3.3 ft Thunderbolt 4 cable

This 3.3 ft cable carries USB4 and Thunderbolt 4 signals with full backward compatibility to earlier USB and Thunderbolt 3 standards. It suits users connecting external SSDs, docks or eGPU enclosures to laptops and desktops that have USB-C ports supporting the 40Gbps tier. Copper conductors and shielding protect signal integrity over the one-metre length.

Sustained 40Gbps throughput

The cable is certified for 40Gbps operation, so long file transfers and continuous video streams maintain rated speed without throttling. An integrated PD Emarker enables 100W power delivery at 20V and 5A, allowing the same cable to charge a host while driving data and display traffic simultaneously. Daisy-chaining up to six devices is supported without signal degradation.

Replaces slower USB-C cables

Builders using generic USB-C cables limited to 10Gbps or 20Gbps gain the full 40Gbps bandwidth plus 8K at 60Hz or dual 4K at 60Hz video capability. The upgrade is worth it when a single-cable dock, high-speed RAID or eGPU demands the certified throughput and 100W charging headroom. Buyers who need longer runs or optical isolation for electrically noisy environments cannot meet that need with this copper cable.

Questions about this item

Does the 40Gbps Thunderbolt 4 cable generate noticeable heat when used continuously for all-day data transfers?

The cable uses copper conductors with shielding and carries up to 100W at 20V/5A; it is rated for 40Gbps operation and normal warmth is expected under sustained full-load use.

What port type must my laptop or dock already have for this male-to-male USB-C cable to work?

Your device needs a USB-C port that supports Thunderbolt 4, Thunderbolt 3 or USB4; the cable is backward compatible with USB 3.2, 3.1, 3.0 and 2.0 speeds.

Will this 3.3 ft cable drive an older 4K 60Hz monitor when daisy-chained from a Thunderbolt 3 dock?

Yes, it supports dual 4K at 60Hz and is backward compatible with Thunderbolt 3, so a legacy 4K 60Hz display will work in a six-device daisy chain.
