Silkland USB4 Cable 5m 20Gbps for Thunderbolt
Product description
This USB4 cable for Thunderbolt 4 at 5 m and 20 Gbps lets you connect a laptop, dock or compatible smartphone to high-resolution monitors for extended desktop, presentations and gaming. It combines long reach with fast data transfer and high-power delivery, making it useful when a single cable connection is preferred for video, data and charging.
Key Points
The cable supports single 8K at 60 Hz or dual 4K at 60 Hz and can also handle 4K at 144 Hz for gaming monitors, so you can upscale visual workflows or run multiple displays from one port. 🌟 The braided nylon sheath and multiple shielding layers aim to reduce interference and improve durability over repeated use.
Compatibility covers USB4 and USB Type-C devices and is backward compatible with Thunderbolt 3, USB 3.2 Gen 2 and earlier standards, allowing connection to monitors, laptops, docking stations and external SSDs. The integrated E-Marker chip negotiates power and data profiles to maintain a stable connection and protect connected equipment.
The cable is plug-and-play, requiring no additional drivers. Consider that very old USB-C ports may not expose every feature, and the highest video or charging rates depend on the connected host and display capabilities.

Usage Recommendations
Use this cable to replace multiple connections when you need video, fast file transfers and high-wattage charging through one port. It is convenient for MacBook Pro setups, Windows laptops with USB-C alt mode, docking stations and high-resolution displays where cable length matters. ⚡ For external SSDs and heavy data tasks, the 20 Gbps bandwidth shortens backup and transfer times compared with older USB standards.
When relying on the full 240W charging capability, ensure both the charger and host device support PD3.1 48V profiles, as practical charging speed will vary with the power source and the device’s power management. For long runs and monitor setups, keep moderate cable routing to avoid sharp bends that could stress the connector or braid.
