• USB QC3.0 + PD3.0 Fast Charging: Dual-port high-performance output for car charger sockets. USB QC3.0/PD3.0 fast charging: 5V/2.4A, 9V/2A, 12V/1.5A. Connects two devices for simultaneous charging, faster than traditional chargers. (Mobile phones must support fast charging and use original charging cables.)
• Temperature Measurement: The cigarette lighter voltage meter measures cabin temperature with precision from -10°C to 80°C. For accurate readings, the external temperature sensor can be folded to avoid potential direct heating/sunlight exposure.
• Voltage Monitoring: The car battery voltage meter USB charger continuously monitors vehicle voltage in real-time, preventing issues like failed starts due to voltage fluctuations. If voltage drops below 12.5V, cease using electrical devices to avoid starting difficulties. The car voltmeter is compatible with 12V-24V vehicles including cars, SUVs, trucks, and buses.
• LCD Display: The liquid crystal screen provides real-time readings of battery voltage and cabin temperature, ensuring vehicle safety. Temperature display color: green; voltage display color: red. Simply plug into the cigarette lighter socket for instant battery voltage confirmation, featuring low power consumption and high brightness.
• Safety Protection: The car charger's cigarette lighter socket incorporates a built-in fuse to prevent overcurrent, overload, overheating, and short circuits. This ensures safe daily use without damaging your vehicle. The car charger cigarette lighter socket is plug-and-play.
