I've little experience in the nitty gritty of electronics so am looking to inexpensive modules that can help me achieve my goals. Specifically I have ESP32 (3.3v) and Arduino Nano (5v) projects that I would like to power with LiPo (3.3v) batteries. Ideally, the project should be able to be powered by the battery alone, and still continue to operate when plugged into a USB power source, while also charging the battery.
I'm trying to understand whether a TP4056-type charging module like this one on AliExpress (https://www.aliexpress.com/item/1005001621934354.html) will fit the bill (charging the battery AND powering the project) or whether there are some serious gotchas that I need to consider?
I've read many questions on this SE and most of the answers get a bit too technical for me. I do want to learn the nitty-gritty, but for now I just want to get my project off the ground and it seems a fairly common use case.
Update: generally USB power banks are too large / overkill to be an option for the very small footprint, low power projects I have in mind - plus they tend to be expensive in comparison to a $3 module and a $5 battery.
