USB hub c-tech UHB-U3-AL — 4x USB 3.2 Gen 1 ports, aluminum body

The USB hub c-tech UHB-U3-AL offers four USB 3.2 Gen 1 ports in a compact aluminum housing, enabling high-speed data transfer up to 5 Gbps. Designed to expand the number of available USB ports on laptops and desktops, this hub uses an integrated USB cable for a simple plug-and-play connection. The aluminum body provides improved durability and passive heat dissipation, making it suitable for connecting external drives, flash drives, keyboards, mice and other USB peripherals.

Advantages

The hub supports USB 3.2 Gen 1 performance for fast file transfers and responsive peripheral connections while remaining backward compatible with USB 2.0 and USB 1.1 devices. Its aluminum construction increases mechanical robustness and helps dissipate heat during continuous use. The compact design and integrated cable reduce desktop clutter and make the hub easy to carry with a laptop. No additional drivers are required for most modern operating systems, enabling quick setup.

Suitable for

• Expanding USB connectivity on laptops and ultrabooks with limited ports
• Connecting external hard drives and SSDs for file transfer and backups
• Attaching keyboards, mice and other input devices for desktop or mobile use
• Using flash drives and card readers that rely on standard USB-A connections

When it may not be suitable

This hub provides four standard USB-A ports and is intended for data transfer and peripheral connectivity rather than for delivering high power to multiple demanding devices simultaneously. It does not include a separate power adapter; therefore, powering several high-draw devices at once (for example, multiple bus-powered hard drives) may exceed the host port’s available current. The integrated cable length is fixed, which may limit placement flexibility in some setups.

Key specifications

• Interface: USB 3.2 Gen 1 (backward compatible with USB 2.0 / USB 1.1)
• Number of ports: 4 x USB-A
• Maximum data transfer rate: up to 5 Gbps
• Housing material: aluminum
• Connectivity: integrated USB cable (host connection)
• Power: bus-powered from host USB port (no external power supply included)
• Compatibility: Windows, macOS, Linux and other systems with standard USB support

How to use

Connect the integrated cable to an available USB port on your computer or compatible host device. Once connected, the hub is typically recognized automatically and the four USB-A ports become available for use. Attach peripherals such as external drives, flash drives, keyboards or mice to the hub’s ports. For optimal performance with high-speed storage devices, connect to a USB 3.0/3.2 host port. Avoid connecting multiple high-current devices simultaneously if the host cannot supply sufficient power.

What to consider before purchase

• Check that your host device has a USB 3.0/3.2 port to take full advantage of 5 Gbps speeds
• Consider whether you require an externally powered hub for multiple power-hungry devices
• Verify the integrated cable length and whether its placement suits your workspace
• Confirm compatibility with your operating system if using older or specialized platforms

Usage recommendations

For reliable high-speed transfers, connect the hub to a USB 3.x host port and use high-quality USB 3.0/3.2 cables and storage devices. To prevent power-related issues, attach externally powered drives to their own adapter or use a powered hub when connecting several bus-powered devices. Keep the aluminum housing free of heavy dust buildup to maintain passive cooling efficiency.
