The UGREEN US121 USB 2.0 Active Extension Cable 20m is available at Mascom International for KSh 3,800, brand new and sealed. This 20-metre lead links a USB-A male plug on your computer to a USB-A female socket at the far end, moving data at up to 480Mbps. Inside, an FE1.1S booster chip rebuilds the USB signal so it arrives clean after the long trip. The UGREEN US121 USB 2.0 Active Extension Cable installs itself with no driver on Windows, macOS or Linux. Pick it up from our First Floor shop in Old Mutual Building, Kimathi Street, Nairobi CBD, or have it delivered.
Designed for IT technicians, church media teams, lecturers and small business owners, the UGREEN US121 USB 2.0 Active Extension Cable handles jobs a desk-length lead cannot. Think of a webcam above a conference room screen in Kilimani, a Wi-Fi adapter moved to a window to catch a weak router signal, or a printer shared from the next room. A plain copper lead stretched this far fails, because USB 2.0 signals fade after roughly five metres. The repeater chip in this cable solves that, so the device at the end acts as though it were plugged into the computer itself.
Unlike other electronics retailers in Kenya that sell long USB leads with no named chip or brand, Mascom International stocks the genuine UGREEN US121 USB 2.0 Active Extension Cable with a written warranty and clear specifications. Buyers throughout Kenya report that 20 metres is the length that usually covers one room to the next, or one floor to another, without leftover coils. Come test the UGREEN US121 USB 2.0 Active Extension Cable 20m with your own device at our Kimathi Street showroom, or order on WhatsApp and pay only when it reaches your door.
Common Questions About the UGREEN US121 USB 2.0 Active Extension Cable
How much is the UGREEN US121 USB 2.0 Active Extension Cable 20m in Kenya?
The UGREEN US121 USB 2.0 Active Extension Cable 20m sells for KSh 3,800, brand new and sealed, at Mascom International in Nairobi CBD. The price includes the genuine UGREEN lead with its FE1.1S repeater chip, a 6-month warranty from Mascom International and pay-on-arrival delivery to any county. The 5m model is KSh 2,200, so the 20m costs KSh 1,600 more. The 25m is KSh 7,000, a KSh 3,200 jump, which makes the 20m the sensible stop for most room-to-room jobs.
Is the UGREEN US121 USB 2.0 Active Extension Cable 20m enough, or do I need the 25m?
The 20m covers most room-to-room and floor-to-floor runs, while the 25m is for longer routes that wrap around corners or ceilings. Both use the same repeater chip and the same 480Mbps USB 2.0 rate. The 25m costs KSh 7,000, which is KSh 3,200 above the 20m at KSh 3,800. Measure the real path, not the straight line, because cable that follows walls and doorframes needs extra metres. If your measured route comes under 18 metres, save the money and take the 20m.
Can I run the UGREEN US121 USB 2.0 Active Extension Cable 20m through ceilings or outdoors in Kenya?
The UGREEN US121 USB 2.0 Active Extension Cable 20m is an indoor cable, so run it inside ceilings, trunking or conduit rather than across open ground. Nairobi's long rains and the strong sun in places like Garissa and Kitui will wear an exposed jacket over time. Inside a ceiling, keep it clear of mains wiring and fluorescent light fittings to avoid interference. If part of the route must cross a veranda, sleeve that section in PVC conduit. Seal the female socket from dust with tape when it sits unused.
Will a webcam work for church livestreams or Zoom lectures on the UGREEN US121 USB 2.0 Active Extension Cable 20m?
Yes, a standard USB webcam works over the UGREEN US121 USB 2.0 Active Extension Cable 20m, which suits livestreams from a balcony or the back of a hall. Most 1080p webcams are built for USB 2.0, so 480Mbps leaves room to spare. Churches in Nairobi and lecturers at universities such as Kenyatta and JKUAT use this layout to place the camera where the view is best while the laptop stays at the sound desk. Test your webcam with the cable in our shop first if it is a 4K model.
Can the UGREEN US121 USB 2.0 Active Extension Cable 20m bring a Wi-Fi adapter closer to the router?
