Cable Length 5 Feet

  • Transfers large files fast with 40Gbps bandwidth
  • Charges laptops quickly using 240W Power Delivery
  • Drives one 8K display or two 4K monitors at 60Hz
  • Built-in E-Marker chip regulates power for safe charging

Professional Connectivity Solution

This USB4 Gen 3 cable delivers 40 Gbps data transfer and 240 W power delivery through a USB-C to USB-C connection. The five-foot nylon-braided design supports 8K video output and Thunderbolt 3 functionality for demanding creative and technical workflows. An integrated E-Marker chip regulates power intelligently to protect connected devices during high-wattage charging sessions.

Ideal Users and Limitations

Suits professionals who need maximum bandwidth for NVMe enclosures, eGPU docks or dual 4K monitor setups from a single port. Also fits owners of PD 3.1 laptops such as recent MacBook Pro models that accept 140 W or 240 W charging. Not for users whose devices only support USB 3.2 Gen 2 or lower, as they cannot utilise the 40 Gbps throughput or 8K video modes. Buyers requiring longer cable runs for permanent installations should look elsewhere.

What the Bundle Changes

The cable itself is the complete product; no separate adapters, docks or software utilities are included. Its E-Marker chip and PD 3.1 compliance replace the need for proprietary charging cables when powering compatible laptops, tablets or phones up to 240 W. The single cable consolidates data, video and charging roles that would otherwise require multiple specialised leads.

Questions about this item

What host-port standard is needed to reach the 40 Gbps data rate?

The cable delivers up to 40 Gbps when the host port supports USB4 or Thunderbolt 3/4.

Will the cable charge a laptop that only accepts 100 W over USB-C?

Yes, the PD 3.1 EPR chip negotiates down to 100 W, 60 W, 45 W or any lower profile the device requests.

How can I verify the link is running at 40 Gbps after plugging it in?

On Windows open Device Manager, find the USB4 controller and confirm the link speed reads Gen 3 × 2 (40 Gbps); on macOS use System Report → Thunderbolt/USB4 to see the negotiated rate.
