The UGREEN US121 USB 2.0 Active Extension Cable (10M) is the perfect solution for users needing to extend the reach between their computer and USB peripherals without losing data integrity or speed. Designed with an integrated signal booster chipset, this active cable maintains stable data transfer up to 480 Mbps over a full 10 meters — far exceeding the limits of passive USB cables. It’s ideal for professional setups, conference systems, and long-range device connections across offices and homes in Kenya.
Unlike standard USB extension cables, the UGREEN US121 includes an active chipset near the female connector to amplify and stabilize signals over long distances. This prevents data loss, lag, or dropouts, ensuring consistent performance for printers, cameras, controllers, and other USB 2.0 devices.
For devices that require more power than the computer’s USB port can supply over 10 meters, the US121 includes a Micro USB 5V port for optional external power input. Connecting an external adapter boosts voltage stability, ensuring reliable operation for energy-demanding peripherals like external hard drives, webcams, or USB hubs.
The cable fully supports USB 2.0 Hi-Speed data rates up to 480 Mbps, perfect for tasks such as transferring files, printing documents, or streaming from webcams. It is backward compatible with USB 1.1 and 1.0 devices, making it highly versatile across a wide range of electronics.
Crafted with a premium PVC outer jacket and gold-plated connectors, the UGREEN US121 ensures long-term durability and corrosion resistance. Its robust shielding reduces electromagnetic interference (EMI), maintaining a clean, stable signal over the full 10-meter length — crucial for professional and industrial applications.
Compatible with all major operating systems including Windows, macOS, and Linux, the UGREEN US121 works seamlessly with a variety of USB peripherals such as:
Printers and scanners
Digital cameras and webcams
Keyboards, mice, and game controllers
USB hubs, card readers, and barcode scanners
This makes it an essential accessory for home offices, conference rooms, and event setups in Kenya.
The cable is completely driver-free. Simply plug it into your host device, connect your USB peripheral to the other end, and you’re ready to go. It supports hot-swapping, meaning you can connect or disconnect devices without rebooting your system.
Extending connectivity for USB devices over large rooms or office setups
Connecting webcams or microphones in conference environments
Providing extra reach to printers or scanners located away from computers
Enabling convenient access to hard-to-reach USB ports on desktops or media centers
Suitable for professional video setups or POS systems in retail environments
