But because of the different models of battery generator stabilizer different voltage meaning is not the same. This baby only tries to faithfully reflect the car battery voltage.Description of 3IN1 3-in-1 Thermometer: It can measure the temperature of -10~80 in the car.(2) In order to accurately measure the temperature the temperature sensor is external to the product the sensor can be bent when used to avoid the hot parts of the car that may affect the measurement results (such as the parts of the sun).Package Included:1pc x Car Cigarette LighterNote:1.
