An external power supply can be connected, but the machine itself must have an interface for the external power supply.
Solar car air purifiers are used to purify the air in the car and can remove odors and some harmful gases in the car.
Car air purifiers can be divided into solar car air purifiers and externally powered car air purifiers according to the electricity source.
The power source of the vehicle-mounted solar air purifier is to convert thermal energy into electrical energy via solar panels through sunlight, and then supply it to the internal battery and to the motor for the operation of the machine.
The air purifier with external power supply uses the car's power supply to provide power to the purifier.
Whether it is a solar air purifierCar-mounted or an air purifier with external power supply, the filter element should be replaced in time, otherwise it will cause secondary pollution.
Rechargeable car purifiers are better, because for solar powered purifiers, first of all, the charging efficiency of solar panels is very low, and the car is basically covered with a film of sun protection, so solar energy efficiency is even lower. Additionally, if you have solar panels, you must have batteries. Some batteries may explode at high temperatures and their safety cannot be guaranteed. I personally recommend Newman's new car purifier, which can detect air quality and see the air quality in the car for peace of mind. I hope this helps you.
