Review: So happy with this purchase that I came to purchase another one to keep in my daily vehicle!! Got tired of dragging out the jumper cables every time I needed to jump a vehicle or piece of equipment off. This box comes in a nice case, had a partial charge on it and used it on my diesel truck as soon as it arrived so i could move it to the shop to change my batteries. I charged it up and have used it a few times since then on tractors and other equipment that doesn't get ran daily. It is nice, great value, and convenient. As far as I can tell is going to jump several things before it needs another charge.
Review: Okay, so this product is amazing! I am beyond pleased with the performance, ease of use, battery life, and convenience it provides. I really should get a commission on sales for this product. For some reason cars tend to breakdown In front of my house and my neighbors have issues with their cars not starting. Several of them have similar battery starters but they never work for some reason. Then I show up with my trusty charger and I tell them, “Here, give this one a try.” For those who have their own devices they tell me it’s not working. I push a little and say, “No, just trust me…give this one a try.” Reluctantly, they acquiesce and give it a go. Less than a minute goes by and they turn the key. Varoom! The engine roars again and they thank me, take a picture of the device, and ask me where I bought it. Some buy the device right one the spot. In fact, my neighbor who needed a jump this cold wintry morning said she is buying one for herself. Don’t think about it or try to compare products. Put it in your cart now and press checkout! You will not be disappointed.
