Product overview
Overview
A clear view of the product before you connect it
This model combines the core connections of a mobile workstation in one compact aluminium dock. It provides one HDMI display output, four high-speed USB data connections across USB-C and USB-A, wired Ethernet, two memory-card formats and a dedicated charging input.
The HDMI port supports up to 4K at 60Hz when the host USB-C port, operating system, HDMI cable and display all support that mode. The data ports are listed up to 5Gbps theoretical and the RJ45 network port up to 1000Mbps. Actual performance is limited by the host and connected equipment.
A compatible 100W PD input can provide up to about 85W to the host with current exact-SKU artwork stating up to 85W output to the host. The host accepts only its supported power level, and the charger and cable must provide the required profile.

1 × USB-C PD input
Accepts up to 100W for negotiated host charging, with about 85W maximum stated for the host.
SMOOTH 4K DISPLAY
Connect one HDMI screen at up to 4K 60Hz
The HDMI output supports a single external display for presentations, creative work, spreadsheets, video playback and an extended desktop. A 60Hz refresh rate can provide smoother cursor and motion handling than a 30Hz 4K connection.
Reaching 4K60 requires an end-to-end compatible path: the host USB-C port must output DisplayPort video, the operating system and GPU must expose the mode, and the HDMI cable and display must support it.
- One HDMI display
- Up to 3840 × 2160 at 60Hz
- Mirror or extend where supported
- Compatible HDMI audio
- No second video output
USB-C AND USB-A DATA
Use four peripherals without choosing one connector generation
Two USB-C and two USB-A data ports support compatible flash drives, SSDs, hard-drive enclosures, card readers, keyboards, mice, printers and other accessories. Each can negotiate up to a 5Gbps theoretical link with compatible equipment.
All active devices share the host connection's bandwidth and available power. Simultaneous transfers do not each receive a separate 5Gbps channel, and high-power storage can require PD power to remain stable.
- Two USB-C data ports
- Two USB-A data ports
- Up to 5Gbps theoretical
- Shared upstream bandwidth
- Safely eject storage
NETWORK, CARDS AND CHARGING
Keep a desk connected without relying on Wi-Fi
Gigabit Ethernet provides a wired link for conferencing, file access and managed networks. The SD and microSD slots simplify camera-media transfer, while the PD input can keep a compatible host charged during the same workflow.
A 100W input can provide up to approximately 85W to the laptop according to the exact-SKU artwork; remaining input supports dock operation and conversion overhead. Network and charging results still depend on the router, cable, charger and host.
- 10/100/1000Mbps Ethernet
- SD and TF/microSD readers
- Up to 100W PD input
- About 85W maximum host charging
- Charger and cables not confirmed as included

- Do not expect multiple devices to each sustain their independent maximum speed.
Safe operation
Warnings and limitations
Safety note 1
Mild warmth is normal when high-speed data, HDMI and PD charging operate together. Stop use if heat, smell, noise or physical damage is abnormal.
Safety note 2
Power-hungry peripherals can exceed the available bus power. Connect suitable PD power, reduce devices or use independently powered storage.
Safety note 3
A network link can be 1Gbps while internet speed remains lower because the service, router and remote server set their own limits.
Safety note 4
A 4K60 blank screen commonly indicates host video capability, cable bandwidth, display input or unsupported system settings.
Safety note 5
Removing power during a write operation can corrupt files on connected storage or memory cards.
