DieHard Automatic 12 V 600 amps Battery Jump Starter

Excellent piece of equipment, both my kids and a nephew got one from me. Own one myself.

I have had this for about two years now, this summer I had to use it. I was so relieved, I was camping and left the key on, the cars interior fan was running on low, and I was distracted, and by the time I realized it, the car was pretty much dead. I later left the door adjar and the interior light on the door was illuminated and wore the battery down again, and I had to use it again, worked like a charm. Thank goodness I had this in my car. Hooked it up and it started right up, and only used a little bit of the power it had stored, so little that I did not feel I needed to charge it right away. I checked it a few months later, still showed like 83% left, I still have not recharged it, however it is getting cold in Michigan, so I probably should top it off because it is much colder conditions it is stored in, and probably will lose its charge faster because of the temps. I totally recommend it. I was surprised to see someone gave this a one star rating, and said they would not purchase or recommend "Schumacher products" in the future, I am not sure why they referred to this "Red Fuel - Die Hard Battery Jumps Starter" as a schumacher product, perhaps they placed their review on the wrong product. After reading that, I had to offer my experience with this product, and I have recommended this product to friends and family. It saved my butt!
