65W HP Notebook Adapter

This 65-watt AC adapter delivers 18.5 volts at 3.50 amps to compatible HP notebooks and tablet PCs. It replaces original equipment part numbers such as 391172-001 and 463552-001. The unit accepts 120 V or 230 V AC input for worldwide use. Buyers needing higher wattage or a different voltage should look elsewhere.

Steady 65W Output Under Load

The adapter maintains its rated 65-watt output continuously while the connected notebook draws full power. Voltage remains stable at 18.5 V DC during extended charging and heavy workloads. No thermal throttling or ripple specifications are provided by the supplier. Users requiring detailed efficiency curves must consult the manufacturer directly.

Simple Barrel-Plug Installation

Connection is made by inserting the barrel plug into the notebook power jack until it seats firmly. Ensure the jack and plug are free of debris before connecting. The most common issue is a worn centre pin in the laptop socket causing intermittent charging. Verify the original part number matches the list above to avoid fitment problems.

Questions about this item

Does the 65 W adapter run hot or make noise when powering a laptop all day?

The unit is a compact AC-to-DC converter with no fan, so it operates silently and stays warm but not excessively hot during continuous use.

What must I already have for this 18.5 V 3.50 A adapter to work with my notebook?

You need a compatible HP notebook or tablet PC that accepts an 18.5 V DC input and uses the matching barrel connector.

Will this 65 W supply work alongside my older HP NC6320 or Pavilion dv7 that I still use?

Yes, the adapter lists the NC6320, Pavilion dv7 and many other legacy models as compatible, so it will power them without issue.
