Years ago my car battery went dead in a parking deck. The attendant came along with a similar booster and started my car up easily. I got mine to jump start my vehicle and my garden tractors. Sometimes my battery runs low on my tractor and it occasionally needs a boost. If my battery on my tractor goes dead while working in the woods I can simply walk it over to it and jump start it instead of having to tow it out. It is easier than switching batteries in the woods also.
This does not come with a charging cable so you have to buy that separate. For the price, the charger should include a charging cable. Or at least it should be stated on the box that charging cable is not included.
It only worked once. Try using it again, won't happen. I wish to return
I am very happy with this charger for its functionality reliability
