Can a car power outlet charge a phone?

Car power outlet can charge a phone. Interface meaning: The power outlet in a car refers to the power output interface, which functions similarly to the car cigarette lighter socket. The power outlet can be used for car chargers, vacuum cleaners, car electric cups, car air pumps, and other car appliances. However, it's important to note that the maximum power of this power output socket is 180W, and exceeding this power will blow the fuse. Interface current: The car power supply can convert DC12V direct current into AC220V alternating current, which is the same as household electricity, achieving DC input and then outputting AC for general electrical appliances. The working principle is the same as that of a switching power supply, but the oscillation frequency is within a certain range. For example, if this frequency is 50HZ, the output will be AC50HZ.
You can definitely charge your phone using the cigarette lighter socket—I've been doing it in my car all the time. However, there are some details to note: Choosing a reliable car charger is crucial. I've seen too many cases of cheap ones melting the socket. The voltage conversion needs to be stable, and the output current must be sufficient. Most new car chargers now support 18W fast charging, which is three times faster than the old 5V1A chargers. Avoid prolonged charging while parked, especially in older cars where the battery might drain easily—once I forgot to unplug the charger and couldn't start the car the next day. Also, the current fluctuates significantly when starting the engine, so it's best to plug in the charger only after the engine runs smoothly, which is gentler on your phone's battery.
