Powering G7 X Mark III when used as USB webcam?

adayley — Thu, 31 Dec 2020 06:06:38 GMT

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

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.

Take a look at the door to the battery compartment. Is there a rubber flap on it just big enough to allow a wire to pass through?

Mark III does not have that flap.

As you can see from my original repy, the MKIII is listed as compatible, but if you say there is no flap then it won't work.

If it is compatible, then it should work somehow. I looked at the battery door at B&H, and there is no flap.

Might have to chalk this one up to an error on the Canon website?

We shall see how my Mark III reacts when the generic "dummy battery" power adapter gets here in a couple of days.

The Canon website is NOT in error!

I ordered this power adapter from Amazon: Glorich ACK-DC110 Replacement AC Power Adapter Kit for Canon PowerShot

It arrived today. I took just a few minutes from my busy day quickly check how it works for the PowerShot GX 7 Mark III.

It powers the camera while the battery compartment door is still open!

So, now I only have to worry about mounting the camera in a way that is stable while the battery compartment door is open to allow the cord to enter.

That is interesting, I wonder how it bypasses the battery door switch interlock.

I ASSUME the battery door switch interlock is software controlled in the Mark III. And the system can tell if the power device is a battery or a dummy battery.

If battery then honor interlock switch,

else if dummy then ignore interlock switch.
