What this charger is

The Tinkon SK90195231 is a 45W AC adapter that delivers 19.5V at 2.31A through a 4.5mm by 3.0mm blue tip connector. It accepts 100 to 240V input at 50 to 60Hz and ships with a power cord. The unit is sold new and intended as a direct replacement for compatible HP notebooks.

Who it suits and who it does not

This adapter fits a wide range of HP Pavilion, Stream, Envy, EliteBook, Chromebook and Spectre models including 14, 15 and 17 inch sizes. It matches part numbers such as L25296-001, 740015-001 and HSTNN-DA40. Buyers whose laptop requires a different connector size, a higher wattage rating or a proprietary pin layout should look at another adapter.

Behaviour under sustained load

The charger is rated for continuous 45W output at 19.5V and 2.31A from a 100 to 240V AC source. It maintains the specified voltage and current as long as the connected device draws within that limit and the mains supply stays within the input range. No thermal or duty-cycle figures are provided by the supplier.
