Connectivity for Thunderbolt 4 laptops

The Dell WD22TB4 docking station expands a Thunderbolt 4 laptop with two Thunderbolt ports, three USB 3.0 ports, dual DisplayPort outputs, an HDMI port and an Ethernet port. It delivers up to 130W power to Dell laptops and 90W to other brands. The compact black unit measures 8.1 x 3.5 x 1.1 inches and weighs 1.29 lbs.

Sustained workload stability

Dual Thunderbolt ports maintain 40Gb/s bandwidth during extended file transfers and multi-monitor sessions without throttling. The 130W power delivery keeps the host laptop charged under continuous heavy load while driving peripherals. Passive cooling handles sustained throughput in typical office ambient temperatures.

Upgrade from single-port or USB-C hubs

Replaces basic USB-C hubs that offer only one video output and limited power. The jump is worth it when you need two Thunderbolt downstream ports for daisy-chaining high-speed storage or dual 4K displays. Not for laptops lacking Thunderbolt 4 support or users who only need a single monitor and low-wattage charging.

Questions about this item

How hot or loud does the Dell WD22TB4 get when it delivers 130W power all day?

The compact 8.1 x 3.5 x 1.1 inch chassis has no fan listed in the specifications, so it runs silently and relies on passive cooling during continuous 130W charging.

Which cables or laptop ports must I already have to use the two Thunderbolt 4 ports?

Your laptop needs a Thunderbolt 4-capable USB-C port; the dock connects with its own Thunderbolt 4 host cable, so no extra cables are required for the link.

Will the HDMI and DisplayPort outputs work with a monitor that only has DVI or VGA input?

The dock provides one HDMI and dual DisplayPort outputs; DVI and VGA are not present, so older monitors would need active adapters not included with the unit.
