UGREEN US121 USB 2.0 Active Extension Cable 30M | Triple-Shielded, FE1.1s Booster Chipset, 480Mbps Type-A
Bridge an entire warehouse aisle, classroom block, or parking compound between your PC and the equipment sitting at the other end — stocked today on Kimathi Street
Condition: New
Note: price and availability are subject to change without prior notice
UGREEN US121 30M is now in stock at Mascom International for KSh 8,300, carrying a built-in FE1.1s chipset that rebuilds the USB 2.0 signal and moves data at up to 480Mbps across a full 30 metres. The US121 ends in a standard Type-A male plug on the computer side and a Type-A female port on the device side, so it drops into an existing setup without converters. Mascom International holds the UGREEN US121 30M brand new and sealed in UGREEN retail packaging at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD.
Godown supervisors in Industrial Area, fuel station managers, car yard security teams, and farm operators in Naivasha and Nyandarua share one headache: the computer is in the office and the equipment is 25 metres away, past a loading bay or across an open yard. Moving the PC is not an option, and running a second machine out there costs far more than a cable. The UGREEN US121 30M closes that distance in one continuous length, with no powered hub, no repeater box bolted to a wall, and no software to configure on either end.
Unlike other electronics retailers in Kenya who stock unbranded 30-metre USB leads with no published chipset or conductor gauge, Mascom International carries the genuine UGREEN US121 30M with tin-plated copper conductors and triple screening. Technicians consistently report that unbranded long leads work for a week, then start dropping the device at random, turning a finished job into three return visits. The UGREEN US121 30M costs KSh 8,300 once. Bring your own camera or barcode terminal to our Kimathi Street counter and watch it hold across the full 30 metres, or order for pay-on-arrival delivery to any of Kenya's 47 counties.
Common Questions About the UGREEN US121 30M
Why choose the 30-metre length over the 25-metre version?
Buy on the maths, not the label. The 25-metre US121 sells for KSh 7,000, or KSh 280 a metre. The 30-metre costs KSh 8,300, and those extra five metres work out at KSh 260 each — cheaper per metre than the shorter cable. More to the point, a run that lands one metre short is worthless, and a second site visit plus a replacement cable costs several times the KSh 1,300 difference. Measure the route, add slack, then size up.
Is 30 metres the longest a single USB 2.0 cable can span?
For an active cable of this design, yes. USB 2.0 sets a ceiling on how many repeaters can sit in a chain, and a 30-metre boosted run already uses that headroom. This is why UGREEN builds the US121 up to 30 metres and stops there. Anything longer needs a different technology altogether, such as a USB-over-Ethernet extender pair. Within the 30 metres the cable behaves as one uninterrupted lead, so nothing needs mounting or powering at the halfway point.
Which Kenyan sites genuinely need the full 30 metres?
Godowns and logistics yards where the office sits at one end and the goods-in scanner at the other. Fuel stations linking a forecourt camera to the back-office PC. Car yards, greenhouses, and poultry units where a monitoring lens watches a gate or a shed 25 metres out. Auditoriums and school halls placing a presenter camera at the stage while the laptop sits at the technical desk. Construction site offices reaching a container store across an open compound.
How much slack should I leave, and can I shorten the cable?
Leave two to three metres of slack and coil the excess neatly at the equipment end. Never cut this cable to length. The FE1.1s chip and the four-core structure depend on the factory terminations at both ends, so cutting and rejoining destroys the boosted circuit and ends warranty cover. If the route is 22 metres, the 30-metre lead still works fine with the surplus coiled in a loop of at least 20 centimetres diameter, tied loosely rather than kinked tight.
Will mains wiring or motors interfere across this span?
Triple screening handles most of it. A foil wrap, a braid layer, and a ground drain sit around the conductors, rejecting the electrical noise thrown off by fluorescent fittings, compressor motors, welding sets, and mains runs sharing a cable tray. The four-core structure also keeps the power pair away from the data pair. Where you have a choice, cross mains cable at right angles rather than running alongside it, and keep at least 30 centimetres between the two.
My device keeps dropping out at the far end what now?
Work through it in order. First check current draw: an external drive, some printers, and certain wireless adapters need a 5V 2A DC supply feeding the extension rather than host power alone. Second, try the device on a short lead at the computer to confirm the device itself is sound. Third, check whether the run passes close to a motor or ballast. Bring the setup to Kimathi Street if it still misbehaves and our counter staff will test it.
What should I check before ordering for an installation?
