Slime Deluxe Digital Tire Inflator Air Pump 12 Volt - 40077

I really liked how it works perfectly. So simple to use, just hook up and let it work. The automatic shut-off at pressure feature, it is wonderful. The digital display could be larger, but it works fine, and it has a bright light on it. The cord is super long, I love it. I was impressed by how it was super easy. It is a lifesaver. I love it. I am glad I chose it. I recommend it to anyone who needs air in their tire, more than a few times in a day or week, because you are too lazy to go get it changed, like me. I eventually did get a new tire, but this baby works like a charm. I never leave home without HER!! How do I know SHE is a HER? Pressure Management: A tire inflator's primary job is to maintain the correct PSI for safety and efficiency. In a metaphorical sense, WOMEN are often looked to or sought out by MEN for "pressure relief" or for help maintaining balance when life's external pressures become too high or too low. That's how I know! YOU GO GIRL!!! Women RULE even in the MACHINE world!!! Happy hunting fellas!!

This is user friendly, compact (less than a shoe box) so easily fits in any trunk and pumps air quickly. Perfect for when tires lose pressure in changing weather. My sedan has 35psi tires and it was very easy. Does not use electric wall outlet. Powered by car outlet.
