Compatible HP Omen Models

This 150 W AC adapter replaces the original charger for HP Omen 15-ax256nr and 15-ax257nr notebooks. It delivers 19.5 V at 7.7 A and accepts worldwide input voltage from 100 to 240 VAC at 50 or 60 Hz. The unit includes a 10 ft power cord for flexible placement.

Replacing A Lost Or Faulty Charger

The adapter is a direct replacement when the original power supply is lost, damaged or no longer charges the battery. Built-in protections cover over-current, over-voltage, short-circuit and total power events, while a smart chip adds overheat and over-charge safeguards. FCC, CE and RoHS certifications confirm compliance with safety standards.

Check Connector And Voltage Before Ordering

Verify that your laptop requires a 19.5 V 7.7 A input and uses the same barrel connector as the original HP Omen charger. The 10 ft cord length suits most desk setups but confirm it reaches your mains outlet. This adapter is not for buyers who need a different voltage, a higher wattage unit or a USB-C power delivery solution.

Questions about this item

What connector does the adapter use to fit the HP Omen 15-ax256nr and 15-ax257nr?

The adapter is built as a direct replacement for those models, so its output plug matches the original HP Omen 15-ax256nr and 15-ax257nr charging port.

How do I install the adapter, and what step is often missed?

Plug the 10 ft mains cable into a 100-240VAC 50/60 Hz socket, connect the output tip to the laptop, and ensure the brick rests on a flat surface so its overheat protection can work.

When will the adapter or its cable need replacement?

The unit carries FCC, CE and RoHS certification and a 12 month warranty; replace it if the 10 ft cord shows wear, the brick overheats, or output drops below 19.5V 7.7A.
