45W 19.5V AC Adapter for HP Laptops

This 45W AC adapter delivers 19.5V at 2.31A to power compatible HP laptops. It replaces original chargers such as part numbers 719309-001, 719309-003, 721092-001, 741727-001 and 740015-001. The unit is supplied new and ready for immediate use.

4.5x3.0mm Blue Tip Connector

The charger uses a 4.5x3.0mm barrel connector with a blue tip. This specific plug geometry is the single detail that decides whether the adapter fits the laptop. Verify the port on the device matches this exact size before ordering.

Thermals and Power Draw in Normal Use

The adapter is rated for 45W continuous output. In normal operation it runs warm but stays within standard limits for a compact laptop power supply. No active cooling is present, so keep ventilation openings clear during extended charging sessions.
