  • 240W charging powers a gaming laptop at 48V/5A
  • 88% MacBook Pro charge in 35 minutes
  • 92% Samsung Galaxy S22 charge in 35 minutes
  • 480Mbps USB 2.0 transfers 1GB in 30 seconds
  • E-marker chip with 56K resistors protects devices during charging

What this cable does and who needs it

This USB-C to USB-C cable delivers up to 240W of power with Power Delivery support. It suits users who need fast charging for laptops, tablets, phones or a Switch from a single cable. The 3.3 ft length keeps desk setups tidy while reaching nearby outlets or hubs. It does not carry a video signal.

Build fit: power and data in one lead

The cable replaces a separate charger and data lead, freeing a port on your charger or dock. It handles 480Mbps USB 2.0 transfers, moving roughly 1GB of files in about 30 seconds. An E-marker chip and 56K resistors negotiate the correct current automatically, so the host and device agree on safe power levels without extra configuration.

Thermals, noise and power draw

Passive construction means no fan noise and no active cooling required. The aluminium-braided jacket dissipates heat from the conductors during sustained 48V/5A loads. In normal use the cable stays cool to the touch and adds no audible noise to the system. Power draw is determined entirely by the connected device and charger.

Questions about this item

Does the 240 W rating hold steady during a long charging session?

The cable uses an E-marker smart chip and 56 K resistors to match the required current and maintain smooth conduction while delivering up to 48 V at 5 A.

How much heat does the cable generate when it runs at full load all day?

The aluminium braided jacket helps dissipate heat during sustained 240 W power delivery, keeping the cable cool to the touch.

What must my laptop or charger already support for this cable to deliver 240 W?

Both the power source and the device need USB Power Delivery capable of 48 V at 5 A; the cable itself handles up to 240 W.
