The Mi 50w car has a fan.
It is not recommended to use a fan if you are sensitive to the wind.
Wire charging is strongly recommended for fast charging.
If you don't care about speed, buy one without a fan.
If you consider using mobile phones, some time later our company's products will be listed, there are still many advantages, such as the charging speed is the fastest in the non-millet original while the temperature is significantly lower than the millet original.
