45 W AC adapter for HP laptops

This 45 W power supply delivers 19.5 V at 2.31 A through a 4.5 mm by 3.0 mm tip. It matches the original charger specifications for a long list of HP Stream, Pavilion, Envy, Spectre, EliteBook, ProBook and Chromebook models. The unit is supplied new and ready to use as a direct replacement or spare.

Barrel connector fits many HP models

The 4.5 mm by 3.0 mm barrel plug seats securely in the charging port of the compatible laptops listed by the supplier. A moulded strain relief protects the cable where it meets the connector, reducing wear from daily plugging and unplugging. The compact brick fits easily in a laptop bag without adding bulk.

Replaces lost or damaged HP chargers

If the original adapter is missing, faulty or simply left at another desk, this unit restores full charging capability without modification. It covers the same voltage and current ratings as the HP part numbers referenced in the compatibility list. Buyers needing higher wattage for larger workstations or USB-C power delivery should look elsewhere.
