90W HP Replacement Adapter

This 90 watt AC adapter delivers 19.5 volts at 4.62 amps for compatible HP laptops. It accepts 100 to 240 volt input at 50 or 60 hertz for worldwide use. The unit suits owners of listed Envy TouchSmart, Spectre x360, Pavilion and EliteBook Folio models who need a direct replacement power supply.

4.5 mm × 3.0 mm Barrel Connector

The DC plug has a 4.5 millimetre outer diameter and a 3.0 millimetre inner diameter with a centre pin, finished in blue. This specific tip size matches the charging ports on the listed HP series, so the connector seats securely without adapters. Build quality follows the original equipment form factor for daily connection and disconnection.

The adapter substitutes for the HP part numbers shown, covering a wide range of Envy, Spectre, Pavilion and EliteBook Folio systems. The upgrade is worthwhile when the original charger is lost, damaged or no longer holds a stable output. Buyers needing a different voltage, higher wattage or USB-C charging should look elsewhere.
