Black braided USB-C to USB-C cable 3.3ft

SMUGDESK

SMUGDESK USB4 40Gbps 240W USB C Cable 3.3ft

SKU CH-W3JT-BRT35 MPN USB4

USB4 cable delivers 40Gbps data transfer, 240W charging and 8K@60Hz video over 3.3ft length

Cable Length 3.3 Feet

Model USB4

  • Charges up to 240W with PD 3.1 EPR
  • Transfers data at 40Gbps via USB4 Gen3x2
  • Drives 8K@60Hz or dual 4K@60Hz displays
  • Built-in safety resistor limits current to 5A
  • Works with Thunderbolt 4 and Thunderbolt 3 devices

Built for 240W charging and 40Gbps data

This USB4 cable carries up to 240W of power with PD 3.1 Extended Power Range and delivers 40Gbps bi-directional bandwidth using USB4 Gen3x2. It supports single 8K at 60Hz or dual 4K at 60Hz video output over the same connection. The 3.3ft length suits desktop and portable setups alike.

Stable 5A current under continuous load

A built-in safety resistor keeps current controlled at 5A maximum, preventing disturbance during long charging sessions or large file transfers. Backwards compatibility with 180W, 140W, 100W and 60W profiles means the cable negotiates the highest safe rate automatically. Voltage tops out at 48V per the PD 3.1 specification.

Replaces lower-wattage or slower cables

If your current cable caps at 100W or 20Gbps, this one removes both bottlenecks for MacBook Pro 16-inch, high-power laptops, power tools and industrial supplies needing 240W EPR. It is not for buyers who only need 60W charging or 10Gbps data, or for devices lacking USB-C ports altogether.

Questions about this item

Will the 240W power delivery overheat the cable during all-day charging?

The cable includes a built-in safety resistor that keeps current stable at 5A, preventing current disturbance and protecting connected equipment during extended high-power use.

What charger and device are needed to reach the full 240W rating?

A USB PD 3.1 EPR charger rated at 240W and a device that supports 48V/5A extended power range are required to deliver the maximum 240W load.

Can this cable drive an 8K@60Hz monitor from a Thunderbolt 3 laptop?

Yes, it supports single 8K@60Hz or dual 4K@60Hz video output and is backward compatible with Thunderbolt 3 and Thunderbolt 4 hosts.
