19.5V AC Adapter for HP ProBook 450 G3 and 455 G3

This 19.5V AC adapter replaces the original charger for HP ProBook 450 G3 and 455 G3 laptops. It supplies the correct output voltage and includes the mains power cord. The unit is brand new and built to match the laptop's power requirements. It is intended for owners of these specific models who need a direct replacement.

Replaces a lost or faulty original charger

The adapter serves as a direct substitute when the factory charger is missing, damaged or no longer holds a stable output. The upgrade is worth it when the existing unit shows intermittent charging, physical cable wear or complete failure. It restores full charging capability without modifying the laptop. Buyers who need a higher wattage rating or a different connector type cannot use this model.

Stable output with built-in protection circuits

Under sustained load the adapter maintains a steady 19.5V output while the laptop charges and runs simultaneously. Integrated over-voltage, over-current and short-circuit protection circuits guard both the power supply and the notebook during extended sessions. The wide 100-240VAC input handles global mains voltages at 50/60Hz without manual switching. The unit is designed for continuous daily operation.
