I just wanted to report back that the converter/charger system and battery listed below work.
I tested them last night in silent shutter mode. The M6ii shot 30 second exposures continuously for over 9 hours in. It looks like the battery still has more than half a charge remaining, but I did not look at the charge level before I started. So, I'm not sure where the battery level was when I started. This combo is more than enough for an entire night of exposures for star trails which is the original problem I needed to solve.
Thanks to everyone for their helpful comments.

So I had a chance to test it yesterday and all I can say is that this is one of the best accessories I have purchased for the M6ii.
I paired with my small RavPower 10000 mAh powerbank, even while charging my phone using the other port it lasted forever.

For those considering the $60 Canon OEM battery or the AC adpater, this is a much better option. It is actually better than power through USB, since this is a more solid connection, leaving the USB-C port free for other uses.
Now is hard to justify getting the one who connects to an AC outlet given that the powerbank is portable and last long enough
Highly Recommended !
Ok, I found an issue with my powerbank.
Most powerbanks will shut down their charging port once the current demand goes down.
When the M6 II goes into sleep mode and you try to wake it up, it won’t since the power source has been cut down already.
To turn on the powered port again you need to unplug and replug the USB cable.
The fix for this is to have a powerbank that can work with low power devices or have a low power mode.
The coupler manufacturer explains this in the instruction manual and recommends two powerbanks models.
Another solution is to disable the sleep mode timer in the camera, display off is fine but sleep is too low of a draw and will shut down the powerbank and the camera completely.
Just a thought, but could you hack apart your cable and add a resistor in parallel to maintain a minimum current draw?
or get a USB LED light or something.
Does the camera "inactivity" shut down the entire power bank, or just individual ports? If it is individual ports, I suppose you could still use your USB LED by adding a USB "Y" splitter cable. That brings up another issue though... I am assuming the PD voltage requested by the M6 II is higher than the typical 5V USB output.

Fujifilm's X-H2 is a high-resolution stills and video camera, that sits alongside the high-speed X-H2S at the pinnacle of the company's range of X-mount APS-C mirrorless cameras. We dug into what it does and what it means.
Holy Stone produces dozens of low-cost drone models aimed at consumers. We look at the HS710 and HS175D to see if they stack up to other sub-250g offerings. Are these secretly great or more like toys?
It's small, light, cheap and extremely wide but is it any good?
After weeks with a production Fujifilm X-T5, Chris and Jordan have some final thoughts.
The EOS R6 II arrives in one of the most competitive parts of the market, facing off against some very capable competition. We think it rises to the challenge.
Above $2500 cameras tend to become increasingly specialized, making it difficult to select a 'best' option. We case our eye over the options costing more than $2500 but less than $4000, to find the best all-rounder.
There are a lot of photo/video cameras that have found a role as B-cameras on professional film productions or even A-cameras for amateur and independent productions. We've combed through the options and selected our two favorite cameras in this class.
What’s the best camera for around $2000? These capable cameras should be solid and well-built, have both the speed and focus to capture fast action and offer professional-level image quality. In this buying guide we’ve rounded up all the current interchangeable lens cameras costing around $2000 and recommended the best.
Family moments are precious and sometimes you want to capture that time spent with loved ones or friends in better quality than your phone can manage. We've selected a group of cameras that are easy to keep with you, and that can adapt to take photos wherever and whenever something memorable happens.
What's the best camera for shooting sports and action? Fast continuous shooting, reliable autofocus and great battery life are just three of the most important factors. In this buying guide we've rounded-up several great cameras for shooting sports and action, and recommended the best.
