try another one result the same. I found note on the website anker.com they said "Press the LED Power Wheel before connecting your device to activate USB-C output" that fix my problem but I try another phones e.g. Samsung Note10+, S7, Huawei P20 it no need to press wheel button. at the present I'm not serious about fast charge :) , use type-A port no need to press wheel.
It looks anker charger power bank not working properly....
