Small black adapter with USB-C female port and 7.4×5.0 mm DC barrel connector

LORDWORLD

LORDWORLD USB-C to DC 7.4×5.0 mm PD 65 W Trigger Adapter

SKU CH-M979-6JXAR

Converts a 65 W USB-C charger into an 18–20 V DC 7.4×5.0 mm laptop supply

  • Charges laptops via DC 7.4×5.0 mm port from a USB-C source
  • Built-in PD trigger negotiates 18-20 V output automatically
  • Works with any 65 W USB-C charger for wall-outlet convenience
  • Compact adapter replaces bulky proprietary power bricks
  • 5 V output not supported — ensures correct voltage for laptop charging

Compatibility & Output

This adapter converts a USB-C Power Delivery charger into an 18 V to 20 V DC barrel supply for laptops with a 7.4×5.0 mm jack. The built-in PD trigger negotiates the higher voltage profile automatically. The charger used must be rated at 65 W or higher to meet the output demand. Five-volt operation is not supported by this converter.

Who It Suits

It suits owners of legacy laptops that charge through a 7.4×5.0 mm barrel port and want to replace a bulky proprietary brick with a modern GaN USB-C charger. It is not for devices that require 5 V barrel power or tip-positive configurations outside the 18 V to 20 V range. Buyers needing simultaneous data transfer or multi-voltage negotiation should look at a full-featured dock instead.

Critical Specification

The fixed 7.4×5.0 mm barrel diameter and 18 V to 20 V output window decide fit; the laptop must accept power within that exact voltage span and use this specific jack size. A 65 W or greater USB-C PD source is mandatory because the trigger requests a high-voltage contract the adapter cannot down-convert. Without both conditions met the connector will not deliver usable charge.

Questions about this item

How do I install the LORDWORLD USB-C to DC 7.4×5.0 mm PD 65 W Trigger Adapter and what step do people often miss?

Connect a 65 W USB-C charger to the Type-C female input, then plug the DC 7.4×5.0 mm barrel into the laptop; the step often missed is confirming the charger actually delivers 65 W PD output, otherwise the trigger will not negotiate 18 V-20 V.

What maintenance or replacement will the LORDWORLD USB-C to DC 7.4×5.0 mm PD 65 W Trigger Adapter need later?

No scheduled maintenance is required; inspect the USB-C and DC connectors periodically for debris or bent pins, and replace the adapter only if the barrel becomes loose or the trigger chip stops negotiating 18 V-20 V.

What limit appears first on the LORDWORLD USB-C to DC 7.4×5.0 mm PD 65 W Trigger Adapter under sustained use?

The 65 W power ceiling is the first limit; if the laptop draws more than 65 W the charger will drop voltage or shut down, and the adapter does not support 5 V fallback.
