What this adapter powers

This 45 W AC adapter replaces the original charger for a wide range of HP laptops including Pavilion x360, Spectre, EliteBook and ProBook models. It delivers 19.5 V at 2.31 A through a 4.5 mm Smart Blue Tip connector. The unit accepts 100–240 V input at 50–60 Hz for worldwide use.

Connector that decides fit

The barrel plug measures 4.5 mm outer diameter by 3.0 mm inner diameter and uses HP's Smart Blue Tip centre-pin signalling. Only laptops that list this exact tip size and pin protocol will charge; models with a different barrel diameter or no centre pin will not work.

Steady output under load

Built-in overload, over-voltage and short-circuit protection keeps the 45 W output stable during continuous operation. The adapter maintains rated voltage and current without thermal throttling when powering the laptop and charging the battery simultaneously.
