Can someone explain to me about the adapter for my portable battery TP Link 10400mAh

Hi every one, hope you guys are doing good.

First, please forgive for my bad English.

Second, I want to ask about the charger for my new power bank. The thing is, I just bought a new power bank today and in the manuals, it wrote "Input: Up to 5V/2A". While there are only two adapters in my house: one is 5.1V/2.1A and the other one is 5V/1A, I clearly understand that I can use the 5V/1A adapter to charge my power bank (it may just take longer time), but I am not so sure if I can use 5.1V/2.1A adapter for the power bank as this has a higher voltage and current.

Thanks in advance

    Should be fine. I use a 5.1v 2a charger on my powerbank with specs 5v1a input (as well as multiple other 5v input devices).

    Both are ok. Use the 2.1 if it's a good quality charger from Belkin, Apple, or other known manufacturer. There is a huge quality difference between these guys and cheap eBay generic chargers.

    you can always use higher amp chargers on lower amp devices, the device will only pull what it can use.
