It's exactly what I needed. Perfect for any kdy unless maybe you trying to air up a monster truck tire lol. I have been caught before with a nail in my tire and no air compressor nearby. I have had something similar in the past that has saved me as in being able to air it up enough to get to where I need to be to fix it. Also those of you with spare tires. I doubt you have used that spare in awhile, it probably needs some air. I doubt you regularly air it up. So when you have one tire blow in the middle of no where if you have this device on your vehicle your spare will be in perfect shape to go.

My one and only complaint is I wish the bag it comes with to store in was just an inch bigger. It can store everything cleanly, but takes a second to put it on bag cause the bag just barely fits it but it fits it.

Arrives on time, product was neatly packaged & came with all advertised pieces. Works as advertised, isn't the quickest air pump by any means but does the job as a portable digital air pump. 4 star rating, it does vibrate around depending the surface it's sitting on while pressurising. Other then that no complaints, now the test of time.

I purchased this to leave in my trunk for emergencies and the first time I tried to use it, the power/flashlight comes on, I set the PSI I want and the compressor doesn't work at all. I tried switching power sources, verified my vehicle supplies the correct current, turned it on and off again, set the PSI higher than I needed and the compressor motor still never comes on. For a product rated so highly, I can't believe it didn't work even once. I ended up with less air in my tires after the bleed from attaching and detatching the valve. Would not recommend anyone buying this as you can't be sure you will get a working one.

I called EPAuto after my issue with the tire pump, but hung up shortly after not being able to reach their support. They called me back a few days later and after a quick discussion, offered to send a brand new unit for free. I didn't get a chance to test it until just recently to inflate my wife's spare tire in her trunk. The manufacturer recommendation for this spare is 60 PSI. It was doing a quick job at it up until around 45 PSI where it slowed down dramatically. It still got the job done eventually so I can't fault it on that.

Pro: This air compressor has one of the best cable management systems compared to those I have used in the past; there are notched to hold the air hose around the unit with additional slots to hold the 12V wire on the leg base. It also comes in zip up travel bag. Setting the desired tire pressure is also very quick as the numbers scroll very rapidly.

Con: Pumping slows down dramatically at higher PSI. The light on the unit also can't be turned off. Not too many negatives as long as this one keeps on working!

Great portable pump. Functionality is great and the cord is definitely long enough to reach all four wheels of the vehicle. The reason why it isn't a full 5 star rating is because the light switch it in a awkward placement and that there is no place to wrap the power cable to store nicely.

Briefly, it does what it needs to, and well. It cuts off automatically when reaching target pressure. The screw-on inflation nozzle is leak-free, at least to the 36 PSI as far as I tested it. Handy thing to have in your trunk. No regrets.
