What this adapter powers

This 45W 19.5V 2.31A AC adapter replaces the original charger for a wide range of HP Stream 11 13 14 x360 Spectre x360 Pavilion x360 and 15 series notebooks. It accepts 100-240V 50/60Hz input and delivers power through a 4.5mm x 3.0mm connector.

How it fits your setup

The unit plugs directly into a wall outlet and connects to the laptop barrel jack so no dock or extra cable is required. Its universal voltage input lets it work worldwide and the compact brick leaves desk space free for other peripherals.

When the upgrade makes sense

Choose this adapter when the factory charger is lost damaged or no longer holds a stable 19.5V output. It is not suited for larger HP models that demand higher wattage or a different connector size.

Questions about this item

Will the 45 W output limit performance during long work sessions?

Does the brick get hot or make noise when left plugged in all day?

No fan or moving parts are present; the unit runs silently and warms only to normal operating temperature for a 45 W switch-mode supply.

Which connector does my laptop need to accept this charger?

A 4.5 mm × 3.0 mm barrel plug — the same centre-positive tip used on the HP Stream 11, 13, 14 and compatible Pavilion x360 units.
