With the increase in car ownership each year, cars have become the second home for most people. Since you are at home, it is inevitable to charge digital devices such as mobile phones. As we all know, most cars now have a car cigarette lighter socket, and some cars also have a USB charging interface, but the output current of some interfaces is only 500mA. It is completely unsatisfactory to charge the mobile phone in the car. At this time, a car charger is needed.

Which metal car charger and plastic car charger do you choose?

If you have ever purchased a car charger, you will surely find that there are two types of car chargers on the market today: metal and plastic. Which is better about metal case car charger and plastic case car charger? Generally speaking, the car charger shell is nothing more than the difference between metal and non-metal. Metal car chargers are generally aluminum alloys with beautiful appearance. However, if the process is not good, it is easy to leak electricity. Non-metals are generally high temperature resistant environmental protection materials. But insulated. In fact, the shell has no substantial impact on the use of functions. Regardless of the information, the car charger housing must meet the requirements of flame retardancy. If the internal components of the car charger have a short circuit or other problems, there are also risks that can be blocked inside the product.

Car chargers with metal casings are completely flame-retardant, while car chargers with non-metal casings are relatively worrying. Generally, non-metal casings have high temperature resistant flame retardant ABS engineering plastics and general plastics. According to the test, the positive and negative poles of the car charger are short-circuited, the temperature can reach 95 degrees Celsius, and the plastic can be directly melted off. ASB engineering plastics have good electrical insulation, and are almost unaffected by temperature, humidity, and frequency. They also have excellent impact resistance. The full-metal shell of the car charger looks good on the surface, but because there are differences in car cigarette lighters, plugging in the cigarette lighter of some models may burn the car because the metal shell conducts electricity, forming a short circuit of the cigarette lighter.
