We all know that car batteries only die when you’re in a hurry to get somewhere. So rather than calling AAA or relying on a random passerby to give you a jump, pick up a self-contained jump starter for $40 or less.
If you own a small sedan, the $36 model from Suaoki should be fine, but most of you should just pay $4 extra for the 600A BESTEK, which is capable of jumping gas engines up to 5L.
