What this charger is and who it fits

This 45W AC adapter delivers 19.5V at 2.31A through a 4.5 mm x 3.0 mm blue-tip connector with a centre pin. It is built as a direct replacement for the original power supply on compatible HP laptops.

Suits owners of listed HP models.

The unit matches HP Stream 11, 13, 14, Pavilion x360 11, 13, 15, 17, Envy, ProBook, EliteBook, Spectre and standard 14 and 15 notebooks. Buyers whose laptops require a different connector diameter, voltage or wattage should look elsewhere.

45W output covers daily workloads.

The adapter comfortably runs office applications, web browsing and media playback on supported ultraportables and mainstream notebooks. It will not sustain charging on larger workstations or gaming laptops that draw more than 45W under load.

Questions about this item

Which HP models use the 4.5 mm x 3.0 mm blue tip that this charger provides?

The adapter fits HP Stream 11, 13, 14, Pavilion x360 11, 13, 15, 17, Envy, ProBook, EliteBook, Spectre and standard 14 and 15 notebook PCs.

Can I keep using my existing HP power cord with this 45 W adapter?

Yes, the package includes a new power cord, but the adapter uses a standard IEC C5 inlet so your current cord will also work.

How do I confirm the charger is delivering 19.5 V and 2.31 A after I plug it in?

The laptop's battery indicator will show charging, and the adapter's smart chip maintains the rated output; a multimeter on the tip can verify 19.5 V if desired.
