Dell Pro Thunderbolt 4 Smart Dock SD25TB4

The Dell Pro Thunderbolt 4 Smart Dock SD25TB4 is a USB-C docking station designed for business environments. It provides expanded connectivity through Thunderbolt 4 technology and delivers up to 130W of power to the host device. The dock supports a multi-monitor setup with video outputs for up to four 4K displays. It integrates a 2.5GbE network port and Wi-Fi for flexible deployment.

Suited for multi-display workstations needing high

This dock suits professionals who require a single-cable connection for multiple 4K monitors, fast wired networking and wireless capability. It is not intended for users who only need basic USB-A expansion or video output on a single screen. Buyers without Thunderbolt 4 host ports will not access the full bandwidth or display capacity. It also does not fit workflows that rely on legacy proprietary docking connectors.

130W host power delivery via Thunderbolt 4

The defining specification is the 130W power delivery capability over the Thunderbolt 4 upstream port. This determines whether the dock can charge a specific high-performance laptop while driving four 4K displays. If the host device requires more than 130W for full performance, the dock will not sustain maximum load. Verify the laptop power requirement against this 130W figure before purchase.
