Thunderbolt 4 Dock with 280W Adapter

The HP Thunderbolt 280W G4 Docking Station connects to a host through a single Thunderbolt 4 or USB-C cable and adds four USB-A ports, two USB-C ports, an HDMI 2.0 output, two DisplayPort 1.4 outputs, and a 2.5 Gigabit Ethernet jack. A 280W AC adapter is included and the dock can deliver up to 230W to compatible HP workstations via the combo cable, plus up to 100W USB-C Power Delivery for other devices. The bundle also includes a portable Dockztorm hub rated for 5 Gbps data sync.

Suits multi-monitor workstations.

This dock targets professionals who need to drive up to four external 4K displays from one connection and require high-wattage charging for a workstation-class laptop. It also provides wired 2.5 Gigabit networking and a Kensington lock slot for physical security. Buyers who only need a single external monitor, low-profile port expansion, or a bus-powered adapter for frequent travel should consider lighter alternatives.

230W charging via HP combo cable decides fit

The single specification that determines compatibility is the 230W power delivery over the proprietary HP combo cable; only laptops that support this charging method can draw the full rated wattage. Other USB-C systems are limited to 100W USB-C Power Delivery, so verifying the host’s charging requirements against this figure is essential before purchase.

Questions about this item

Should I pick the 280 W model or a lower-wattage dock for my workstation?

The 280 W supply drives up to 230 W through the combo cable, covering high-power workstations; a smaller adapter would limit charging to 100 W USB-C only.

What does the 230 W charging figure mean once the dock is on my desk?

It delivers 230 W to compatible HP laptops via the combo cable while simultaneously running four 4K displays and all connected peripherals.

How does the Thunderbolt 4 link cap real-world display and data throughput?

Thunderbolt 4 supports up to four 4K 60 Hz monitors and 5 Gbps data through the included Dockztorm hub, limited by host capability.
