Users needing a slimmer travel brick or a multi-tip universal charger will not find those features here.

Questions about this item

Will the 1.7 mm inner and 4.8 mm outer connector fit the charging port on my HP DV4040US laptop?

The adapter uses a 1.7 mm inner diameter and 4.8 mm outer diameter barrel connector, which matches the original specification for the HP DV4040US, DV4043ea and DV4045ea models.

How can I confirm the adapter is delivering the correct 18.5 V and 3.5 A after I plug it in?

The brick is rated for 18.5 V at 3.5 A (65 W). When connected, the laptop should show the charging indicator and the battery level should increase; a multimeter on the DC plug can verify 18.5 V under load.
