Questions about this item

How much heat does the 45W 19.5V adapter produce when running all day?

The unit draws 1.5 A at 100-240 V input and delivers 19.5 V at 2.31 A, so typical efficiency losses appear as modest warmth rather than hot surfaces.

What must I already own to use this charger?

You need a standard IEC C7 or C5 mains lead for the AC 100-240 V inlet and an HP laptop with a 4.5 mm × 3.0 mm blue-tip DC jack.

Will the 4.5 mm blue tip fit the HP Pavilion x360 13 I keep as a spare?

Yes, the 4.5 mm × 3.0 mm blue-tip connector matches the Pavilion x360 13 and other listed models such as Envy x360 13 and ZBook 14u G4.
