Complete specifications and features

Dell WD19TB and WD19TBS are Thunderbolt 3 docking stations that enhance laptop connectivity with multi-display support (via DisplayPort 1.4 and HDMI), USB-A/USB-C expansion, Gigabit Ethernet, and up to 130W power delivery to Dell systems through an integrated Thunderbolt cable.

Model Differences

WD19TBS is the simplified/streamlined version of WD19TB, removing certain legacy interfaces such as the 3.5 mm audio jack and simplifying internal modules. Functional capabilities like port layout, display support, and power delivery remain effectively the same.

Frequently Asked Questions

Find answers to common questions about WD19TB / WD19TBS with 130W Power Delivery

The number of displays that can be connected is limited by multiple factors including CPU, GPU, interface capabilities, and data transfer rates, not just the docking station itself. This is a multi-faceted limitation rather than a single constraint imposed by the docking station alone.
Smart Docking (SD series) is Dell's new docking station lineup introduced in 2025. Building upon traditional docking stations, it adds features such as wireless connectivity and remote management capabilities. Smart Docking can receive firmware updates independently, without requiring connection to a host computer.
