I just purchased a new power bank. It has two outputs one is rated as 5V and 1.0A and the other is 5V and 2.1A. I have a ZTE Avid Trio, I was wondering if I would damage my phone if I used the 5V, 2.1A connection for charging it? I am hoping using this output will make my phone charge faster. The power bank is 20000mAh 72Wh. I don't know what I did with the original charger I've been using for my phone, I lost the plug but still have the usb cable. The charger Ive been using is only rated at 0.7A. I looked on Amazon at other 20000mAh banks and most of them are actually rated at 5A or over.
