  • Delivers 18 V to 20 V only — 5 V not supported
  • Works when the USB-C charger exceeds the cable's output rating

Power delivery cable for DC laptops

This cable converts USB-C power delivery into a 5.5 by 2.1 millimetre DC barrel output for laptops that require 18 or 20 volts. It targets users who want to replace a proprietary brick with a standard 65 watt USB-C charger. The built-in PD trigger chip negotiates the correct voltage automatically. It does not serve devices that only accept 5 volts over the same barrel size.

Practical limits of the PD trigger

The cable only works when the USB-C charger can supply at least 65 watts at 20 volts. Lower-power chargers will not trigger the required voltage profile, so the laptop receives no power. The output is fixed to the 18 to 20 volt range; 5 volt operation is explicitly excluded. No data or video signals pass through the connector.

Installation and common issues

Plug the USB-C charger into the female port, then connect the barrel tip to the laptop. The trigger chip handles negotiation without drivers or switches. Failures usually stem from using an undersized charger or a barrel plug with reversed polarity. Verify the laptop expects centre-positive 18 to 20 volts before connecting.
