1. The USB charging port current of the vehicle itself is only 0.5A, while the current demand of the driving recorder is generally above 1A, so it is necessary to match the corresponding vehicle charging output current.

If a car mounted charger adapter is used to plug in the dash cam, it can meet the current requirements of the dash cam, but it is necessary to choose a suitable car charger to avoid charging problems caused by insufficient or excessive current.

2. It is recommended to use a car charger called "Red Orange", which can automatically recognize the current demand of the dash cam, automatically adjust the output current of the car charger, and provide the most reasonable charging plan based on this, effectively avoiding charging problems.

In short, if you want to use a Car mounted charger adapter to plug in the dash cam, you need to choose an adapter that matches the current of the vehicle's charging port, and choose a suitable car charger to avoid charging problems caused by insufficient or excessive current.
