Turn One USB-C Port Into a High-Speed Workstation
Modern laptops are getting thinner, lighter and more portable, but that often comes at the expense of built-in connectivity.
The UGREEN CM888 6-in-1 UNO USB-C Docking Station gives you a simple way to expand a compatible USB-C laptop, tablet or other device with four high-speed USB data ports, HDMI display output and USB-C Power Delivery.
Unlike basic USB-C hubs that limit you to slower USB connections, the CM888 features two USB-A 3.2 Gen 2 ports and two USB-C 3.2 Gen 2 ports, all designed for data transfer speeds of up to 10Gbps.
Connect external SSDs, USB drives, keyboards, mice and other peripherals while simultaneously connecting an external 4K display and powering your compatible laptop.
Whether you're building a home-office workstation, transferring large files or simply need more ports on your laptop, the CM888 gives you the connectivity you need without carrying multiple adapters.
Key Features
4× USB 3.2 Gen 2 Ports – Up to 10Gbps Data Transfer
One of the biggest advantages of the UGREEN CM888 is its combination of four high-speed USB data ports.
You get:
2× USB-A 3.2 Gen 2 + 2× USB-C 3.2 Gen 2
The ports support data transfer speeds of up to 10Gbps with compatible devices, making the CM888 particularly useful for users working with large files and high-speed external storage.
Connect devices such as:
- External SSDs
- USB flash drives
- External hard drives
- Smartphones
- Cameras
- Keyboards
- Mice
- Printers
- Other USB peripherals
The two USB-C ports are data-only ports. They do not provide video output or additional USB-C charging functionality.
Actual transfer speeds depend on the connected device, storage media, cable and host system.
4K@60Hz HDMI – Expand Your Screen
Connect your compatible USB-C laptop to an external monitor, TV or projector through the dedicated HDMI port.
The CM888 supports up to 4K resolution at 60Hz, providing sharp images and smoother motion for compatible displays.
This makes the hub suitable for:
- Dual-screen office setups
- Presentations
- Video playback
- Photo editing
- Creative work
- Home-office productivity
- External monitor setups
For HDMI output to work, your laptop or host device must support video output through USB-C/DisplayPort Alt Mode.
A USB-C port that supports data only will not provide HDMI video output.
100W USB-C Power Delivery – Keep Your Laptop Powered
The CM888 supports up to 100W USB-C Power Delivery input, allowing you to connect a compatible USB-C charger to the hub while using your other ports.
The hub reserves power for its own operation, with up to 85W available for charging the connected host device.
This means you can connect:
USB-C charger → CM888 → Laptop
while simultaneously using your USB peripherals and HDMI display.
Actual charging power depends on your laptop, charger, cable and connected peripherals.
Important: The advertised 100W refers to PD input. It should not be interpreted as 100W being delivered directly to the laptop.
High-Speed Connectivity for Modern Workflows
The CM888 is particularly well suited to users who work with large files.
With four 10Gbps USB data ports, you can connect multiple high-speed storage devices and peripherals without relying on older USB 2.0 connectivity.
For example:
Laptop → CM888 → External SSD + USB-C SSD + Keyboard + Mouse + 4K Monitor
This makes the CM888 a strong option for:
- Content creators
- Photographers
- Video editors
- Graphic designers
- Developers
- Business professionals
- Students
- Remote workers
- Power users
Two USB-A + Two USB-C Data Ports
The CM888 gives you flexibility when connecting both traditional USB accessories and newer USB-C devices.

Ideal for existing USB accessories such as:
- Flash drives

Important Compatibility Information
Your USB-C Port Must Support Video Output
The HDMI port requires the host device's USB-C port to support DisplayPort Alt Mode or compatible video output.
If your laptop's USB-C port supports data only, the HDMI output will not work.
The Two USB-C Ports Are Data Only
The two USB-C 3.2 Gen 2 ports are designed for data transfer.
They should not be confused with the dedicated USB-C PD input or a USB-C video-output port.
100W PD Input ≠ 100W Laptop Charging
The CM888 accepts up to 100W PD input, while up to 85W is available for the host device after power allocation.
Your actual charging speed will depend on your laptop and charger.
