The battery ran out overnight. When connected, the green light blinked as a sign of too low voltage. In boost mode, the car came to life, but could not start. Started up only by lighting from another car with a pre-charge for about 5 minutes. This device apparently helps only with a small discharge. With a deep discharge is useless.
Included some photos to show the product's packaging and presentation.
