Hi Jerry,

As I mentioned in the recent powerbank post, I run a Mele Quieter 3Q (the 3C was not available at the time) and it runs without any issue via a PPBA with my 12V LiFePO4 battery but I had to make/convert a USB-C cable such that one end is USB-C (for the Quieter) and the other end is 5.5-2.1mm round connector that connects to the PPBA.

Now that the Quieter 3C is available, it will likely make life simpler by being able to use USB PD powerbanks. The only drawback I can see is that you may require either a big powerbank or a number of them so you can run PC, mount, cameras, focuser, dew heaters, etc... since all that equipment may require a fair bit of power to operate. But... it would make for a nice portable astrophotography system as a few powerbanks are much lighter that my LiFePO4 battery.

Keep us posted with your decision and findings.
