    I had no idea about the 600A starting current, and later I discovered that it is very little. I couldn't start two cars. 1400cc and 2000cc. It keeps flashing red and green, I press the force start button to see if it gives extra power but it doesn't work and the cable indicator turns permanently red. Additionally, it takes an excessively long time to inflate a car tire. For bicycle tires, balls, and charging mobile phones, it is okay
