19 V 30 W Adapter with 4.0 mm Connector

This 19 V 1.58 A AC adapter delivers 30 W of power through a 4.0 mm by 1.7 mm barrel tip. It accepts 100 to 240 V input at 50 to 60 Hz and ships with a region-specific power cord. The unit is designed as a direct replacement for the listed HP part numbers.

Suitable For and Not Suitable For

This charger suits owners of the compatible HP laptops who need a new 19 V 30 W supply with the exact 4.0 mm connector. It will not work for devices that require a different voltage, a higher wattage or a different tip size. Buyers needing more power or a USB-C interface should look elsewhere.

Connector Size Decides Compatibility

The 4.0 mm by 1.7 mm barrel connector is the single specification that determines whether this adapter fits your laptop. Match this measurement and the 19 V 1.58 A output against your original charger before ordering. A mismatched tip or voltage will prevent proper operation.
