So, your three amp power supply can provide 3 amps forever because it is connected to the mains. Your battery has a limited amount of chemicals to produce electricity with and so is rated by amp hours, so you can figure out how long you should be able to run a device on it. Amps and amp hours, while related are two different things.

Thank you. Okay, but taking it one more step, does the 3.0 amp rating of the ARBE III battery eliminator have any importance to the operation of the radio? What would be the advantage/disadvantage if it was say 12 or even 20 amps? Just so curious to know and understand what that amp value in the eliminator means to the user.
