He knows how to start a car with a dead battery. By itself, the capacity is not enough for an infinite number of times, but it should be enough for 4-5 launches in a row. For 1 start on a half-dead battery, 1 division of charge takes me. Overall, the device is light and compact. Doesn't take up much space on the shelf. Yes, it’s not worth keeping it in a car or a cold garage, in the cold the internal battery is also discharged and the meaning of the booster is lost.
