I did some pretty thorough testing on mine to put it through its paces. USB-C PD output starts/maxes around 60W with a fresh battery - but it settles in around 45W once you're down below 60% or so - hence the rating.
These are also nice to have for getting a good idea of how your older batteries are holding up. I recorded total power output (watt hours) to a 14" macbook pro with a USB-C meter, and I was pretty surprised that all my M18 batteries delivered >=85% of their rated capacity - even my 6+ year old 9.0 high demand battery.
Technically? Sure, I guess.. as long as you keep the total power draw at or under its rated 175W.. but it goes without saying it is super wasteful to charge other batteries like that, because you're converting DC to AC, then AC back to DC - and both of those steps are lossy.

It doesn't charge the battery via USB like the Ryobi inverter does, lame.
