SMUGDESK USB 4.0 Cable 5Ft 40Gbps 240W 8K Thunderbolt 4/3

SKU CH-1KVZ-9M998

A 5 ft USB-C cable delivering 40 Gbps data, 240 W charging and 8K video for Thunderbolt 4 and 3 devices

Cable Length 5 Feet

  • Transfers data at 40 Gbps via USB 4.0 standard
  • Delivers up to 240 W charging with PD 3.1 EPR
  • Drives one 8K 60 Hz or dual 4K 60 Hz displays
  • Works with Thunderbolt 4 and 3 hosts and peripherals
  • Backward compatible with USB 3.2, 3.1 and 2.0 devices

What this cable does

This USB 4.0 cable combines 40 Gbps data transfer, 240 W Power Delivery 3.1 Extended Power Range charging and video output in a single USB C to USB C link. It is built for owners of Thunderbolt 4 or Thunderbolt 3 laptops, docks, monitors and high-speed storage who need one lead that covers every function.

Limits of the USB 4.0 interface

The cable reaches its rated 40 Gbps and 240 W only when both host and device support USB 4.0 or Thunderbolt 4/3 with PD 3.1 EPR. Older USB-C ports fall back to 2.0, 3.0, 3.1 or 3.2 speeds and to 60 W or 100 W charging. Video output requires the source port to implement DisplayPort Alternate Mode; without it no picture appears.

The spec that decides fit

Maximum power delivery is 240 W at 48 V, with intermediate steps at 36 V / 180 W and 28 V / 140 W. If the charger or device tops out at 100 W the cable will still work but cannot deliver its peak rate. Buyers whose gear only accepts 60 W or 100 W will not see the faster charging this cable enables.

Questions about this item

Should I pick the 5-foot length or look for a shorter or longer version?

The only length offered is 5 feet, so choose this if the distance between your devices fits that reach.

What does the 40 Gbps rating deliver when the cable is plugged into my laptop and monitor?

It enables up to 40 Gbps data transfer, one 8K 60 Hz or 5K 60 Hz display, or dual 4K 60 Hz displays, provided the host supports DisplayPort Alternate Mode.

Does the USB 4.0 interface limit charging or video in any way?

The cable supports USB 4.0 and Thunderbolt 3/4 with PD 3.1 Extended Power Range at 48 V 240 W, 36 V 180 W and 28 V 140 W, so charging and video run at the full rated speeds.
