18650 batteries still the best option for projects? (aussie.zone)

I've got a few projects on the list which will be battery powered. I'm thinking of using 18650s just because of how ubiquitous they are, but I know there's other options out there. Are they worth it?

E-ink calendar
Solder fume extractor
Lora station
Portable "trail camera"
Home assistant remote controls Etc etc etc

Yeah, I get you!

What I've done in the past is just buy a few charging boards with an integrated holder. USB/12v input, 3.3/5v regulated output. You can even get ones with solar. Then my circuitry can be independent of the power system.

And you can get UPS battery boards for $3 USD often and in various output voltages. Definitely outsource your power supplies and battery managers.
