Questions about this item

Does the 10 ft cable mean I receive both the AC cord and the DC lead in one piece, or must I buy a separate mains lead?

The adapter ships with a single 10 ft combined cord that includes the mains plug and the DC output connector, so no extra cable is required.

The title lists several model codes such as DSA-0421S-12142 and DSA-0421S-12 1 42 — which one identifies the unit I will receive?

All codes refer to the same 12 V 3.5 A 42 W switching supply; the version printed on the label is DSA-0421S-12142.

With a 12 V 3.5 A rating, what continuous load can this adapter reliably support inside a laptop?

It delivers up to 42 W continuous power at 12 V, matching the original charger specification for compatible laptops.
