I have two Canon R8s and recently purchased a monitor and a Neewer PS050E V-Mount battery to power the monitor and camera. I have run into an issue where power isn't being delivered to the camera via USB-C. This happens on both camera bodies.
The Neewer will charge via USB-C if the camera is turned off, but when I turn the camera on, it stops delivering power according to the display on the Neewer battery. I have tried multiple 60W USB-C cables, as well as the USB-A port from the Neewer to USB-C. I also tried a different power bank and got no results. Firmware is updated to most recent (1.4). The manual says it should be capable of doing this so I'm confused.
I have seen multiple videos of people with similar setups (including one guy using the same battery and an R8) and cannot figure out why mine aren't working. Does anyone have any insight? And if I can't get it working via USB-C, would a dummy battery to D-TAP be the next best option?

Greetings ,
I'm sure a dummy, battery and DTaP would work, but the USB-C PD option should also work just fine.
I checked the specs on the Neewer and it definitely meets or exceeds power requirements. 45 w 9v, 3 amps.
The only thing that comes to mind is the cable you are using is data and not rated for power delivery? The setup you have however should work.

I am of a similar view to Rick, change the USB cable, make sure to get one that is USB-C to USB-C and supports at least 100W just to be sure. A USB-A to USB-C cable is not able to transfer the required power.
