Questions about this item

What voltage and current must the device I want to power already require for this adapter to work?

The device must need exactly 12 V DC and draw no more than 3 A, keeping total power at or below 36 W.

Will the included plug fit the 5.5 × 2.1 mm barrel jack on my older router?

Yes, the cable terminates in a 5.5 × 2.5 mm plug that also mates with a 5.5 × 2.1 mm socket thanks to the inner spring contact.

How can I confirm the adapter is delivering stable power after I plug it in?

The regulated 12 V output with low ripple means your device should power on cleanly without voltage dips or interference.
