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 Rock Solid External Battery Pack or an AC power source using an USB to AC wall adapter or use the ONsite D-Tap Battery with V-Mount. Because Case 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, Fujifilm, Olympus, and Black Magic cameras and can be powered by any 5V USB power bank any 2.1+A USB Wall Adapter or any D-Tap (V-Mount) battery system. It can also power any monitors and accessories that use the Sony NPFL Series batteries.

“We do Dog Show Event photography. The Case Relay attached to the 10000mh battery powers the D750 that is tethered to our laptop. Before I got it we would go thru about 5 or 6 Nikon batteries in a day long assignment.

“It’s perfect to power my second Sony A7S II camera during weddings. Because I’m not with eyes on the camera most of the time, it allows me to connect any power pack. The most important thing is to allow swapping power banks without loss of power and corrupted files.”
