New 90 W AC adapter for HP and Compaq laptops

This 90 W AC adapter is a new replacement power supply for HP and Compaq notebooks. It delivers 19 V at 4.74 A through a 7.4 mm by 5.0 mm DC connector. The unit suits owners of compatible Pavilion, EliteBook, Presario, Mini and HDX models who need a direct replacement.

Operates on 100 to 240 V mains worldwide

The adapter accepts input from 100 V to 240 V at 50 Hz or 60 Hz, drawing up to 1.5 A. This range covers standard mains supplies in most countries without a separate voltage selector. A suitable AC mains cable for the local wall socket is required to complete the connection.

Connector size decides compatibility

The DC plug measures 7.4 mm outer diameter by 5.0 mm inner diameter. Only laptops that use this exact barrel size and the 19 V 4.74 A rating will work correctly. Buyers with devices needing a different connector diameter, pin arrangement or power rating must choose another adapter.
