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

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.
