Dell Pro Thunderbolt 4 Smart Dock
The Dell Pro Thunderbolt 4 Smart Dock SD25TB4 expands a laptop workstation through a single cable. It delivers up to 130W power delivery for supported Dell laptops and 96W for other Thunderbolt 4 systems. Two Thunderbolt 4 downstream ports and extensive USB-A and USB-C connectivity handle peripherals and storage. Enterprise management features include Wake-on-LAN and remote firmware updates.
For multi-display professionals and IT fleets
This dock suits users who need up to four 4K displays at 60Hz or a single 8K panel. IT teams benefit from PXE Boot, MAC Address Pass-Through and Intel vPro compatibility. Buyers whose laptops lack Thunderbolt 4 or USB-C DisplayPort Alt Mode cannot use the video or 40Gbps data features. The 0.83m cable limits placement distance from the host.
130W power delivery for Dell systems
The dock provides up to 130W charging power for compatible Dell laptops, reducing the need for a separate power brick. Non-Dell Thunderbolt 4 systems receive up to 96W. An included 180W AC adapter powers the dock and downstream devices. Verify your laptop's Thunderbolt 4 charging requirement before purchase.
