i can use 20W quick charging adapter for iphone 11

If I can add my two cents to the correct answer you got from Stedman1, be aware that the charger doesn’t “push” power; it just supplies the power “drawn” by the device, so you can use even a more powerful charger.

Yes.

No it will not affect the battery. It would not matter which you use.