Measure the true cable path, not the straight-line distance between rooms. Walls, ceiling voids, door frames, and skirting routes typically add 30 to 40 percent over the direct measurement. Confirm your device speaks USB 2.0 or older, since USB 3.0 drives need different hardware. Note whether a mains socket exists near the far end for a DC supply if the device draws heavily. Call our team with those three answers and we will confirm the right length.
What support does Mascom International give after installation?
At Mascom International, we're witnessing more installers buy long USB leads online and lose a full day when the cable fails on site with nobody to call. Our Nairobi CBD counter handles US121 claims directly rather than sending units abroad, and our staff have specified long runs for CCTV, retail, and classroom jobs across the country. Call or WhatsApp +254 708 852 521 before you pull the cable if you want the route checked, and after if anything misbehaves.
Technical Specifications
Thirty-Metre Span and Chip-Level Amplification
- Single continuous 30-metre lead removes the need for hubs, repeater boxes, or powered midpoint hardware
- FE1.1s low-power booster chipset rebuilds the USB waveform in transit so hosts keep recognising the far device
- Low-power chip design keeps the connector shell cool through continuous all-day operation in warm plant rooms
- Amplifier circuitry sits inside the Type-A plug shell, so nothing needs mounting or powering along the route
- Passive USB leads lose usable signal past roughly 5 metres, which is precisely the limit this chip removes
- UGREEN model reference US121, part number 10326, quoted for reordering and warranty claims later
Throughput Rates and Protocol Handling
- USB 2.0 High-Speed rate up to 480Mbps covers webcam video, print jobs, and scanner output comfortably
- Backward compatible with USB 1.1 and USB 1.0 hardware, keeping older industrial and laboratory equipment in service
- Plug-and-play on Windows, macOS, Linux, and ChromeOS with no driver installation and no configuration screens
- Data-only circuit: this lead transfers information and cannot serve as a phone or tablet charging run
- USB 3.0 external drives sit outside what the USB 2.0 standard itself carries, regardless of cable quality
- Four-core internal layout separates the data pair from the power pair to stop crosstalk between them
Conductor Gauge, Screening and Noise Rejection
- Tin-plated copper conductors at 28/24AWG lower transfer impedance so voltage holds across the whole 30 metres
- Triple screening of foil wrap, braid layer, and ground drain rejects EMI and RFI picked up along the route
- Screening matters where cable trays carry mains circuits alongside data, common in Kenyan godowns and plant rooms
- Metal wire braid inside the jacket resists pulling and dragging when technicians haul the run through conduit
- PVC outer jacket stays flexible around corners without kinking, cracking, or splitting at tight bend points
- Cutting or splicing the lead destroys the boosted circuit, so route the surplus as a loose coil instead
Plug Hardware and Insertion Life
- Type-A male plug at the host end fits any standard computer, laptop, DVR, till, or console port
- Type-A female port at the far end accepts an existing device lead or dongle with no further adapter
- Gold-plated contacts rated beyond 10,000 insertion cycles suit shared counters where the female end sees daily use
- ABS connector housings resist abrasion when the run is dragged through ceiling voids and floor ducting
- Moulded strain relief at both ends protects the conductors where the cable flexes hardest under installation load
- Standard connector dimensions clear wall boxes, patch panels, and equipment enclosures without filing or modification
Supported Equipment and Host Platforms
- Printers, scanners, webcams, USB security cameras, barcode terminals, and wireless network adapters all run over the span
- Keyboards, mice, card readers, USB headsets, and loudspeakers work across the full 30 metres without extra hardware
- Game controllers plus VR headsets including Oculus Rift and HTC Vive connect for tethered play at distance
- Xbox 360 Kinect and PlayStation 3 Eye camera modules were among the original targets for this cable design
- Host platforms cover Windows, macOS, Linux, and ChromeOS machines with no vendor software required
- Higher-draw devices may need a 5V 2A DC supply into the cable's power input to stay stable
Site Routing, Weight and Storage
- Black jacket throughout, the single colour UGREEN produces in the US121 30-metre length
- Packaged weight around 1.33kg reflects the copper mass carried across 30 metres of screened conductor
- Retail carton measures roughly 21 x 21 x 7cm with the lead coiled for transport and storage
- Copes with temperature swings across Nairobi offices, Mombasa godowns, and unventilated server cupboards
- Suits ceiling, wall, conduit, and cable-tray routing in yards, halls, retail floors, and workshops
- Add two to three metres of slack when measuring, and coil surplus in loops of 20 centimetres or wider
