I have not used it to jump a car yet, but it is nice to charge USB devices from it forever.
muy buena herramienta
It started my car
Battery died on me Thursday morning because I sat in my car and looked at my phone and didn’t realize the headlights were on. Car would not turn over. I hate hate hate jumping car battery’s with other cars. Decided to find a jump box and unbelievably I was able to order one Thursday afternoon and got it Thursday night! Right out of the box I was able to jumpstart my car. Ill be getting 2 more of these for our other cars.
