The inverter converts DC to AC, and the charger converts AC to DC. You use the inverter to convert the DC to AC, and then use the charger to convert the AC to DC. Actually, the loss is very large. The car cigarette lighter is 12V DC. Generally, there are two types of car cigarette lighters to USB, one type of 5V1A, one type of 5V2A, Android phones, 5V1A phones before Apple 4 can be used, Ipad and other phones only need 5V2A to enter.
Don’t select the output current. Most car chargers are capable of functioning more than two devices, and are relatively safe and reliable with overcurrent and overvoltage protection.
Car chargers and inverters have opposite principles. For example, car chargers charge digital products such as mobile phones and tablets that change AC to DC input to DC 5V.
The car inverter boosts the car power supply to an output voltage of 220V for charging home appliances, notebooks, car refrigerators, etc.
Therefore, car chargers such as mobile phones and tablets are always available in general cars, and inverters for charging home appliances are rarely used.
Now that the charger has become a must-have item, how to use the charger correctly is particularly important. Don't let the car of dozens of dollars ruin your car. Do you need to do this? If you use the car charger for a long time, try to ensure that the engine is started, because a large part of the battery power is converted from the power provided by the engine fuel. If the engine is not started, it is easy to cause low voltage and unstable equipment.
The charger has certain dangerous performance, many of the inferior products are not guaranteed, safety is not strictly tested (the chargers produced by SCIENTEK ELECTRICAL are strictly controlled, and the quality is absolutely guaranteed), many of them are unstable, or The current and voltage are unqualified and there is no current-limiting and over-voltage protection, which will damage the life of electrical appliances, and more seriously, it is unsafe for the car.
