Docking station for Dell Precision

This Dell TB18DC docking station connects a Precision 7530 or 7730 through a single USB-C cable. It expands the laptop with two Thunderbolt 3 ports, three USB-A 3.1 Gen 1 ports, HDMI 2.0, DisplayPort 1.4, VGA, Gigabit Ethernet and a 3.5 mm headphone jack. A 240 W power adapter is included to charge the host while peripherals are attached. A Kensington lock slot secures the unit physically.

Who this suits and who it does not

The dock is built for Dell Precision 7530 and 7730 owners who need multiple displays and wired networking from one cable. It will not support laptops that lack USB-C Thunderbolt 3 connectivity or that require a different vendor’s proprietary dock interface. Buyers needing more than two Thunderbolt devices or more than three USB-A ports should look at other solutions.

Deciding specification: Thunderbolt 3 host

The single specification that determines compatibility is whether the host laptop provides a USB-C port with Thunderbolt 3 signalling. Without that port the dock cannot deliver video, data or charging to the Precision 7530 or 7730. Confirm the host port type before purchase.

Questions about this item

Does the TB18DC ship with the 240W AC adapter or do I need to order it separately?

The TB18DC includes the 240W AC adapter in the box, so no separate power supply purchase is required.

Should I choose the TB18DC for a Precision 7730 or a 7530?

The TB18DC is compatible with both the Precision 7730 and 7530, so either model works with this dock.

The 240W adapter powers the dock and delivers up to 240W to the attached Precision laptop through the Thunderbolt 3 cable.
