I just bought the PowerCore III 20K power bank (model: A1364). This model’s single USB-C port is supposed to support Power Delivery.
I own a USB-C cable (both ends) that has a LED display at one end that shows the actual power going through while charging. When I connect this cable from my Samsung Fold 3 phone to a desktop charging station that I have (which supports PD), the LED shows “PD 14 W”. This is expected.
HOWEVER, when I connect the same cable from my phone to this Anker power bank, the LED shows “9.3 W”. There’s no “PD”. Seems like the advertised specs is wrong and Power Delivery is not supported in this bank model. Can someone confirm/deny this?
BTW, don’t think it’s a defective product I got, because I bought two of these banks and neither appears to support PD.
