SMUGDESK USB4 240W 40Gbps Cable

This USB4 Gen 3x2 Type-C cable delivers up to 40Gbps data transfer and 240W power delivery using USB PD 3.1 Extended Power Range. It supports 8K at 60Hz video output and is backwards compatible with Thunderbolt 3 and 4 devices. The 1.64ft length suits desktop connections between a host and a dock, eGPU or monitor.

Deciding specification: 240W Extended Power Range

The cable implements USB PD 3.1 EPR at 48V and 5A, enabling the full 240W rating when paired with a compatible charger and device. It also negotiates lower fixed profiles such as 180W, 140W, 100W and 60W. Without an EPR-capable source and sink the cable will fall back to standard power levels, so buyers needing 240W must verify both ends support PD 3.1 EPR.

Bundled capability impact

No additional accessories or software are included with the cable. The reversible USB-C male connectors provide plug-and-play operation for charging, data and video. The sleeved jacket adds mechanical durability for repeated insertion cycles. Users requiring dual 4K displays must purchase a second cable, as each connection carries a single video stream.

Questions about this item

What does the 40 Gbps figure mean once the cable is connected to real hardware?

The cable supports USB4 Gen 3x2 speeds up to 40 Gbps when both the host and the peripheral implement that standard. In practice, read speeds reach about 2.8 GB/s and write speeds about 2.1 GB/s, so large files move in seconds rather than minutes.

Which interface standard does the cable use and what does that cap in practice?

The cable follows the USB4 Gen 3x2 specification and is Thunderbolt 3 and 4 compatible. That limits maximum throughput to 40 Gbps and power delivery to 240 W at 48 V, while remaining backward compatible with lower USB versions.

What physical length and connector type does the cable need to fit my setup?

The cable measures 1.64 ft (0.5 m) and terminates in USB-C male plugs on both ends. The reversible, bi-directional connectors fit any USB-C port without orientation concerns.
