FAQ
What devices can be powered by the cigarette lighter port?
The cigarette lighter port can be used for car air pumps, car refrigerators, car vacuum cleaners and other conventional cigarette lighter powered devices, as long as the power does not exceed 300W.
How does reverse protection work?
When the positive and negative poles of the battery are reversed, the inverter will automatically cut off the circuit to avoid device damage and ensure power usage safety.
Which types of batteries can it be used with?
It is suitable for common DC batteries such as 12V lead-acid batteries and lithium batteries. Please ensure the battery voltage matches the inverter's input voltage before use.
Can the peak 720W supply power continuously?
The peak power is the instantaneous maximum power, and the continuous power supply is 360W. Ensure that the device power does not exceed the rated value when using.
