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!
