AC adapter HP 65W nPFC Smart 3P (model 3J448AV) – 65W laptop power supply

HP 65W nPFC Smart 3P AC adapter is a 65-watt power supply designed for compatible HP notebooks. It provides a stable 65W output for charging and operating laptops, incorporates active nPFC (near power factor correction) to improve power efficiency, and uses a three-prong AC input for reliable mains connection. The adapter is intended as a direct replacement for systems that require this HP power profile and delivers regulated DC output suitable for daily office, travel, and home use.

Advantages

The adapter delivers consistent 65W output under typical load conditions, supporting both battery charging and system operation. The nPFC feature reduces reactive power draw from the mains, improving compatibility with a range of power environments. A three-prong input provides grounding for safety and helps maintain stable connection to AC sources. The compact rectangular design balances portability and thermal dissipation for mobile usage.

Suitable for

• Charging and powering compatible HP laptops that accept a 65W input
• Office environments where continuous laptop operation is required
• Travel and remote work where a compact AC adapter is needed
• Replacing an original HP adapter with matching power specifications

Key specifications

• Output power: 65 watts
• Input: AC mains via three-prong connector
• Power conditioning: nPFC (near power factor correction)
• Output type: Regulated DC suitable for compatible notebook power ports
• Form factor: External brick-style AC adapter designed for portable use

How to use

Connect the adapter to an appropriate AC mains outlet using the supplied three-prong mains lead, then plug the DC output connector into the laptop power input until it seats securely. Ensure the laptop is powered off or in a low-activity state when first connecting if preferred, and confirm charging or power indicator lights on the laptop illuminate. Disconnect by removing the DC connector from the laptop and then unplugging the mains lead from the wall socket.

Recommendations

Use the adapter with laptops that specify a 65W power input and compatible connector type. Avoid exposing the adapter to liquids, extreme temperatures, or prolonged direct sunlight. Allow airflow around the adapter during use to prevent overheating and disconnect the adapter during severe electrical storms or when not in use for extended periods.
