Over the course of four long days, in addition to jump starting that JK twice, we were able to recharge Trasborg’s Samsung S4 Active from 5-percent battery to 100-percent while streaming Pandora over Bluetooth to a mobile boombox at camp while grilling. We recharged an iPhone 4S from half power to full, and we were able to extend the life of this laptop. Normally this laptop lasts for only 11⁄2 hours on battery power while watching movies or surfing the web. On the Micro-Start we were able to use it for almost six hours. After all of that, the Micro-Start was still showing three bars of battery power left. I would have liked to kept jump-starting Jeeps but I couldn’t find any more dead ones.
