SMUGDESK USB 4 Thunderbolt 4 Cable 1.5FT 40Gbps 240W

SKU CH-RSNW-WN2D4

A 1.5FT USB-C cable delivering 40Gbps data, 240W charging and 8K@60Hz video for Thunderbolt 4 and USB4 devices

Cable Length 1.6 Feet

  • 240W power delivery charges high-draw laptops at full speed
  • 40Gbps bi-directional bandwidth moves large files in seconds
  • 4K at 144Hz or 8K at 60Hz drives pro displays without compression
  • Thunderbolt 4 and USB4 Gen 3x2 compatibility works with current docks and monitors
  • 5ft length keeps desktop setups tidy and signal integrity high

Purpose & Audience

This USB 4 cable connects laptops, docks and monitors that accept USB C. It suits users who need 40 Gbps data transfer and up to 240 W power delivery in a 1.5 FT length. It is not for buyers who require longer reach or legacy USB A connectors.

Thermals, Noise & Power

The cable handles up to 48 V and 240 W through PD 3.1 Extended Power Range, with backward compatibility down to 60 W. Passive construction means no fan noise or active cooling is involved.

Sustained Load Behaviour

Under continuous 240 W charging or 40 Gbps throughput the cable maintains rated voltage and speed without throttling. It supports 4K at 144 Hz, 5K at 60 Hz and 8K at 60 Hz video signals during extended sessions.

Questions about this item

How do I connect the 1.5FT USB C Male to USB C Male cable so the bi-directional 40Gbps link works?

Plug either end into the host and the other into the device; the reversible USB C connectors prevent upside-down insertion, which is the step users most often fumble.

Will the 240W Extended Power Range capability degrade and require cable replacement over time?

The cable itself has no wear-out components; only the connectors can loosen after thousands of cycles, so replace it if the plug feels loose or charging drops below the negotiated wattage.

At what point does the 40Gbps data rate throttle during a sustained large-file transfer?

The 40Gbps ceiling is set by the USB4 Gen 3x2 signalling; thermal limits in the host or device controller typically throttle first, not the cable.
