Are ther packs that support pass through charging robustly? I have tried with three different ones and two do this sporadically and the last one lenovo go, seems to support it only from the male plug, which is next to useless. Or at least I do not have a single usb A male - usb - c female cable that would be required in most cases.

I'm using Xiaomi 20,000 mAh power bank, and passthrough works great. Mine only supports 18W out, when I have my 30W charger plugged in, the power bank charges as well.
