Genuine Dell 90W OEM replacement adapter

The Dell HA90PM180 is a genuine 90W OEM AC power adapter built for Dell Latitude, Inspiron, Precision and XPS laptops that require a 19.5V supply with a 7.4mm barrel connector. It replaces part number 90YP3 and restores factory charging performance. Buyers needing a higher wattage unit or a USB-C power source cannot use this adapter.

Universal input 100240V for worldwide compatibility

The adapter accepts a universal 100240V input range, allowing it to operate on mains supplies around the world without a separate voltage selector. Integrated surge and short-circuit protection guards the laptop and the brick during prolonged charging sessions. The compact black enclosure is designed for daily transport and long-term reliability.

7.4mm barrel tip connector decides fit

The single specification that determines compatibility is the 7.4mm barrel tip paired with a 19.5V 4.62A output. Only Dell models explicitly listed for this connector and voltage will charge correctly. Verify the laptop's original adapter tip size and voltage before purchase.
