Dell Pro Thunderbolt 4 Smart Dock SD25TB4 (210-BRQK), 4-Display 130W Dock - Like New

The Dell Pro Thunderbolt 4 Smart Dock SD25TB4 (Dell P/N 210-BRQK) is an enterprise-grade Thunderbolt 4 docking station built for demanding multi-display workflows, hybrid offices, and IT-managed laptop fleets. A single Thunderbolt 4 / USB-C cable delivers up to 40Gbps of data, video, and power to the host laptop, driving up to four external displays while charging supported Dell notebooks at up to 130W (96W on non-Dell USB-C/Thunderbolt 4 systems). Built-in remote management — including Dell Device Management Console support, Intel AMT, MAC address pass-through, and PXE Boot — lets IT teams deploy, update, and troubleshoot docks at scale without touching the host PC. The SD25TB4 works with Windows, macOS, ChromeOS, and Linux systems that support Thunderbolt 4, USB4, or USB-C DisplayPort Alt Mode.

This is a Like New unit — fully tested and 100% functional. The dock may show very minor cosmetic signs of handling or light use (such as faint marks on the housing) that do not affect performance. The original packaging may be opened or may not be included.
