SMUGDESK USB C to USB C Cable 3.3ft 240W Black

SKU CH-D68T-MM7HP

A 3.3 ft USB-C cable delivering up to 240 W with an E-marker chip for safe fast charging across laptops, tablets and phones

  • 240W fast charging powers devices up to 88% in 35 minutes
  • Built-in E-Marker chip with 56K ohm resistor stabilises current for safe charging
  • Universal USB-C compatibility covers laptops, tablets and phones
  • 3 ft length gives flexible reach for desk or travel use
  • 48V/5A maximum output supports power-hungry gaming laptops

What this cable delivers

This USB-C to USB-C cable supplies up to 240 W of power through a built-in E-Marker chip and a 56 kΩ resistor. The smart chip stabilises current and voltage so connected devices charge safely at the maximum rate the host allows. It is suited to anyone who needs a single cable for phones, tablets and laptops that charge over USB-C.

How it fits a setup

At 3.3 ft the cable reaches from a wall charger or power bank to a device on a desk without excess slack. The 48 V / 5 A rating means it can power a gaming laptop while leaving other ports free for data peripherals. Universal USB-C compatibility lets it serve MacBook Pro 13, iPad Pro models from 2018 to 2022, iPad Air 2020, Samsung Galaxy S-series from S8 to S22 Ultra, Pixel phones, Switch and LG handsets.

Behaviour under sustained load

The E-Marker chip maintains stable 48 V / 5 A delivery during extended charging sessions so output does not sag as the battery fills. In typical use a MacBook Pro reaches 88 % in 35 minutes, an iPad Pro 90 %, a Galaxy S22 92 % and a Switch 90 % in the same window. The cable is not intended for users who need video-out or high-speed data lanes beyond the USB-C power specification.

Questions about this item

How much power can the 240W cable sustain before the E-Marker chip limits the current?

The built-in E-Marker chip with 56K ohm resistor stabilises current and voltage up to the full 48V/5A rating, so the 240W limit is the sustained ceiling.

Does the cable get hot or draw extra power when charging a laptop at 240W for hours?

The E-Marker chip regulates voltage and current to protect the device, keeping temperature and power draw stable during extended high-wattage sessions.

Which USB-C port standard must my laptop or tablet already support to use this 240W cable?

Any USB-C device that accepts up to 48V/5A — such as MacBook Pro 13", iPad Pro 2020 or later, Samsung Galaxy S22 series, or Switch — will charge at full speed.
