Requires DisplayLink driver: Yes

Ports: 1× HDMI (primario, 4K@30Hz), 1× HDMI (secundario, 2K@60Hz), 3× USB-A 3.0 (5Gbps), 1× USB-C (PD 3.0, blind/pass-through only), 1× SD, 1× microSD, 1× Ethernet (Gigabit) and 1× Audio combo 3.5mm

Notebook (generic)
The USB-C port is a blind pass-through input only — it does not transmit data and rejects video signals. Without a wall adapter plugged into that port, the dock runs entirely bus-powered from the host laptop. The hub itself draws no more than 900mA parasitically.
