It looks like Astro E5 2nd Gen doesn’t work with Huawei P20 Pro. When you connect E5 with phone it starts to charging, but after a second or so charging stops and restarts again. And after that it just keeps restarting charging.
Probably E5’s powerIQ and Huawei’s SuperCharge just are not compatible. I just wonder if any one else has run into same problem and is there any way to get these work together? Or is the only solution just to retire a reliable old powerbank?
