This worked like a charm in a pinch. I have a 2004 Isuzu NQR 6.6L Diesel truck. It dies sometimes when I stop and start too often or use the lift gate too much without running the engine. It died yesterday in the middle of a job and this jumper box worked first try. I felt confident that I could turn off the truck between stops and jump it again and again. I jumped it 3 times and still had half a charge. This was a life saver. I prefer a more powerful unit with a bigger batter so I am not sure if this was the smallest model I needed for the job but I like to be prepared. Would highly recommend everyone have something like this in their car and in case the power goes out at home to charge devices from.
