What this cable does
The SMUGDESK USB 4 cable carries 40 Gbps data, 240 W power and 8K 60 Hz video over a single USB C to USB C link. It meets the USB 4.0 Gen 3x2 specification and works with Thunderbolt 3 and 4 hosts. Backward compatibility covers USB 3.2, 3.1 and 2.0 speeds. The 5 ft length suits desk or docking setups.
Who it suits and who it does not
Creators driving one 8K 60 Hz or dual 4K 60 Hz monitors from a Thunderbolt 4 port gain full bandwidth and charge headroom. Laptop users needing 240 W PD 3.1 fast charging benefit from the extended power range. Buyers whose devices lack DisplayPort Alt Mode cannot use the video function. Users requiring longer runs or active optical cables for signal integrity beyond copper limits should look elsewhere.
What the bundle changes
The cable itself replaces separate data, charging and video leads, reducing clutter at a workstation or docking station. Support for PD 3.1 PPS, QC 4.0 and legacy fast-charge protocols means one cable negotiates optimal voltage up to 48 V for phones, tablets, power banks or GaN chargers. No additional adapters or driver software are included or required.

Questions about this item
Does my laptop need a USB4 port to use this cable at 40Gbps?
Yes, both the host and the peripheral must support USB4 Gen 3x2 to reach 40Gbps.
Will this cable charge my older 100W USB-C laptop at full speed?
Yes, it is backwards compatible with 100W, 60W and lower power profiles.
How can I confirm the cable is delivering 240W to my device?
Check the power reading on the device or charger; it should show up to 48V at 5A when both ends support PD 3.1 EPR.
