Tether Tools Case Relay Camera Coupler for Panasonic DMW-BLG10

SKU CH-954Q-PQC1D

A camera coupler that draws continuous power from a USB source for Panasonic Lumix GX7 cameras using DMW-BLC12 batteries

  • Uninterrupted shooting via external 5V USB power
  • Coupler fits Panasonic Lumix GX7 battery cavity
  • Works with Case Relay Camera Power System
  • No internal battery — draws power continuously
  • Essential for time-lapse, video and LiveView sessions

Panasonic GX7 Coupler

This coupler replaces the DMW-BLC12 battery in Panasonic Lumix GX7 cameras. It connects the camera to the Case Relay Camera Power System for continuous power during long shoots. The unit draws from an external 5V USB battery pack or wall source. Photographers running time-lapse, photo booth or extended LiveView sessions use it to avoid battery changes.

Installation Notes

Insert the coupler into the battery cavity exactly like a standard battery. Connect the cable to the Case Relay hub and then to a 5V USB power bank or mains adapter. The coupler holds no charge itself, so the external source must stay connected and powered. A loose USB cable or an under-powered bank will cut power mid-session.

Pre-Order Checks

Confirm your camera is the Lumix GX7 and that it normally uses the DMW-BLC12 battery. Verify you own or plan to buy the separate Case Relay Camera Power System hub. Ensure you have a 5V USB power bank or wall adapter with enough current for continuous operation. The coupler alone cannot power the camera.

Questions about this item

How do I verify the coupler is delivering power to my Lumix GX7 after connecting it to the Case Relay system?

The camera should operate continuously without battery drain while the external 5V USB power source remains connected and switched on.

What comes in the box and which additional items are required to run the system?

The box contains only the Relay Camera Coupler; you must purchase the Case Relay Camera Power System and a 5V USB battery pack or wall adapter separately.

Which version of this coupler matches a Panasonic DMW-BLG10 battery slot?

This specific model is built for Panasonic Lumix GX7 cameras that use the DMW-BLC12 battery, so it fits that battery cavity directly.
