Do i need to regulate the amps when wiring something into my car accessories plug?
I have a universal battery charger that came with an adapter to use it with car accessory plugs. That was lost long ago... I thought i would try to make a new one. I have soldered a plug that fits into the car ciggarete lighter on one end of wire, and a plug that fits into the universal battery charger on the other end. But now i wanted to make sure i don't blow up my battery charger by trying to use it :)
The bottom of the battery charger says "input: DC 12V 1 Amp". The real question is, how do i control how much amperage is going into the circuit? Or will the universal battery charger just 'pull' as many amps as it needs?
I put my multi metre in the end of the cable for the universal battery charger that plugs into the wall, and it read 2.3 amps or so. When i pocked it in the ends of the cord i wired for the car, it was reading around 9.5. Don't know if i'm doing that right any way, all help an knowledge appreciated.
Thank you in advance!
