UGREEN CM639 8-in-1 Docking Station is now available at Mascom International for KSh 5,700, ready to transform any USB-C laptop into a complete desktop workstation with triple 4K display output, ten-gigabit data ports, and 100W pass-through laptop charging. Walk into our store at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD to test the UGREEN CM639 with your own MacBook, ThinkPad, ZenBook, or Surface device before purchase. The aluminum-alloy hub measures 195mm long and weighs just 238 grams, fitting easily into any laptop bag for hybrid workers who split time between home, office, and client sites across Nairobi.
This UGREEN CM639 is built for Kenya's hybrid professionals who carry slim ultrabooks with limited port selection. Software developers running dual external monitors plus an external SSD, architects connecting projectors and CAD drives during client presentations, accountants juggling extended spreadsheets across three screens during audit season, and content creators offloading 4K footage from external drives all hit the same wall: laptops with two or three USB-C ports cannot do this work natively. The UGREEN CM639 solves that gap with one cable, replacing four or five separate dongles with a single aluminum hub that handles displays, storage, peripherals, and charging together.
Unlike other electronics retailers in Kenya selling generic unbranded hubs that overheat or lose signal during long sessions, Mascom International stocks the UGREEN CM639 with full manufacturer backing and Nairobi-based warranty processing. Users consistently report the CM639 maintains stable 4K@60Hz output across both HDMI ports for full eight-hour workdays without dropouts, with the aluminum casing dissipating heat well during continuous load. Order the UGREEN CM639 8-in-1 Docking Station today through our store, phone line, or website for next-business-day delivery to Nairobi, Mombasa, Kisumu, Nakuru, and Eldoret addresses.
Frequently Asked Questions About the UGREEN CM639
What devices is the UGREEN CM639 compatible with?
The UGREEN CM639 works with any laptop, tablet, or phone that has a USB-C port supporting DisplayPort Alt Mode and Power Delivery. Confirmed compatible devices include MacBook Pro and MacBook Air (M1, M2, M3, M4), iMac, iPad Pro and iPad Air with USB-C, Lenovo ThinkPad X1 Carbon and X13, HP EliteBook x360 and ProBook, Dell XPS, ASUS ZenBook, Microsoft Surface Pro and Surface Laptop, and most Chromebooks. The integrated USB-C cable connects directly without requiring additional adapters or drivers on Windows, macOS, ChromeOS, or Linux systems.
Does the UGREEN CM639 actually support triple 4K displays?
Yes, but with one important caveat. On Windows laptops with MST (Multi-Stream Transport) support, the UGREEN CM639 drives three separate 4K@60Hz displays through both HDMI ports and the DisplayPort simultaneously, giving you fully extended desktop space across three monitors. On macOS systems, Apple's hardware limits external displays to mirror mode (Single-Stream Transport), so MacBooks see the same image duplicated across all connected screens. MacBooks with M1 Pro, Max, or Ultra chips handle dual extended displays, while base M1/M2/M3 MacBook Air supports only one external display regardless of dock capability.
How much power does the CM639 actually deliver to my laptop?
The UGREEN CM639's 100W USB-C PD port accepts up to 100W input from your laptop charger and passes through 85W to your connected laptop, with the remaining 15W reserved for running the dock and connected peripherals. That 85W is enough to charge a 16-inch MacBook Pro M3 Max during light office work, fully power any 14-inch ultrabook including the ThinkPad X1 Carbon and HP EliteBook, and keep gaming laptops topped up during non-gaming productivity work. You connect your existing USB-C laptop charger to the dock's PD port, then plug the dock's integrated cable into your laptop one cable to your laptop, full charging maintained.
Will the UGREEN CM639 work with my Samsung phone or iPad for desktop mode?
The UGREEN CM639 pairs well with Samsung DeX-capable phones including the Galaxy S22 through S26 series, Z Fold 4 through Z Fold 7, and Galaxy Tab S series, transforming your phone into a desktop workstation with external monitor, USB keyboard, mouse, and storage drives connected through the dock. iPad Pro with M-series chips and iPad Air M2/M3 also work for connecting external monitors and storage drives, though iPadOS limits multi-window behavior compared to Stage Manager on supported models. Samsung DeX through this dock gives field sales staff and university students a portable desktop setup using only their phone.
What's the difference between the USB-C 3.2 ports and the PD port?
The two USB-C 3.2 Gen 2 ports on the UGREEN CM639 transfer data at 10Gbps but do NOT support video output or charging they are data-only ports for external SSDs, USB-C flash drives, and similar storage peripherals. The separate USB-C PD port handles power delivery only, accepting your laptop charger and passing 85W through to your laptop, with no data transfer or video output capability. Trying to connect a monitor or charger to the wrong port causes confusion for new users remember: HDMI and DP ports drive displays, the dedicated PD port charges your laptop, and the two USB-C 3.2 ports handle storage and peripherals.
How fast does data transfer through the USB ports?
Both USB-A 3.2 Gen 2 ports and both USB-C 3.2 Gen 2 ports run at 10Gbps theoretical throughput, roughly twice the speed of standard USB 3.0 ports found on most laptops and budget docks. In real-world testing, copying a 50GB video project folder from an external NVMe SSD to your laptop's internal drive completes in approximately 90 seconds through the CM639, compared to roughly 3 minutes through a standard 5Gbps USB 3.0 port. Photographers backing up wedding shoots, videographers offloading 4K footage, and editors moving project files between drives benefit directly from the doubled bandwidth.
Is the UGREEN CM639 worth KSh 5,700 compared to cheaper unbranded hubs?
The CM639 sits at the value-tier of UGREEN's docking range, undercutting Thunderbolt 4 docks (typically KSh 18,000-35,000 in Kenya) while delivering full triple 4K output and 10Gbps data ports that KSh 2,000-3,000 generic hubs cannot match. The aluminum heat-dissipating chassis, certified 100W PD passthrough, and 10Gbps data ports across all four data slots justify the price gap over budget alternatives. UGREEN's 24-month international warranty backing and Mascom's 12-month local warranty cover the dock through normal use. For users who need three monitors and high-speed peripheral access, the CM639 represents a strong middle ground between cheap unreliable hubs and expensive Thunderbolt docks.
How do I set up extended displays on my Windows laptop?
Connect the UGREEN CM639's integrated USB-C cable to your laptop, then plug your monitors into the two HDMI ports and the DisplayPort. Windows 10 and 11 automatically detect all three displays. Right-click the desktop, select "Display settings," and arrange the monitors by dragging them into your preferred physical layout. Choose "Extend these displays" from the multi-display dropdown to create independent screen real estate across all three monitors. Set each monitor's resolution to 3840x2160 at 60Hz for full 4K output. If only two displays appear, verify your laptop's GPU supports MST output Intel UHD graphics from 11th-gen onwards and AMD Radeon graphics from 6000 series onwards both support triple display through this dock.
