USB A extension cable with amplifier, UGREEN US121, 10 m, black, A plug to A socket

UGREEN US121 is a 10 m USB A extension cable with an integrated amplifier that extends USB A connections while maintaining signal quality. Designed for USB 2.0 devices, the cable uses gold-plated contacts and a straight A plug to A socket configuration in black, enabling longer reach for peripherals without frequent connection loss. The amplifier compensates signal degradation over distance to support reliable data transfer and device operation in home and office environments.

Advantages

The built-in signal amplifier preserves data integrity over the 10 m run, reducing errors and disconnections. Gold-plated contacts improve corrosion resistance and contact reliability. The cable’s USB A plug to USB A socket layout provides plug-and-play compatibility with a wide range of USB 2.0 peripherals. Its 10-m length allows flexible device placement without the need to relocate host equipment.

Suitable for

• Connecting external hard drives and flash storage at a distance from the host computer
• Extending keyboard and mouse connections for desktop setups
• Placing printers or scanners further from the workstation
• Positioning webcams and conferencing devices for better coverage
• Temporary workstation layouts in offices, classrooms or meeting rooms

Key specifications

• Cable length: 10 m
• Connector type: USB A plug to USB A socket
• USB standard: USB 2.0
• Contact plating: Gold-plated contacts
• Signal boosting: Integrated amplifier to compensate for cable loss
• Colour: Black

How to use

Plug the USB A plug into the host computer or powered USB hub and insert the USB A socket end to the peripheral device. Ensure connectors are fully seated to make proper contact with the gold-plated contacts. No special drivers are required for typical USB 2.0 devices; the amplifier is passive/active as designed to maintain signal levels automatically. For best results, avoid tight bends near the connectors and keep the cable away from high-power electrical sources that may cause interference.

Recommendations

Use this cable to extend USB 2.0 peripherals up to 10 m where maintaining stable data transfer is important. For high-bandwidth devices that require USB 3.x speeds, consider using a suitable USB 3.x active extension cable or a shorter direct connection. Inspect connectors for dirt or damage before use and route the cable to minimize strain and electromagnetic interference.
