Metal USB car charger and plastic USB car charger Which is better?

As we all know, most cars now have a car cigarette lighter interface, and some cars also come with a USB charging port, but some interfaces have an output current of only 500mA. It is completely unsatisfiable to charge the mobile phone in the car. This time, you need to use the USB car charger.

Which is better about the metal USB car charger and the plastic USB car charger? Usually, the car charger case is a distinction between metal and non-metal. The metal USB car charger is generally aluminum alloy, and the appearance is good. However, if the process is not good, it is easy to leak electricity. Non-metal is generally a high-temperature resistant material, and its appearance is relatively poor, but it is insulated. In fact, the shell has no substantial impact on the use of the function. Regardless of the material, the car charger housing must meet the flame retardant requirements. If a short circuit or other malfunction occurs in the internal components of the USB car charger, there may be a safety failure inside the product.

The USB car charger for the metal case is completely flame-retardant. The USB car charger that is not a metal case is relatively worrying. Generally, the non-metal case has high temperature resistant flame retardant ABS engineering plastic and ordinary plastic. According to the test, the USB car charger is shorted to the positive and negative poles, 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 virtually immune to temperature, humidity and frequency, and have excellent impact resistance. The metal-filled car charger looks good on the surface. However, due to the difference in the cigarette lighter of the car, it is inserted in the cigarette lighter of some models, and it is possible that the metal casing is electrically conductive, causing the cigarette lighter to short-circuit and burn out the automobile insurance.
