19V 90W AC/DC Adapter for HP Pavilion

This 19V 90W AC/DC adapter is built as a direct replacement for the HP Pavilion ST-C-090-19000474CT laptop. It delivers a steady 19 volt output at up to 90 watts to power the notebook and charge its internal battery. The unit is supplied new and tested for reliable operation.

The adapter accepts a universal 100-240VAC input at 50 or 60 Hz, so it works on mains supplies around the world without a voltage selector. Built-in over-voltage, over-current and short-circuit protection guards both the power supply and the connected laptop from electrical faults. A standard mains cable and DC output cord are integrated for a complete connection.
