Short white cable with USB-C female connector and 4.0×1.7 mm barrel plug

Fervit

Fervit USB-C Female to DC 4.0×1.7 mm PD Cable 0.2 m 65 W 18-20 V

SKU CH-BW1K-WDTZ2

Connects a USB-C PD charger to a laptop with a 4.0×1.7 mm barrel jack, delivering 18-20 V at up to 65 W via a built-in trigger chip

  • Charges laptops from USB-C PD chargers via built-in trigger
  • Delivers 18-20 V DC through 4.0×1.7 mm barrel connector
  • Supports up to 65 W power from compatible sources
  • Compact 0.2 m cable keeps setup tidy
  • Designed for HP laptops requiring 18-20 V input

Purpose and Compatibility

This cable converts a USB-C Power Delivery charger into a 4.0×1.7 mm barrel connector for compatible HP laptops. It accepts a 65 W Type-C source and delivers 18–20 V output, making it suitable for users who want to power their barrel-jack laptop from a modern PD charger.

Upgrade Path

The adapter replaces a proprietary barrel-style AC adapter when a 65 W USB-C PD charger is already available. The jump is worthwhile for travellers or desk users who prefer carrying one compact PD brick instead of the original bulky power supply, provided the laptop operates within the 18–20 V range.

Capacity and Limits

The built-in PD trigger negotiates 18–20 V at up to 65 W, so it comfortably handles typical ultrabook and business notebook loads. It will not supply 5 V, cannot support laptops requiring higher voltage or wattage, and the fixed 0.2 m length offers minimal reach between the charger and the laptop port.
