ELi5: Why do cars have a cigarette lighter charging port rather than a standard electrical outlet?

In: 4

Answer 1

Because cars used to have cigarette lighters then people started using them for power.

But also it’s a 12v dc power source not a 120v ac so it should be distinct from those used in houses.
