Genuine HP 150W AC adapter for compatible notebooks

This genuine HP HSTNN-DA27 adapter delivers 150 watts at 19.5 volts and 7.7 amps for notebooks that require this exact output. It replaces a lost or damaged original charger and restores full charging speed. The unit accepts worldwide mains voltage from 100 to 240 volts at 50 to 60 hertz.

Tested unit with included power cord and safety

Each adapter is tested for correct voltage, secure jack operation and intact cables before shipping. The body may show minor cosmetic marks that do not affect function. Built-in safeguards protect against incorrect voltage, short circuit and internal overheating during daily use.

Direct replacement for the same HP part number

This matches HP part number 645509-002 and the HSTNN-DA27 model exactly. It is not suitable for devices that need a different voltage, amperage or connector type. Buyers who need a higher wattage unit or a USB-C power delivery adapter should look elsewhere.
