45 W AC Adapter for HP Laptops

This 45 W AC adapter delivers 19.5 V at 2.31 A through a 4.5*3.0 mm DC connector. It replaces a long list of HP part numbers including 740015-003, 741727-001 and 714149-001. The unit accepts 100 V to 240 V input at 50 Hz to 60 Hz, making it suitable for worldwide use. It is designed for HP 15, Envy TouchSmart and Pavilion Sleekbook models listed in the compatibility data.

Included Power Cable Adds Convenience

The package supplies both the AC adapter and a detachable mains cable so the charger is ready to use without sourcing a separate lead. The cable connects to the adapter's standard IEC inlet and plugs into a local wall socket. This bundling removes the need to match a cord to the adapter's input specification. Users can simply plug in and charge compatible HP notebooks immediately.

Suits Owners of Listed HP Notebooks

Buyers with an HP 15-r015dx, Envy TouchSmart 14-k047tx or Pavilion Sleekbook 14-k031tx from the supplied compatibility list will find a direct replacement. The fixed 19.5 V output and 4.5*3.0 mm tip mean the adapter cannot serve laptops that require a different voltage, current or connector size. Shoppers needing higher wattage, USB-C power delivery or a different barrel diameter should look at other models.

Questions about this item

Does the 4.5*3.0mm DC connector wear out and need replacement?

The 4.5*3.0mm barrel plug is a passive metal tip; it has no moving parts and only needs replacing if the pin bends or the housing cracks from physical stress.

What limits continuous output on the 19.5V 2.31A rail?

The adapter is rated for 19.5V at 2.31A (45W); sustained loads above that will trigger its internal protection and shut the unit down.

How hot or noisy does the brick get when left plugged in all day?

With no fan inside, the black plastic enclosure runs warm but silent; normal operation stays within the 100V-240V 50-60Hz input design limits.
