Questions about this item

Will the 45 W output limit throttle my laptop during long charging sessions?

The adapter delivers a steady 19.5 V at 2.31 A for 45 W continuous power, so it will not throttle unless the laptop itself requests more current than the brick can supply.

How much heat or fan noise does the 45 W unit produce when left plugged in all day?

It is a passive 45 W brick with no fan, so it runs silently and only becomes warm to the touch under full load.

My laptop uses a 4.5 mm x 3.0 mm barrel tip — does this charger include the matching connector?

Yes, the fixed cable ends in a 4.5 mm x 3.0 mm barrel plug that matches the listed HP Stream, Pavilion, EliteBook, Folio and Spectre models.
