Was looking at that one, as well as the Micro Start XP-10. I've read good reviews about both. I use one daily at work and am tired of lugging around a large jump pack. However, I've heard the anti-gravity batteries don't perform well in cold weather. Being in California, you don't have to worry about that as much. I don't know how it would perform for me on sub-zero days. Let us know what you think of it once you have a chance to try it out.
