Thunderbolt 4 Dock with 130 W Power Delivery

The Dell SD25TB4 is a Thunderbolt 4 docking station designed for professionals who need a single-cable workstation. It delivers up to 130 W power to supported Dell laptops and 96 W to other USB-C devices. Two Thunderbolt 4 downstream ports provide 40 Gbps bandwidth for high-speed storage and displays. A bundled Dockztorm portable hub adds extra USB connectivity on the go.

Compatibility Check Before Buying

Verify that your laptop has a Thunderbolt 4 or USB-C port with DisplayPort Alternate Mode and power delivery support. The included 180 W AC adapter powers the dock, so a mains outlet is required. Maximum video output depends on host capabilities and Display Stream Compression. The 0.83 m tethered cable limits placement distance from the host machine.

Build Integration and Expansion

Four USB-A 3.2 Gen 2 ports and two USB-C 3.2 Gen 2 ports handle legacy and modern peripherals simultaneously. Video outputs include two DisplayPort 1.4, one HDMI 2.1, one USB-C DP Alt Mode and the two Thunderbolt 4 ports for up to four 4K 60 Hz displays or a single 8K panel. A 2.5 Gigabit Ethernet jack, audio combo jack and Kensington lock slot complete the I/O. Wake-on-LAN, PXE Boot and remote firmware updates simplify IT management.

Questions about this item

What cables and accessories ship with the SD25TB4, and which items must be purchased separately?

The dock includes an 180W AC adapter, a 0.83 m Thunderbolt 4 cable, and a Dockztorm USB hub rated for 5Gbps data sync. Monitors, USB peripherals and any laptop power cables are not included.

Which video outputs should I use to reach four 4K displays at 60 Hz?

Use the two DisplayPort 1.4 ports, the HDMI 2.1 port and the USB-C port with DP Alt Mode; all four can drive 4K at 60 Hz when the host supports DSC.

What does the 130 W power-delivery figure mean for my laptop in daily use?

Supported Dell laptops can charge at up to 130 W; other Thunderbolt 4 or USB-C laptops receive up to 96 W, so most business ultraportables will charge at full speed while driving four 4K displays.
