USB4 cable with 40 Gbps bandwidth

This USB4 Gen 3x2 cable carries up to 40 Gbps of bi-directional data between compatible hosts and peripherals. It supports 8K video output and works with Thunderbolt 3 and 4 devices. The 1.5 ft length keeps signal paths short for reliable high-speed transfers. An integrated E-Marker chip ensures correct power and data negotiation.

Sustained 240 W power delivery

The cable handles Extended Power Range up to 240 W at 48 V under the PD 3.1 specification. It remains backward compatible with 180 W, 140 W, 100 W and 60 W profiles, so a single cable can charge laptops, phones and hubs at their maximum supported rates. PD 3.0 PPS, QC 4.0 and other fast-charge protocols are also supported for broad device coverage.

Simple plug-and-play installation

Reversible USB-C connectors remove orientation guesswork, and the braided jacket resists tangling during frequent connects. No drivers or firmware updates are required; the E-Marker communicates capabilities automatically. The short 1.5 ft reach suits desktop docks and portable SSDs but will not span longer distances between desk and display.
