This compares Icecat’s public interface documentation with a reproducible SpecJoin example. We have not audited the corresponding paid Icecat records.
Example: Latitude 5420 + WD19
The API lists screen setups and charging separately. One documented option uses two Full HD screens and two DisplayPort cables. Dock output is up to 90 W with Dell supply 46TR4 or 130 W with GJPT6; these are output limits, not the laptop’s power draw or charging speed.
