Replacement AC Adapter for HP Laptops

This 65W power supply replaces original HP adapters across Stream, EliteBook Folio, Split, Spectre and Pavilion x2 models. It delivers 19.5V at 3.33A through a 4.5mm by 3.0mm blue-tip connector. The unit accepts 100 to 240V input at 50 or 60Hz for worldwide use.

Fits Directly into Existing Setup

The adapter matches the voltage and current requirements of the listed HP part numbers, so it connects without extra cables or voltage converters. Its standard IEC inlet works with the included power cord or any compatible mains lead. No driver installation or firmware update is required.

Includes Mains Lead for Immediate Use

A free power cord ships in the box, removing the need to source a separate cable. The adapter is 100% OEM compatible and functions as the original part. Buyers needing a different connector size or higher wattage for other laptop families should look elsewhere.

Questions about this item

What is the continuous power ceiling before the 65 W output limit is reached?

The adapter delivers up to 65 W continuously at 19.5 V and 3.33 A, so sustained loads stay within that ceiling.

How much heat and fan noise should I expect when the unit runs all day?

No fan is present; the brick relies on passive convection and stays warm but not hot during 24-hour operation.

Which mains plug do I already need to use the included power cord?

The cord terminates in a standard IEC C7 figure-8 connector, so any C7 mains lead for your region will fit.
