Fwiw, should you need it, there are AA lithium batteries with a usbc slot for charging and they deliver 1.5v. I bought a pack out of curiosity and was very pleasantly surprised.
Make sure to get some that mimic battery power loss at the end. Some models just shut off when they are empty and others slowly reduce the voltage so that battery indicators on devices are able to pick that and display a warning to change batteries soon.

I didn’t know those existed. I read they just stay at 1.5 until they run out. Now I’m not sure what mine are, if they exhibit this behavior 🤔
