[fubar]

Hey folks. I am in the midst of building a jobsite radio. I want to use a car stereo / cd player. I do realize that the car sterio runs of 12 volts, but i do not want to incorporate an over weight battery charger into this project. My question is this. What can i use to power the unit. I need to convert 120 volts ( north american ) down to 12 volts.........? can this be done cheaply, and without adding too much weight....those damn battery chargers weight a ton. Much thanks, in advance for any and / or all comments.thanks Fubar

Use a adaptor with generous rating (like 3A+). If it isn't runing too hot ...ok. U didn't gave a lot of details about the car stereo. Does it have a audio amplifier included ? U're using a external one? What power?

Why not just buy a portable player that works on 120Vac already? What advantage are you trying to gain from using a car sterio?
