What this cable does and who needs it

This USB4 cable carries data at up to 40 Gbps, delivers up to 240 W of power and drives an 8K display over a single 1.5 ft USB-C to USB-C link. It suits anyone connecting a modern laptop, phone, hub or dock that supports the USB4 Gen 3x2 standard.

How the supported power profiles change charging

The cable implements PD 3.1 extended power range plus PD 3.0 PPS, PD 2.0, QC 4.0, QC 3.0, AFC, SCP and FCP, so it negotiates the highest voltage the charger and device both accept. Backward compatibility covers 180 W, 140 W, 100 W, 60 W and lower levels without extra cables.

Limits of the USB4 Gen 3x2 interface

Full 40 Gbps throughput and 240 W delivery require a host, charger and peripheral that all implement USB4 Gen 3x2 and PD 3.1 EPR; older ports fall back to their own maximum speeds and power. The 1.5 ft length keeps signal loss low but restricts placement to very close devices.

Questions about this item

How often will the USB-C connectors on this 1.5 ft cable need replacement under normal use?

The USB-C male connectors are rated for thousands of insertion cycles; with typical daily plugging they should last years before any wear appears.

What is the first limit reached when this cable runs at 40 Gbps continuously?

Sustained 40 Gbps throughput is limited by the connected devices' controllers and thermal throttling, not by the cable's USB4 Gen 3x2 specification.

How much heat does the cable generate when delivering 240 W all day?

At 240 W the cable stays cool to the touch because its conductors are sized for the full 48 V / 5 A Extended Power Range without measurable temperature rise.
