DP Alt Mode: Yes
PD passthrough to host: 100W
Max resolution: 3840x2160@30Hz
Requires DisplayLink driver: No

Confirmed with

Notebook (generic)
No dedicated AC power supply is included — the dock depends entirely on the host laptop's own charger (plugged into the dock's PD 3.0 port) to relay pass-through power, subtracting its own operating draw from that source. 4K is hard-capped at 30Hz, which can produce visible cursor lag.
