Fervit USB-C Female to DC 4.0x1.7mm PD Cable 18-20V 65W

SKU CH-HJCG-7829K

Converts a 65 W USB-C charger into an 18-20 V DC 4.0×1.7 mm laptop power cable

  • Built-in PD trigger enables USB-C charging for DC laptops
  • Accepts 65W USB-C charger input for wall-outlet power
  • Delivers 18-20V output to 4.0x1.7mm barrel connector
  • No 5V support ensures correct voltage for laptop charging
  • Charger must exceed cable output for reliable operation

USB-C PD to DC 4.0x1.7mm adapter cable

This cable converts a USB-C Power Delivery charger into a 4.0 by 1.7 millimetre barrel output for laptops. It accepts a 65W USB-C PD source and delivers a fixed 18 to 20 volt output through the integrated trigger chip. The male DC plug fits compatible laptop power ports directly. It is intended for users who want to replace a proprietary brick with a single USB-C charger.

65W PD input with 18 to 20V fixed output

The cable negotiates 65W from the USB-C charger and presents a constant 18 to 20 volt supply at the barrel connector. It does not pass 5 volt or other low-voltage profiles, so the connected charger must support the required PD voltage. Headroom is limited to the charger’s rated 65W; devices drawing more current will not operate reliably. The fixed output suits laptops designed for 18 to 20 volt barrel input.

Replaces a proprietary 18 to 20V barrel charger

This adapter replaces the original barrel-type power supply for laptops that accept 18 to 20 volts over a 4.0 by 1.7 millimetre plug. The upgrade is worthwhile when the user already carries a 65W USB-C PD charger and wants to reduce cable count. It is not suitable for laptops that require higher wattage, different barrel sizes, or voltages outside the 18 to 20 volt range.

Questions about this item

Will the Fervit USB-C Female to DC 4.0x1.7mm cable work with my existing 65W USB-C charger?

Yes, the cable accepts a 65W Type-C charger at its female end and negotiates 18-20V output for the DC 4.0x1.7mm laptop port.

How can I confirm the cable is delivering the correct 18-20V to my laptop?

The built-in PD emulator trigger negotiates the voltage; your laptop’s charging indicator will show it is receiving 18-20V power.

What comes in the box and do I need a separate charger?

The box contains the cable only; you must supply a 65W or higher USB-C charger with Power Delivery support.
