If your phone has an input of 5V/1A and you are trying to use the USB port with 2.1A output in your power bank, it won’t speed up the charging at all. It is better to use 5V/1A if the input is the same, and only if you have a powerful device with battery that can take the 2.1A speed, you can use that for faster charging.
