DELL Precision Dual USB-C Thunderbolt Dock TB18DC 210W 40Gbps

Precision Dual USB-C Thunderbolt Dock TB18DC

The Dell Precision Dual USB-C Thunderbolt Dock TB18DC is a new docking station built for Dell Precision 7530 and 7730 workstations. It delivers up to 210W of power to charge and run these demanding mobile systems. A single Thunderbolt 3 connection handles both data and charging through one cable. Professionals who need maximum desktop expansion from a compact hub will benefit most.

Build integration and cable management

The dock measures 5.7 in wide, 5.7 in deep and 2 in high, weighing 25.39 oz. It connects through one Thunderbolt 3 upstream port using a single long cable that frees up placement around the desk. Downstream it provides two USB 2.0 Type-A ports, three SuperSpeed USB 3.0 Type-A ports including one with Power Share, plus HDMI, DisplayPort, Mini DisplayPort and VGA video outputs. A single RJ-45 jack adds wired networking while dual 3.5 mm jacks handle speakers and a headset.

Capacity and headroom

Thunderbolt 3 bandwidth of 40Gbps supports fast external storage and multiple high-resolution displays simultaneously. The 210W power delivery covers the full load of Precision 7530 and 7730 units without needing a separate brick. Systems requiring more than 210W or laptops without Thunderbolt 3 cannot use the dock at full capability. Buyers needing additional Thunderbolt downstream ports or legacy serial connections will find those absent.
