Check your laptop’s original charger label

Verify that the original power supply shows 19.5V output and a current rating of 2.31A or higher. Confirm the barrel plug measures 4.5 millimetres outer diameter and 3.0 millimetres inner diameter with a centre pin. Cross-reference your exact model number against the supported HP Pavilion and Spectre series before ordering.

Compact moulded housing with fixed cable

The adapter body is a sealed plastic enclosure meeting CE and FCC certification requirements. A permanently attached DC cable ends in the blue-tip connector, so there is no detachable tip to lose. The AC inlet takes a standard IEC C7 figure-eight mains lead, allowing easy replacement of the power cord for different regions.
