USB4 cable for 8K video and 240W charging

The SMUGDESK USB4 cable connects USB-C devices at 40Gbps and delivers up to 240W of power with a compatible charger. It supports a single 8K display at 60Hz or dual 4K monitors. The 3.3FT length suits desktop docking stations and laptop setups.

Lab-tested durability and broad device support

The cable withstands 5000 bends in laboratory testing for long-term reliability. It works with phones, accessories and gaming laptops that accept USB-C power delivery. Thunderbolt 4 and Thunderbolt 3 hosts are also supported for data and video.

40Gbps bandwidth decides fit for high-speed

The 40Gbps rating enables 2.5G files to move in one second with real-world reads up to 2.8GB/s and writes up to 2.1GB/s. Buyers who need more bandwidth for multi-stream 8K editing or faster RAID arrays should consider a higher-specification link.

Questions about this item

Will the 5,000-bend rating hold up if I coil and uncoil the 3.3FT cable daily?

The cable is lab-tested to withstand up to 5,000 bends, which covers years of typical daily coiling and uncoiling for a 3.3FT length.

Does the 40Gbps data rate stay stable during long transfers, or does heat throttle it?

The specification lists a theoretical maximum of 40Gbps with real-world reads up to 2.8GB/s and writes up to 2.1GB/s; sustained throughput will depend on the host and device thermal limits.

How warm does the cable get when delivering 240W (48V/5A) continuously?

At the maximum 240W (48V/5A) load the cable will warm noticeably but remains within USB4 thermal limits; actual temperature varies with ambient conditions and airflow.
