How do mechanics start a vehicle with a dead battery?
Answer Jump starter
A jump starter, which is also known as a power bank, is basically a large battery that's used to start a car with a nonfunctional power supply. Vehicle owners can buy consumer-grade versions of this tool to keep in the trunk in the event of a breakdown.
