USB-A extension cable Unitek Y-C1479BBK03 — male to female, 3.0, 3 m

The Unitek USB-A extension cable Y-C1479BBK03 is a 3.0 USB-A male-to-female extension designed to extend the reach of existing USB-A ports by 3 metres. It supports USB 3.0 data transfer rates for compatible devices while remaining backwards compatible with USB 2.0 and USB 1.1 peripherals. The cable lets you position external drives, input devices or charging accessories at a more convenient distance from the host computer without moving the host itself.

Advantages

This USB-A extension cable provides a full 3-metre extension with a durable moulded connector design and shielding to maintain signal integrity at USB 3.0 speeds. The male-to-female configuration preserves plug compatibility and allows easy connection of standard USB-A plugs. The cable construction is aimed at stable data transfer and reliable power delivery for most USB peripherals.

Suitable for

• Extending connection for external hard drives and USB flash drives
• Providing easier access to USB ports for keyboards, mice and other peripherals
• Temporary or semi-permanent extension for charging mobile devices from a distant port
• Desk setups where the host computer is hard to reach or positioned under furniture

When it may not be suitable

This extension cable is suitable for general-purpose USB-A devices but may not meet the requirements of applications that demand guaranteed maximum throughput for very long cascaded chains of connectors or the absolute lowest latency. For devices that require USB-C features such as alternate modes, power delivery at high wattages, or Thunderbolt compatibility, this USB-A extension is not appropriate.

Key specifications

• Connector type: USB-A male to USB-A female
• USB standard: USB 3.0 (backwards compatible with USB 2.0 and USB 1.1)
• Cable length: 3 m
• Compatible functions: data transfer and standard USB charging
• Construction: shielded cable with moulded connectors for strain relief

How to use

Plug the USB-A male end of the extension into an available USB-A port on your computer or power adapter. Connect your USB-A peripheral to the female socket of the extension. The operating system should detect connected storage or input devices automatically; ensure device drivers are installed when required. Avoid sharp bends and excessive tension on the cable to preserve performance and longevity.

What to consider before purchase

• Confirm your device uses a standard USB-A connection and does not require USB-C specific features.
• Check whether USB 3.0 bandwidth is required for your peripheral; for low-speed devices USB 2.0 compatibility may be sufficient.
• Consider cable routing and physical length—3 m adds convenience but may introduce clutter if not managed.

Usage recommendations

For best results, connect directly to a USB 3.0 port on the host rather than through multiple adapters. Keep the cable free of tight coils and away from sources of strong electromagnetic interference to maintain stable transfer rates and charging performance.
