power sources mid-shoot and maintain 100% uptime.

Case Relay is compatible currently with many Canon, Nikon, Sony, Panasonic, Fuji, Olympus, and Black Magic cameras and can be powered by any 5V USB power bank any 2.1+A USB Wall Adapter or any Dtap (VMount) battery system.  It can also power any monitors and accessories that use the Sony NPFL Series batteries.

Here’s what you’ll need to maximize the power of the Case Relay Camera Power System:
Relay Camera Coupler

First, it’s critical to find your Relay Camera Coupler as the Case Relay cannot power your camera without one. The Relay Camera Coupler is inserted directly into your camera battery port, then connected to the Case Relay CPS – powering your camera.
