65W AC Adapter for HP Probook

This 65W AC adapter supplies 19.5V at 3.33A and is compatible with HP Probook 650, 640, 440, 450 and 445R models across G5, G6 and G7 generations. It also supports 45W requirements at 19.5V 2.31A. The unit operates on 100-240V input at 50-60Hz for worldwide use.

Installation and common issues

The package includes the power adapter, a UL listed power cord and two interchangeable barrel connectors with blue and black tips. Select the tip that fits your laptop's charging port before connecting. Incorrect tip selection is the most frequent reason the adapter appears not to work.

Practical limits of the barrel interface

Output is fixed at 19.5V with a maximum of 65W, so laptops requiring higher voltage or wattage cannot be powered. The two provided tip sizes cover the listed Probook models only; other devices with different barrel dimensions or pin configurations will not connect. The 30-day replacement window and two-year manufacturer guarantee cover defects but not compatibility mistakes.

Questions about this item

How can I verify the 65W adapter is delivering the correct 19.5V 3.33A output after plugging it in?

The adapter includes multiple smart safeguards against incorrect voltage, short circuit and internal overheating, and it is UL Listed, confirming it meets stringent safety requirements for reliable operation.

The box contains one power adapter and one UL Listed power cord; two interchangeable tips — blue and black — are fitted to the adapter so you can select the one that matches your laptop's charging port.

My ProBook originally shipped with a 45W charger — will this 65W unit work safely?

Yes, the adapter outputs 19.5V 3.33A 65W and is explicitly compatible with 19.5V 2.31A 45W models, so it will power both 45W and 65W ProBook variants without issue.
