6-in-1 USB-C Dock with 4K HDMI

The HP 2SM31PA#AB2 docking station adds six connections through a single USB-C cable. It provides a Gigabit Ethernet port, a 4K HDMI output and three USB 3.0 ports running at up to 5 Gbps. A USB-C Power Delivery input accepts up to 100 W from a separate supply and passes up to 85 W to the host laptop. The unit draws 12 W typically and 15 W at maximum.

Mobile workers needing wired networking

Users who want a compact hub for Ethernet, 4K video and three legacy USB-A devices will find the port mix convenient. The dock requires its own 100 W power adapter to deliver the full 85 W laptop charge, so buyers without a spare high-wattage supply should plan for that purchase. Anyone needing more than one video output or additional USB-C downstream ports should look elsewhere.

85 W laptop charging from 100 W PD input

The single deciding specification is the power delivery capability: the dock can pass up to 85 W to the connected laptop only when a 100 W USB-C power supply is connected to its PD port. Without that external supply the charging path is not available, so the buyer must already own or separately acquire a compatible 100 W adapter to use the charging feature.

Questions about this item

What does the 100 W PD rating mean for my laptop?

The dock can pass up to 85 W to the laptop when you connect a 100 W USB-C power adapter; the dock itself draws up to 15 W.

What does the Gigabit RJ45 port cap at in practice?

The Ethernet port negotiates at 1 Gbps, so sustained throughput will not exceed that link speed.

How much desk space does the 121 x 43.5 x 13.8 mm body need?

The unit measures 4.76 x 1.71 x 0.54 in, so it fits in a shallow tray or beside a keyboard without blocking adjacent ports.
