Nice portable jump box
I'll give it a five star jumped a dead cadillac DTS and a Cummins. Took forever ever to charge up when I opened it from the box. But it was at 80% after both jumps. So it earned it's place in my tool box

It just works!
It just works! You plug it in and a little green light confirms you don't have the cables backwards, then you start the car. It could not be easier to use. So much less hassle than dealing with jumper cables.

The ultimate "I don't need a man" starter pack
VERY user-friendly, a dumb blonde can look like a pro under the hood with this thing. It literally tells you if you are not hooked up correctly, and when you are, you get the green light to start your car. I feel this makes the product safe to use. It works for a V6-V8 engine; it says it works on a diesel, but I don't have one of those, so it's up to you guys to let us know. It looks heavy-duty and feels expensive. It also has a long-lasting battery life even after jump-starting a dead battery. I highly recommend this product. The only negative thing I can say about this product is that it didn't have a good storage case; it came with a sack, not the greatest.
