90W HP Laptop & All-in-One Charger

This 90W AC adapter delivers 19V at 4.74A for a wide range of HP Pavilion, EliteBook and ProBook laptops plus HP Pavilion All-in-One desktops from 18 to 23 inches. It is built for owners who need a direct replacement for the original slimline power supply. The unit is new and rated for 100 percent brand-new performance.

7.4mm Pin Connector & Power Cord Included

The package supplies the adapter and a matching AC power cable so the charger is ready to use immediately. The 7.4 by 5.0mm barrel plug has a centre pin that communicates with the laptop; without that pin the system will not charge. Verify the pin on your original tip before ordering.

Simple Plug-In Installation

Installation requires only connecting the barrel plug to the device and the IEC cable to a wall outlet. The most common issue is purchasing the wrong tip size or a version without the centre pin, which prevents the laptop from recognising the charger. Confirm your model appears in the compatibility list to avoid a mismatch.

Questions about this item

How often will the 7.4 * 5.0 mm connector with centre pin need replacing under normal use?

The barrel connector is a passive part with no moving contacts, so it typically lasts the life of the adapter unless the pin is bent or the housing is cracked during insertion.

Will the 90 W output limit be reached before the cable or connector overheats during continuous load?

The adapter is rated for a steady 19 V at 4.74 A (90 W); its internal protection shuts the unit down if temperature exceeds design limits, so the power ceiling is the first constraint you hit.

How much heat and fan noise does the 90 W brick produce when powering an HP Pavilion All-in-One 23 inch all day?

The supply has no fan and runs silently; the case warms to a noticeable but safe temperature during sustained 90 W delivery, and normal desk airflow is sufficient to keep it stable.
