Maybe it’s not faulty, there are 2 kinds of USB-C chargers and you gotta get the right one for your device. I guess this one needs Power Delivery charger. I’m going to buy an Anker for my Cube i7 Book.
Indeed maybe it’s not faulty at all. As the admin did with his hub, I tried to plug it before powering up the unit and now it seems to charge while using both usb ports with no issues.
Maybe this power delivery charger is not needed for my chuwi.
