Check Connector and Polarity Before Ordering

Verify that your original supply lists 12 V output and a current rating between 3.5 A and 4 A. Confirm the barrel plug size, centre-positive polarity and the 10 ft cord length suit your device and workspace layout.

The adapter serves as a drop-in substitute when the original charger is missing, damaged or no longer holds regulation. The upgrade is worthwhile when your existing unit shows intermittent charging, overheating or physical cable wear.

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.
