UGREEN CM639 Docking Station

1. Introduction

Modern laptops are marvels of engineering—thin, light, and powerful. But there’s one thing they lack: ports. If you own a MacBook, Dell XPS, HP Spectre, or any modern ultrabook, you’ve probably experienced the frustration of having only one or two USB-C ports and nowhere to plug in your multiple monitors, USB-A flash drives, external hard drives, or charge your laptop simultaneously.

Enter the UGREEN CM639 Docking Station—a powerhouse 8-in-1 solution that turns one USB-C port into eight professional-grade connections: dual 4K@60Hz HDMI outputs, 4K@60Hz DisplayPort, two USB-C 3.2 Gen 2 ports (10 Gbps), two USB-A 3.2 Gen 2 ports (10 Gbps), and 100W Power Delivery pass-through charging. This UGREEN docking station is the ultimate companion for professionals, creators, and power users who demand the very best in connectivity and performance.

At Calvantech, we’re proud to offer the UGREEN CM639 Docking Station to customers across Kenya who demand genuine, high-quality accessories for their daily workflow.

2. Why You Need the UGREEN CM639 Docking Station

Let’s face it—port scarcity is real. Apple’s MacBook Air and Pro come with just two USB-C ports. The Dell XPS 13 has two or three. HP Spectre? Also limited. When you need to connect dual external monitors, transfer files from multiple drives, plug in peripherals, and charge your laptop simultaneously, you quickly realize that one or two ports just aren’t enough.

The UGREEN CM639 Docking Station solves this problem instantly. It converts one USB-C port into eight powerful connections:

• 2x HDMI ports – Dual 4K@60Hz for stunning multi-display setups

• 1x DisplayPort – 4K@60Hz for additional high-resolution displays

• 2x USB-C 3.2 Gen 2 ports – 10 Gbps for ultra-fast data transfers

• 2x USB-A 3.2 Gen 2 ports – 10 Gbps for legacy devices

• 1x USB-C PD port – 100W pass-through charging for your laptop

Key benefits at a glance:

• 8-in-1 connectivity – More ports than most hubs on the market

• Triple 4K display support – Connect up to three 4K monitors simultaneously

• 10 Gbps SuperSpeed+ USB – Twice as fast as USB 3.2 Gen 1

• 100W Power Delivery – Charge your laptop at full speed while using all ports

• Plug-and-play – No drivers, no setup

• Premium aluminum build – Durable, stylish, and heat-dissipating

• Broad compatibility – Works with MacBooks, Windows laptops, tablets, and more

3. Key Features of the UGREEN CM639 Docking Station

3.1 Triple 4K Display Support – Dual HDMI + DisplayPort

The UGREEN CM639 Docking Station is a display powerhouse. It features two HDMI ports and one DisplayPort, all supporting 4K UHD resolution at 60Hz. This enables seamless multitasking across multiple screens—perfect for:

• Software development – Code on one screen, debug on another, document on the third

• Video editing – Timeline on one monitor, preview on another, effects on the third

• Financial trading – Monitor multiple markets simultaneously

• Presentations – Connect to projectors and displays with ease

• Gaming – Immersive multi-display gaming experiences

Display Configuration Options:

• Single display – Up to 4K@60Hz on any port

• Dual display – 4K@60Hz on both HDMI ports

• Triple display – 4K@30Hz across all three outputs

Important Compatibility Note: Windows systems support MST (Multi-Stream Transport) for triple extended displays. Mac systems support SST (Single-Stream Transport), meaning mirrored displays only (no extended triple display). The DisplayPort also works well for connecting to high-resolution monitors and projectors.

3.2 10 Gbps USB 3.2 Gen 2 Ports – Blazing-Fast Data Transfer

The UGREEN CM639 Docking Station takes data transfer to the next level with USB 3.2 Gen 2 technology. All four data ports—two USB-C and two USB-A—deliver blistering speeds of up to 10 Gbps. That’s twice as fast as USB 3.2 Gen 1 (5 Gbps) and 20 times faster than USB 2.0.

Transfer a 4GB movie in seconds. Back up hundreds of photos in moments. Move massive video files without frustrating delays. The UGREEN CM639 docking station makes waiting for file transfers a thing of the past.

Important: The 10 Gbps USB-C ports support data transmission only and do not support video output or charging.

3.3 100W Power Delivery – Charge at Full Speed

The UGREEN CM639 Docking Station features a dedicated USB-C PD 3.0 port that supports up to 100W input, delivering approximately 85W pass-through to your laptop (with ~15W reserved for the hub’s operation). This means you can:

• Charge a MacBook Pro 15″ to 100% in about 1.5 hours

• Use all other ports simultaneously while charging

• Never choose between charging and connecting again

3.4 Premium Aluminum Build – Durable and Stylish

The UGREEN CM639 Docking Station is crafted from high-quality aluminum alloy with ABS components that not only look premium in its Space Gray finish but also help dissipate heat efficiently during extended use. The integrated USB-C cable (15–20 cm) provides flexibility while maintaining a clean, clutter-free desk.

Measuring approximately 141 × 57 × 16 mm and weighing just 238 g, the UGREEN CM639 Docking Station is compact enough to slip into any laptop bag. It’s the perfect travel companion for digital nomads, hybrid workers, and professionals on the go.
