S SKSTYLE 45W AC Adapter 19.5V 2.31A Blue Tip

This 45-watt AC adapter supplies 19.5 volts at 2.31 amps through a 4.5x3.0mm Smart Blue Tip connector. It is built for HP laptops that require a 45W or 65W barrel-style charger, including Pavilion x360, Envy, EliteBook, ProBook, Chromebook, Spectre, Stream and ZBook models. The unit accepts 100-240V input for worldwide use.

Sustained load behaviour

The adapter is rated to deliver up to 65 watts maximum output while maintaining stable voltage during continuous office work, school tasks or travel charging. A multi-protection circuit guards against overvoltage, overcurrent, short-circuit and internal overheating so the power supply runs reliably over long sessions without tripping or degrading output quality.

Replaces HP 45W and 65W barrel chargers

It directly substitutes original HP part numbers such as 741727-001, 845611-001, ADP-45FE B, PA-1450-20HL and TPN-CA04 for machines using the blue-tip barrel jack. The jump is worthwhile when the original charger is lost, damaged or no longer holds a firm connection. Not for laptops that charge only through USB-C ports.

Questions about this item

How much heat or noise does the 45 W adapter produce when it runs all day?

The unit has no fan and relies on passive cooling, so it stays silent; the multi-protection system guards against internal overheating during continuous use.

What must I already own for this charger to work with my HP laptop?

Your laptop needs the 4.5 x 3.0 mm Smart Blue Tip barrel connector; the adapter is not compatible with USB-C charging ports.

Will the 65 W rated output harm an older HP model that originally shipped with a 45 W brick?

The adapter is backward compatible and will safely deliver up to 19.5 V 2.31 A 45 W to those older models.
