The battery capacity of a car is about 60ah (more if it is an electric car), and the 200w car inverter consumes about 15A per hour. Generally, the maximum consumption of a car battery is 50%. When we ignore the working efficiency of the inverter and other losses, when the car stops starting, the longest usage time is 60ah*0.5/15A=2 hours.
Of course, in order to protect the car battery to the greatest extent, the Erayak Power Inverter Boozer 2021 will automatically stop when the battery voltage is less than 10.5V.
