45W HP Laptop Charger with Blue Tip

This 45-watt power adapter delivers 19.5 volts at 2.31 amps through a 4.5x3mm blue tip connector. It matches HP part numbers including 741727-001, 721092-001 and 719309-001. The unit is new and built to the listed specification.

Suits owners of compatible HP Stream.

Buyers whose laptop requires a different voltage, amperage or tip size should look elsewhere. The charger is designed only for the models and part numbers shown in the compatibility list.

Output specification decides fit

The single figure that determines whether this is the correct part is the 19.5V 2.31A 45W output combined with the 4.5x3mm blue tip. Verify both values against the original adapter before purchasing.

Questions about this item

Does my laptop need a 4.5 x 3 mm blue-tip connector for this 45 W charger to fit?

Yes — the adapter terminates in a 4.5 x 3 mm blue tip that matches the DC-in jack on the listed HP Stream, Pavilion and Envy models.

Will this 19.5 V 2.31 A unit safely replace an original HP ADP-45WD B or PA-1450-36HE brick?

It supplies the same 19.5 V 2.31 A 45 W output and carries the same part numbers, so it works as a direct replacement for those OEM chargers.

How can I confirm the adapter is delivering the rated 19.5 V 2.31 A after I plug it in?

The laptop’s battery indicator should show charging, and a multimeter on the barrel plug will read 19.5 V with the centre pin positive.
