65W 18.5V 3.5A AC Adapter

This 65W AC adapter supplies 18.5V at 3.5A through a 7.4mm by 5.0mm connector with a three-prong AC inlet. It is built for HP EliteBook Revolve, Folio, and ProBook models including the 810, 820, 840, 850, 725, 745, 755, 9470m, 9480m, 430, 440, 450, 455, 645, 650, 655, 250, and 255 series.

Steady 65W output under load

The unit accepts 100 to 240V AC at 50 to 60Hz and maintains a constant 65W DC output during extended charging sessions. UL certification confirms it meets safety standards for continuous operation without overheating or voltage drift.

Direct barrel-plug replacement

Installation requires only matching the 7.4mm by 5.0mm tip to the laptop's DC jack and plugging the three-prong cord into a mains socket. Buyers who need a different connector diameter or a higher wattage rating for docking stations cannot use this adapter.

Questions about this item

Does the 65W adapter run hot or make noise when powering an HP EliteBook 840 G1 all day?

The unit delivers 18.5V at 3.5A continuously; it has no fan so it stays silent and only warms slightly under full load.

What must I already own to use this 7.4*5.0mm 3-prong charger with my HP ProBook 450 G1?

You need a working AC mains lead with a standard IEC C5 socket to plug into the three-prong inlet.

Will this 18.5V supply work alongside the original 65W brick on an HP EliteBook Folio 9470m?

Yes — the voltage, current and 7.4*5.0mm connector match the factory unit, so the laptop charges identically.
