Can I connect two portable screens to one laptop?

I assume that the pen from HP, for example, does not work? is there a screen, similar to this one, that can be operated with a pen (can be written with a pen)?

I no longer have a free slot with USB-C on my PC. Would a connection via the HDMI plug (PC) to USB-C (monitor) be possible? Does HDMI also transmit the power for the monitor?

Unfortunately, DisplayPorts do not support power transfer.
In addition, the display does not have the option of connecting it USB-C to USB-A.
The Asus Zenscreen would be more suitable, as it supports USB-C to (conventional) USB-A connection.

The power supply for this display is via USB-C. If the adapter used does not supply power to the USB-C output, it will not work. Therefore, it is best to use the supplied USB-C coax and connect it to a computer with USB-C (no Thunderbolt required). Daniel Waeber
