Do i need to regulate the amps when wiring something into my car accessories plug? Answered
Hello! Excuse my ignorance if this is obvious, just like to be sure (and hopefully learn something!)
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!
