Silkland S3401 USB4 Cable, 1 ft, 80Gbps Data, 240W Charging

The 1-foot length keeps a nearby connection between a laptop, dock, or SSD compact and easy to manage. It suits a desktop setup where devices sit close together and extra cable slack gets in the way.

With USB4 data transfer up to 80Gbps and display bandwidth up to 120Gbps, the cable is built for fast transfers and demanding monitor setups. Actual data speed depends on the connected devices.

It also supports up to 240W charging with USB Power Delivery 3.1. A braided nylon exterior, aluminum housing, and E-Marker chip round out a cable designed for daily data, display, and power connections.

Everyday compatibility

Use the Silkland S3401 to connect compatible USB-C laptops, phones, tablets, SSDs, docking stations, and monitors. Its backward compatibility with Thunderbolt 4 and 3, USB4, and USB 3.2 helps it fit into setups that combine newer and earlier devices. The short cable is especially practical when a laptop is beside a dock or an external drive, keeping the connection contained rather than routing a longer cable across the desk.

For display work, the listed bandwidth supports configurations including dual 8K or 6K displays, triple 4K at 144Hz, and 4K at 540Hz, depending on the connected equipment. For charging, 240W maximum power and PD 3.1 support make it suitable for compatible power-hungry devices. The E-Marker chip is designed to support safe, stable power delivery.

Best use cases

Connect a nearby laptop to a dock, attach an external SSD for file transfers, or link a compatible USB-C device to a monitor. The cable’s bidirectional 80Gbps data transfer is useful when moving files between compatible devices, while its higher display bandwidth is intended for high-resolution or high-refresh-rate monitor setups. Its compact length works well for close desktop connections, a longer cable is a more practical choice when devices need to sit farther apart.

The braided nylon design helps resist tangling, and the aluminum housing adds a durable finish to a cable that may be connected and disconnected as a desk setup changes. Buyers often highlight its build and data-transfer performance. Feedback on connectivity is mixed, with some reporting secure connections and others describing loose connections or issues with 6K monitors, so the connected devices and setup matter.
