As we all know, most cars now have a car cigarette lighter socket, and some cars also come with a USB charging port, but the output current of some ports is only 500mA. It is completely unsatisfactory to charge the mobile phone in the car. At this time, the car charger is needed.
Which one is better about metal shell car charger and plastic shell?
Generally speaking, the car charger shell is nothing more than the distinction between metal and non-metal. Metal car chargers are generally made of aluminum alloy, which has a good appearance, but if the workmanship is not good, it is easy to leak electricity. Non-metals are generally high temperature resistant and environmentally friendly materials, and the appearance is relatively poor. But insulated. In fact, the shell has no substantial effect on the use of functions. Regardless of the material, the car charger shell must meet the flame retardancy requirements. If the internal components of the car charger have a short circuit or other failures, these dangers can also 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 and flame-retardant ABS engineering plastics and ordinary plastics. According to the test, the positive and negative poles of the car charger are short-circuited, and the temperature can be as high as 95 degrees Celsius, and the plastic can be melted directly. ASB engineering plastics have good electrical insulation and are hardly affected by temperature, humidity and frequency, as well as excellent impact resistance. The car charger with a metal shell looks good on the surface. However, due to differences in car cigarette lighters, plugging into the cigarette lighter of some models may cause the metal shell to conduct electricity and cause the cigarette lighter to short circuit and burn the car.
