SKU CH-5FVK-G6DP2

Converts a 6.0×1.4mm DC jack to USB-C with 140W PD charging at 5V, 9V or 20V

  • Delivers up to 140W for demanding laptops
  • Automatically switches between 5V, 9V and 20V
  • Fits standard 6.0×1.4mm DC adapters
  • Smart chip prevents overcurrent, overvoltage and shorts
  • Powers laptops, phones and tablets from one cable

Power conversion for USB-C devices

This cable converts a 6.0×1.4mm DC jack input into a USB-C output, delivering up to 140W of power. It suits users who want to run or charge USB-C laptops, phones or tablets from an existing DC power adapter.

PD voltage steps and adapter limits

The cable negotiates 5V, 9V or 20V automatically through the USB Power Delivery protocol. Actual output depends entirely on the source adapter's rating; a lower-wattage brick will limit the charge speed accordingly.

Plug orientation and fit issues

Connection is straightforward: insert the DC plug into the adapter and the USB-C end into the device. The main failure point is a loose or mismatched barrel jack, so verify the 6.0×1.4mm dimensions before use.

Questions about this item

Should I pick this 140W cable or a lower-wattage version for my 6.0×1.4mm adapter?

Choose the 140W cable if your laptop or device draws up to 140W over USB-C; the smart chip negotiates 5V, 9V or 20V automatically so it also works safely with lower-power phones and tablets.

What does the 140W rating mean when I plug this into my laptop?

It means the cable can deliver up to 140W from a compatible DC adapter to your USB-C laptop, with the built-in chip switching between 5V, 9V and 20V to match the device's negotiated power profile.

Does the 6.0×1.4mm DC jack limit the power I can actually get over USB-C?

The 6.0×1.4mm jack is the input side; the cable passes up to 140W to the USB-C output provided your DC adapter can supply that power at the required voltage.
