UGREEN 25851 USB 3.0 4-Port Hub is in stock now at Mascom International for KSh 1,300, splitting a single USB-A port on your computer into four USB-A ports rated at 5Gbps. The UGREEN 25851 carries UGREEN's CM219 model code, arrives brand new and sealed, and attaches through a short 15cm built-in cable. Collect the UGREEN 25851 USB 3.0 4-Port Hub at Mascom International, Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD. Every port on the UGREEN 25851 accepts keyboards, mice, flash disks, printers, webcams, and wireless receivers with no driver install and no software setup required.
Kenya's accountants, university students, graphic designers, and small-business owners keep hitting the same wall: a thin laptop with two USB-A ports and four things that need plugging in. A wireless mouse receiver claims one. A flash disk claims the other. Then the printer cable, the webcam, and a client's external drive have nowhere to sit, so the afternoon disappears into swapping cables mid-task. The UGREEN 25851 USB 3.0 4-Port Hub removes that swapping for KSh 1,300, which costs less than a week of matatu fare between Rongai and town.
Unlike other electronics retailers in Kenya, Mascom International stocks the genuine UGREEN 25851 rather than the unbranded look-alikes that start dropping connections after three months. Users consistently report that the 33g shell disappears into a laptop sleeve and that the indicator light makes a dead host port obvious in seconds. At Mascom International, we're seeing steady demand from Nairobi CBD offices running older desktop towers beside newer thin laptops. Walk into our Kimathi Street store Monday through Saturday to test the UGREEN 25851 on your own machine before paying, or order it for pay-on-arrival delivery anywhere in Kenya.
Common Questions About the UGREEN 25851 USB 3.0 4-Port Hub
What does the UGREEN 25851 USB 3.0 4-Port Hub actually do?
It turns a single USB-A port into four working USB-A ports, so four devices run at the same time from one connection. The UGREEN 25851 draws its power from the computer itself through the built-in cable, meaning no wall socket and no adapter block on your desk. Plug it into a laptop, a desktop tower, or a compatible PlayStation or Xbox console, and the four ports become available immediately. It handles keyboards, mice, wireless dongles, flash disks, printers, webcams, card readers, and USB microphones.
How fast is data transfer through the UGREEN 25851?
Each port runs at USB 3.0 speed, up to 5Gbps, which is roughly ten times the 480Mbps ceiling of USB 2.0. UGREEN rates a 10GB file copy at about 16.4 seconds under good conditions, though your actual figure depends on the flash disk or drive you connect. The hub stays backward compatible with USB 2.0 and USB 1.1 hardware, so an old office printer still works, just at its own slower rate. Bandwidth is shared across the four ports during simultaneous heavy transfers.
Which computers and consoles work with the UGREEN 25851?
Any device with a standard USB-A port works, including Windows laptops, desktop towers, MacBooks that still carry USB-A, Linux machines, and Chromebooks. The UGREEN 25851 also adds ports to PlayStation and Xbox consoles for controllers, headsets, and external game drives. Newer ultrabooks with only USB-C ports need a separate USB-C to USB-A adapter, which Mascom International stocks. Older HP EliteBook, Dell Latitude, and Lenovo ThinkPad units common across Kenyan offices all take it directly with nothing extra.
Do I need drivers, software, or a power adapter?
None of the three. The UGREEN 25851 is plug and play on Windows, macOS, Linux, and ChromeOS, with the operating system recognising it within a second or two of connection. There is no installation disc, no download, and no account to create. It is bus-powered, drawing what it needs from the host computer, so no wall socket is involved and no power brick sits on your desk. A small indicator light confirms the connection is live.
Can the UGREEN 25851 charge my phone or power a hard drive?
No, it is built for data rather than charging. UGREEN caps the combined draw of everything connected at 900mA, which covers keyboards, mice, dongles, flash disks, and webcams comfortably. A phone plugged in will trickle at best and may not charge at all. Bus-powered 2.5-inch portable drives generally run fine, and UGREEN states two 1TB units can operate together. Desktop 3.5-inch drives with their own mains adapters also work, since they draw nothing from the hub.
What is the difference between this hub and a USB-C docking station?
Price and scope. The UGREEN 25851 costs KSh 1,300 and does one job: more USB-A ports. A docking station starts around KSh 6,000 and adds HDMI video output, Ethernet, an SD card slot, and laptop charging through a single cable. If your machine already has HDMI and a network port and you simply ran out of USB sockets, this hub is the sensible spend. If you drive dual monitors daily, choose the dock instead.
Why choose the UGREEN 25851 over a cheaper unbranded hub?
