Last Updated: September 24, 2026
The Dell WD22TB4 is Dell’s Thunderbolt 4 dock for business and professional users, and it stands out for two reasons: a modular design that lets the connection module be replaced or upgraded, and up to 130W of charging for supported Dell laptops. It is common in corporate fleets but works with non-Dell Thunderbolt laptops too. This review covers its ports, display capabilities, charging behaviour, manageability and who it suits.

Modular design
The WD22TB4’s attached cable module can be removed and replaced. Dell also supports upgrading some earlier WD19 docks with a Thunderbolt 4 module. For IT departments this matters: a damaged cable or an older connection standard can be replaced without replacing the entire dock, reducing cost and e-waste.
Display support
With two DisplayPort outputs, an HDMI port and a USB-C video port, the WD22TB4 is well suited to multi-monitor desks without adapters. Dell documents configurations up to four 4K displays at 60Hz, and 5K or 8K on supported systems with the right graphics and DSC support. In practice, what you get depends on your laptop’s GPU and Thunderbolt implementation. Base M1 and M2 Macs remain limited to one external display, and the dock does not use DisplayLink.
Charging
On supported Dell laptops, the dock can deliver up to 130W and supports Dell’s ExpressCharge features, which is enough for many Dell Precision and XPS performance models. Non-Dell laptops receive up to 90W, which covers most ultrabooks and business laptops but may be insufficient for high-performance models under load.
Manageability
For businesses, the WD22TB4 integrates with Dell’s management tools. Firmware can be updated through Dell Command Update and related utilities, and features such as MAC address pass-through, remote power control and asset reporting help IT teams manage fleets. These are strong reasons to choose it in a Dell environment.
Strengths and weaknesses
Strengths
Plenty of native video outputs, strong charging for Dell laptops, modular upgradable design, business management features and wide availability.
Weaknesses
Ethernet is Gigabit rather than 2.5GbE. Non-Dell laptops get only 90W. There is no SD card reader. The dock is larger and more utilitarian than consumer-focused docks, and the attached cable is short, which limits placement.
Who should buy it
The WD22TB4 is ideal for Dell laptop users and businesses standardising on Dell hardware, especially when multiple monitors and remote management matter. Mixed-brand users can still use it, but the extra charging and management benefits are Dell-specific. Mac users with base M-series chips should look at DisplayLink docks.
Alternatives
The CalDigit TS4 offers more ports and 2.5GbE, with fewer native video outputs. The StarTech TB4CDOCK and Belkin Connect Pro are simpler Thunderbolt 4 docks. Dell also sells USB-C docks such as the WD19S series for non-Thunderbolt laptops.
Setting it up on a standing desk
The WD22TB4’s attached cable module is relatively short, so the dock needs to sit close to where the laptop rests. On a sit-stand desk, the simplest arrangement is to place the dock on the desktop behind the laptop stand, or mount it on an under-desk shelf near the front edge. Run the power adapter cable, Ethernet and monitor cables down a cable spine with enough slack for the full height travel. Because the dock has several native video outputs, you can connect two DisplayPort monitors on arms and an HDMI screen without any adapters hanging off it. After setup, run Dell Command Update or the standalone firmware utility to bring the dock and module to the latest firmware, which often improves display wake behaviour.
FAQ
Does the Dell WD22TB4 work with MacBooks?
It generally works with Thunderbolt Macs for peripherals and charging. Display support follows the Mac’s native limits, and Dell-specific features do not apply.
Can I upgrade my old WD19 dock to Thunderbolt 4?
Dell documents upgrading certain WD19 docks with a Thunderbolt 4 module. Check Dell’s documentation for compatible models and part numbers.
Bottom line
The Dell WD22TB4 is a strong business Thunderbolt 4 dock with excellent native video outputs, up to 130W charging on Dell systems and a modular design. It shines in Dell fleets. Check Dell’s user guide for supported display configurations and your laptop’s compatibility before buying.
