Powering G7 X Mark III when used as USB webcam?

[adayley]

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

[adayley]

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

The camera will not turn on unless the battery door is closed....here is a list of compatibility for that adapter off the Canon website and I do not see the Mark III:

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

Can't use that adapter and USB for video at the same time. Maybe the only way to externally power the Mark III and use it as a webcam is to have the video come through HDMI. That way USB can provide the power.
