I was able to find an USB Type C HUB which contains an ethernet port, another USB Type C port for Data Transfer, some spare usb 2.0/3.0 and an USB Type C input for PD (power delivery - used to connect an existing charger to recharge the computer while using the USB hub at the same time)
As now, the DP functionality seems to not work on this computer, so i have to return the hub because it's pretty much pointless for my intentions.
I bought also a cigarette lighter charger with a 45W DP port (same wattage as the original house charger) to be used in combination with my hub and my computer inside the car, but considering the functionality is not even working with the original HP wall charger, i'm better returning also this item as soon as possibile.
Vary bad feedback as now. It's a neat piece of computer, but it has so much cons..
