Uninterruptible Power for Your Camera

With Case Relay, you’ll never run out of power and never need to stress about forgetting your camera batteries. If you’re shooting and get low on battery power, simply swap out external batteries throughout your shoot. Case Relay’s internal UPS battery will keep your camera powered while you exchange external batteries. Utilizing a wall outlet or external batteries, you could in theory shoot forever with consistent power flowing to your camera through Case Relay.

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 the included 10,000mAh Rock Solid External Battery Pack or an AC power source, such as a wall outlet or generator using the included Rock Solid Dual USB to AC Wall Adapter. Because 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.

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.

Key Features:

  • The Case Relay Camera Power System contains a 1,200 mAh battery, smaller than a traditional camera battery but enough power so you can swap out power sources mid-shoot and maintain 100% uptime.
  • The Case Relay Coupler is designed to replace your camera battery and is not considered an after-market battery, just containing wiring. The Coupler cabling runs out the rubber trap door on your camera battery compartment or battery grip, and connects to the Case Relay Camera Power System unit.
  • The Rock Solid External Battery Pack (10,000 mAh) packs a punch, providing 3 to 10 times the power of most camera batteries, depending on the camera.
  • In lieu of using a 5V USB external battery pack, you can attach a USB cable to the Case Relay and run it to the included Rock Solid Dual USB to AC Wall Adapter plugged into the wall. The USB cable acts as an extension cord and powers the Case Relay. Alternatively, you could plug the Case Relay Coupler into a Rock Solid USB to AC Wall Adapter, then a power extension cord of necessary length. This is an ideal setup for studio photographers and photo booths.

Suggested Uses:

  • Use it to power Photobooths to ensure consistent uptime throughout an event.
