USB4 cable with 40 Gbps and 240 W

This USB C to USB C cable carries the latest USB4 Gen 3x2 standard and reaches 40 Gbps data transfer with compatible devices. It delivers up to 240 W at 48 V using PD 3.1 Extended Power Range and is backwards compatible with Thunderbolt 3 and earlier USB versions. The 3 ft grey cable suits laptops, docks and monitors that need maximum bandwidth and charging in one lead.

Users needing 8K 60 Hz or 140 W laptop charging

Creative professionals driving an 8K display at 60 Hz or dual 4K monitors will get the required throughput, while MacBook Pro 16 inch owners can charge at the full 140 W supported by Apple's EPR charger. Buyers whose devices only support lower USB or Thunderbolt speeds, or who need longer cable runs for permanent installs, should look at something else.

40 Gbps bi-directional data rate

The single specification that decides fit is the 40 Gbps bi-directional data rate paired with 240 W PD 3.1 power delivery; if the host and peripheral both support USB4 Gen 3x2 and EPR, this cable will saturate the link, otherwise a lower-spec cable will suffice.

Questions about this item

Does the 240 W power delivery generate noticeable heat during long charging sessions?

The cable supports up to 240 W at 48 V and 5 A, so extended high-load charging will produce some warmth, which is normal for any cable handling that power level.

What charger and device must I already own to reach the 240 W rating?

You need a PD 3.1 EPR charger rated for 240 W and a device that accepts 240 W input; the cable is backward compatible with 180 W, 140 W, 100 W and lower profiles.

Will the 40 Gbps data rate work with my Thunderbolt 3 dock and older USB 3.2 peripherals?

Yes, the cable is backward compatible with Thunderbolt 3, USB 3.2, USB 3.1 and USB 3.0, though speeds will fall back to the highest standard both ends support.
