HP 330W Smart AC Adapter

This 330 W power supply replaces the original charger for compatible HP laptops that require a 19.5 V DC input. It delivers the rated output through a 5.91 ft cable and accepts a 120 V AC mains connection.

Upgrade from lower-wattage adapters

A lower-wattage brick cannot sustain full performance on high-draw notebooks and may cause throttling or battery drain under load. The 330 W rating is worth the change when the original adapter is lost, damaged or no longer holds the required voltage.

Capacity and headroom

The unit comfortably powers demanding mobile workstations and gaming laptops that specify a 330 W, 19.5 V supply. It runs out when the connected device draws more than the rated output or when the AC source falls outside the 120 V input specification.
