Stouchi 40Gbps USB4 extension cable 1.5m
Product description
This Stouchi USB4 extension cable brings high-speed data and flexible reach to USB‑C setups, pairing a 1.5m length with Thunderbolt‑grade performance for work and home use. It suits creators moving large video files, gamers routing consoles to a monitor, and anyone who needs extra reach without sacrificing transfer speed.
Key features
The cable supports up to 40Gbps data transfer and 8K@60Hz or 4K@144Hz video output according to the manufacturer. That makes it useful for moving large media projects or driving high‑resolution displays from laptops, docks or portable consoles. It also accommodates dual 4K@60Hz where host and hub permit. A reversible Type‑C connection removes fumbling when you plug in, and the 1.5m length helps keep desktop layouts tidier.

Benefits
The cable combines high transfer rates with video capability, so you can back up footage faster and drive demanding monitors without extra adapters. Its rated 240W charging support covers a wide range of chargers and devices, which helps when you need both power and data over a single lead. According to the product notes, it includes an E‑marker chip for smart current matching and tin‑plated copper shielding for reduced interference.
Getting the most from it
It’s a good fit if you need to extend a USB‑C or Thunderbolt port while keeping full bandwidth and power. If you prioritise maximum cable length for desktop-to-monitor runs, bear in mind that optimal performance is advised under a 3m total cable chain, and some hubs or displays may limit supported resolutions. Consider matching the cable with USB4 or Thunderbolt‑capable docks and chargers to unlock the full feature set.
Care & maintenance
Keep the braided jacket free of sharp bends and avoid tight loops to preserve the tested bend life. Unplug by the connector rather than pulling the cable, and store coiled loosely when not in use. The durable build aims to reduce wear, but regular inspection of connectors is sensible for long term reliability.
