65W HP EliteBook AC Adapter

This 65-watt power supply replaces the original charger for HP EliteBook 725-G3, 745-G3, 755-G3, 820-G4, 830-G5, 840-G3, 840-G4, 840-G5, 850-G3, 850-G4 and 850-G5 notebooks. It delivers 19.5 volts at 3.33 amps through a 4.5-millimetre blue-tip connector. The unit accepts 100 to 240 volts at 50 to 60 hertz for worldwide use.

Input voltage and connector constraints

The adapter only works with mains supplies between 100 and 240 volts at 50 or 60 hertz. Output is fixed at 19.5 volts and 3.33 amps, so it cannot charge devices that require a different voltage or current. The 4.5-millimetre by 3.0-millimetre blue tip must match the laptop’s charging port exactly; other tip sizes or colours will not fit.

4.5mm blue tip compatibility check

Buyers must confirm that their original HP charger uses the same 4.5-millimetre blue tip and the same 19.5-volt, 3.33-amp output. Laptops with a different connector diameter, tip colour or power rating cannot use this adapter. No other specification determines fit.
