Product description

It’s built for high bandwidth tasks like transferring large media files and driving high‑resolution displays while delivering fast charging when your devices support USB Power Delivery.
Key features
The Silkland cable supports up to 80Gbps data transfer according to the product specs, so moving HD movies, large audio projects or multi‑gigabyte backups finishes faster. It claims throughput around 6200 MB/s and is compatible with USB4 and USB 3.2 Gen 2x2 devices, and it works plug and play with hubs, docks and SSDs.

Why it’s worth it
If you regularly move large files or use an external SSD, this cable reduces wait times and removes the need to swap plugs constantly. It also supports high refresh and high resolution video, including single 4K at 540Hz and multi‑display outputs up to dual 8K/6K at 60Hz or triple 4K at 144Hz when full chains support those modes. Note that both source and display hardware and any intermediary hub must support the chosen resolution and refresh rate.
Usage tips
You’ll appreciate it if you need extra reach without losing performance for docking stations or Thunderbolt hubs. Use the included cable tie to keep things tidy and avoid tight bends near the connectors. For fastest charging and top data speeds, pair it with chargers and devices that explicitly support USB‑PD and USB4 or Thunderbolt specifications.
The cable’s aluminum shell and tinned copper conductors aim to keep connections stable and protected during daily use, making it a practical extender for laptops, tablets and compatible mobile devices.
