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?

They do. The adaptor has the Volts and amps it supplies printed on it just like the device has its requirements printed on it.

As long as the numbers match up, it can generally be made to work with the right connector adaptors.
