2.2. Versatility: the car charger is equipped with four AC replacement connectors of American regulation, British regulation, Austrian regulation and European regulation; The car charging, direct charging and USB charging are integrated to meet the charging under different conditions; Dual USB output interface, which can charge multiple electronic products.
2.3 . Fashion: for the high-end consumer group of car owners, the fashion of car charger is also valued by manufacturers. ABS material and piano paint baking process are generally used, which is not only fashionable and exquisite, but also has a very good feel.
The more high-end vehicle charger with GPS positioning function can realize the functions of real-time tracking, historical track playback, parking point query, collision alarm, overspeed alarm and geographical fence alarm. It has a monitoring platform, which can be accessed through mobile phones and computers, and provides mobile app Download for convenient positioning. For young people who like to play microblogging and self driving, a "share" button is added on the mobile phone, You can choose the driving track for a period of time to share with your friends, which is very practical.
3、 Usage of on-board charger
3.1. On the vehicle cigarette lighter, insert the USB Car Charger and output the DC voltage through the standard USB interface.
3.2. Electronic design parameters such as voltage and current fully comply with PDA mobile phone standards and will not cause damage to your beloved machine.
3.3. Connect the USB data cable to power and charge MP3 / MP4, mobile phone, small speaker, Bluetooth, PSP and other electronic products.
4、 Precautions for use of on-board charger
The car charger uses the car cigarette lighter as the power socket to directly charge the mobile phone. Due to the low voltage provided by the vehicle, the on-board charger only needs an overload protection circuit. The front end of the vehicle charger socket is designed with a safety tube. When the current exceeds the acceptable range of the overload protection circuit, the fuse will blow immediately to play a protective role. Note that the battery can only be charged when the engine is started.
Car chargers are also divided into direct charging and seat charging. You can choose to buy a seat charger, that is, remove the battery for charging, so as to avoid burning the mobile phone due to the unstable vehicle power supply and the sudden rise of voltage output peak. If you want to burn the battery, you can also burn the battery to reduce the loss. There are a variety of car chargers available on the market. If you choose online shopping, you must go to a regular website to buy.
In order to use the car charger safely, pay close attention to the following points:
4.1. The car charger should not be used under high temperature. Especially when the temperature in the car is too high in summer (generally more than 45 ℃), remember to unplug the car charger. In addition, try to avoid knocking, throwing and shaking the car charger at will during normal use, otherwise it is easy to damage the internal circuit board.
4. 2. Do not insert the vehicle charger before starting the vehicle engine, otherwise the voltage during starting may damage the vehicle charger.
4.3. Some strong cleaning agents and chemical products will cause serious corrosion damage to the vehicle filling, so be sure to pay attention when cleaning.
4.4. Remember to unplug the vehicle after the vehicle is turned off. Although the cigarette lighter of many vehicles will stop supplying power after removing the key, many cars still supply power continuously.
4.5. The vehicle charging shall also avoid water or be placed in a humid environment for a long time, otherwise the internal components are easy to be oxidized and corroded.
5、 Possible reasons for failure of on-board charger to charge
5.1. Unstable voltage during charging leads to failure of charging
5.2. The parameters of on-board charger do not meet the charging requirements
Check the output voltage and current of the on-board charger and whether it supports its own digital products. Some parameters are inconsistent. For example, if a car with an output current of 1A charges a tablet computer, it will not be charged. This is caused by insufficient current. It is necessary to replace the high-power car charger.
5.3. Poor contact of on-board charger
The contact design of some on-board chargers is unreasonable, and there will be poor contact during driving, which leads to the discovery that it is not charged after reaching the destination.
5.4. The power supply of cigarette lighter itself is abnormal
If you replace multiple on-board chargers, mobile phones, etc., you can‘t normally use the car charger for charging in your car. At this time, you should check whether there is a problem with your car fuse.
5.5. Quality problem of charger
At present, there are many brands of on-board power supply on the market, with mixed products and large price gap. If you buy fake and shoddy products, you will not only be unable to charge the power, but also be likely to burn out car fuses and digital products, and even endanger personal safety. When buying a car charger, you must pay attention to buying a safe and secure car charger.
