Silkland USB4 for Thunderbolt 4 Cable 1.5M 40Gbps

Silkland USB4 for Thunderbolt 4 Cable packs high transfer speeds and robust charging into a compact 1.5 metre USB‑C lead, ideal for laptops, tablets and docks. It blends fast data movement with display and power capabilities, so you can move large files, power a machine and drive an external screen without swapping cables.

Key points

This USB4 cable delivers up to 40Gbps data transfer and supports PD3.1 charging up to 240W according to the manufacturer, with an E‑Marker chip for stable voltage and thermal protection. It handles single 8K@60Hz or dual 4K@60Hz outputs, so it suits presentations, video editing and high resolution playback. The construction uses aluminium connectors, a nylon jacket and gold plated contacts for everyday durability. Keep in mind that the 240W figure requires compatible hosts and chargers, and your device must also support the relevant PD profile.

Benefits

You get a single cable that reduces clutter, charging and moving data at higher rates than older USB standards. The E‑Marker support helps protect both host and device from unstable power delivery. The rugged build makes it practical for daily carry and frequent connect cycles.

How to use it

Plug the cable between a USB‑C port on your laptop or dock and a compatible monitor, SSD or charger for instant use, no drivers required. If you prioritise maximum charging speed use a PD3.1 rated charger and check that your laptop accepts 48V input, if not the cable will simply negotiate a lower safe power level. You’ll like it if you want fewer cables, reliable high speed transfers and crisp external display output for work or media.

Care & maintenance

Avoid sharp bends and keep the connectors free of dust to maintain performance and contact quality. Wipe the nylon jacket with a damp cloth if needed and store the cable coiled loosely rather than tightly wrapped.
