Compatible HP G42 models

This 65W AC adapter replaces the original charger for HP G42-243CL, G42-247SB and G42-301NR laptops. It delivers 18.5V at 3.5A to match the factory power specification. The unit accepts worldwide AC input from 100V to 240V at 50Hz or 60Hz. A US-standard power cord is included in the package.

Barrel connector and protection features

The output plug uses a 5.0mm internal diameter and 7.4mm external diameter barrel connector. Built-in over-voltage and over-heat protection help safeguard the laptop during daily charging. The adapter body is designed for regular transport between home, office or classroom. A two-year warranty covers the charger and the supplied wall cord.

Deciding specification: 18.5V 3.5A output

The single figure that confirms fit is the 18.5V 3.5A DC output rating. If the laptop label shows a different voltage or amperage this unit will not work. Buyers who need a higher wattage supply or a different connector size should verify their model requirements first.

Questions about this item

What voltage and current does the 65 W adapter deliver to the laptop?

The adapter outputs 18.5 V at 3.5 A, providing 65 W of DC power to the HP G42 series.

What are the barrel connector dimensions required for the HP G42 models?

The tip has a 5.0 mm inner diameter and a 7.4 mm outer diameter to match the laptop's DC jack.

How do you connect the adapter for worldwide use, and what step is often missed?

Plug the included US-standard power cord into the brick, then into a 100-240 V AC outlet; the brick auto-senses 50-60 Hz — forgetting to seat the cord fully into the brick is the common error.
