At first, I wanted to get a non-Apple 20W PD 3.0 usb-c charger but I found that there were some other chargers that claimed to be of higher watts and they were not a lot more expensive. Forgive me to be cheap and greedy because I'll probably want to get a laptop later so that I don't need to buy one more piece of adapter later, is it perfectly fine to charge my iPhone 12 mini with a higher watts Apple (e.g.30w) or non-Apple charger? Will it overheat if used with higher watts or if most adapters are just so flexible that will not drive more power/current/voltage etc than needed?
Got a tip for us?

Is the 30w or higher watt charger backward compatible with 20w one?

yes I charge my phone with an Anker 30 watt plug and it does the same charge speed as the Apple 20watt I have. Also works the same with MagSafe charger when comparing Anker and apple plug. For the mini, even a 18w plug should work since the mini doesn't use the full 20watt. Go with the most watts in a small package for the money and buy form Anker instead of some weird china brand.
The fast charging iPhones all use the USB power delivery standard. Don't think about it as a whatever wattage being the amount that is constantly coming out of the charger. Instead, think of it as that 's the max amount of power a device can request from it. So if I plug your or my iPhone into my 140W Macbook Pro charger, it'll only ever get whatever it asks for, which is 20W. That's the beauty of USB PD... you can potentially use the same charger for everything from your Apple Watch to your Macbook Pro without issue.
