Features: Product Usage: It can be used to supply power for phones, tablets,laptops, navigation, GPS and other most of the car products. Scope of Use: DC12-24V can be installed on car, motorcycles, ATVs, SUVs, boats and other transportation tools. Intelligent Protections: multiple protections function: input overvoltage and undervoltage protections; output over-current, over-voltage, undervoltage and short circuit protections; reverse connection protections; high temperature protections inside the chip. Features: equipped with USB+PD fast charging ports, and the fast charging protocols supported include: DCPBC1.2, QualcommQC2.0/QC3.0, fast charging protocols FCP and high-voltage SCP, fast charging protocols AFC (MAX12V), MTK PE+1.1 and MTK PE+2.0 (if the mobile phone does not support fast charging, the charger does not support fast charging protocols). Design: designed with an integrated SAE interface, which can be directly plugged into the original SAE interface, making installation more convenient. Independent Switch and Voltage Display: equipped with independent switch button, which can be used and opened immediately to avoid power consumption and easy to use; equipped with voltmeter display, which can monitor the voltage states real-time.
