USBC hub questions mainly charging and video output

[Frederic Muller]

Hi!

I just bought a (ONTEC) USBC hub to connect my VGA monitor to my laptop) 
with as well a PD port. Reading the poorly written manual I wasn't sure 
if that port was just to provide a charging port for a USBC device, or 
if I could plug in my laptop adapter, which would then get power from 
the HUB (as their diagram suggests), giving me back 1 of the 2 available 
TB4/USBC ports on the laptop?

I did connect 2 external monitor to the hub (1 VGA+1 HDMI port) but only 
got mirrored images. Assuming the answer above is a yes I can save one 
of my USBC ports, could I assume I would then be able to connect a 
different display to the remaining USBC port and add 1 monitor that way?

Thank you.

Fred

PD is supposed to mean that you plug the laptop power brick into the adapter and the cable from the adapter into the laptop.
I have adapters from Anker that have PD and it work fine with a Mac and a Dell.

If it mirroring then I'd assume you need to fix display settings to have dual screens.
