Nylon braided USB-C to USB-C cable 1.5FT

SMUGDESK

SMUGDESK USB4 Gen 3 Cable 1.5FT 40Gbps 240W 8K

SKU CH-GT0G-B49CW

A 1.5 ft USB cable delivers 40 Gbps data transfer, 240 W charging and 8K video output

Cable Length 1.5 Feet

  • Transfers 2.5 GB files in one second at 40 Gbps
  • Charges MacBook Pro 16 to 60 % in 30 minutes with 240 W PD 3.1
  • Drives one 8K display at 60 Hz or dual 4K at 60 Hz
  • E-Marker chip regulates power and protects battery during charging
  • Nylon-braided 1.5 ft cable works with Thunderbolt 4/3 and USB4

Efficient 40Gbps Transfer Cable

This USB4 Gen 3 cable reaches a 40Gbps maximum data rate, moving 2.5G files in one second. It suits users who connect NVMe enclosures, eGPU docks or high-speed SSD drives and need the full bandwidth those devices can use. The 1.5FT length keeps the signal path short for reliable throughput.

Replaces Slower USB and TB2 Links

It doubles the ceiling of USB 3.2 Gen2X2 and Thunderbolt 2 cables, so the jump is worth it when your workflow saturates a 20Gbps link. Backward compatibility with Thunderbolt 4, Thunderbolt 3 and USB4 means existing ports work, but only hosts that negotiate the higher rate will see the gain.

Practical Limits of USB4 Gen 3

Video output requires the host port to support DisplayPort Alt Mode; without it the cable carries only data and power. Dual 4K@60Hz or a single 8K@60Hz stream is the ceiling, and 4K@144Hz is possible on one display. The E-Marker chip negotiates PD 3.1 up to 240W, yet actual wattage depends on the charger and device capabilities.

Questions about this item

What USB-C port capability is required on my laptop for the cable to drive an 8K display at 60 Hz?

The host USB-C port must support DisplayPort Alt Mode; without it the cable cannot output video regardless of its 40 Gbps rating.

Which orientation of the USB-C plugs ensures the E-Marker chip negotiates 240 W charging correctly?

Either orientation works — the reversible USB-C connectors and built-in E-Marker handle power negotiation automatically once both ends are fully seated.

How often should I inspect the nylon-braided jacket and connectors for wear that could affect 40 Gbps signal integrity?

Check the braid and metal shells every few months; frayed fibres or bent pins can degrade the 40 Gbps link and 240 W power delivery.
