HP Thunderbolt Dock G2

The HP Thunderbolt Dock 120W G2 is a compact Thunderbolt docking station designed for professionals using compatible HP EliteBook, ProBook and ZBook laptops. It provides a single-cable connection that adds multiple displays, wired networking and peripheral ports to a mobile workstation. Buyers whose laptops lack Thunderbolt support cannot use this dock.

120 W power delivery

The dock supplies up to 120 W of power over its Thunderbolt link, charging the host laptop while driving connected peripherals. If a notebook requires more than 120 W for full performance, the dock will not meet its charging needs. This single figure determines whether the unit can replace the original AC adapter.

Passive thermal design

The enclosure measures 98 by 98 by 102 mm and weighs 2.4 Lbs with no active cooling fan listed in the specifications. Heat dissipates through the aluminium chassis during normal operation, keeping acoustic output negligible. Power draw scales with attached devices but remains within the 120 W input budget.

How does the Thunderbolt connection limit what I can plug in?

The single Thunderbolt port carries data, video and charging over one cable, so all attached monitors and USB devices share that link's bandwidth.
