This is very helpful, thank you.

I did program the PD trigger to limit to 9V. So, I've seen it only draw 5V when hooked up to a smaller supply.

Do you have recommendations for components to make a circuit that could quick charge the battery at a high current when hooked up to the right power supply, but also limit draw for lower current rated supplies? I couldn't seem to find this with my own searches.

Edit: BTW - it seems as thought the TP5100 board that I had purchased limits draw to 2A: link. I realize the charging module itself probably can support 3A, though perhaps there is additional hardware on this specific board to limit draw to 1-2A. Please correct me if I'm wrong on that. Appreciate the help!
