At present, there are many types of on-board chargers on the market, but it is recommended to choose one with guaranteed quality, such as safe charging, power-off protection, intelligent car charging identification, etc. it is necessary to take into account, because it needs to be used when the car engine starts, no matter what product safety is the first. Don't buy a car with dozens of yuan.

As a power socket, the car lighter directly supplies power for mobile phone flat panel, intelligent rearview mirror, car vacuum cleaner, car purifier, car refrigerator and other equipment. So just buy a car charger! The conventional on-board charger used for the power supply of automobile battery (car 12V, truck 24V) can provide a variety of power supply schemes for various on-board equipment.

Vehicle charger should consider not only the actual demand of lithium battery charging (constant voltage CV, constant current CC, over-voltage protection OVP), but also the harsh environment of vehicle battery (transient peak voltage, system switching noise interference, EMI, etc.); Therefore, the power management IC of the car charging scheme must meet the following requirements: high voltage, high efficiency, high reliability, low frequency (conducive to EMI design) switching power supply chip. Generally speaking, it requires "leather solid".

When choosing a car charger, you should pay attention to the voltage and current of the supporting equipment. For example, the iPhone is 5V / 1a, and the tablet computer and mobile power supply are mostly 5V / 2A. If the dual USB interface vehicle charger charges the mobile phone and tablet computer at the same time, the total current of the vehicle charger should be at least 3A or more, otherwise the charging speed will not only drop sharply, but also overheat and even damage the device.

Car charger is an accessory for car owners to charge digital products anytime and anywhere with car charger. Some high-end car chargers generally include two USB interfaces, which can charge two digital products at the same time. This kind of products generally have overload protection, short circuit protection, high voltage input protection, high temperature protection, four safety protection functions to ensure safe use.

The car charger can be used in the car as well as in the home, realizing the multi-function of car charging, direct charging and USB charging. Car charger is an accessory for charging digital products anytime and anywhere with car power supply, which can save the cost of battery for you. This kind of products generally have overload protection, short circuit protection, high voltage input protection, high temperature protection, four safety protection functions to ensure your safe use.

If your mobile phone supports Huawei 40W fast charging, it is still recommended to buy a special car charger, such as Huawei Huawei car charger fast charging version. This product supports dual USB output, suitable for mate20 Pro Series, compatible with IOS & Android devices, with 1mtypec cable. With their own mate20 to charge, the feeling is pretty good.

Different from the traditional car charger, the 20W Xiaomi wireless car charger is a car charger that supports electric deformation and wireless charging. It is not only a cool and practical car bracket, but also a convenient and high-speed wireless charger. Xiaomi wireless car charger supports 20W Max high-power output, which can make Xiaomi 9 power quickly return to 45% in half an hour, and it only takes 90 minutes to be fully charged.

The maximum output power of single port is 18W, the maximum current output is 3.8a, and the output power of dual port can reach 36W. There is no interference when charging. Qc3.0 dual port output / intelligent temperature control / 5-fold security protection / compatible with IOS & Android. The built-in expansion interface can be connected with special expansion accessories, which can meet the needs of rear charging. The expansion line has not been sold yet.

Vehicle inverter is a kind of convenient vehicle power converter, which can convert DC12V DC into AC220V AC, which is the same as the commercial power. The most important function of MI Jia vehicle inverter is to provide AC output for portable electrical appliances. The water cup shaped magnetic dust cover is simple, safe and portable. Double USB charging port + International 5-hole combination jack, power 100W, price 199 yuan.

In the process of daily use, the car charging output current should not be greater than the maximum rated input power of the mobile phone. Otherwise, not only the charging time is slow, the device battery will be seriously hot, and the cell phone battery will be damaged for a long time. Try to unplug the car charger after the car flameout, it will damage the battery. The speed of charging depends on the voltage, not the number of connected devices. It's also necessary to avoid the habit of charging your mobile phone while navigating. How do you choose a car charger?
