I didn't realize my car would come with a wireless charger so long before it arrived I went to Best Buy and purchased a USB charging cable to be kept in the car. I also have a 12 volt charger I used in the older car but I wasn't sure I would find a 12 volt outlet.
I don't normally charge my phone in the car but instead charge it at home. The ability to charge it in the car is for emergency cases where I might find myself in need of more cell phone ability than I planed for.
