45W AC adapter 4.5mm connector

This 19.5V 2.31A AC adapter delivers 45W of power through a 4.5mm connector for compatible HP laptops. It accepts universal AC input from 100V to 240V at 50Hz or 60Hz. The package includes the adapter and a detachable power cord. It carries CE certification for safety compliance.

Steady 45W output under continuous load

The adapter maintains its rated 45W output during extended charging sessions without thermal throttling. Voltage regulation stays within specification across the full input range. The unit runs cool enough for desk or travel use. No fan noise is produced during operation.

Replaces original HP 45W chargers

This unit replaces lost or damaged HP adapters with part numbers such as 719309-001, 741727-001, HSTNN-CA40 and ADP-45WD B. It fits HP Stream, Spectre, Envy and Pavilion models listed in the compatibility data. The jump is worth it when the original charger fails or a spare is needed for travel. It does not serve laptops that require higher wattage or a different connector size.

Questions about this item

Does the 45 W adapter run hot or make noise during all-day use?

The 45 W unit is passively cooled and has no fan, so it stays silent; normal warmth is expected when delivering 2.31 A continuously.

What must I already own to use the 4.5 mm barrel connector?

You need a compatible HP laptop that accepts a 4.5×3.0 mm tip and a standard IEC C7 mains lead for the AC inlet.

Will the 100-240 V input work with my older 110 V travel socket?

Yes, the adapter auto-ranges from 100 V to 240 V at 50-60 Hz, so it operates on legacy 110 V circuits without a voltage switch.
