AstroAI Air Compressor Portable Tire Inflator 12V Offroad Air Compressor for Truck 150PSI with Digital Display Dial 7.06CFM Air Pump for Car Heavy Duty for 4x4 Vehicle, RV, SUV, Car Accessories

The compressor shuts off automatically if the pressure in the hose gets above 160psi. There are many videos online of users upgrading similar compressors by adding such a pressure shutoff switch. I like that this compressor already has one built in. Ironically, I actually don't often utilize the automatic shutoff because of the 2nd great feature: the bypass valve built into the inflator gauge attachment. My process: 1. Attach the inflator gauge to the valve stem. 2. Fill the tire to an actively-inflating pressure (higher than actual static pressure) that I know from experience results in an actual static pressure roughly equal to my target pressure. 3. Open the bypass to shunt the airflow. (The pumped air flows out of the base of the inflator gauge attachment instead of into the tire.) 4. Read the actual static pressure shown on the inflator gauge. 5. If too low, close the bypass and inflate some more. 6. If too high, use the deflate button. 7. Detach the inflator gauge from the valve stem. 8. Move to next tire. Repeat. No need to run back and turn off the compressor to determine actual static pressure. No need to remove the inflator gauge and test actual static pressure with a second gauge. The compressor simply keeps running all the time, even while switching between tires. No need to stop and start the compressor. A third great feature is using the inflator gauge as a standalone deflator tool. I attach it to a valve stem, open the bypass valve to bulk-release air, close the bypass valve to check psi, then use the deflate button to fine tune the last bit of deflation down to my target pressure. All of the above is more efficient with a clip-on chuck. AstroAI should include a clip-on chuck in addition to the screw-on chuck.

This thing works so well and is made so solid that I am tempted to order another one just to have another experience as satisfying as this one was. I have used it multiple times on 100psi tires and the only warning I have is to keep an close eye on it. It is so much faster than anything I have used that I over inflated two of my rv tires. If you need something to rely on in the dark on the side of the road this is it. This kit has all of the gadgets and components that you could need for tire inflation. And all in a nice canvas case to keep it organized. My tires are 100 psi and it fills faster than most commercial air compressors. I highly recommend this unit if you need a mobile solution.

This thing pumps up my 33x11s from 18 psi to 36 psi in under 2 minutes. I love this compressor! Sturdy built. Gauge works great. Hose attachment gets warm after a couple tires but they all do that. Highly recommend!

This air pump is beast design good built with quality portability and the airflow is massive a 7.6 CFM. A nice thing is that it will fill your tires in Minutes and and you know it’s gonna last you a long time because the way it was built very powerful. A little heavy, but that’s to be expected with the way they designed it heavy duty probably will never need to buy another one in my lifetime.

I like that this compressor has plenty of power, it’s easy to use/put together and the hose is long enough to reach to the back of any normal sized vehicle. The battery clamps aren’t the most durable (the reason why I’m giving this 4 stars) but they are large enough to fit on larger battery post connectors. That being said…. I am a female and for this reason, I wouldn’t suggest purchasing this compressor unless you’re familiar with your vehicle’s battery location and, are familiar with how to connect/disconnect an air chuck. The directions are written for people who have a mechanical background, not for someone who has never put air in a tire. The suggestions read: Accuracy, Functionality, Weight, Design, and Heat level The Pressure gage reads accurately. It’s functional hence, it airs up tires. The design is compact, it weighs almost 20 lbs and it does heat up quickly so, be careful where you pick it up.
