现在，中国家庭拥有汽车已经不是稀奇的事了，而手机几乎也是人人都有。因手机电池的容量（期待太阳能电池手机）限制及当今软件易耗电的情况下，手机的电很容易在有限的时间内耗尽，从而给你的手机生活带来不便，那处在车途中的您在汽车上给手机充电当成了首选。
Now it's not unusual for Chinese families to own cars, and mobile phones are available to almost everyone, given the limits of cell phone batteries (which are expected to be solar cell phones) and the ease of power consumption in today's software. It's easy to run out of power in a limited amount of time, which can cause inconvenience to your mobile phone, and you'll charge your phone in the car as your first choice.
大家充电一般会简单的选择一些车载充电器，其车载充电器的原理就是把12伏的电压降到5伏后为手机充电，由于充电器的价格限制，电路有许多缺陷，电路的保护功能几乎没有，如果降压和限流电路出现故障，就会导致12伏直接进入手机，手机必死无疑。所以，我以前使用车载充电器，手机一旦在车上充了电，其手机电池存储电量越来越差，从而影响手机使用时间，最终不得不更换手机。从投资理财角度上看，这个生活必需品变成了易耗品，手机使用周期短，造成自己的生活成本提高。哪我们该如何解决手机没电，而车载充电器易损坏手机电池的问题呢？
We will choose some simple charging car charger, car charger and its principle is to 12 volts down to 5 volts for mobile phone charging, the charger price limit, circuit protection circuits have many defects, almost no, if the buck and the current limiting circuit failure, will lead directly into the 12 volts mobile phone, mobile phone will die. So, I used to use car charger, mobile phone in the car once charged, the mobile phone battery energy storage capacity is getting worse, which affect the mobile phone usage time, and eventually had to replace the mobile phone. From the investment perspective, the necessities of life into a consumable, mobile phone use short cycle due to their cost of living increase. What we do to solve mobile phone battery, car charger and mobile phone battery damage problem?
车载逆变器是选择汽车充电的一个好电子设备。其工作原理是能够将 DC 12V直流电转换为和市电相同的 AC220V交流电，供一般电器使用，是一种方便的车用电源转换器。其有输入欠压、过压保护、过温保护、输出过载、输出短路保护等电路保护功能，另外我们给手机充电时，是选择厂商提供的充电器（不是USB充电线直接插入车载充电器上），其对充电电压也有保护功能，有车载逆变器和手机原充电器双重保护手机的充电性能，我们的手机电池会得到有效的保障，从而不易担心在车上给手机充电易损坏手机电池。
The on-board inverter is a good electronic device for selecting car charging. Its working principle is that 12v DC can be converted into 220v AC which is the same as municipal power, which can be used in general electrical appliances. Is a convenient vehicle power converter. It has input under-voltage, over-voltage protection, over-temperature protection, output overload, output short-circuit protection and other circuit protection functions, in addition, we charge the mobile phone. Is the choice of the manufacturer provided charger (not USB charging line directly inserted on the car charger, it also has protection to the charging voltage, there is a car inverter and mobile phone charger dual protection of the charging performance of mobile phones. Our cell phone battery will be effectively protected, so it is not easy to worry about charging the phone in the car and damaging the cell phone battery.
但是，我们在选择车载逆变器或者手机充电器时，一定不要图一时便宜，不要选择杂牌（质量有保障）或者一些三无产品，因为有可能你表面上认为划算了，而事实上便宜的产品功能给另外一个产品的功能带来更大的损坏。从而造成更大的付出。
However, when we choose a car-mounted inverter or mobile phone charger, we must not be cheap for a while, do not choose miscellaneous (quality assurance) or some three-no products, because you may think that on the surface of the cost. In fact, cheaper product features cause greater damage to the functionality of another product.
