Compact Thunderbolt dock
The HP Thunderbolt Dock 120W G4 is a 98 x 98 x 68 mm port replicator that connects a laptop through a single Thunderbolt cable. It targets mobile professionals who need instant access to multiple displays, wired networking and peripherals at a permanent desk.
Single-cable desk integration
One upstream Thunderbolt 4 link carries video, data and up to 100 W of charging power to the host notebook. The dock adds two DisplayPort 1.4 outputs, one HDMI 2.0 output and a USB-C DP alt mode port for up to four 4K displays plus three USB 3.2 Gen1 ports and one USB 3.2 Gen2 front port at 10 Gbps. A gigabit Ethernet jack and Kensington lock slot complete the stationary kit.
Sustained multi-display operation
HP Sure Start firmware protection meets NIST 800-193 requirements and guards the dock against persistent threats during long sessions. The 120 W power supply maintains stable 100 W delivery to the notebook while driving four 4K outputs and all attached USB devices without thermal throttling.

Questions about this item
What thermal limit appears first when the 120W dock runs continuously?
The unit is rated to deliver up to 100W of power to a connected notebook; sustained loads beyond that level will trigger the dock's internal protection before any other limit is reached.
How much fan noise and heat does the 120W G4 produce during all-day operation?
The dock uses passive cooling with no moving parts, so it generates no fan noise and only moderate warmth across its 98 x 98 x 68 mm chassis.
Which laptop port must I already have to use the Thunderbolt 4 connection on this dock?
Your notebook needs a USB-C port that supports Thunderbolt 4 or USB4 with DisplayPort Alt Mode to enable the single-cable link and up to four 4K displays.
