Product Features
Technical Overview
This USB4 cable meets the full USB4 specification, providing a 40 Gbps bi-directional data throughput that is perfectly suited for high-bandwidth applications such as external NVMe SSDs, video production workflows, and multi-display setups. The integrated E-marker chip communicates the cable's capabilities to the host device, ensuring safe and optimized power delivery up to 240W (48V/5A) with USB PD 3.1, enabling rapid charging of even the most power-hungry laptops.
Video performance reaches up to 8K 60Hz (7680 x 4320) or dual 4K 120Hz over a single cable, leveraging DP2.1 (UHBR10) and DSC for high-efficiency compression. This makes the cable an excellent choice for driving high-resolution displays from a docking station or direct USB-C connection. The 30/32 AWG gauge wire, combined with braided copper and foil shielding, minimizes signal loss and EMI interference, maintaining signal integrity over the cable length.
Key Product Advantages
The StarTech.com USB4 Cable combines high-speed data, video, and power delivery in a single, convenient cable, reducing desktop clutter and simplifying connectivity. Its certification and built-in E-marker provide peace of mind for critical workflows, ensuring consistent performance and safe charging.
Versatile Connectivity
Works seamlessly with USB4, Thunderbolt 4, and USB-C devices, including docking stations, external GPUs, monitors, and laptops. Backward compatible with earlier USB standards.
Durable Build
The braided TPE jacket resists tangling and everyday wear, while the shielded construction protects against EMI in electrically noisy environments.
Easy Identification
Quick ID connector markings allow instant identification of cable specifications, saving time during setup and troubleshooting.
Deployment / Use Cases
This 1.5-foot USB4 cable is purpose-built for close-proximity connections between laptops and docking stations, portable monitors, or USB-C hubs. Its short length minimizes cable clutter on desks or in mobile workstation bags, while maintaining full high-speed performance.
