UGREEN CM251 5-in-2 USB-C Hub is available now at Mascom International for KSh 2,800, sold as a complete dual-plug docking adapter with three USB-A 3.0 ports rated at 5Gbps, one 4K HDMI output at 3840x2160 30Hz, and one USB-C female port supporting 100W Power Delivery pass-through charging. The hub uses a dual USB-C male connector arrangement designed to plug directly into the two left-side or two right-side Type-C ports of a MacBook Pro or MacBook Air, eliminating the need for a trailing cable. Stocked in space grey aluminium alloy at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD.
The UGREEN CM251 5-in-2 USB-C Hub targets MacBook owners across Kenya who need to connect external displays, USB peripherals, and chargers without juggling individual dongles. Content creators editing video on M1, M2, M3, and M4 MacBook Air machines, university students at Strathmore and USIU running presentations through HDMI projectors, software developers using external mice and keyboards at iHub-affiliated workspaces, and corporate consultants moving between client offices in Westlands and Upper Hill all share the same problem: limited Type-C ports on modern MacBooks force constant unplugging. The CM251 solves that with one plug-in adapter.
At Mascom International, we are seeing high demand for the UGREEN CM251 from buyers who previously settled for cheap single-port dongles that overheat under HDMI load. Users consistently report that the aluminium shell stays cool during 4K video output and that the dual USB-C connector arrangement holds firmly without wobbling. Unlike other electronics retailers in Kenya stocking generic no-name hubs from grey-market sources, Mascom International ships the UGREEN CM251 in original UGREEN packaging with verified warranty coverage handled directly from our Nairobi CBD service desk.
Common Questions About the UGREEN CM251
Which MacBook models work with the UGREEN CM251 5-in-2 Hub?
The CM251 is designed specifically for MacBook Pro 2016 through 2020 models and MacBook Air 2018 through 2020 models including the M1 variant. The dual USB-C male connectors slot into two adjacent Thunderbolt 3 or Thunderbolt 4 ports on the left or right side of the laptop. Newer MacBook Pro 14-inch and 16-inch models with three USB-C ports may also work depending on port spacing. The hub does not fit MacBooks while a protective case is attached because the dual plugs need a flush connection to the chassis.
How does the 100W Power Delivery pass-through charging work?
The USB-C female port on the CM251 accepts a standard USB-C PD wall charger and passes power through to the MacBook at speeds up to 100W. Plug your existing 67W, 87W, or 96W Apple charger or any compatible USB-C PD adapter into this port, and the MacBook charges at full rated speed while the hub remains connected. The pass-through circuit handles voltage negotiation automatically without manual configuration. This eliminates the need to remove the hub when you want to charge your laptop overnight or during long working sessions.
Can the HDMI port really output 4K resolution to my monitor?
Yes, the HDMI 1.4 port outputs 4K UHD at 3840x2160 resolution and 30Hz refresh rate, suitable for productivity work, document editing, photo viewing, and slide presentations. The 30Hz refresh rate means HDMI is not ideal for fast-paced gaming or high-frame-rate video editing where 60Hz feels noticeably smoother. For 4K at 60Hz or higher resolutions up to 6K, the USB-C female pass-through port supports DisplayPort Alt Mode through a USB-C to DisplayPort or USB-C to HDMI 2.0 cable, depending on what your monitor accepts.
What is the difference between the three USB-A ports?
All three USB-A ports on the UGREEN CM251 are USB 3.0 specification with 5Gbps theoretical transfer speeds, fully backward compatible with USB 2.0 and USB 1.1 devices. Connect external SSDs for video file transfers, plug in wired keyboards and mice for desktop-style typing, attach USB flash drives for client file exchanges, or run wired Ethernet adapters for cabled internet connections in Nairobi offices with patchy Wi-Fi. All three ports operate simultaneously without bandwidth throttling because the hub draws power directly from the MacBook's internal bus.
Does the UGREEN CM251 work with iPads, Samsung tablets, or Windows laptops?
The CM251 is purpose-built for MacBook Pro and MacBook Air models because the dual USB-C male connector geometry matches Apple's port spacing. Other USB-C devices like iPad Pro, Samsung Galaxy Tab S series, Dell XPS, HP Spectre, and Lenovo ThinkPad models typically have one or two USB-C ports with different spacing and will not physically plug in correctly. Buyers with non-MacBook devices should look at single-cable USB-C hubs like the UGREEN CM511 or Revodok series, which Mascom International stocks for cross-platform compatibility.
Why buy the UGREEN CM251 instead of a cheap generic USB-C hub?
The UGREEN CM251 ships with verified UGREEN factory packaging, an aluminium alloy heat-dissipating shell, and a 12-month manufacturer warranty backed by Mascom International. Generic dongles sold in River Road and from anonymous online sellers often use cheap plastic housings that overheat during HDMI output, drop USB-A data connections under load, and lack proper PD negotiation circuits. Users consistently report that UGREEN hubs from Mascom International outlast three or four generic alternatives, making the KSh 2,800 outlay cheaper over two years.
Is the UGREEN CM251 plug-and-play or does it need drivers?
The CM251 is fully plug-and-play on macOS Big Sur, Monterey, Ventura, Sonoma, Sequoia, and the latest macOS versions. No drivers, software installation, or system preferences changes are required. Plug the dual USB-C connectors into your MacBook, attach your monitor, USB devices, and charger, and everything works within seconds. The hub remains powered as long as the MacBook is on, drawing minimal idle power from the bus. macOS recognises connected displays and USB devices automatically through standard Apple drivers.
What if my MacBook is in a protective case or has thick stickers around the ports?
The dual USB-C male connector design needs a flush surface against the MacBook chassis to maintain a stable connection on both ports simultaneously. Thick protective cases, raised port stickers, or aftermarket port covers prevent the hub from seating correctly, causing intermittent disconnects or charging failures. Remove the case before connecting the CM251 for guaranteed performance. Most slim TPU or polycarbonate shells from MacBook accessory brands work without removal, but rugged cases like UAG or Thule will need to come off.
