What this cable does

The SMUGDESK USB4 cable is a Thunderbolt 4 certified USB-C to USB-C link rated for 40Gbps data, 8K video at 60Hz and up to 240W power delivery. It suits professionals moving large media libraries, creators driving high-resolution displays and anyone charging laptops or peripherals through a single cable.

Replaces slower USB-C leads

It upgrades from cables limited to 20Gbps Gen2 bandwidth or lower power profiles, letting you reach full Gen3 40Gbps throughput and 48V 5A charging when both host and device support it. The jump matters when you need dual 4K@60Hz output, eGPU bandwidth or the fastest possible charge for power-hungry laptops.

Build fit: one cable for dock, display and power

Plug it into a Thunderbolt 4, Thunderbolt 3, USB4 or USB-C port to carry data, video and up to 240W charging simultaneously. It frees you from carrying separate display and power cables, though actual speeds and wattage still depend on the capabilities of the connected ports and charger.

Questions about this item

Does the 5 ft cable reach a monitor on a standard desk without strain?

The 5 ft length spans a typical desk-to-monitor distance so the USB-C connectors sit flat without pulling on the ports.

Which way round do the USB-C plugs go for 240W charging?

Either end works — both connectors are identical USB-C, so insert either side into the charger and the other into the laptop.

When should I replace the cable if the 40Gbps speed drops?

If large transfers fall to 20Gbps or video drops from 8K@60Hz to 4K, the internal wiring has likely degraded and the cable should be swapped.
