65 W AC adapter for HP laptops

This 65 W AC adapter supplies 19.5 V at 3.33 A through a 4.5 mm barrel connector. It is built as a direct replacement for the original charger supplied with compatible HP ProBook and EliteBook models.

100-240 V input with overload protection

The unit accepts mains voltage from 100 V to 240 V and includes overload, short-circuit, zero-voltage and under-voltage protection. Output is fixed at 65 W, so devices that require a higher wattage will not charge correctly.

Simple plug-in installation

Installation only requires connecting the barrel plug to the laptop and the IEC lead to a wall socket. The most common issue is a loose or damaged centre pin inside the laptop socket, which prevents a reliable connection.

Questions about this item

Should I pick the 65 W version or a lower-wattage adapter for my HP ProBook 640?

The 65 W unit matches the original 19.5 V 3.33 A specification, so it will power the ProBook 640 at full speed without overloading.

What does the 65 W rating mean when the charger is actually running my laptop?

It delivers up to 19.5 V at 3.33 A, giving the system enough headroom for charging while you work on demanding tasks.

Is the 4.5 mm barrel connector the standard DC jack for the EliteBook 840 series?

Yes, the 4.5 mm × 3 mm tip fits the EliteBook 840, 850 and 845 models listed in the compatibility table.
