every owner that has a vehicle should keep one in their vehicle. Simply use, powerful and compact.

Works Great, so much easier to charge, store and rely on than the Stanley FatMax that was always temperamental to get to work. Would buy again.

Great product for the price! Compact with good quality. Came with 75% charged so it worked immediately after it arrived.

Smaller than I expected but works well. Started a Subaru Outback with a completely dead battery. But its internal battery power went from 100% to 40% During the starting process, so the advice in the user manual to make sure it is fully charged before trying to start a car with a dead battery is best heeded. I did note that when I went to recharge it after the dead battery start, it had rebounded to 85%. If you have USB charger that can provide 9 volts 2 amps, it recharges pretty quickly. If you only can provide 5V, it will take quite a while to recharge. Overall, I am quite pleased. It is compact and easy to use, and it works!

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.

I used it to jump my car (sedan) this morning and it worked like a charm. As a matter of fact, I used another card and traditional cables and my car wouldn't turn over. Once I strapped this on, it worked perfect. I am recharging it now and it does take a while, but if you let it recharge over night, I bet it would be fine. Instructions could be a bit more clear but fairly understandable. The cable length shouldn't be an issue, but I can make an argument for them to be longer. The best thing about it is the carrying case that comes with the cords and how fast it worked to make my car start.

Works well and battery remains charged for several months. Used it once after not being charged for 4 months on a 4 cylinder diesel. Started right up and only used 40% battery. Small size that fits well in a glove box.

What a blessing and magnificent product, people! I have used this more to help others than myself. I keep it under my front seat. It stays charged as long as not used, is a high quality product, so not cheap and the case that is comes in, is also awesome. The price is way too low for how much it has helped me. The cool thing? About 2 minutes to take out of the case, connect to the battery and start. Storage right under my driver's seat. Instructions, cables all included. Love it, love it, love it! (Now if it could just pay my electric bill!)
