A car battery jumper also called a jumper cable or a jump starter, is used to temporarily provide enough power to a dead car battery from a working battery in another vehicle. When connected to the jumper cables, the car with the dead battery can start its engine; essentially, it "jumps" the dead battery to provide enough power to crank it. Auto Max Tool provides a TOPDON car battery jumper, which provides power to a dead car battery. https://automaxtools.co.in/
