Can i charge J6(2018) in a 18w powerbank?

I am planning to buy an 18w QC powerbank.

Samsung J6 is capable of 5V/1A Charging.

The powerbank are capable of Powerbank 1 output 1 5V==2.1A/5V==1A

Powerbank 2 Output 1 5V-3A, 12V-1.5A, 9V-2A Output 2/3/4 5V-2A

I dont know this kind of number and how will it affect my phone.

Will my phone burn if i charge it at Powrbank 2 Output 1(5V-3A). Or it will charge at 5V-1A and disregard the 5V-3A. Will it affect any phone components in board? or my battery? Or my cause any overload?

I tried google to learn more but still confuse.

Hope for better explanation. Thank you so much.
