Questions about this item

How do I verify the adapter is delivering the 19.5V 2.31A output after plugging it in?

The laptop charging indicator should light up and the battery icon in Windows will show it is charging; a multimeter on the 4.5mm x 3.0mm tip should read approximately 19.5V.

What comes in the box and is a mains lead included?

The package contains the 45W AC adapter with a fixed 4.5mm x 3.0mm DC cable; a detachable IEC C7 mains lead for the 100-240V input must be purchased separately if you do not already have one.

Which connector size matches my Dell XPS 13 9343 — the 4.5mm x 3.0mm or another variant?

The 4.5mm x 3.0mm tip fits the XPS 13 9343 and the listed Inspiron 3000 5000 7000 models; check your original charger part number against AA45NM131 or DA45NM140 to confirm.
