Tether Tools Case Relay Camera Power System

The Case Relay is a universal power supply that provides continuous power to cameras. It is particularly useful for recordings where the camera requires a constant power supply for an extended period and the battery cannot be changed. This is especially important because changing the battery would inevitably shift the frame, which would be very cumbersome during long video or time-lapse recordings. Thanks to the Case Relay, such battery changes are no longer necessary. There are numerous separately available adapters for the battery compartments of DSLR and mirrorless cameras. The Case Relay can be directly connected to a power outlet via the built-in USB cable and a separately available plug adapter to supply the connected camera with mains power. If the Case Relay is powered by a power bank, it can be charged while connected to the Case Relay. The power bank can also be swapped out during operation, as the integrated lithium-ion battery of the Case Relay ensures there is no power interruption. This allows the camera to be continuously powered without relying on a power outlet.
