— devices designed to start the engine in cases where the standard battery cannot spin the starter (for example, if the battery is discharged in the cold). Jump starters can come in handy in situations where the engine needs to be started urgently and battery charging is not an option. At the same time, such models usually have their own built-in batteries or supercapacitors and can even be used "in the field", regardless of networks. However, there are also units connected to a power outlet — they can come in handy, for example, in a garage.
