The HP Thunderbolt 4 Dock 280W G4 with Combo Cable (4J0G4AA) is a professional laptop docking station designed for compatible HP business notebooks and mobile workstations that require extensive connectivity and higher charging power.

The USB-C connection supports up to 100W Power Delivery for compatible systems, while the additional barrel connection is used for higher-power host configurations.

Four USB-A ports provide connectivity for keyboards, mice and other peripherals, while the front USB-C 3.2 Gen 2 port supports up to 10Gbps data transfer and 15W accessory power output. The RJ45 Ethernet interface supports 1Gb and 2.5Gb networking, and HP Sure Start helps protect dock firmware integrity. HP also documents selected network and device management functions for supported business systems.

Design & Performance

Thunderbolt 4 Connectivity for Professional Workstations

The HP Thunderbolt Dock 280W G4 provides Thunderbolt 4 connectivity for compatible laptops. A single docking connection gives access to display outputs, USB devices and wired networking. This helps organize a professional workstation with fewer individual laptop connections.

Full Thunderbolt performance depends on the host laptop. Supported USB-C DisplayPort Alt Mode systems may offer reduced functionality or bandwidth. Check the laptop's docking specifications before purchasing.

280W Adapter with Up to 230W Host Power

This model uses a 280W power adapter and a dedicated combo cable. HP specifies up to 230W power delivery to compatible host systems using the combined connection. It is designed for selected higher-power HP mobile workstations.

The 280W rating refers to the dock's power adapter, not the laptop charging output. The actual host power depends on the supported laptop and connection method. Verify your computer's required power rating before ordering.

USB-C and 4.5mm Combo Cable Design

The supplied host connection combines a USB-C connector and a 4.5mm barrel power connector. This arrangement allows supported HP laptops to receive docking connectivity and additional power through a paired cable design. HP specifies a 0.8-meter host cable.

Not every laptop has a compatible barrel charging port. Non-HP laptops may use USB-C functions without the additional barrel power connection. Confirm the exact laptop model and charging connector.

Support for Up to Four External Displays

HP documents support for up to four external monitors on compatible systems. Video connections include two DisplayPort 1.4 outputs, HDMI 2.0 and USB-C video-capable connections. This is useful for multitasking, office dashboards and technical applications.

The supported monitor count, resolution and refresh rate depend on the host graphics hardware and available bandwidth. Four external displays are not guaranteed on every laptop. Review the intended display configuration before purchasing.

USB-A and USB-C Peripheral Connectivity

The dock includes four USB-A ports and a front USB-C 3.2 Gen 2 port. HP QuickSpecs identify two side USB-A ports supporting up to 10Gbps and two rear USB-A ports supporting up to 5Gbps. The front USB-C port supports up to 10Gbps data transfer and 15W power output.

These connections are useful for USB keyboards, mice, external drives and compatible accessories. Port performance depends on the connected device and host. The front USB-C accessory port is separate from the laptop charging connection.

1Gb and 2.5Gb Wired Ethernet

The rear RJ45 Ethernet interface supports both 1Gb and 2.5Gb network connections. It helps compatible laptops access wired office networks without a separate Ethernet adapter. This can be useful for large file transfers and managed business environments.

Actual network performance depends on the switch, cable and connected computer. HP also documents network management capabilities for selected supported systems. Availability varies by laptop configuration.

HP Sure Start Security and Enterprise Management

HP Sure Start provides dock firmware integrity verification and recovery. This helps protect against certain firmware-level changes. It is relevant to organizations managing connected workstations.

HP also documents features including wired vPro management, eTag, PXE Boot, Wake on LAN and MAC address pass-through. These capabilities depend on supported host hardware and configuration. Some features are not available with non-HP laptops.

Compact Cube Design and Physical Security

The docking station has a compact 98 × 98 × 68 mm cube-style housing. Its small footprint makes it suitable for desks with multiple monitors and accessories. A mechanical power button with LED indicator is positioned on top.

A Kensington Standard Lock Slot supports compatible physical security locks. The dock power button operates only with supported HP notebook systems. This should be considered when using the dock with other laptop brands.

Who It's For

The HP Thunderbolt 4 Dock 280W G4 with Combo Cable is suitable for HP mobile workstation users, engineers, designers, business professionals, office IT departments and technical teams that require multiple monitors, wired networking and extensive peripheral connectivity. Its main advantage is the combined USB-C and 4.5mm barrel power connection, which supports up to 230W host power for compatible higher-performance HP laptops. It is also relevant to users who need Thunderbolt 4 connectivity and a compact desk setup, although charging, display and enterprise management features vary by host computer. Buyers should verify their laptop's Thunderbolt support, barrel charging connector, power requirements and external display capabilities before purchasing.

Simple Buying Guide

Before buying the HP Thunderbolt 4 Dock 280W G4 (4J0G4AA), confirm whether your laptop supports Thunderbolt 4 or the required USB-C docking features. If you need higher-power charging, verify that your HP laptop supports the combined USB-C and 4.5mm barrel connection. Check the number and resolution of external monitors you plan to use, as well as the available DisplayPort, HDMI, USB and Ethernet ports. Compare the 280W version with the 120W G4 model to choose the correct charging configuration for your workstation.
