description Dell WD22TB4 Thunderbolt Dock Overview
Designed for business workstations, the Dell WD22TB4 brings Thunderbolt 4 connectivity into a dock with USB connections, Ethernet and several display outputs. Compatible systems can drive dual 4K displays, although the exact display arrangement depends on the laptop and connection. Its modular design and Dell management features make it particularly relevant to organizations using supported Dell computers. The standard power adapter is rated at 180W, with up to 130W charging available to compatible Dell laptops.
Adapter power is not the same as the amount delivered to the computer, and demanding workstations may still require their own charger. Unlike some earlier Dell docks, this model does not include analog audio sockets. Its appeal is a centrally managed workstation connection rather than portability or an unusually small footprint. For business users, the distinguishing features are integration with the Dell ecosystem and the ability to connect desktop equipment through one host cable.
