45W HP Laptop Charger

This 45W AC adapter supplies 19.5V at 2.31A through a 4.5mm blue tip. It is built for HP Pavilion and Stream notebooks that draw no more than 45W. Buyers whose laptops require 65W or higher cannot use this unit.

Plug-and-play replacement

The round 4.5mm connector inserts directly into the laptop power jack. No drivers or configuration are needed. The charger will not fit models that use a larger barrel or that demand more than 45W, so verifying the original part number is essential.

45W output ceiling

The adapter comfortably powers compatible 45W Pavilion and Stream systems during normal use and charging. It reaches its limit when the laptop requests more than 45W, at which point it cannot deliver sufficient current and the battery will not charge.
