I've been eyeing Antigravity's XP3 jump starter for some time. I like it cause it'll jump anything from my tw to a 5.7 v8 and my Ktm if needed. It's also so small it'll fit in your pocket or backpack. Seems like a great item to carry with you if you don't have a kickstarter. It's also a lot cheaper than installing a kickstart at $80 shipped. I know it'll jumpstart a car over and over, that's not in question, but I'm wondering what you guys think of this vs a kickstart? Good idea or?
