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.
