LORDWORLD USB-C to DC 4.5x3.0mm 65W PD Cable

SKU CH-RZH9-JXKT2

A USB-C to 4.5×3.0 mm DC cable delivering up to 65 W with PD and multiple fast-charge protocols

  • Charges laptops up to 65W from USB-C PD
  • DC 4.5x3.0mm barrel fits many laptop models
  • Accepts 15-20V input from PD chargers
  • Delivers 5V/2A, 9V/3A, 20V/3.25A outputs
  • Supports QC 2.0, QC 3.0, FCP, AFC, SCP protocols

Purpose and audience

The LORDWORLD USB-C to DC 4.5x3.0mm cable converts a USB-C Power Delivery source into a 4.5 mm by 3.0 mm barrel jack for laptops, tablets and phones. It targets users who want to charge barrel-jack devices from a PD charger or power bank. Buyers needing a different barrel size or a higher wattage than 65 W cannot use this cable.

Key specification

The cable accepts a USB-C PD input of 15 V or 20 V and delivers up to 65 W through the fixed 4.5x3.0 mm plug, with negotiated profiles of 5 V at 2 A, 9 V at 3 A and 20 V at 3.25 A. You must verify that your device’s rated voltage and current match one of these profiles before connecting.

Build integration

The cable plugs directly into any USB-C port that supports PD, QC 2.0, QC 3.0, DCP, PE+ 1.1, PE 2.0, FCP, AFC, SFCP, SCP or USB PD, so no extra adapter is required. It frees you from carrying the original barrel charger when a compatible PD source is available. Ensure the host charger can supply 15 V or 20 V PD; a 5 V-only source will not provide the higher voltages your device may need.
