Replacement 120W Adapter for HP Slim 4.5mm

The WAWEIS 120W AC/DC adapter replaces the HP ADPTR 120W S-3P PFC Slim charger with a 4.5mm barrel connector. It delivers 100-240VAC 50/60Hz worldwide input voltage and matches original OEM specifications. The unit is brand new and fully compatible with listed HP laptop models. Total power cord length reaches 10 ft for flexible placement.

Sustained Load Protection Features

Under continuous operation the adapter maintains stable output through multiple safety layers. Over current protection, total power protection, over voltage protection and short circuit protection activate automatically during extended charging sessions. Smart chip overheating protection and anti-interference isolation materials further guard against thermal stress. High quality wires and strict quality control support reliable long-term use.

Upgrade from Damaged or Lost Original Charger

This adapter replaces a failed, lost or worn-out factory charger without changing laptop behaviour. The jump is worth it when the original unit no longer holds a secure connection, shows cable damage or cannot maintain full charge under load. FCC, CE and RoHS certifications confirm compliance with the same standards as the original supply. Buyers needing a different barrel size or higher wattage should verify their laptop requirements before ordering.

Questions about this item

How much heat or noise does the 120 W adapter produce when running continuously?

The brick has no fan and relies on passive cooling; the supplier lists over-heating protection and a smart chip to keep temperatures in check during all-day use.

What must I already own to use this 4.5 mm charger?

You need an HP laptop that accepts a 4.5 mm barrel connector and draws up to 120 W; the unit includes a 10 ft mains cord so no separate cable is required.

Will the 732811-001 adapter work alongside an older HP power supply I keep as a spare?

Yes — both bricks share the same 4.5 mm tip and 100-240 V input, so you can swap them without changing cables or settings.
