Am thrilled !!! Super Service, all expired quickly and perfectly.

This product makes a really good impression, it is very finely processed. You can really forget the traditional jump start, which is large and heavy.
The instruction book is great! Simple and detail. The device is easy to use. Connect the cable to the terminals to the device, then the red clamp to the positive pole, the black terminal. To the negative terminal Done. Button on the Jump Start Device to ON. Start!
The intelligent cable is a highlight that can not offer any provider. So that I can prevent that I connect the wrong cable and pass interference. Who knows when I'm under stress, which may perhaps happen. Safe is always good!
With 400A starting current it is sufficient to start my car, I think it is also sufficient for normal passenger cars. Also, I'm very happy that I can use the jumper as Power Bank. I can just put it in my pocket and take it for hiking or camping. It has my iPhone fully charged 4 about 1 hour.
So overall I would give this product 5 stars, it is very recommendable!
