I use a 3rd party charger, a USB PD supply from Anker. It cost about $30, so not cheap but its a standard, so shouldn't be a problem. I also received a Canon branded USB-C-PD charger with the grip for my EOS R. I have a cheap Chinese made DC Coupler which I first used on my 5D MK III, then my 5D MK IV, and on my EOS R. It works fine with my Case Relay power supply for cameras with LP-E6 batteries. I would not recommend it with a unknown power supply, but it will probably work with most of them.Psst, the answer is no.
My original use for the Case relay was to be able to use a USB battery to power my 5D MK IV continuously with live view operating during the Solar Eclipse. It worked well for that. I also use it in the studio when running continuously with live view.
