SMUGDESK USB4 Cable 3.3Ft 40Gbps 240W Thunderbolt 4

SKU CH-CYPM-VTC14

USB4 cable delivers 40Gbps data transfer, 240W charging and 8K@60Hz video over a 3.3Ft USB-C to USB-C link

Cable Length 3.3 Feet

  • 240W fast charging with PD 3.1 EPR support
  • 40Gbps bi-directional data transfer via USB4 Gen3x2
  • 8K 60Hz video output for high-resolution displays
  • Thunderbolt 4 compatibility for versatile device connections
  • 3ft reversible USB-C to USB-C cable design

What the cable is and who needs it

This USB4 cable delivers 40 Gbps bi-directional data transfer and up to 240 W power delivery over a 3.3 ft length. It suits users who connect Thunderbolt 4 docks, eGPU enclosures, 8K displays or high-speed SSDs to a MacBook, Steam Deck, Switch or Samsung device.

Build fit and freedoms

The reversible USB-C male-to-male plugs work with any USB-C port supporting USB4 Gen 3×2 or Thunderbolt 4. Backwards compatibility with 180 W, 140 W, 100 W and 60 W profiles means one cable replaces several lower-rated leads. PD 3.1, PPS, QC 4.0 and AFC protocols are negotiated automatically.

Capacity and headroom

Sustained 40 Gbps throughput handles 8K 60 Hz video and fast external storage without bottleneck. The 48 V, 240 W ceiling covers Apple's 140 W charger and leaves headroom for future 240 W EPR hosts. It cannot serve devices that require longer reach or proprietary connectors.

Questions about this item

Will the cable sustain 40Gbps throughput under continuous heavy data loads?

The cable is rated for up to 40Gbps bi-directional transfer with USB4 Gen3x2 devices; sustained throughput depends on the host controller and attached storage.

Does the cable become warm or draw excessive power during all-day 240W charging sessions?

It supports Extended Power Range up to 240W at 48V with PD 3.1, and is backwards compatible with 180W, 140W, 100W and 60W profiles; heat will vary with the charger and device.

Which charger and host port are required to achieve the full 240W power delivery?

A 240W EPR PD 3.1 charger and a device that accepts 240W over USB-C are needed; the cable also works with lower-power PD 3.0, PD 2.0, QC 4.0, QC 3.0, AFC, SCP and FCP sources.
