You Don’t Need It, Until ?

My wife’s always telling me you don’t need another gadget,but not this time. My daughters car was in the garage on a freezing day, and of course the battery died,and she-had to be somewhere. I didn’t think myG40 would be charged since I charged it like 8 montns before. I couldn’t believe it still had a lot of juice left,and started her car right up.She is going to college in the fall,so I will be buying another one for her. I looked at several portable jump starters,and found cheaper ones,but this one had the best reviews.Remember you get what you pay for.

Yes, I recommend this product.
