Can the car charger be left plugged in the car for a long time?

Car chargers can be left plugged in the car for a long time without affecting the car or the charger, and they pose no harm to the circuit. Car chargers use a series switching regulated power supply, and when left plugged in, the circuit automatically stops working, so it does not interfere with the circuit's operation. Car chargers are accessories designed to allow car owners to conveniently charge their digital products anytime, anywhere using the car's power supply. They are powered by the car battery and are widely used in the charging of lithium batteries for various portable and handheld devices. With the development of the automotive industry, car chargers have been widely adopted, showcasing features such as multifunctionality, portability, and stylish design.
Recently, my car has been frequently parked with the charger plugged in, so I'd like to share some experience. In theory, the car charger can be left plugged in for extended periods, but in practice, I don't recommend doing so. It's designed for plug-and-use scenarios, and even when the engine is off, it still draws a minimal amount of power, which can gradually drain the vehicle's battery. If the car isn't started for several days, a depleted battery might prevent the engine from firing up. Additionally, if the charger itself is of poor quality, its internal components may continuously generate heat, increasing the risk of short circuits or fires. I've found that choosing a certified brand, such as one with overheat protection, can help mitigate these risks. Regularly checking the vehicle's battery health is also crucial, especially for older cars that are more prone to issues. In short, for safety's sake, I've developed the habit of unplugging the charger before turning off the engine—it's convenient and requires no extra effort.
