What this cable does
The SMUGDESK USB4 cable connects USB-C devices, docks and eGPU enclosures with a single 1.5 ft lead. It handles 40 Gbps bi-directional data and 240 W power delivery so one cable can drive high-resolution displays and charge a laptop at the same time.
Where the standard stops
USB4 Gen 3x2 tops out at 40 Gbps and 240 W, so longer runs or higher bandwidth needs would exceed the specification. The 1.5 ft length keeps signal integrity within the standard but offers no slack for distant peripherals.
The spec that decides fit
If your charger, dock or laptop requires 240 W at 48 V over USB PD 3.1 this cable meets the requirement; devices limited to lower power profiles will still work but cannot draw the full 240 W.

Questions about this item
Should I choose the 1.5FT length or a longer cable for my desk setup?
The 1.5FT cable suits tight spaces like docking a laptop beside a monitor; pick a longer version only if devices sit further apart.
Will the 40Gbps rating deliver that speed between my laptop and an eGPU enclosure?
You will see up to 40Gbps when both host and eGPU support USB4 Gen 3x2; otherwise the link falls back to the highest shared rate.
Does the USB4 Gen 3x2 interface cap charging at 100W like older cables?
No — this cable carries the Extended Power Range up to 240W at 48V, so it supports 140W and 240W PD 3.1 chargers without bottleneck.
