Great product!

This product is amazing and I love the battery life because I had jumpstarted my truck four times before it got to 50% so I would recommend this product to anybody that needs a small jump starter that starts up trucks! At first I thought I was going to get scammed because of the price but luckily I did buy this product because it's very convenient at times in need!

Both my husband and I keep one in our cars. My husband uses his to keep his phone charged when he is away from the truck and buildings.
