## Long 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

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.

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.
