UGREEN CM512 6-in-1 USB-C Docking Station – 3× USB 3.0, 4K HDMI, Gigabit Ethernet & 100W PD

Modern laptops increasingly rely on USB-C for connectivity, but a single USB-C port may not provide enough connections for your everyday peripherals. The UGREEN CM512 6-in-1 USB-C Docking Station expands one USB-C connection into a versatile workstation with three USB-A 3.0 ports, HDMI video output, Gigabit Ethernet and USB-C Power Delivery pass-through.

Whether you're working from a home office, connecting an external monitor, transferring files from a USB drive or switching from Wi-Fi to a wired network connection, the CM512 provides the essential ports in one compact adapter.

Key Features

3× USB 3.0 – Expand Your USB Connectivity

Add three full-size USB-A ports to your USB-C laptop or other compatible device.

The USB 3.0 ports support data transfer speeds of up to 5Gbps, making them suitable for external storage, USB flash drives, keyboards, mice, printers and other peripherals.

This makes the CM512 particularly useful for laptops that have moved away from traditional USB-A ports.

4K HDMI – Connect an External Display

Connect your laptop to an HDMI monitor, TV or projector through the CM512.

The HDMI output supports resolutions up to 3840×2160 at 30Hz, making it suitable for office productivity, presentations, video playback and additional screen space.

The host device must support video output through USB-C/DisplayPort Alt Mode for HDMI functionality to work.

Gigabit Ethernet – Reliable Wired Networking

The built-in RJ45 Gigabit Ethernet port provides wired network connectivity at up to 1000Mbps, with support for 10/100/1000Mbps network speeds.

This is particularly useful when Wi-Fi is unreliable or when you need a more stable connection for:

• Video conferencing
  
• Large file transfers
  
• Remote work
  
• Online gaming
  
• Office networks
  
• Streaming
  

100W USB-C PD Pass-Through Charging

The USB-C PD port supports up to 100W Power Delivery pass-through, allowing you to connect your USB-C charger to the hub while using the HDMI, USB and Ethernet ports.

This means you can keep your compatible laptop powered without sacrificing your only USB-C charging connection.

Important: 100W is the maximum PD pass-through capability. The actual charging power delivered to the laptop can be lower depending on the charger, cable, host device and power requirements.

Compact Aluminium Construction

The CM512 uses an aluminium alloy housing designed for everyday portability and durability. Its compact form makes it suitable for a laptop bag, office desk or home workstation.

Ideal For

The UGREEN CM512 is a practical choice for:

• Laptop users who need additional USB-A ports
  
• Office professionals connecting monitors and peripherals
  
• Remote workers who need wired Ethernet
  
• Students using USB accessories and external displays
  
• Home-office setups
  
• Presentations using HDMI projectors
  
• Users with USB-C laptops that lack traditional USB-A and Ethernet ports
  
• Anyone who wants charging, networking, display and USB connectivity from one adapter

Important Compatibility Note

For HDMI output, your laptop's USB-C port needs to support DisplayPort Alt Mode or another compatible video-output standard. A USB-C port that supports data only will not provide HDMI video.

Likewise, 100W PD is pass-through charging, not a guarantee that every laptop will receive 100W.

Why Buy the UGREEN CM512?

The CM512 is best viewed as a workstation expansion hub, rather than simply a USB adapter.

It combines four particularly useful functions:

USB expansion + external display + wired networking + laptop charging

With one connection, you can add:

• 3× USB-A 3.0
  
• 4K HDMI
  
• Gigabit Ethernet
  
• 100W USB-C PD
  
• Up to 5Gbps USB data transfer
  

That makes it especially attractive for laptop users building a home-office or desktop workstation without wanting a large docking station.
