    To have power and turn on a device you need to have both voltage and current because power=voltage*current. Thus, for example, your house main's voltage is 230V AC but the current drawn from it depends on the load you have connected on it.

    It it ends with a V, you are probably dealing with voltage ratings. Current ratings end with an A (for example, 10A) and power ratings end with a W (for example, 500W).

    Also, AC means alternate current and DC means direct current. As milk3 said, the current drawn depends on the load.
