45W HP-Compatible AC Adapter

This 45 watt power supply delivers 19.5 volts at 2.31 amps for HP laptops that use the 4.5 by 3.0 millimetre blue-tip connector. It suits owners of Pavilion x360, Spectre x360, EliteBook Folio, Stream and Envy models listed in the compatibility data.

Thermals and Protections

The adapter includes overheating protection and short-circuit protection to guard the unit and the connected notebook. It operates from a 100 to 240 volt, 50 or 60 hertz mains supply with a 1.3 amp input rating and a three-pin IEC inlet.

Decisive Specification: Blue Tip Connector

The 4.5 by 3.0 millimetre blue-tip plug is the single detail that decides fit; only laptops requiring this exact connector will work. Buyers whose devices use a different tip size or colour cannot use this adapter.

Questions about this item

How do I connect the 4.5*3.0mm blue-tip connector to my HP laptop?

Align the blue tip with the charging port and push straight in until it seats firmly; the step users miss is verifying the tip colour matches the port before applying force.

When will the 45W adapter need replacement under daily use?

The unit carries an 18-month manufacturer exchange period; plan to replace it once the overheating or short-circuit protection activates repeatedly.

What is the first limit reached during continuous 19.5V 2.31A output?

Sustained 45W delivery triggers the built-in overheating protection, which shuts the adapter down until it cools.
