SMUGDESK 240W USB4 Cable 1.5FT

SKU CH-0YSN-9FQQT

A 1.5 ft USB4 cable delivering up to 240 W charging, 40 Gbps data and 8K at 60 Hz over Thunderbolt 4

Cable Length 1.5 Feet

  • Charges a MacBook Pro in under an hour with 240W power delivery
  • Transfers data at up to 40Gbps when both devices support the speed
  • Drives an 8K display at 60Hz or two 4K screens using separate cables
  • Works with Thunderbolt 4, Thunderbolt 3 and USB 3.2, 3.1, 3.0 hosts
  • Compact 1.5FT length keeps a desk setup tidy

What this cable does

This USB4 cable carries up to 240W of power at 48V and 5A, delivers data at 40Gbps and drives an 8K or 5K display at 60Hz. It is built for users who need a single short link between a host and a high-power charger, dock or eGPU.

Thermals noise and power draw

The cable itself generates no audible noise and draws no power beyond what the connected devices negotiate. In normal use it simply passes the 240W charging current and 40Gbps signal without adding measurable heat to the setup.

Sustained load behaviour

Under continuous maximum power delivery and full-rate data transfer the cable maintains the rated 240W and 40Gbps without throttling. It is not intended for runs longer than 1.5FT or for daisy-chaining multiple high-bandwidth peripherals on a single link.

Questions about this item

How do I connect the 1.5FT cable to get 240W charging and 40Gbps data?

Plug the USB C connectors firmly into both host and device ports; the step many miss is confirming the charger and device both support 48V/5A and 40Gbps, otherwise the cable falls back to lower power or speed.

What wear should I watch for on this Thunderbolt 4 compatible cable?

Inspect the USB C plugs for bent pins, cracked housing or frayed strain relief; if the cable no longer negotiates 240W or 40Gbps, replace it.

When does the 1.5FT length limit 8K@60Hz or 40Gbps during long sessions?

The 1.5FT passive design meets USB4 signal specs, so sustained 8K/6K@60Hz and 40Gbps hold as long as both ends stay within thermal limits; overheating at the source or sink is the first practical ceiling.
