I have been ripping apart these $5 Walmart power banks for that purpose. It’s just a 3350mAh 20650 battery and that little board with a USB out and Micro USB in. Should give you charging protection if you charge with the micro USB, and discharge protection going out through the other USB (or soldering to those points like I did).

Only issue I had was the boards not exactly liking my blinding bright LED projects, like they’re pulling too much current for those 0.5A chargers. I grabbed a larger 1.0A charger but have yet to rip that one apart.

I’m sure there’s a better way to do it, but this was easy.

Time for more trial and error...

If the small one powers it through that USB cable fine, there needs to be something more. Like maybe it needs to be connected to something more than just the two pins.
