Of those listed, only the air-conditioner is a significant battery drain.
However, many vehicles are such configured that in order to have any amount of power available, you need to also power up the daylight running lights, fuel pump, internal computer and other consumers that quickly add up and can indeed drain a battery in a few hours. There needs to be more awareness from the car builders about the need for an eco, long lasting ignition option that you can safely use without risking battery discharge.

On almost all cars the aircon compressor is driven by the engine, not an electric motor, so the motor needs to be running to cool the air. The fan that blows the air through the vents is electric, but the air coming out will only be ambient temperature if the motor isn't running.

- nradov 8y agoWhich vehicles are those? Every car I've ever driven has had an intermediate ignition system setting which would power up the infotainment system and 12V / USB outlets but not other accessories.
