StarTech.com USB4 Cable 1m, 40 Gbps, 100W

This USB4 cable of 1m supports up to 40 Gbps data transfer and can carry 100 W Power Delivery, making it practical for fast syncing, high-resolution video and charging a laptop from a single connection. It suits users who need a compact cord for connecting Thunderbolt 4/3 laptops, docking stations or UHD monitors while keeping cable clutter to a minimum.

Key Points

The cable handles high-bandwidth tasks such as transferring large files or driving an external display at up to 8K 60Hz. For video it supports DisplayPort 1.4 with DSC which also allows 4K at 120Hz when the host and display support it. It is USB-IF certified and includes an E-Marker chip to negotiate Power Delivery reliably, which helps maintain consistent charging up to 100 W with compatible hosts and devices. The connectors are nickel-plated and the cable uses a coaxial core with Mylar shielding to reduce electromagnetic interference, improving signal integrity in busy workspaces. Note that peak display modes depend on the capabilities of the computer and monitor, according to the manufacturer.

Usage Recommendations

Use this cable for connecting modern USB-C laptops and Thunderbolt systems to docking stations and UHD monitors, especially when a single-cable solution for power, video and data is desired. It is compact enough for travel yet robust for daily desk use, thanks to its strain reliefs and environmental TPE jacket which is halogen-free and RoHS compliant. For the best performance, pair with devices that explicitly support USB4 or Thunderbolt 4/3 and ensure that both ends of the chain meet the bandwidth and PD requirements. Consider that very long runs may reduce achievable throughput and that legacy devices will operate at their native lower speeds.
