I have a hand held radio that goes through batteries far to fast and want to make a cigarette plug attachment that will use the car's battery and saves me money on buying batteries. The radio runs on 3 AAA batteries and is in series so therefore runs on 4.5V. I have no idea what the Amps are or the resistance. How would i make this adapter? I need an experts help, I'm knowledgeable enough to put it together but am unsure of how to make it!! HELP!
