90W 19V laptop charger with 5.5mm plug

This 90W AC adapter delivers 19V at 4.74A through a 5.5mm by 3.0mm DC connector. It is built for laptops that require exactly this voltage and tip size. The unit replaces a lost or damaged original charger for compatible models.

Practical limits of the barrel connector

The 5.5mm by 3.0mm barrel plug fits only devices designed for that specific centre-pin diameter. Polarity and voltage must match the laptop's requirements or the adapter will not work. Buyers who need a different tip size or a higher wattage rating cannot use this unit.
