myVolts 45W HP Notebook 15 Adapter

This myVolts 45W AC adapter supplies 19.5V at 2.31A through a 4.5x3.0mm blue-tip connector. It accepts 100-240V 50-60Hz mains input and replaces HP part numbers such as 741727-001, 740015-001 and HSTNN-CA40. The unit is sold new and carries a twelve-month manufacturer warranty.

Compatible HP 15 and 17 models only

The charger fits the extensive list of HP Notebook 15 and 17 series models detailed in the compatibility data, including 15-ba, 15-bs, 15-bw and 17-x1 variants. Buyers whose laptop requires a different output voltage, current rating or connector dimensions should look elsewhere. Units needing a higher wattage supply or an alternative tip size are not supported by this adapter.

4.5x3.0mm connector decides fit

The single specification that determines whether this is the correct part is the 4.5mm outer and 3.0mm inner diameter connector. Verify that the original adapter shows the same 19.5V 2.31A output and identical tip measurements before purchasing.

Questions about this item

Will the 4.5x3.0mm connector tip need replacing after frequent plugging?

The blue-tip barrel connector is rated for thousands of insertion cycles; under normal daily use it should last the adapter’s lifetime without needing replacement.

What limits continuous output when the adapter runs at 45W for hours?

The 19.5V 2.31A output is the hard ceiling; sustained loads at that level are constrained by the internal thermal design rather than a separate current limit.

How much heat and fan noise does the 45W unit produce on a desk all day?

There is no fan, so noise is silent; the enclosure warms to a moderate temperature typical for a 45W class adapter during continuous operation.