Unbranded hubs sold around KSh 400 to KSh 700 in Kenya commonly use weak controller chips that drop connections whenever two devices get busy, and their solder joints fail within months. The UGREEN 25851 uses a proper USB 3.0 controller, an ABS shell, and moulded cable strain relief. Buyers across Kenya report it holding connection through full working days without random dropouts. Mascom International backs it with a written warranty and a physical service desk in Nairobi CBD.
How does the UGREEN 25851 handle daily transport in a laptop bag?
The whole unit weighs about 33g and measures around 10mm thick, so it slips into a laptop sleeve pocket without adding noticeable bulk. The 15cm built-in cable is short by design, keeping the hub tucked beside the machine rather than trailing across the desk. The ABS shell shrugs off the dust common on Thika Road and Mombasa Road commutes, though it carries no water resistance rating. Wipe it with a dry cloth and keep it out of rain.
Technical Specifications
Data Transfer and USB Standard
- USB 3.0 specification, also labelled USB 3.2 Gen 1, carries up to 5Gbps per connected device
- Roughly ten times quicker than USB 2.0 at 480Mbps, cutting long file copy waits substantially
- UGREEN rates a 10GB file copy at about 16.4 seconds with matching drive hardware attached
- Backward compatible with USB 2.0 and USB 1.1 peripherals, covering older printers, scanners, and keyboards
- Total bandwidth is shared, so four simultaneous heavy transfers each run below the headline 5Gbps figure
- Real-world speed also depends on the host machine's own USB controller and the connected storage
Port Layout and Host Connection
- One USB-A 3.0 male connector on a built-in cable plugs into the host computer directly
- Four USB-A 3.0 female ports sit in a single row along one edge of the body
- Ports are spaced to take standard flash disks without blocking the neighbouring socket beside them
- Built-in cable measures about 15cm, keeping the hub close beside a laptop rather than trailing
- No video output, Ethernet, or card reader on board; this unit expands USB-A connections only
Operating System and Device Compatibility
- Windows 11, Windows 10, and older Windows builds recognise the hub with no driver download
- macOS on Intel and Apple silicon MacBooks with USB-A ports works straight out the packaging
- Linux distributions including Ubuntu and Fedora mount connected devices through native kernel support
- ChromeOS on Chromebooks handles the hub natively, useful for school and college machines countrywide
- PlayStation and Xbox consoles accept it for controllers, headsets, and external game storage drives
- USB-C-only laptops need a separate USB-C to USB-A adapter, stocked at Mascom International
Power Limits and Storage Drive Support
- Bus-powered from the host port, requiring no wall adapter and no separate mains cable
- Combined current draw across all four ports should stay under 900mA per UGREEN guidance
- Not built for phone or tablet charging; a connected phone may trickle slowly or not at all
- UGREEN states two bus-powered 1TB 2.5-inch portable drives can run together on the hub
- Desktop 3.5-inch drives with their own mains adapters connect without loading the hub at all
- High-draw hardware such as USB fans, lights, and heated cups belongs on a dedicated port
Build Quality and Portability
- ABS plastic shell in black with a painted metallic finish that resists scuffs inside bags
- Weight of roughly 33g adds almost nothing to a daily laptop bag or student backpack
- Thickness of about 10mm, near 0.4 inches, slides into a laptop sleeve pocket easily
- Moulded strain relief where the cable meets the body reduces the usual breakage point
- Stays cool through long sessions with all four ports occupied, according to user reports
- No water or dust rating, so keep it dry during Nairobi's March and October rains
Setup, Indicators, and Daily Handling
- Plug into any free USB-A port; connected devices are recognised within a second or two
- Single indicator light confirms power and connection, making a dead host port obvious immediately
- Hot-swapping is supported; eject storage properly through the operating system before pulling it out
- No configuration app, firmware update, or account registration is required at any stage
- Suits fixed desks, matatu commutes, hot-desking offices, and cyber cafes where hardware changes hands often
Package Contents
The UGREEN 25851 USB 3.0 4-Port Hub retail packaging from Mascom International contains the hub itself with its integrated USB-A cable already attached, plus the UGREEN user manual and warranty documentation. No power adapter, no loose cable, and no driver disc are included, because none of the three are needed for normal use. Mascom International stocks USB-C to USB-A adapters, USB extension cables, and mains-powered USB hubs separately for buyers whose laptops carry only USB-C ports or who need higher current.
Warranty
The UGREEN 25851 USB 3.0 4-Port Hub carries a 6-month Mascom International warranty on manufacturing defects under normal use. Cover runs on the hub body, the integrated cable, and the four ports. Physical damage, liquid damage, and failures caused by connecting hardware above the 900mA limit fall outside cover. Our Nairobi CBD service desk processes claims directly.
