    The 12v relay usually means it requires 12v to switch it on and off.
    You will have to check the load specs on the relay to see what it can handle.

    Many 12vDC relays are used to switch 240vAC or more.

    The main reason for using a relay is because you need to switch a different type of power than you are using.

    If they are both 12v you dont need a relay. But if you want to use it anyway, just make sure to read the datasheet for the relay you are getting to be sure it is capable of switching the amperage you need for the load.
