Compatible HP Laptop Adapter

This 19V 1.58A 30W AC adapter replaces the original charger for HP models NG633EA, NG634EA, NG640EA, NG641EA, NG644EA, NG646EA and NL037PA. It accepts AC input from 100 to 240V at 50 to 60Hz for worldwide use. The unit delivers a steady DC output of 19V at 1.58A through a 4.0mm by 1.7mm connector. Buyers whose laptops require a different voltage, amperage or tip size cannot use this adapter.

Power Capacity and Limits

The adapter supplies up to 30W of continuous power, which is sufficient for charging the battery and running the supported HP laptops under normal workloads. It will not provide enough current for systems that draw more than 1.58A at 19V, so heavier gaming or workstation models are outside its capability. The 24 month warranty period covers defects in materials and workmanship during typical daily use.

Included Cable and Connector

Each package contains one AC adapter and one detachable power cord fitted with a US, UK, EU or AU plug to match the destination country. The 4.0mm by 1.7mm barrel connector ensures a secure fit on the listed HP models without the need for separate tips. No additional cables, voltage selectors or software utilities are supplied or required.

Questions about this item

Will this 19V 1.58A adapter safely run my HP NG633EA alongside its original charger?

Yes — the adapter delivers 19V at 1.58A (30W), matching the original specification for the NG633EA, so it can replace or supplement the factory unit without voltage mismatch.

How can I verify the adapter is working correctly after I plug it in?

The laptop should show charging immediately; the DC output is fixed at 19V and 1.58A, so a steady charge indicator confirms the adapter is operating as intended.

Does the box include the 4.0mm × 1.7mm tip and a mains cord for UK sockets?

The package contains one AC adapter with the 4.0mm × 1.7mm connector and one power cord; the cord supplied matches the destination country (UK, EU, US or AU).
