Short 0.4ft USB-C to USB-C cable with flexible sheath and reinforced ends

SMUGDESK

SMUGDESK 0.4ft USB4 Type-C Cable 40Gbps 100W 8K

SKU CH-CBB9-37M8J

An ultra-short 0.4ft USB-C cable delivering 40Gbps data, 100W charging and 8K video for tidy portable setups

  • Ultra-short 0.4ft length keeps SSD enclosures and docks tidy
  • USB4 40Gbps bandwidth moves large files rapidly
  • E-Marker chip enables stable PD 100W charging for laptops
  • 8K video output connects Type-C devices to external monitors
  • Flexible sheath with reinforced strain relief withstands frequent bending

Ultra-Short USB4 Cable for Portable Gear

This 0.4ft USB-C to USB-C cable meets the USB4 specification and delivers up to 40Gbps data transfer, PD 100W charging and 8K video output. It is built for users who connect external NVMe SSD enclosures, docking stations or monitors to laptops and tablets. The compact length keeps portable setups tidy and eliminates slack that snags in bags. Backward compatibility with Thunderbolt 3 and Thunderbolt 4 ensures broad device support.

Plug-and-Play With Reinforced Ends

Installation is straightforward: connect both Type-C ends and the integrated E-Marker chip negotiates power and speed automatically. No drivers or firmware updates are required for standard USB-C, Thunderbolt 3 or Thunderbolt 4 hosts. The reinforced strain-relief collars resist damage from repeated insertion and sharp bends at the connector base. The only common issue is attempting runs longer than the fixed 0.4ft length, which this cable cannot accommodate.

Sustained 40Gbps Throughput in Tight Spaces

Under continuous heavy loads such as extended NVMe backup jobs or 8K video streaming, the cable maintains its rated 40Gbps bandwidth without thermal throttling. The flexible soft sheath dissipates heat effectively during prolonged PD 100W charging sessions. Signal integrity remains stable because the short run minimises attenuation and crosstalk. Performance stays consistent whether the cable is folded flat against a dock or bent around a portable drive.

Questions about this item

How can I confirm the cable is delivering the full 40Gbps data rate after connecting my NVMe SSD enclosure?

Check the operating system's reported link speed for the attached NVMe enclosure; it should show a 40Gbps USB4 connection when the cable, enclosure and host port all support that rate.

What comes in the box and is a power adapter included for the 100W charging capability?

The package contains only the .4ft USB-C to USB-C cable; a separate USB-C power adapter capable of 100W output must be purchased separately to enable PD 100W charging.

Should I choose this .4ft version or a longer cable for connecting a laptop to an 8K monitor?

Choose the .4ft cable only when the laptop and monitor ports are extremely close, such as on a compact docking station; otherwise select a longer USB4-certified cable to avoid tension on the connectors.
