UGREEN USB 3.0 A Male-Female Extension Cable 3M-US129

The UGREEN US129 USB 3.0 A Male to Female Extension Cable 3M provides additional reach between your computer and USB-A peripherals without requiring you to reposition your equipment.

Featuring USB-A male on one end and USB-A female on the other, it is particularly useful for desktop computers, office workstations, meeting rooms and entertainment setups where existing USB cables are too short.

USB-A Male to USB-A Female

The US129 provides a straightforward USB extension:

USB-A Male → USB-A Female

Connect the male end to your computer’s USB-A port. Then connect your existing USB device to the female end.

For example:

Computer → UGREEN US129 → USB Flash Drive

This makes difficult-to-reach USB ports much easier to access.

USB 3.0 with Up to 5Gbps

The UGREEN US129 supports the USB 3.0 standard, delivering theoretical data transfer rates of up to 5Gbps with compatible equipment. This is approximately 10 times the theoretical bandwidth of USB 2.0 at 480Mbps. Therefore, the cable is well suited to applications where faster file transfers are important.

Ideal for External HDDs and SSDs

The 5Gbps USB 3.0 interface makes the US129 suitable for connecting compatible external storage devices. It can be used with:

• External HDDs
• Portable SSDs
• USB flash drives
• Card readers
• Other USB 3.0 storage devices

Actual transfer speed depends on the computer, storage device, USB interface and files being transferred.

Extend USB Flash Drive Connections

Desktop computers often have USB ports located at the rear of the system unit. With the US129, you can extend one of these ports and position the USB-A female connector on your desk for easier access. This makes frequently connecting and removing flash drives more convenient.

Suitable for Keyboards and Mice

The cable can also extend the connection of wired USB keyboards and mice. It is useful for large desks, conference rooms, reception areas, POS installations and other environments where the computer is positioned away from the user.

Connect Webcams and Other Peripherals

The UGREEN US129 can be used with many compatible USB-A peripherals, including:

• Webcams
• Keyboards
• Mice
• Printers
• USB hubs
• USB receivers
• Bluetooth adapters
• Wi-Fi adapters
• Card readers
• Game controllers
• Flash drives
• External HDDs and SSDs

Backward Compatible

USB 3.0 maintains backward compatibility with many USB 2.0 and USB 1.1 devices. Therefore, older USB peripherals can also be connected through the extension cable. However, the connection will operate at the speed supported by the slowest device or interface.

Data and Power Transmission

The US129 carries both USB data and USB bus power. This means bus-powered peripherals can receive power through the cable, subject to the amount of power available from the original USB host port. The extension cable itself does not increase the power supplied by the computer.

Durable Construction

The UGREEN US129 is designed for regular home and professional use. Its cable construction helps protect the internal conductors, while reinforced connector areas provide improved durability during everyday plugging, unplugging and bending.

3 Metre Extended Reach

With a length of 3 metres, this US129 version provides significantly more flexibility than short USB extension cables.