Yes, moving a USB Wi-Fi adapter on a 20-metre lead is one of the most common uses for this cable. UGREEN lists wireless network cards among the devices the US121 range is built for. Many homes and offices on Safaricom Home Fibre, Zuku or Airtel 5G routers have dead spots in back rooms. Placing the adapter in a hallway or near a window, then running the cable back to the desktop, often turns a weak link into a usable one. No settings change on the computer.
Can I join two UGREEN US121 cables together for a longer run?
Joining two active extensions is not a reliable plan, so buy a single UGREEN US121 USB 2.0 Active Extension Cable in the length you need. Each extra link adds delay and draws more power from the computer's port, and some devices stop responding. UGREEN already makes the US121 in 25m and 30m lengths for longer routes. A single run also means one fewer joint to work loose behind furniture or inside a ceiling. Tell us your exact distance on WhatsApp and we will point you to the right length.
Does the UGREEN US121 USB 2.0 Active Extension Cable 20m need a separate power supply?
For keyboards, webcams, Wi-Fi adapters and printers, the UGREEN US121 USB 2.0 Active Extension Cable 20m runs on power from the computer's USB port. UGREEN pairs its longest US121 runs with a 5V 2A power adapter for devices that draw heavy current. At 20 metres, a device with its own mains supply, such as a printer, is no problem. A bus-powered external hard drive is a different case and may not spin up reliably at this distance. Plug the computer into a UPS so short KPLC outages do not drop the link.
Who should buy the UGREEN US121 USB 2.0 Active Extension Cable 20m, and who should skip it?
Buy it if your device needs to sit in another room, on another floor or across a large office from the computer. Church media teams, lecturers, IT support staff and gamers with a TV across the lounge get good value from it. Skip it if your device sits within a few metres of the computer, because the 5m version at KSh 2,200 does that job. Also skip it for fast external SSD backups, since USB 2.0 caps speed; a short USB 3.0 lead suits those better.
Technical Specifications
Core Function and Data Performance
- Up to 480Mbps over USB 2.0 — fast enough to stream a 1080p webcam feed or send a large print job without stutter.
- FE1.1S repeater chip inside — it rebuilds the fading USB signal, so the far device does not see the distance at all.
- 20 metres of usable reach — typically enough to go from one room to the next or from a ground floor to an upper floor.
- Draws power from the computer — a small amount of current feeds the chip, so you do not need a wall socket at either end.
- Automatic recognition — Windows, macOS and Linux load it on their own, which helps on locked company laptops without admin rights.
Compatibility and Device Support
- USB-A male connector — plugs into the full-size USB port on desktops, laptops, smart TV boxes, game consoles and mini PCs.
- USB-A female connector — takes the standard plug from a webcam, Wi-Fi dongle, printer lead, keyboard, game controller or flash drive.
- Backward compatible with USB 3.0 ports — it runs at USB 2.0 pace, which is all a webcam, keyboard or printer will use anyway.
- Laptops with only USB-C ports — add a USB-C to USB-A adapter at the computer end, and the cable then works as normal.
- Best with self-powered or low-draw devices — printers on mains power and Wi-Fi adapters suit it, while bus-powered hard drives may struggle.
Build and Routing
- Black outer jacket — less visible along dark skirting boards and inside ceilings, and it hides dirt better than a light colour.
- Chip housed within the cable — no separate box sits mid-run to snag on furniture or need its own mounting point.
- Firm moulded plugs — grip the plug rather than the lead when unplugging, and the internal wires last much longer.
- One unbroken length — no mid-run joints, which removes the loose connection that chained cheap leads are known for.
- Indoor-rated jacket — suited to trunking, conduit and ceiling space rather than open ground exposed to sun or rain.
What Comes With Your Purchase
- One UGREEN US121 USB 2.0 Active Extension Cable 20m — the genuine product in UGREEN retail packaging, brand new and sealed.
- 6-month Mascom International warranty — protection against manufacturing defects, with claims handled at our Nairobi CBD service desk.
- Free length check on WhatsApp — send us your route and device, and we confirm whether 20 metres is right before you order.
- Test before you pay — bring your webcam, Wi-Fi dongle or printer lead to Kimathi Street and see it working on the cable.
- Pay-on-arrival delivery — settle the bill only after the cable arrives, whether you are in Kiambu, Eldoret, Nyeri or Malindi.
