Dell WD15 Thunderbolt Dock

The Dell WD15 K17A is a Thunderbolt docking station built for compatible Dell laptops. It adds Gigabit Ethernet, multiple USB ports, video outputs and audio connections through a single USB-C cable. The unit ships with a 130W power adapter and power cord. Factory packaging and a quick-start guide are included.

Suits owners of listed Dell models needing legacy

Professionals using supported Latitude, Precision, XPS, Inspiron or Alienware systems gain RJ-45, VGA, HDMI 1.4a and mini DisplayPort 1.2 in one dock. Buyers whose laptops lack Thunderbolt over USB-C or who need Thunderbolt 3 speeds should look elsewhere. Users requiring more than two USB 3.0 ports or DisplayPort 1.4 will need a different solution.

Single USB-C Thunderbolt host connection

The dock links to the host via one Thunderbolt USB-C cable carrying data, video and up to 130W of power delivery. This single-cable design drives the three USB 3.0 ports, two USB 2.0 ports, combo audio jack, speaker output and the wired network port simultaneously. Confirm your laptop supports Thunderbolt over USB-C before purchase.

Questions about this item

Does the 130W power adapter run hot or make noise when the dock is used all day?

The 130W adapter is rated for continuous use and the dock has no fan, so it stays quiet and only warm under normal load.

Which laptop port is required for the single Thunderbolt cable to carry video, data and charging?

Your laptop needs a USB-C port that supports Thunderbolt with DisplayPort alt mode and power delivery to use all functions through one cable.

Will the HDMI 1.4a and mini DisplayPort 1.2 outputs drive 4K monitors at 60 Hz on an older Precision 5510?

HDMI 1.4a is limited to 4K at 30 Hz; mini DisplayPort 1.2 can do 4K at 60 Hz if the Precision 5510 GPU supports DP 1.2 over Thunderbolt.
