Review snippets: absolutely first class product. My car had been dead for 4 days. The neighbour was going to lend me his jumper kit but he didn't come round, so I bit the bullet and bought this. I bought the wrong one / This is a great device. I purchased two for my vehicles. It will start old diesels or new gas engines. Has great power. Highly recommend for a quick jump source while taking up only a small amount of room Great
