Clear some space in your trunk for this emergency jumpstarter. The Cobra JumPack is a compact rechargeable battery that carries enough juice to jump your car twice. It's reliable, efficient, and also has a USB output, so you can use it to bring a dead phone back to life when the power goes out at home. [$130; cobra.com]
