If the car is on (Ignition is on, engine is running) then no.
Nothing should drain the battery when the car is running, there is a device called an alternator with a belt that usually goes around the crankshaft that transforms the mechanical energy into electrical energy. As long as you have the car running, the battery should not die. If so, you have a mechanical problem.
Yes it can, especially on older cars that aren't equipped with a battery saver program on board.
It will probably keep transmitting and place a small drain on the battery.
If you're looking for exact numbers, I don't have them, but you could easily light an entire pack without an issue while the radio is on. Neither drain a noticeable amount of battery.
If the car is left sitting for a long time and not running, yes. In some cars the cigarette lighter wont work unless the car is on for this reason.
no
It depends on whether or not the power port is on when you pull out the key.
Yes! You can buy trickle chargers that work through the cigarette lighter.
If it is lit up, then yes it will draw on the battery.
the battery is not charged wethin the car , the battery is first taken out from the car and then it is charged............. You can get a charger that plugs into the cigarette lighter and back feeds to the battery. Takes a while to charge the battery that way.
If you are talking about a car's cigarette lighter then yes if you have the proper phone adapter/charger.
