USB extension cable UGREEN US103, 3 m, black, USB-A to USB-A

UGREEN US103 is a 3 m USB extension cable in black designed to extend existing USB-A connections. This passive cable provides a direct connection between a host and a device without the need for drivers or additional power. The cable supports common USB peripherals such as keyboards, mice, printers and external drives, offering increased reach with standard USB-A male-to-female connectivity for simple plug-and-play operation.

Advantages

The cable's 3 m length gives extra reach for desktop setups, workstations and home offices while maintaining a compact, flexible jacket that is easy to route and store. Standard USB-A connectors ensure wide compatibility with legacy and current devices. Passive construction preserves direct signal passthrough and requires no external power or configuration, making it a practical choice for extending existing USB-A connections quickly and reliably.

Suitable for

• Extending desktop USB ports to reach peripherals such as keyboards and mice
• Positioning printers or scanners further from a computer without relocating the host
• Connecting external hard drives or flash readers where cable length is limited
• Temporary setups and meeting rooms where devices are moved or rearranged

Key specifications

• Cable length: 3 meters
• Connector type: USB-A to USB-A (male to female)
• Color: Black
• Cable jacket: Flexible PVC for easy routing
• Function: Passive extension for data and standard USB power passthrough

How to use

Connect the male USB-A plug of the extension cable to the host or upstream USB port and insert the device's USB-A plug into the female end of the cable. Ensure connectors are fully seated to maintain reliable contact. As a passive extension, the cable mirrors the original connection and typically does not require any software or driver changes. For devices that draw higher power, connect directly to a powered port or use a powered hub if functionality is unstable.

Usage recommendations

For best results, avoid coiling the cable tightly or running it parallel to high-power electrical lines to minimise potential interference. Use the extension for typical USB peripherals and moderate data transfer tasks; for long-distance high-speed transfers or power-hungry devices consider an active extension or powered solution.
