It charges back once a person charges a car, has ports on it to plug devices onto, has flash light, and is super durable. Ive even used it to hold hoods up to junk cars that have no pole. Ive used these things for years and they have the best power. Definitely a great purchase. Have also helped plenty of people save a few bucks from dead car batteries just at random places.
