G7 X Mark III - battery dying after 2-1/2 hours when using Webcam Beta, any advice?

[chrisgagne]

I am using a PowerShot G7 X Mark III hooked up to a MacBook Pro 13" directly with an genuine Apple USB-C cable. I am finding that the camera runs out of battery after 2-1/2 hours and shuts off. I thought the USB-C would be enough to operate the camera indefinitely; apparently not? Any advice?

Hey guys!

I'm not tech support, but I wanted to pop in and make sure you're all aware of the handy Getting Started Guide that is posted on the Live Stream microsite at canon.us/livestream

It points out that the "USB Power Adapter PD-E1 cannot be used at the same time as USB Interface Cable"

That would mean that you'd have to either charge the camera by USB or use the data transfer function (webcam) by USB. Instead, you'll want the "dummy battery," AC Adapter Kit ACK-DC110.

Hi Stephen,

thank you. It would be a great improvement to an otherwise great product as it is, if one could use power and data transfer via USB at the same time. 🙂

My iPad Pro (12-inch) charging block will charge the camera via the USB-C port.

It was plugged into a MacBook Pro that can deliver 15 watts via USB-C (the cables easily handle 5A, which is plenty). The Canon NB-13L battery is only 4.375 watt hours and powers video recording for at least an hour. There is absolutely no way the Canon requires even 15 watts of demand when recording video as the battery would last less than 18 minutes in that condition.

This isn't about the USB -> USB-C adapters. The fundamental issue is that Canon seems to have deliberately designed a product to not operate while using power from USB-C so that they can charge you hundreds of dollars for a dummy battery pack instead of you using a readily available, industry-standard power adapter that you likely already have.

Shame on Canon for their blatant cash grab from their loyal consumers. Fool me once...
