Replacement 45W HP Adapter

This 45-watt AC adapter replaces a lost or damaged charger for compatible HP laptops. It delivers 19.5 volts at 2.31 amps through a 4.5 by 3.0 millimetre blue-tip connector. The unit accepts 100 to 240 volt mains input at 50 or 60 hertz. A three-pin power cord is included in the package.

Upgrade From Lower Wattage

Swapping a lower-rated supply for this 45W model restores full charging speed when the original unit was 45 watts. The jump is worth it if the previous adapter could not sustain 19.5 volts under load or showed overheating protection trips. Match the blue-tip connector and 45W rating to the laptop's requirement before ordering.

Check Connector And Voltage

Verify the laptop uses a 4.5 by 3.0 millimetre blue-tip DC jack and requires 19.5 volts at 2.31 amps. Confirm the device appears in the supported model list covering Stream, Pavilion x360, EliteBook Folio 1040, Spectre, Chromebook and TouchSmart series. Ensure the mains socket accepts a three-pin plug or have a suitable adapter ready.
