Dell WD22TB4 Thunderbolt Dock

The Dell WD22TB4 is a Thunderbolt 4 docking station built for commercial laptops. It delivers 180 W of power through the included 19.5 V 9.23 A adapter and adds two Thunderbolt 4 ports, two DisplayPort 1.4 outputs and one HDMI 2.0 port. Three USB 3.2 Gen 1 Type-A ports, two USB 3.2 Gen 2 Type-C ports and a Gigabit Ethernet jack complete the expansion. ExpressCharge reaches 80 % battery in one hour.

Suits multi-display desks not travelers

Professionals who run two 4K monitors and need high-speed Thunderbolt peripherals on a single cable will benefit. The dock requires a Thunderbolt 3 or 4 host port and the 180 W brick, so ultra-portable users without those connections should look elsewhere. Buyers who need more than three 4K outputs or extra Type-A ports also need a different solution.

Two Thunderbolt 4 ports decide fit

The defining spec is the pair of Thunderbolt 4 ports that carry video, data and up to 180 W charging simultaneously. If your laptop only offers USB-C without Thunderbolt alt-mode the dock will not provide its full video bandwidth or power delivery. Confirm Thunderbolt host support before purchasing.

Questions about this item

How much heat or fan noise does the 180 W power supply produce when the dock runs all day?

The dock includes an 180 W AC adapter rated at 19.5 V and 9.23 A; it has no built-in fan, so heat and noise stay minimal during continuous use.

What must my laptop already have to use the two Thunderbolt 4 ports and three video outputs?

Your notebook needs a USB-C port that supports Thunderbolt 4 or Thunderbolt 3 with DisplayPort Alt Mode to drive the two DisplayPort 1.4 and one HDMI 2.0 connections.

Will my older USB 3.0 Type-A peripherals work with the dock's USB 3.2 Gen 1 Type-A ports?

Yes, the three USB 3.2 Gen 1 Type-A ports are backward compatible with USB 3.0 and USB 2.0 devices.
