HP-compatible 90W AC adapter

This 90-watt AC adapter delivers 19 volts at 4.74 amps through a 7.4 by 5.0 millimetre barrel connector with a centre pin. It is built as a direct replacement for HP and Compaq notebooks that require this exact voltage, current and tip geometry. The unit ships new with a US three-prong power cord included.

Input range and fixed output

The adapter accepts a universal 100 to 240 volt, 50 or 60 hertz mains supply at up to 1.5 amps, making it suitable for worldwide travel with only a plug adapter. Output is fixed at 19 volts and 4.74 amps; it does not negotiate other voltages or currents. Buyers whose laptops demand a different wattage, voltage, amperage or connector size cannot use this unit.

Centre-pin 7.4 by 5.0 mm connector

The decisive specification is the 7.4 millimetre outer diameter, 5.0 millimetre inner diameter barrel plug with a central pin. Only notebooks designed for this exact tip will seat securely and communicate correctly with the charger. Verify the original adapter's tip measurements and pin layout before purchase.
