Single-cable Thunderbolt dock

The HP Thunderbolt Dock 120W G2 connects a compatible HP notebook through one Thunderbolt 3 link and immediately adds wired Ethernet, audio, multiple video outputs and extra USB ports. It supports the Elite X2 1012 G1 and G2, Pro X2 612 G2, EliteBook Folio G1, EliteBook x360 1030 and 1020 G2, EliteBook 1040 G4, EliteBook 800 and 700 G5, ProBook 600 G4 and 400 G5, and ZBook 14u and 15u G5 models.

Sustained 120 W delivery

The 120 W power rating is maintained during continuous operation, so the host notebook charges while driving two 4K displays and attached peripherals without throttling. Thermal design keeps output stable across long work sessions rather than only in short bursts.

Thunderbolt 3 bandwidth ceiling

A single Thunderbolt 3 connection carries video, data and power simultaneously, limiting total throughput to the interface’s native ceiling. Users who need more than two external displays or higher aggregate I/O bandwidth cannot exceed that limit with this dock.

Questions about this item

How much power does the 120 W dock draw when it is running all day?

The dock is rated at 120 W and delivers up to 15 W through its USB-C DisplayPort output, so sustained load will stay within that envelope.

What must my laptop already have for this dock to work?

Your laptop needs a Thunderbolt 3 or USB-C port that supports video and charging to use the single-cable connection.

Will the two DisplayPort outputs and VGA port work with the older EliteBook 800 G5 I keep?

Yes, the EliteBook 800 G5 is listed as compatible and can drive two 4K displays through the dock's DisplayPort and VGA connections.
