Product information

Description

HP 394278-001 is a 65 W power adapter/inverter designed to convert AC mains input into a regulated 18.5 V DC output for compatible HP laptops and small devices. The adapter accepts standard mains frequencies of 50/60 Hz and includes power factor correction (PFC) technology to improve energy efficiency and reduce mains interference. Supplied without the mains power cord, this unit is intended as a replacement adapter, spare power supply for travel, or a workshop unit for mobile repairs.

Advantages

This adapter provides a stable 18.5 V DC output at up to 65 W to meet typical laptop power requirements while maintaining voltage regulation under normal loads. Built-in power factor correction enhances efficiency and reduces reactive current draw from the mains. Its compact external design makes it convenient to carry as a spare or replacement, and it can be used interchangeably with compatible HP equipment that requires the same voltage and power rating. No mains lead is included, allowing users to select a region-appropriate cord.

Suitable for

  • Replacing a lost or damaged HP laptop adapter with the same voltage and wattage
  • Carrying as a spare power supply for travel or remote work
  • Use in repair workshops for testing and powering compatible HP notebooks
  • Providing a regulated DC supply for compatible small electronics that accept 18.5 V input

Key specifications

  • Output voltage: 18.5 V DC
  • Maximum output power: 65 W
  • Input frequency: 50/60 Hz
  • Power factor correction (PFC): integrated
  • Connector type: barrel-style DC output (compatible with specified HP models)
  • Form factor: external AC-to-DC adapter (brick)

How to use

Connect a suitable mains power cord (sold separately) to the adapter input and plug the cord into a grounded AC mains outlet of the appropriate voltage for your region. Insert the DC output connector into the device's power socket ensuring a snug fit. Verify that the receiving device specifies 18.5 V and accepts up to 65 W before powering on. During use, keep the adapter in a well-ventilated area and avoid covering it to prevent excessive heat buildup.

Usage recommendations

Use only approved mains cords rated for your region and inspect the adapter and cables for damage before each use. Avoid exposing the adapter to liquids, extreme temperatures, or prolonged direct sunlight. For devices with battery charging, allow the adapter to operate on a stable surface and disconnect when not in use to conserve energy and extend service life.
