Did you do any resting to see what the charge rate is for the cells with any given charger (wall wart/supply)? Can it actually make use of PD 3.0 for input? I read the review a couple of times but if this was mentioned, I guess I missed it.

I did not test charging speeds. It claims to be able to charge at 2A per bay simultaneously, and that would require PD input to get the necessary wattage.

OK. THX. I guess then that it is plug and pray. No adjustable charge current? 2 amps is a bit hot for some of the 18650s that I use. It still is somewhat attractive for just the power bank functionality. Or maybe an occasional travel charger… with the right cells.
Anyway, thanks for the review!

I had a friend who used one of these sort of power banks to power a Pi. It had the “flaw” that when you plugged the power bank into an external charger while powering the Pi, the Pi would reset. So, I think it would pause power output for a few milliseconds when changing modes. Most of the time, my friend liked the “flaw” however, I could have used a unit that did not have this “flaw” and instead behaved more like a 5v DC UPS.
