Hello,
I have been using the PowerCore 20100 (Model 1271) since the 11th July 2017 and it has been an amazing product! Unfortunately, the INPUT, (USB Micro) started getting loose and I am no longer able to charge the powerbank.
On some other powerbanks, I see that there are dual inputs i.e. 1 USB C and USB Micro. I think that is a great idea! If Anker wants my powerbank back for testing, they are free to collect it.
Cheers,
Pierre
