Cable Length 3.3 Feet

  • Charge laptops and phones at up to 240W with a compatible charger
  • Transfer large files at 40Gbps using Gen3 ports
  • Drive one 8K display at 60Hz or two 4K displays at 60Hz

Thunderbolt 4 Cable 3.3ft Braided

This SMUGDESK USB-C to USB-C cable is certified for Thunderbolt 4 and USB4 operation. It delivers up to 40 Gbps data bandwidth, supports 240 W power delivery and carries 8K video signals. The 3.3 ft braided jacket protects the conductors during daily transport and desk use.

Professionals moving large media libraries

Creative workers who need to shift 14 hours of HD video or 25,000 photos in about a minute will benefit from the 40 Gbps link. Users whose devices only offer USB 3.2 Gen 2 ports will see bandwidth limited to 20 Gbps, so they should check port specifications before expecting full throughput.

40 Gbps bandwidth with 240 W headroom

The cable comfortably handles single 8K 60 Hz or dual 4K 60 Hz streams plus simultaneous high-watt charging up to 48 V 5 A. When connected to USB 3.2 Gen 2 hosts the data path drops to 20 Gbps, and daisy-chaining more than six Thunderbolt devices exceeds the supported topology.

Questions about this item

Does the cable need a Thunderbolt 4 port on my laptop to reach its 40Gbps speed and 240W charging?

The cable works with any USB-C port, but 40Gbps data and 240W power require a host port that supports USB4 Gen3 or Thunderbolt 4; USB 3.2 Gen2 ports top out at 20Gbps and lower wattage.

If I keep my older USB 3.1 Gen2 dock, will this cable still drive a single 8K display at 60Hz through it?

No — the dock’s 10Gbps or 20Gbps link cannot carry the 40Gbps bandwidth needed for 8K@60Hz; the cable will fall back to the dock’s maximum video mode instead.

How can I verify the link is running at the full 40Gbps after I plug everything in?

On Windows open Device Manager and confirm the connection shows USB4 40Gbps; on macOS check System Report for a Thunderbolt 4 link at 40Gbps; then transfer a large file to a fast SSD and confirm throughput nears 40Gbps.
