Universal USB-C hub for mobile professionals

The HP 50H55UT Thunderbolt 3 USB-C Docking Station adds seven ports through a single cable. It works with any USB-C laptop regardless of brand or operating system. The compact hub weighs 0.30 lb and measures 5.51" x 2.76" x 0.79", making it suited for travel and hot-desking setups.

Passive cooling with 65 W passthrough power

The unit operates without a fan, so it adds no noise to a quiet workspace. It draws power from the host notebook's USB-C AC adapter to deliver up to 65 W combined output for charging and port replication. No external power brick is included or required for operation.

Dual 4K video and wired networking from one cable

HDMI 2.0 and DisplayPort 1.2 outputs drive two external monitors at 3840 x 2160 @30Hz when the host supports DisplayPort 1.4. A Gigabit Ethernet port provides a stable wired connection. Firmware updates are only available on Windows-based host systems.

Questions about this item

How do I install the 50H55UT dock and what step is often missed?

Connect the single USB-C cable to a host port that supports DisplayPort Alt Mode; the dock draws power from the laptop's own USB-C AC adapter, which must be plugged into the passthrough port for charging to work.

What maintenance or replacement will the 50H55UT need over time?

Firmware updates are released for Windows hosts only, so plan to run the HP update utility periodically to keep compatibility with new peripherals and display timings.

What limit appears first when the 50H55UT runs sustained dual-display workloads?

Dual 4K output is capped at 3840 x 2160 @ 30 Hz even when the host supports DisplayPort 1.4, and total passthrough power cannot exceed 65 W.
