The Micro-Start has a 200-amp starting current rating and a 400-amp peak current rating. I’m used to four-number amperage ratings so I didn’t think it was going to be enough. The first test of the Micro-Start was early one morning. Everyone in camp left, the Jeep was dead, there was no cell signal, and our only hope was this little black box. Nothing like a trial by fire, but you’d probably be this happy after it worked and the Jeep started. Trasborg actually did the happy dance that first morning. We played around with the flashlight a bit that night. The next morning, was the same story with no happy dance. It jumped the dead JK again and the power indicator was between four and five bars (full) of power.
