Replacement AC adapter for HP laptops

This 45-watt power supply delivers 19.5 volts at 2.31 amps through a 4.5 by 3.0 millimetre barrel connector. It suits HP Pavilion 11, 13, 15 and X360 models, EliteBook Folio 1040 G1 through G3, Spectre ultrabook 13 and Stream 11, 13 and 14 devices. The package includes the adapter and an AC power cable.

Thermals noise and protection

The unit accepts a universal 100 to 240 volt input at 50 to 60 hertz for worldwide use. It carries CE, FCC and RoHS certifications with overcurrent, overvoltage, overload, overtemperature and short-circuit safeguards. No fan is present, so operation is silent.

Connector size decides fit

The 4.5 by 3.0 millimetre tip must match the laptop's charging port exactly; a different diameter or pin layout will prevent connection. Buyers who need a higher wattage rating or a USB-C power source cannot use this adapter.

Questions about this item

How do I install the 4.5*3.0mm connector correctly without forcing it?

Align the 4.5 mm outer diameter and 3.0 mm inner pin with the laptop port, then push straight in until it seats firmly; the step people miss is checking the centre pin is not bent before inserting.

What maintenance or replacement will the AC power cable need over time?

Inspect the cable for fraying near the strain relief and replace it if the insulation cracks; the adapter itself has no user-serviceable parts and should be swapped if output drops below 19.5 V under load.

Which protection limit activates first during sustained full-load use?

The temperature protection circuit engages before overcurrent or overvoltage thresholds, shutting the 45 W output down until the unit cools to a safe operating range.
