Does the power brick matter when charging USB-C devices? (sh.itjust.works)

Yo everyone. I'm trying to understand how USB power works with batteries, hopefully this is the correct community to ask. We have so many different devices that can be charged with USB-C, yet all the power bricks and power banks have different voltage, amps, watts. Can I use any USB-C brick or power bank with any device and battery and it must intelligently never draw over the limits of the power source?

I thought that USB-C is made for this yet I can read reports that people damaged their Nintendo Switch because of a power brick. How careful do we have to be when charging our phones, tablets, laptops, gaming devices? What exactly to look out for when deciding what to plug in where? Thank you very much for any replies.

Thank you very much. I have a follow up question. Is it OK to charge a device which has an original charger of 65W with say a 10 or 22W charger? Is it just the charging speed that's affected or are here overheating concerns as well?

If a device needs 65W and you give it 22W one of two things will happen

It will charge very slowly
It will not charge at all

There is no risks of overheating.

Yes, I had to at one point charge a macbook with a samsung tablet charger (because I left the mac brick at work). I had to shut down the mac every hour or so to let the battery get some charge in, but both the mac and the samsung plug are still working fine to this day.
