45 W AC Adapter with 4.5 mm Plug
This 45 watt AC adapter delivers 19.5 volts at 2.31 amps through a 4.5 mm by 3.0 mm barrel connector. It accepts a universal 100 to 240 volt input at 50 or 60 hertz. The unit is designed as a direct replacement charger for compatible HP laptops.
Suitable for Listed HP Models Only
The adapter fits the extensive range of HP Pavilion x360, Envy x360, Spectre x360, EliteBook, Stream, Chromebook and standard Notebook models explicitly listed in the compatibility data. Buyers whose laptop requires a different output voltage, amperage, wattage or a different barrel connector size should look at something else.
4.5 mm × 3.0 mm Connector Decides Fit
The single specification that determines whether this is the correct part is the DC connector dimensions of 4.5 mm outer diameter by 3.0 mm inner diameter. Even when the voltage and wattage match, a different tip size will prevent a physical connection.

Questions about this item
What laptop models can use this 19.5 V 2.31 A 45 W adapter?
It fits HP Pavilion x360 15-f272wm, 15-BA009DX, 15-f233wm, 15-f387wm, HP Envy x360 15-u110dx, 11-n010dx, HP Stream 13-c077nr, 13-c002dx, HP Spectre x360 15-f039wm, 13-4103dx, EliteBook 840 G3, Folio 1040 G1, Chromebook 11 G3, G4 and many other listed models.
My older HP charger has a 4.5×3.0 mm tip — will this replacement connect the same way?
Yes, the DC plug is 4.5 mm by 3.0 mm, matching the original connector on compatible HP laptops so it plugs in directly without an adapter.
How can I confirm the adapter is delivering 19.5 V and 2.31 A after I plug it in?
The laptop charging LED should illuminate and the OS battery icon will show AC power; a multimeter on the barrel tip should read 19.5 V with no load.
