Imagine the look on the face when someone approaches you to help jump start their car, only for you to roll up by the side, and hand over a Vantrue box, out of the window, without stepping out of your car? The look on that face when they return that box with some gleeful appreciation for the hustle-free process! These power boxes are simplifying life, Chinese made and all. What remains is how to store them safely inside the car without requiring the jump-starter-newfound-friend, some 50 miles prior, to rescue you with their old-school Kidde fire extinguisher (made in USA) from that very Vantrue.

Having one of these or one of the ones that is a jump start / tire compressor combo unit is a great thing to have in your vehicle for emergencies.

I have a similar product and it's a must. Sometimes there's nobody around or they can't get to you, not even AAA. I think mine has a lifespan of ~80 jumps. Guess how long before I'll need to buy a new one? Probably never...unless I go around jump-starting other people's cars.
