SMUGDESK USB4 cable 240W 40Gbps 1.5 ft

What the cable is and who it is for

This USB4 cable delivers up to 40 Gbps data transfer and 240 W power delivery in a 1.5 ft male-to-male format. It suits users who need maximum bandwidth and charging speed between compatible laptops, docks or storage devices.

Build quality and daily connector implications

The cable carries an E-Mark chip enabling the 240 W (48 V/5 A) rating and supports Thunderbolt 3 and 4 hosts as well as USB 3.2, 3.1 and 2.0 devices. Its short length keeps desk routing tidy while the reinforced ends resist repeated plug cycles.

Practical limits of the USB4 interface

Video output requires the host port to support DisplayPort Alt Mode; without it the cable carries only data and power. Dual 4K@60 Hz operation needs two separate cables, and real-world throughput tops out near 2.8 GB/s read and 2.1 GB/s write depending on the connected hardware.
