USB 4 Cable 3.3FT 40Gbps 240W

This USB 4 cable connects USB-C devices for charging, data and video. It serves laptop owners, desktop users and anyone linking a monitor, dock or external SSD with a single cable.

Practical limits of USB 4 and Thunderbolt

The cable delivers up to 40Gbps with USB 4 Gen3 or Thunderbolt ports, but drops to 20Gbps on Gen2 ports. Video output reaches 8K at 60Hz or dual 4K at 60Hz when the host and display support those modes. Power delivery tops out at 240W (48V/5A) only when both the charger and the device negotiate that level.

40Gbps bandwidth decides fit

If the connected port is limited to 20Gbps, the cable cannot exceed that speed. Buyers who need guaranteed 40Gbps throughput must confirm their host, dock and peripheral all operate at USB 4 Gen3 or Thunderbolt 3/4.

Questions about this item

Should I choose the 3.3FT or 1.6FT length for my setup?

The 3.3FT cable offers more reach for desktop docking stations or monitors, while the 1.6FT version reduces clutter for portable SSD or phone charging. Both support the same 40Gbps data and 240W charging limits.

What does the 40Gbps rating mean when I copy files to an external SSD?

You can transfer up to 25000 photos or 14 hours of HD video in about one minute, provided the host port and drive both run at USB4 Gen3 40Gbps; a Gen2 port caps the link at 20Gbps.

Will this cable deliver 240W through any USB-C port?

It carries up to 48V at 5A, but the actual power is negotiated between the charger and the device; both ends must support USB Power Delivery 3.1 for the full 240W.
