Dell WD22TB4 130W Thunderbolt 4 Dock Module

The Dell 9H91N is a Thunderbolt 4 dock module that turns one notebook connection into a complete desktop setup. With 130 W of charging power built in, it keeps most Dell laptops at full speed while linking every essential accessory through a single cable. The Thunderbolt 4 interface moves data at up to 40 Gbps, so external drives, high-resolution webcams, and wired networks perform as if they were plugged directly into the computer. Up to four 4K monitors can run simultaneously, giving analysts, designers, and multitaskers a generous visual workspace.

A swappable design lets IT teams replace only the connection module when future standards arrive, extending the dock’s service life and protecting budgets. Dell ExpressCharge support brings batteries to about 80 percent in roughly an hour, which is ideal for users who bounce between meeting rooms and their desks. The included 2.6 ft cable offers enough reach to hide the dock under a monitor stand or at the back of a tidy workstation.

Compatibility with Windows, MacOS, and Ubuntu makes the WD22TB4 a practical choice for offices with mixed hardware, shared hot desking areas, and home workstations where different laptops come and go. Dell backs the unit with Advanced Exchange Service, so downtime stays minimal if a replacement is ever needed.
