Hi, im planning to do a project where im using a esp32 c3 supermini and planning to power it through a battery. But im very confused how does that work. I'm thinking of getting something like 500mAh battery with 3.7v output. But the esp32 uses 3.3v to operate. So what is the easiest solution to get it work?
I use these tiny voltage regulator modules for ESP32 projects, powered by LiPo 3.7V batteries. They will accept input from 3.4V to 36V.
Post a link to the "supermini". Are you sure that it does not have a voltage regulator?
If it is this one: ESP32-C3 SuperMini Board
then the "5V pin" can accept any voltage between 3.3V and 6V.
Another similar regulator:
Anyway, 500mAh for Esp32 is not a lot. Make carefully your calculations.
Easier approach would be this board:

Yep i have the same one that you linked, it has the the 5V pin. So i guess i just use that then. Thanks!
A cellphone powerbank, connected to the USB input is an easy and clean solution.
Or...
A Seeed XIAO ESP32-C3 has a LiPo cell connection and built-in charging.
Leo..
