Dell WD22TB4 Thunderbolt 4 Docking Station — Single Cable, Maximum Connectivity

The Dell WD22TB4 is a full-featured Thunderbolt 4 docking station that transforms your laptop into a complete desktop workstation with a single cable. With dual 4K display support, 180W power delivery, USB-C, HDMI, DisplayPort and Gigabit Ethernet, it covers every connectivity need in one compact unit.

Key Benefits

• Dual 4K Display Output: Drive two 4K monitors at 60Hz via HDMI 2.0 and DisplayPort 1.4 simultaneously.
• 180W Power Delivery: Charges your compatible Dell laptop at full speed through the Thunderbolt 4 cable — no separate charger needed.
• Comprehensive Ports: 2x Thunderbolt 4 USB-C, 2x USB-A 3.2 Gen 1, 1x USB-A 3.2 Gen 2, HDMI, DisplayPort, Gigabit Ethernet and 3.5mm audio.

Performance in Use

The WD22TB4 is ideal for creative professionals, engineers and business users who switch between home and office. A single Thunderbolt 4 cable instantly connects your Dell laptop to dual 4K monitors, wired Ethernet and all USB peripherals — while charging to full speed at the same time.

With Thunderbolt 4's full 40 Gbps bandwidth, the dock handles simultaneous dual 4K video, high-speed storage and data peripherals without bottlenecks — a notable improvement over USB-C hubs or older TB3 docks that share bandwidth between video and data.
