Well, guys, this might be a bit misleading here... Yes, it does support pass through charging and no, it doesn't. It basically depends on what kind of device you want to pass through charge with this product. It sure works for tablets or phones, but for a laptop which does require a bit more than what a phone does, it doesn't work, not at all. How could it possibly? ➙ The lower USB-C connector (Input / Output PD 60W) is for charging the power bank itself, obviously, while the upper USB-C connector (Output) delivers 15W (or 5V/3A) only.
You can crosscheck the original document here (take a closer look at the section "properties ➙ output"):

This stuff isn't rocket science at all, but it sure does take some research time to cut through all the marketing claims. Good luck.
