UGREEN CM251 5-in-2 Dual USB-C Mac Docking Station – 3× USB 3.0, 4K HDMI & 100W PD
Modern MacBooks offer excellent performance but often leave you with limited connectivity. The UGREEN CM251 5-in-2 Dual USB-C Mac Docking Station solves that problem by expanding two USB-C ports into a convenient workstation with three USB-A 3.0 ports, 4K HDMI output and USB-C Power Delivery pass-through charging.
Designed specifically for compatible MacBook Air and MacBook Pro models with two adjacent USB-C/Thunderbolt ports, the CM251 connects directly to your MacBook without a separate dangling hub cable.
Whether you're connecting an external monitor, transferring files from a USB drive, using a mouse and keyboard, or charging your MacBook, the CM251 brings your essential connections together in one compact adapter.
Key Features
3× USB-A 3.0 Ports – Expand Your Connectivity
Add three full-size USB-A ports to your compatible MacBook. The USB 3.0 ports support data transfer speeds of up to 5Gbps, making them suitable for external drives, USB flash disks, keyboards, mice, printers and other peripherals.
4K HDMI – Connect an External Display
Connect your MacBook to an HDMI monitor, television or projector with support for up to 4K UHD resolution at 3840×2160 @ 30Hz. This makes the CM251 useful for office work, presentations, media consumption and extending your workspace.
100W USB-C PD Pass-Through Charging
The USB-C port supports up to 100W Power Delivery pass-through charging, allowing you to connect a compatible USB-C charger while continuing to use the hub's other ports. The actual power delivered to the MacBook depends on the connected charger and the MacBook's charging requirements.
Dual USB-C Direct-Insertion Design
Unlike conventional hubs with a long connecting cable, the CM251 uses two USB-C male connectors that plug directly into two adjacent USB-C ports on compatible MacBooks. This creates a cleaner setup with less cable clutter.
Designed for Compatible MacBook Models
The CM251 is designed around MacBook models with the required dual USB-C/Thunderbolt port arrangement. It is particularly suited to compatible MacBook Air and MacBook Pro models.
Ideal For
The UGREEN CM251 is particularly useful for:
- MacBook users who need additional USB-A ports

- Content creators working with external USB storage
- Presentations using an HDMI projector or display
- Work-from-home setups requiring a cleaner desktop connection

Important Compatibility Note
The CM251 is not a universal USB-C hub. Its dual USB-C male connectors are designed to plug into two adjacent USB-C ports on compatible MacBook models. Before purchasing, confirm that your MacBook has the required port arrangement.
Also, the 100W figure refers to PD pass-through capability, not necessarily 100W being delivered directly to the MacBook in every setup.
