Cable Length 3.3 Feet

  • Transfer files at 40Gbps for SSD and eGPU workflows
  • Charge a MacBook Pro 16 to 60% in 30 minutes with 240W PD 3.1
  • Drive one 8K display or two 4K monitors at 60Hz
  • Single cable handles data, video and power up to 240W
  • Built to USB 4.0 spec for broad device compatibility

Thunderbolt 4 cable for high-speed workflows

This Thunderbolt 4 cable targets creators and professionals who move large project files between external SSDs, eGPU enclosures and docking stations. The 3.3 ft length suits desktop setups where the host and peripheral sit side by side on the same surface. It replaces multiple legacy cables by handling data, video and power in a single run.

Sustained 40 Gbps throughput

Rated at 40 Gbps, the link maintains full bandwidth during extended transfers to NVMe storage or while driving an 8K 60 Hz display or dual 4K 60 Hz monitors. The USB Power Delivery 3.1 Extended Power Range profile negotiates 48 V at 240 W, 36 V at 180 W and 28 V at 140 W, so a 16 inch MacBook Pro can reach 60 % charge in 30 minutes without throttling the data path.

Plug-and-play USB-C to USB-C

Both ends use standard USB-C connectors, so the cable inserts either way up and works with any Thunderbolt 4, USB4 or USB 3.x port. The supplier notes a soft, pliable jacket that resists kinking better than stiffer 100 W or 240 W alternatives, reducing strain on ports during frequent connect and disconnect cycles. Not suited for buyers who need longer runs beyond 3.3 ft or angled connectors for tight chassis clearance.

Questions about this item

Does the 240W PD 3.1 charging generate noticeable heat during long sessions?

The cable carries up to 48V at 240W through PD 3.1 EPR; it is built with durable, flexible materials to handle sustained high-power delivery without excessive heat buildup.

Must my laptop and monitor both support Thunderbolt 4 or USB4 to use the 40Gbps data and 8K video?

Yes, the 40Gbps transfer rate and 8K@60Hz or dual 4K@60Hz video output require host and display devices that implement Thunderbolt 4 or USB4 with Alt Mode.

Will this cable work at full speed with my older USB 3.2 Gen 2×2 SSD enclosure?

The cable is backward compatible with USB 3.2, 3.1, 3.0 and 2.0, but the enclosure will operate at its own maximum speed, not the cable's 40Gbps ceiling.
