Most cars turn off the cigarette lighter sockets when the ignition key is off. In that case, no, it won’t run the car battery down. If you have a car that leaves 12vdc to the lighter socket without the ignition key being on, then anything plugged into the outlet will consume power and yes, run your battery down.
Is it okay to leave things plugged in your car?
The LED in the charger draws a very small current. Overnight, it will not discharge the car battery enough to make a difference. The car will start fine and that will recharge the battery. If you left it plugged in for months and never ran the car, it would eventually drain the battery.

What happens if you charge a battery with too many amps?
Amperage Provided versus Amperage Required
Device may fail, may run or charge slowly, power supply may overheat, may damage the device being charged — all depending on the magnitude of the difference. The amperage provided by your charger must match or exceed what the device being charged requires.
Can a charger be too powerful?
Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.
Is 3A fast charging?
Therefore, 3A/5V charging will deliver 15W of power. One thing you’ll notice is that many manufacturers tout their ability to do a quick partial charge, such as being able to charge 50-80% of the battery within half an hour.
Is charging iPhone in car bad?
Charging your phone while on the road could drain your car’s battery, too. If you leave your car running on “accessory” — where your engine is off, but you still use the radio — the device will draw power from your car’s battery as it charges.
Can you use a cigarette lighter to play music?
This is because the cigarette lighter is, solely, a 12V power source that is connected to the battery of the car. Unlike a USB port, cigarette lighters are not connected to the stereo head unit, and therefore, cannot play music directly from the outlet.
What is USB in car for?

Can charging cables start a fire?
We would urge people to use the manufactures supplied equipment and check the chargers that they are using to ensure they are not damaged, frayed or have exposed wires, as these can all lead to a fire beginning.
Can a hot charger catch fire?
Anything can catch fire if you get it hot enough. Normally, phone chargers get a bit warm, but not hot enough to ignite. If there is an internal fault in the charger, then it can ignite.
Do more watts charge faster?
Wattage is the overall measurement of power that flows through your charger, so a higher cell phone charger wattage means that your device will charge faster.
Which is more important volts or amps?
An electrical current at 1,000 volts is no more deadly than a current at 100 volts, but tiny changes in amperage can mean the difference between life and death when a person receives an electrical shock.
