UGREEN CM888 7-in-1 UNO Docking Station – USB-C, 2× USB 3.0, Gigabit Ethernet, 4K HDMI & 100W PD

Turn one compatible USB-C port into a complete workstation with 4K HDMI, Gigabit Ethernet, USB expansion and up to 100W Power Delivery.

Turn Your USB-C Laptop Into a Complete Workstation

Modern laptops are thinner and more portable than ever, but that convenience often comes with fewer built-in ports.

If you've ever needed to connect an external monitor, wired internet, USB accessories and your laptop charger at the same time, you already know how quickly limited ports can become a problem.

The UGREEN CM888 7-in-1 UNO Docking Station gives you a practical way to expand your compatible USB-C laptop with the connections you need for work, entertainment and everyday productivity.

It combines USB-C, two USB 3.0 ports, USB-A 2.0, Gigabit Ethernet, 4K@60Hz HDMI and 100W Power Delivery into one compact docking station.

Instead of carrying several individual adapters, connect your essential peripherals to the CM888 and use a single USB-C connection to your laptop.

Key Features

Gigabit Ethernet – Faster, More Stable Wired Networking

Wi-Fi is convenient, but a wired network connection can provide greater stability for demanding online activities.

The built-in RJ45 Gigabit Ethernet port supports network speeds of up to 1000Mbps on compatible networks.

Connect your laptop directly to a wired network for:

• Video conferencing
• Large file transfers
• Cloud applications
• Remote work
• Online gaming
• Streaming
• Office networks
• Reliable internet access

This makes the CM888 particularly useful for home-office users and professionals who prefer a wired connection over Wi-Fi.

Actual network speeds depend on your internet connection, router, network equipment and other conditions.

4K@60Hz HDMI – Expand Your Screen

Connect your compatible USB-C laptop to an external display through the HDMI port.

The CM888 supports up to 4K@60Hz, giving you a detailed and smooth external display experience when paired with compatible hardware.

Use it with:

• 4K monitors
• TVs
• Projectors
• External displays

An additional screen can make everyday tasks more efficient by giving you more room for documents, spreadsheets, browsers, communication tools and other applications.

It's particularly useful for:

Office work → Presentations → Home offices → Content consumption → Creative workflows

Important HDMI Compatibility

Your laptop's USB-C port must support DisplayPort Alt Mode or another compatible video-output technology for HDMI functionality to work.

A USB-C port designed for data and charging only may not support external video.

2× USB 3.0 – Connect Your Everyday Accessories

The CM888 includes two USB-A 3.0 ports for connecting your existing USB accessories.

USB 3.0 provides data transfer speeds of up to 5Gbps with compatible devices.

Connect:

• External hard drives
• USB flash drives
• External SSDs
• Keyboards
• Mice
• Printers
• USB accessories
• Other compatible peripherals

This gives you convenient access to traditional USB-A connectivity even when your laptop has moved almost entirely to USB-C.

Actual data speeds depend on the connected device, cable and host computer.

USB-C 3.0 – Connect Modern USB-C Accessories

The dedicated USB-C 3.0 data port allows you to connect compatible USB-C peripherals without sacrificing your laptop's main USB-C connection.

Use it for compatible:

• USB-C storage
• External SSDs
• Smartphones
• USB-C accessories
• Other USB-C data devices

This combination of USB-A and USB-C connectivity makes the CM888 suitable for both older peripherals and newer USB-C accessories.

USB-A 2.0 – Perfect for Low-Bandwidth Peripherals

The additional USB-A 2.0 port provides convenient connectivity for everyday peripherals that don't require high-speed data transfer.

It's well suited for devices such as:

• Keyboard
• Mouse
• Printer
• USB receiver
• Basic USB accessories

This leaves the faster USB 3.0 ports available for devices that benefit from higher transfer speeds.

100W USB-C Power Delivery – Charge While You Work

The UGREEN CM888 supports up to 100W USB-C Power Delivery, allowing you to connect your compatible USB-C charger to the docking station while using the hub's other ports.

This is especially convenient for laptops with limited USB-C ports.

Your setup can be as simple as:

USB-C charger → CM888 → Laptop

While the hub is connected, you can simultaneously use your:

Monitor + Ethernet + USB accessories

without repeatedly disconnecting your laptop charger.

Important

The 100W specification refers to the maximum Power Delivery capability. Actual charging power received by your laptop depends on the laptop, charger, USB-C cable and power requirements of the connected devices.

Build a More Productive Home Office

The CM888 is particularly useful as the central connection point for a home or office workstation.

Connect your:

4K monitor
Gigabit Ethernet
Keyboard
Mouse
External storage
USB accessories
Laptop charger

to the docking station.

Then connect one USB-C cable to your laptop.

When you arrive at your desk, you're ready to work.

When you leave, disconnect one cable.

Less plugging and unplugging. Less cable clutter. More productivity.

Important Compatibility Information

Check Your USB-C Port Before Buying

USB-C is a connector type, not a guarantee of specific functionality.

For the CM888's HDMI output to work, your laptop or host device needs a USB-C port that supports DisplayPort Alt Mode or compatible video output.

HDMI Resolution Depends on Your Device

Although the CM888 supports up to 4K@60Hz, the actual resolution and refresh rate depend on your laptop, graphics hardware, USB-C implementation, HDMI cable and connected display.

USB Transfer Speeds Vary

The advertised USB speeds represent maximum theoretical capabilities under compatible conditions.

Your actual transfer speed can be affected by the connected storage device, cable, host computer and operating system.

100W PD Is Maximum Input Capability

The docking station can accept up to 100W USB-C Power Delivery, but the laptop's actual charging power may be lower.

Why Buy the UGREEN CM888 7-in-1?

The biggest advantage of the CM888 is that it combines high-value workstation connectivity into one compact device.

You get:

USB-C + 2× USB 3.0 + USB-A 2.0 + Gigabit Ethernet + 4K@60Hz HDMI + 100W PD

That means you can connect your:

Monitor + wired internet + keyboard + mouse + storage + charger

through one docking station.

For a modern USB-C laptop, this can transform a limited-port device into a much more capable desktop workstation.
