HP-compatible 45 W power supply

This 45 W AC adapter delivers 19.5 V at 2.31 A through a 4.5 mm × 3.0 mm barrel connector. It matches the original charger specification for HP Pavilion 11, 13 and 15 models, X360 convertibles, EliteBook Folio 1040 G1 to G3, Spectre ultrabooks and Stream 11, 13 and 14 devices.

Thermals, noise and power draw

The unit accepts 100–240 V AC at 50–60 Hz, making it suitable for worldwide mains voltages. CE, FCC and RoHS certifications cover over-current, over-voltage, overload, over-temperature and short-circuit protection. No moving parts mean silent operation and minimal heat during normal charging.

Build integration

A detachable AC power cord is included in the package so only a standard wall socket is required. The fixed 4.5 mm × 3.0 mm tip plugs directly into the listed HP laptops without adapters. Buyers needing USB-C Power Delivery or a different barrel size should look elsewhere.

Questions about this item

How do I connect the 4.5mm × 3.0mm barrel plug to my HP Pavilion 13 X360 without bending the centre pin?

Align the plug straight with the DC jack, push it in until it seats with a soft click, and route the cable so the adapter brick hangs freely rather than pulling sideways on the connector.

When should I replace the AC power cable that ships with the 45W adapter?

Swap the IEC C7 mains lead if the insulation cracks, the plug pins loosen, or the cable gets warm near the connector during normal 19.5V 2.31A charging.

At what point does the over-temperature protection trip during continuous 45W load?

The internal thermal cut-out activates when the adapter case exceeds its safe operating limit, shutting output off until the unit cools down.
