HP Thunderbolt 280W G4 Docking Station

This docking station delivers up to 230 W charging for compatible workstation laptops through the combo cable and up to 100 W USB-C Power Delivery for standard USB-C devices. It includes a 280 W AC power adapter and a Dockztorm portable hub with up to 5 Gbps data sync rate. The bundle contains two units for multi-desk setups.

Connectivity and display support

Suits users who need a Thunderbolt 4 dock with 2.5 Gigabit Ethernet, one HDMI 2.0 port, two DisplayPort 1.4 ports and one Thunderbolt 4 port for up to four 4K displays. It also provides four USB-A and two USB-C ports for peripherals. Not suited for buyers who require more than four video outputs or need a dock without an external power brick.

280 W power adapter with 230 W laptop charging

The single specification that decides fit is the 280 W AC adapter delivering up to 230 W to the host laptop via the combo cable. If your workstation requires that power level and uses Thunderbolt 4 or USB-C Alt Mode, this dock matches; if your device charges only through a proprietary barrel jack or needs less than 100 W USB-C PD, a smaller adapter may be sufficient.

Questions about this item

How do I confirm the Thunderbolt 4 dock is delivering 230 W to my laptop after setup?

Connect the HP combo cable to the Thunderbolt 4 port; the dock supplies up to 230 W (100 W USB-C plus 130 W Smart Pin) and Windows will show the charging rate in battery settings.

What cables and adapters come in the box versus what I must buy separately?

The package includes the 280 W AC adapter, the HP combo cable for host connection, and a Dockztorm USB hub; no extra video or Ethernet cables are supplied.

Which version should I choose for four 4K 60 Hz monitors — the HDMI 2.0, DisplayPort 1.4 or Thunderbolt 4 outputs?

Use the two DisplayPort 1.4 ports and the Thunderbolt 4 port for three native 4K 60 Hz streams; add the HDMI 2.0 port for a fourth display when the host supports quad-head output.
