Replacement 30W AC Adapter

This 19V 1.58A adapter replaces the original charger for HP models NJ209LA, NL037PA, NL037PAR, NL038PA, NL039PA, NG645EA and NG646EA. It delivers 30W through a 4.0mm by 1.7mm barrel connector and includes a region-specific power cord. The unit accepts 100 to 240V input at 50 to 60Hz for worldwide use.

Upgrade From Damaged Or Lost Unit

The adapter is a direct substitute when the factory charger fails, is misplaced or shows worn cables and intermittent charging. It matches the required 19V output and 1.58A current so the laptop draws the same power as before. Buyers whose device needs a higher wattage or a different connector size should look elsewhere.

30W Capacity For Compatible Laptops

At 30W the supply comfortably runs and charges the listed HP notebooks under normal workloads. Heavy GPU or CPU loads that exceed this power envelope will drain the battery even while plugged in. The 24-month warranty period covers defects in materials and workmanship.

Questions about this item

What size is the DC connector on this 19V 1.58A 30W adapter?

How do I connect the included power cord to the adapter for the first time?

Plug the cord into the adapter's IEC C8 inlet until it clicks, then insert the wall plug; the step often missed is seating the cord fully before powering on.

Replace the unit if output drops below 19V 1.58A, the cord shows exposed wires, or the adapter becomes excessively hot during normal 30W load.
