Powering G7 X Mark III when used as USB webcam?

[ Edited ]

Question: Can the GX 7 Mark III be powered by something other than the battery when the USB-C port is connected to the computer as a webcam?

 

Setup:

  • Laptop has the EOS Webcam Utility installed.
  • GX 7 Mark III is connected via its USB-C port to a USB port on the laptop.
  • The Mark III is operating correctly as a webcam.
  • The Mark III cannot be powered using its USB-C port because that port is the video data interface.

Is there a product or way to power the Mark III so the battery does not run out?

Thank you for the reference. I rejected that solution earlier in my research because it appears to require that the battery compartment door remain open while this adapter is in use. I guess that is the trade off in order to power the camera.

I ordered this power adapter setup: https://www.amazon.com/dp/B074KCB6TS

 

Now to figure out how to have a stable mount for the camera while the battery door is open. The door and the mount point are very close together.

The battery door will close, as usual, there is a little flap on the battery compartment that folds open for the cable to pass through it and allows the camera to mount flush

I saw that flap in review videos of the Mark II. The Mark III does not have that little flap.

I didn't note this comment before. That is a concern!

Ahhh oh yes I see it. Still, I do not see how it will work if you cannot close the battery door? The manual mentions a USB Power Adapter PD-E1
