SMUGDESK USB C 4.0 Cable 40Gbps 240W PD E-Marker 1.5 Ft

SKU CH-MF0M-DZDBF

A USB-C 4.0 cable delivering 40Gbps data, 240W PD 3.1 charging and 8K@60Hz or dual 4K@60Hz video with an E-Marker chip

Cable Length 1.5 Feet

  • 40Gbps data transfer for fast SSD and dock syncing
  • 240W PD 3.1 charging powers laptops in 30 minutes
  • 8K 60Hz or dual 4K 60Hz video from one cable
  • E-Marker chip enables Thunderbolt 3 and 4 compatibility
  • 5 ft length keeps desk setups tidy

Target Devices and Use Cases

This USB-C 4.0 cable handles 40Gbps data, 240W PD 3.1 charging and 8K video in a single 1.5 Ft link. It suits owners of Thunderbolt 3/4 laptops, NVMe enclosures, docking stations and phones that support the same standards.

Sustained Load Behaviour

The E-Marker chip negotiates 48V at 240W, 36V at 180W or 28V at 140W so power delivery remains stable during long transfers or multi-monitor sessions. Data throughput stays at the negotiated 40Gbps ceiling without thermal throttling on supported SSDs and eGPUs.

Installation Notes

Plug the reversible USB-C connectors into host and peripheral; no driver install is required. The short 1.5 Ft length reduces clutter but cannot bridge distant ports, so buyers needing extra reach should choose a longer variant.

Questions about this item

Does the 40 Gbps cable generate noticeable heat when transferring large NVMe SSD files all day?

The cable carries up to 48 V at 240 W with an E-Marker chip, so power delivery is managed actively; sustained high-speed transfers stay within the rated thermal envelope.

Which ports must my laptop and monitor already have for the 8K@60 Hz video and 240 W charging to work?

Both ends need USB-C ports that support Thunderbolt 3 or 4 alternate mode and PD 3.1 Extended Power Range; the cable itself is a passive C-to-C link.

Will this 1.5 ft cable drive dual 4K@60 Hz displays from a Thunderbolt 3 dock alongside older USB 3.2 Gen 2 peripherals?

Yes, the 40 Gbps bandwidth and Thunderbolt 3/4 compatibility allow dual 4K video streams while legacy USB 3.2 devices share the same dock.
