CAR BATTERY CHARGERS VS. JUMP STARTERS
A car battery charger is a device that is used to charge or recharge a car battery. They can provide a consistent flow of power for recharging or maintaining the charge of a vehicle’s battery when discharged or fully charged. Generally, car batteries require a 12-volt DC type current to charge. But the electrical outlets put out 120-vol AC type current which is not suitable to charge the car battery. Battery chargers convert this 120-volt AC drawn from an electrical outlet to a 12-volt DC outlet to make it suitable for charging the battery. Since they don’t have dedicated charging ports, they come with special cables that connect to the battery terminals.
Now, if we consider a jump starter, it is a portable battery pack designed to jump-start a car when the battery is dead. It can jump-start the car battery without the help of another car or source of power. This comes with specialized jumper cables that can draw power directly from the jump starter’s battery when the cables are connected to a dead battery. It actually provides a kick to start the battery without providing it any charge through a quick burst of power. These devices are not able to charge a battery.
