120W HP Notebook Charger

This 120 watt AC adapter delivers 19.5 volts at 6.15 amps for compatible HP Envy and Omen notebooks. It replaces part numbers HSTNN-DA25, HSTNN-LA25 and several ADP-120MH variants. The unit includes a power cord and a 4.5 by 3.0 millimetre centre-pin connector. It is a direct replacement for the original supply shipped with listed models.

Continuous 120W Output

The adapter is rated for sustained 120 watt delivery across the 100 to 240 volt input range at 50 to 60 hertz. Output voltage remains fixed at 19.5 volts while current reaches the full 6.15 amps under load. No derating or time-limited burst figure is provided in the specifications. The CE mark confirms compliance with applicable safety standards for continuous operation.

4.5mm Centre-Pin Interface

The barrel plug measures 4.5 millimetres outer diameter by 3.0 millimetres inner diameter with a centre pin. This connector fits the listed Envy TouchSmart, Envy 15, Envy 17 and Omen 15 series notebooks. Polarity and dimensions must match the device jack exactly; the adapter will not work with smaller or larger barrel sizes. Input accepts worldwide mains voltage without a separate selector switch.

Questions about this item

How much heat does the 120W adapter produce when running all day?

The adapter draws 100-240V at 50-60Hz and delivers 19.5V 6.15A continuously; typical efficiency keeps surface temperature warm but not hot under full load.

What must I already own for the 4.5 x 3.0mm plug to work?

You need a notebook that accepts a 4.5 x 3.0mm centre-pin connector and requires exactly 19.5V 6.15A input.

Will the HSTNN-DA25 part number replace the 709984-001 brick on my older ENVY 15?

Yes — 709984-001 is listed among the compatible part numbers, so the adapter fits and supplies the same 120W output.
