No, this does not support pass-through charging. I just tested this by plugging my new PowerBank into my Anker PD charger using an Anker cable, which began charging of the power bank. I then used the short lanyard USB cable to plug into the second USB port and tried charging my iPhone 15 Pro; the phone did NOT charge or even recognized that it was plugged in. I then disconnected the PowerBank from the Anker PD charger, and the phone began charging; when I plugged the PowerBank back into the PD charger, the phone stopped charging. I did NOT test this with the USB-A port, and I do not know if this is a design characteristic that can be relied on safely. Since even Anker’s bot did not “know,” I would not trust this behavior to be intentional. Best bet is to stop charging the PowerBank when beginning to charge, or consider alternatives. My wife has a very nice Samsung battery pack which does pass-through charging and it has three USB-C outlets, all of which can be used to charge or discharge. Anker also makes several wall-wart style battery packs which can be used as chargers while plugged in.
