Compact black adapter with USB-C female port and 4.5x3.0mm DC barrel plug

LORDWORLD

LORDWORLD USB-C to DC 4.5x3.0mm PD 65W 18-20V Adapter

SKU CH-DMFV-0NBJ7

Converts a 65 W USB-C charger into an 18-20 V DC 4.5x3.0 mm laptop power source

  • Charges laptops from a wall outlet using a 65W USB-C charger
  • Built-in PD emulator trigger negotiates 18-20V output automatically
  • DC 4.5x3.0mm barrel tip fits many laptop power ports
  • Input accepts any 65W USB-C charger via female Type-C port
  • Output limited to 18-20V — no 5V support ensures correct laptop voltage

Purpose and user

This adapter converts a USB-C power source into a DC 4.5x3.0mm barrel output for laptops that require 18-20V charging. It is intended for owners of compatible laptops who want to use a single 65W USB-C charger instead of the original barrel-type power supply.

Build and daily use

A built-in PD emulator trigger at the USB-C female end negotiates the required voltage profile with the charger. The housing carries a fixed 4.5mm outer diameter and 3.0mm inner diameter barrel plug, so the connector cannot be swapped for other tip sizes.

Compatibility check

Confirm that your laptop charges through a 4.5x3.0mm DC jack and accepts 18V to 20V input; the adapter does not support 5V output. Ensure the USB-C charger you pair with it can deliver at least 65W, otherwise the trigger will not request the higher voltage.
