What is best charging output for Galaxy S10+ charger?

[whatever61]

Hi all,

I am a bit confused with the charging output for the S10+.

I read oniline that it can charge max. 15W. So for example 5V/3A.

However, I have bought some adapters that are FastCharge, but it shows 5V/2A. so the charging speed is 10W, if I understand well.

1. Can it be FastCharge and 10W instead of 15W?
2. If the charger is let's 5V/2A but doesn't support the FastCharge technology it will not charge on 10W?
3. For my charger and powerbank I should ideally look for 5V/3A and FastCharge 2.0?

Thanks!
