What it is and who it fits

This 45W AC adapter delivers 19.5V at 2.31A through a 4.5 x 3.0mm blue-tip connector. It replaces the original charger for a wide range of HP Stream, Pavilion, Spectre x360 and ZBook models listed in the compatibility data. The unit ships new with a detachable AC power cord included.

Build fit and freedoms

The brick accepts 100-240V 50-60Hz mains input, so it works worldwide with only a plug adapter. Its 2-pin inlet keeps the cable light and the footprint small on a desk or in a bag. The fixed DC cable ends in the proprietary blue tip, removing the need for interchangeable tips or extra converters.

Sustained-load behaviour

Rated for continuous 45W output, the adapter maintains the specified voltage and current during extended charging sessions. The 1.2A maximum input draw at the AC side stays within typical household circuit limits. No active cooling is present, so the enclosure relies on passive dissipation during prolonged use.
