Metal car charging or plastic car charging which is better?
As we all know, most cars now have on-board cigarette lighter sockets, and some cars also have USB charging ports, but some ports have an output current of only 500MA. Charging your phone in the car is totally unsatisfying. At this point, you need a car charger.
About metal shell car charging and plastic shell car charging, which is better?
In general, the car shell is nothing more than the difference between metal and non-metal. Metal car charger is generally aluminum alloy material, the appearance is good, but if the workmanship is not good, it is easy to leak. Non-metals are generally high temperature resistant, environmentally friendly materials, the appearance is relatively poor, but insulation. In fact, the shell has no substantial impact on the use of the function. Regardless of the material, the car shell must meet the flame retardant requirements. If there is a short circuit or other failure in the internal parts of the car charger, these dangers can also be blocked inside the product.
The metal shell of the car is completely flame retardant, and the non-metal shell of the car is relatively worrying. Generally non-metallic shell has high temperature and flame retardant ABS engineering plastics and ordinary plastics. According to the test, the positive and negative terminals of the car are short-circuited, the temperature can be as high as 95 degrees Celsius, and the plastic can be directly melted. ABS engineering plastics have good electrical insulation, are almost unaffected by temperature, humidity and frequency, and have excellent impact resistance. Car charger with metal case, the surface looks very nice. However, due to the differences in the cigarette lighter of the car, the cigarette lighter inserted into some models may cause the metal shell to conduct electricity, resulting in a short circuit of the cigarette lighter, burning the car, and insurance.
