Tether Tools Relay Camera Coupler CRCE6

The Tether Tools Relay Camera Coupler CRCE6 is a battery-shaped insert that slots directly into your camera’s battery compartment, transforming how you power extended shooting sessions. Instead of relying solely on your camera’s built-in battery, this coupler connects your DSLR or mirrorless camera to the Tether Tools Case Relay Camera Power System, giving you access to continuous power from either a 5V USB mobile power pack or an AC wall plug.

With a built-in 1200mAh battery onboard, the Relay Coupler ensures uninterrupted shooting even when switching between power sources — no need to power down your camera during transitions. This makes it ideal for studio work, long events, tethered shooting, or any situation where battery life could otherwise cut your session short.

The coupler is available in multiple battery mount versions to suit different camera models. Please check the Tether Tools website for the full compatibility list to ensure you select the correct mount for your specific camera.
