After using this HP 65W charger for a month with my HP Elitebook 840, I can confidently say it's a solid replacement for OEM chargers.

The blue-tipped connector fits snugly into my laptop without any wobbling - a big plus when working at coffee shops where cords often get bumped.

Charging speed is identical to my original HP charger. My dead battery reaches 80% in about an hour, which is perfect when I'm rushing between meetings.

What surprised me most was how cool it runs. Even after 4+ hours of continuous use, the brick stays barely warm to the touch - much better than some third-party chargers I've tried.

The 6-foot cord is generous, though I wish it had a right-angle connector option for better cable management on cramped desks.

At less than half the price of HP's official charger, this delivers exceptional value. It's become my permanent office charger while keeping the OEM one in my travel bag.
