I have used this air compressor numerous times and I really like it. It’ll fill a totally flat 16″ tire in minutes. Yes, you need to open the hood and connect the compressor cables to the battery.
But that’s why this compressor puts out the power; you just can’t get a strong enough amperage through a cigarette lighter.

I carry this Viair compressor with me all the time. I like it for its air output, its duty cycle, its long power cables and long air hose, and its decent price.

Over the winter I found that the power cable cord became brittle where it enters the compressor. This exposed some wiring, which in turn blew the fuse. I just opened up the compressor by removing a few screws, taped the open wiring, and then closed the unit back together.
Took me around 5 minutes is all.

For the brittleness of the power cable in extreme cold, I’d drop this item down a star. But for its usefulness, the power it has, and the low cost, I’d give it a 5 star rating. All in all I would buy this item again.
