UGREEN USB 3.0 Extension Male Cable 1.5m US129

The UGREEN US129 USB 3.0 A Male to Female Extension Cable 1.5M provides a convenient way to extend an existing USB-A port. It is particularly useful when USB ports are difficult to reach or when the connected peripheral has a short cable. With USB 3.0 connectivity, the cable combines additional reach with high-speed data transmission for modern USB peripherals.

USB-A Male to USB-A Female

The US129 features: USB-A Male → USB-A Female

Connect the USB-A male end to a laptop, desktop computer or compatible USB host. The USB-A female end then accepts your USB peripheral.

For example:

Computer → UGREEN US129 → USB Flash Drive

This effectively moves the computer’s USB port to a more convenient location.

Up to 5Gbps USB 3.0 Data Transfer

The UGREEN US129 supports USB 3.0 data transmission up to 5Gbps when used with compatible USB 3.0 equipment. This provides substantially more bandwidth than USB 2.0, which has a theoretical maximum of 480Mbps. Therefore, the US129 is suitable for transferring large files using compatible storage devices.

Suitable for External HDDs and SSDs

The high speed USB interface makes the US129 useful with compatible:

• External hard drives
• Portable SSDs
• USB flash drives
• Memory card readers
• Other USB storage devices

Actual transfer speeds depend on the computer, USB controller, connected device and storage performance.

Extend Hard to Reach USB Ports

Desktop computers often have USB ports at the back of the system unit. These can be inconvenient when frequently connecting flash drives, card readers or other accessories. The US129 allows you to extend the port onto your desk for easier access.

Suitable for Keyboards and Mice

The cable can extend the connection of compatible wired USB keyboards and mice. It can also be useful when connecting USB wireless receivers where positioning the receiver closer to the keyboard or mouse may be desirable.

Webcam Extension

The US129 can provide additional cable length for compatible USB webcams. This can be helpful when the webcam needs to be mounted on a monitor, TV, conference-room display or another location farther from the computer.

Wide USB Peripheral Compatibility

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

• USB flash drives
• External HDDs
• Portable SSDs
• Keyboards
• Mice
• Webcams
• Printers
• Card readers
• Game controllers
• USB receivers
• Bluetooth adapters
• Wi-Fi adapters
• USB hubs
• Other compatible USB-A peripherals

Backward Compatibility

The USB 3.0 interface is backward compatible with many USB 2.0 and USB 1.1 peripherals. However, when an older USB device is connected, the connection operates at the lower speed supported by that device.

Data and Power Transmission

The US129 carries both USB data and bus power from the host USB port. Therefore, many low-power USB peripherals can operate normally through the extension cable without requiring a separate power adapter. However, the cable does not increase the amount of power available from the computer.

Convenient 1.5-Metre Length

The 1.5-metre length provides useful additional reach without introducing excessive cable clutter.

It is suitable for:

• Desktop computers
• Office workstations
• Home offices
• Meeting rooms
• Computer labs
• POS installations
• Entertainment systems

Durable Construction

The UGREEN US129 is designed for regular use. Its protective outer jacket helps safeguard the internal conductors, while reinforced connector areas improve durability during everyday cable handling.

Plug and Play Operation

No software or drivers are required for the cable itself. Simply connect: USB Host → US129 → USB Peripheral

The operating system will then detect the connected USB device according to its normal compatibility requirements.
