65W 19V HP Laptop Adapter

This Chicony AC adapter delivers 65 watts at 19 volts with a 3.42 amp output. It serves as a direct replacement for original HP chargers rated at 18.5V 3.5A. The unit uses a 7.4mm by 5.0mm barrel connector. It is compatible with numerous HP EliteBook, Pavilion, OmniBook and Mobile Thin models.

Plug-and-Play Barrel Connector

Installation requires only aligning the 7.4 x 5.0mm tip with the laptop power jack and connecting the US mains plug. No drivers or configuration are needed. The most common issue is selecting a charger with the wrong tip diameter or voltage for a specific model. Verify the connector size and 19V rating match the original unit before use.

65W Output for Compatible Notebooks

The 65W capacity comfortably powers the listed EliteBook, Pavilion DV and OmniBook series during typical office tasks and charging. It will run out of headroom on laptops that demand higher wattage for discrete graphics or heavy workloads. Buyers needing more than 65 watts for larger workstations or gaming notebooks should look elsewhere.
