The ESA30 Memory Saver Connector turns any jump starter with a 12V outlet into a vehicle memory saver. The ESA30 creates an interface between the jump start and the vehicle's OBD II port, which is not disabled when the vehicle is turned off, making it an efficient means of turning a jump starter into a memory saver.
