The answer was provided by. If your car automatically shuts off power to any accessory items when the ignition is off, leaving something plugged into the cigarette lighter will not stop the car from shutting off. The car will still shut off if the accessory is plugged in, but it won’t turn off the engine.
If you have a car with an automatic transmission, you may be able to use a plug-in adapter to plug in an auxiliary power source. This will allow you to turn on the headlights or taillights, and then turn them off when you’re not using them. You can also use an adapter that plugs in to the passenger side of your vehicle.

What can drain a car battery when the car is off?
Interior lights, door lights, or even bad relays can drain a car battery. You don’t have to worry about the battery dying while you’re playing music because the engine runs and the alternator replenishes the battery. But when the engine is running and the car is on the road, things can get a little more complicated.
If you have a battery-powered car, you’ll want to make sure that your battery is fully charged before you start driving. You can do this by plugging your car’s battery into a wall outlet, but you can also do it the old-fashioned way — by putting it in your trunk.
How long does it take for a car battery to drain?
If you’re dealing with a fully charged battery that’s relatively new and in perfect condition, it will take 2-3 months for it to lose all of its charge. If you have an older battery, you may need to wait a bit longer. The battery’s capacity is measured in milliamp-hours (mAh), which is a measure of the amount of energy that can be stored in a given volume of space.
The more energy you can store, the longer it takes to charge the battery. For example, if your battery has a capacity of 1,000 mAh, and you charge it with 100 mA (milliamps), it would take 1.5 hours for the charge to reach 100% capacity. This means that if you use your phone for 10 hours a day, then you would only be able to use it for 2 hours before it runs out of juice.
Do USB chargers drain car battery?
Leaving things plugged in will drain the battery quicker than if you don’t. The drain will be limited by the fact that the power to the sockets will be out for a short time after you plug them in.
If you want to leave some power on, you can plug in a USB hub and use it as a power source. You can also use an external power supply, such as an AC adapter, to charge your phone.
Do phone chargers drain car battery?
Plugging your phone into a car’s USB port could stall the charging and even damage the charger. Charging your phone could even drain a car’s battery, especially if it’s an older model. Before you leave the house, it is a good idea to charge your phone at home.
What makes car battery drain fast?
Electric cars can suffer battery drain, just like conventional cars, because of extreme temperatures and damaged batteries. faulty charging is one of the reasons why your electric car’s battery might be draining. If your electric car’s battery isn’t charged, the problem could be a damaged battery.
The best way to check your battery’s charging status is to plug it into a wall outlet and wait for it to charge. You can also check the voltage of the battery by plugging it in to a voltmeter and measuring the current flowing through it. This will give you an indication of how much current is being drawn from your car battery.
The more current the more voltage you will see on the meter, and the lower the percentage of battery voltage that is actually being used by the car. For example, if you see a reading of 3.5 volts, it means that the vehicle is drawing 3 volts from its battery, but it is only using 2.2 volts of that voltage to power the engine.
Why does my car battery keep dying overnight?
Some of the most common reasons for a car battery to die repeatedly include loose or corroded battery connections, persistent electrical drains, charging problems, constantly demanding more power than the battery can provide, and over-charging.
If your battery is dead, it’s time to take it to a professional battery repair shop to have it replaced. If you don’t have access to one of these repair shops, you may be able to get a battery replacement at a local auto parts store.
