How do you tell which AC adapter goes with which device?

Question

If the device says something like “DC-12V-IN”, will any 12V AC adapter with the correct connector work?

And why don’t they mark the adapter somehow so it’s obvious which device it goes with?

The correct voltage is one part. You’ll also want to see how many amps the device will draw and make sure the adapter can deliver at least that number of amps.
