Relay Coupler for Sony A7 Series

The Tether Tools Relay Camera Coupler replaces the NP-FZ100 battery in Sony A7III, A7RIII and A9 mirrorless bodies. It connects to the Case Relay Camera Power System so the camera can draw continuous power from an external 5 V USB source. The coupler itself stores no energy and simply passes power through the battery cavity. Photographers and videographers who need uninterrupted runtime for studio, timelapse or live-stream work will find this accessory essential.

Studio and remote shooters only

This coupler suits creators who can stay tethered to a USB power bank or mains adapter via the Case Relay system. It is not for photographers who must move freely without a cable, for anyone who does not own the Case Relay unit, or for users of other camera brands or Sony models that take different batteries.

50-inch combined cable reach

The supplied coupler cable measures 10 inches and extends to 50 inches when joined with the relay cable, giving 127 cm of total length between the camera and the Case Relay unit. This single dimension determines whether your power source can sit where you need it during a shoot.

Questions about this item

How do I confirm the Relay Camera Coupler is delivering power to my Sony A7III after connecting it to the Case Relay system?

The camera will power on and operate normally without an internal battery installed, indicating the coupler is successfully passing 5 V USB power from the Case Relay unit.

What items are included with the Tether Tools CRNPFZ100 and what must be purchased separately?

The box contains only the Relay Camera Coupler with its 10" (25.40 cm) cable; the Case Relay Camera Power System and a 5 V USB power source are required but sold separately.

Which cable length should I choose between the 10" coupler cable and the 50" (127 cm) coupler-plus-relay option?

Select the 10" cable when the Case Relay unit sits close to the camera, or the 50" combined length when you need extra reach to a floor-mounted USB battery pack.
