In addition, it can also display the specific status of the device charging, such as whether the charging current has reached fast Charging standard, in general, it is not very useful, it is a feature that is optional.

The price of the car charger is very different. For safety reasons, it is recommended to choose a product of more than 50 yuan. It will be a little more reliable. In addition, you can refer to the five aspects mentioned above, especially to support fast charging and on-board charging.
