DC 12v question
So I know that when I had my MaxxAir fans installed the dealer just tapped into a nearby light in the ceiling. With that said, my question now is, I'm looking to tap into the nearby 12v cigarette plug to wire in a 12v TV, and am wondering if I do that, will I still be able to plug something into that cigarette lighter plug (like a phone charger) to charge, or will the draw be too much and potentially melt wiring?
How do I guage when tapping into the 12v DC wiring how much is safe and when to back off?
