What this cable is and who needs it
This USB4 cable carries 40 Gbps data and up to 240 W power through a 3.3 ft USB-C to USB-C link. It suits professionals moving large media files between laptops, SSD enclosures and monitors, and users charging high-wattage notebooks from a single cable. Buyers who need longer reach or optical isolation should look elsewhere.
Build quality and daily connector experience
The reversible USB-C plugs insert either way and lock firmly into Thunderbolt 3 and USB4 ports. Extended Power Range support means the same cable negotiates 48 V at 5 A for 240 W, then drops cleanly to 180 W, 140 W, 100 W or lower profiles without re-plugging. No active electronics are exposed, so the assembly stays thin and flexible for desk routing.
Practical limits of the USB4 Gen 3x2 interface
40 Gbps throughput only appears when both host and device implement USB4 Gen 3x2; older USB 3.2 or Thunderbolt 3 links fall back to their native ceilings. Full 240 W delivery requires a PD 3.1 EPR charger and a device that accepts 48 V — standard 100 W adapters will cap the cable at their rated output. Video at 8K 60 Hz demands DisplayPort Alt Mode support on both ends.

Questions about this item
Does the USB4 Gen 3x2 interface really deliver 40 Gbps in everyday use?
The cable is rated for up to 40 Gbps with USB4 Gen 3x2 devices; actual throughput depends on the host, peripheral and any hub in the chain.
What physical clearance does the USB-C male-to-male connector need?
The reversible USB-C plugs fit any standard USB-C port; allow enough cable radius behind the device for the 3.3 ft length.
How do I get 240 W charging instead of a lower rate?
Use a PD 3.1 EPR charger rated for 240 W (48 V / 5 A) and a device that negotiates Extended Power Range; otherwise the cable falls back to 180 W, 140 W, 100 W or lower.
