2-power Thunderbolt 4 Ultra 280W G6 Dock Replaces DOC0258A

For professionals who demand uncompromising throughput and multi-monitor clarity, the 2-POWER Thunderbolt 4 Ultra 280W G6 Dock consolidates a full workstation into a single aluminium hub. Unlike ordinary USB-C docks that split bandwidth or cap power delivery, this unit maintains a true 40 Gbps Thunderbolt 4 uplink while simultaneously charging the host at up to 100 W and supplying 280 W total to connected peripherals. It is a direct replacement for the DOC0258A, engineered to keep cable clutter minimal and productivity maximal.

• Four USB-A 3.2 Gen 2 (10 Gbps) and one USB-A 2.0 port for legacy devices
• 2.5 Gigabit Ethernet, SD/microSD UHS-II card reader, and combo audio jack
• Kensington lock slot and aluminium chassis for durable, secure deployment

In daily use

Connect a Thunderbolt 4 laptop and instantly gain four video outputs, wired network, fast storage access, and a full set of USB peripherals. The dock drives two 4K monitors at 60 Hz without frame drops, or a single 8K display for ultra-high-resolution workflows. The 100 W host charging keeps the notebook topped up during heavy tasks, while the 280 W adapter powers everything from external drives to high-draw accessories. The front-facing USB-C and USB-A ports are ideal for quick device swaps, and the SD/microSD reader accelerates photo and video offloads.
