Replacement charger for HP laptops

This 19.5 V 45 W AC adapter is built as a direct replacement for HP notebooks and Chromebooks that use the 4.5 mm blue-tip connector. It suits owners of ProBook, EliteBook Folio, Pavilion x360, Envy x360, Stream and Chromebook 11 models who need a new power supply.

Questions about this item

What input voltage range does the 19.5V 45W adapter accept?

The adapter accepts AC 100-240V at 56/60Hz, so it works on mains supplies worldwide without a voltage converter.

What connector size must the HP laptop have for this 4.5mm blue-tip adapter to fit?

The laptop needs a 4.5mm by 3.0mm barrel port; the blue-tip plug matches that exact diameter and pin size.

How do you install the adapter, and what step do people often miss?

Plug the AC cord into the brick, connect the blue-tip barrel into the laptop, then plug the mains lead into the wall — skipping the brick-to-cord connection is the common mistake.
