Review title: "Buyer beware - very disappointed in this product.
Product review: If you are looking for a power supply for portable items this is a good product. NOT so great for charging your car battery so dont buy it for that reason. I have had several instances where I needed a jump and had to take the charger in the house and charge it up forever. I have left it charging overnight in advance just incase, but that doesnt seem to help it store power. 400 amps just is not enough. There is no reason why this product shouldnt work for my car. I have a 2004 Corolla. Last night I was stranded again because my battery power was low. I had to call AAA. When the guy got to my car he told me my portable charger was a piece of junk. I agreed and will buy a diff one. Preferabley something with 900+ amps. But it charged up my cellphone pretty fast so that I could call AAA. I decided to just buy another one. I'm disappointed in this product.
