Question Does anybody know of a good charger board for LiPo batteries?

[secretknowledge]

I have been working on a portable Raspberry Pi project of mine (for a Zero 2 W). I found a good charger for for Li-Ion batteries that fit my requirements, but as compact and thin Li-Ion battery are very hard to come by, I am looking for an alternative circuit. I considered the Adafruit PowerBoost 1000, but it did not meet all my requirements was out of stock. Can you help?

My requirements are as followed (and I would be okay with adding extra circuit boards to achieve them all)
-3.7v --> 5v boost circuit
-2 - 3 amp charging
-On/Off switch
-Battery charge indicator (or full charge + low charge battery lights)
-Anything else I am forgetting for it to work as a permanent solution for a Raspberry pi Zero 2 W

Thanks for any help in advance!
