19.5V 45W AC Adapter 4.5×3.0mm

This 45-watt AC adapter delivers 19.5 volts at 2.31 amps through a 4.5 mm by 3.0 mm barrel connector with a centre pin. It is designed for HP Pavilion x360 and Spectre x360 models such as the 15-f272wm, 15-f387wm, 17-g121wm and 17-g161us, plus compatible Dell units including the 15-3552. The unit accepts 100-240 V input at 50-60 Hz for worldwide use.

Check connector and voltage before ordering

Verify that your original charger shows an output of 19.5 V and 2.31 A and that its plug measures 4.5 mm outer diameter by 3.0 mm inner diameter with a centre pin. Cross-reference the part numbers on your existing adapter — examples include 719309-001, 740015-001, HSTNN-DA35 or TPN-LA03 — against the compatibility list. Buyers whose laptops require a different voltage, amperage or plug geometry cannot use this adapter.

Thermals noise and power draw

The adapter draws up to 45 watts from the mains and converts it to 19.5 V DC for the laptop. In normal operation the external casing warms moderately and the unit runs silently with no moving parts. No active cooling is present, so keep ventilation slots unobstructed during extended charging sessions.

Questions about this item

What comes in the box and do I need to buy a mains lead separately?

The adapter ships with a fixed 4.5 mm × 3.0 mm output cable and three interchangeable plug heads; no separate mains cable is required.

How do I choose the right version for my HP or Dell model?

Match your original charger’s 19.5 V 2.31 A 45 W output and 4.5 × 3.0 mm connector against the listed part numbers such as 719309-001 or HSTNN-DA35.

What does the 45 W rating mean when the adapter is powering my laptop?

It can deliver up to 45 watts continuously at 19.5 volts and 2.31 amps, so the laptop draws only the power it needs up to that limit.
