I work at a dealership that has like 3 JNC 660s. They’ve never let us down and I wanted to buy one myself. I bought the JNC 550A solely because I wanted the air pump feature. I jumped a Mercedes C300 that hasn’t ran all winter no problem. I just hooked it up and waited about 2 minutes. Boom. Cranks right up! I’m telling you, but a JNC and you won’t regret it.

For the low price, you can't get a more powerful jump starter for your car. Also there's a digital voltage readout, that also lets you know when it's battery is fully charged. And there's also a good quality tire air pump included.
