AstroAI S1 Tire Inflator Portable Air Compressor 12V DC, Digital Car Tire Pump 150 PSI, Preset Tire Pressure & Auto Shutoff, Electric Air Pump for Car Tires, Motorcycles, Bicycles, Other Inflatables

Great tire inflator also own a jumper pack in this brand, easy to use and great function to set the disired psi and auto shut off.

Works as described. Have used twice now. Takes a few minutes but will put air in tire. The cord is long enough to reach every tire. Certainly loud when using car must be on to use

First of all, don't "over expect" for $23. I bought this replacing a 20 year old unit for which I probably paid $40. The Astro is not as heavy but seems decently made. I definitely like the features of a built in tire pressure gauge and automatic shutoff. The length of the cords is ample and unlike a couple of other reviewers I had no problems I experienced no problems attaching and detaching the unit to my tires. My only "possible" issue is with the tire gauge. It reads higher than my pocket gauge. For instance, my pocket gauge read a tire's pressure as 30 psi. I set the Astro to 33 and it didn't turn on because it was reading the tire's pressure as 33 psi. So it comes down to which gauge is correct. I plan to borrow a friend's gauge soon and test that against mine and the Astro. I will update this review afterwards. Even if the Astro is off, I can adjust accordingly. It is certainly well worth $23. ***UPDATE - 1 MONTH LATER*** I checked the unit's pressure reading against two pressure gauges. It confirmed that the unit was reading a pressure 3 lbs. higher than actual. Is this a deal breaker - no! The unit operates well and for the price I am totally satisfied with it. If I want to inflate a tire to 33 lbs. I just set the unit to 36 lbs. It inflates and then shuts off - every one/every thing is happy.

I highly recommend one of these in your vehicle for emergencies. Don't fall for those handheld cordless ones you see on social media. Those will only inflate 1-2 tires before depleting. You have unlimited power for the plugins and it will inflate at least 4x faster. The AstroAI is compact, lightweight and powerful for its price. Everything folds into its rectangular form factor for easy storage. The UI is simple and to the point. You can easily set the target pressure and it will auto stop. It's also a nice looking design with black and yellow which are common colors for power tools and emergency equipment. If I were being picky, the 2 minor cons that you'll find in other brands are: no option to plug into wall outlet & doesn't come with a case or bag.

This is a great little product! You set the psi limit for your object and it stops as soon as it is reached! No guessing about it. I have it in my care for emergencies but so far it has been useful for pumping up the grandkids tires, balls, floats, etc! It has several adapters for different things! Easy to use and fast!!

Works great, fills the tire extremely fast.

Simple to use and it works. The cord plugs into the old cigarette lighter socket, which makes it easy to use and provides ample power. Bringing four tires up to 30 psi was a snap.

Works well. Wish the power cord was longer, if you have a pickup this could be an issue. But does what it advertises.

This tire inflator works perfectly and is very easy to use. It inflates tires quickly and accurately, and the digital pressure gauge is clear and precise. I really like the preset pressure feature — just set it and it automatically stops when the desired PSI is reached. It’s compact, well-built, and convenient to keep in the car for emergencies. Great performance and excellent value for the price. Highly recommended!

Absolutely fabulous. I'm not normally impressed, but I am with my purchase. I was completely stuck. I live in the middle of nowhere. I bought some posh valve covers ( what a joke). The next morning my tyre was completely flat, no air in it at all. I ordered the inflator, which came the same day ( thank you Amazon). I followed the easy to use instructions and WOW, the tyre was fully inflated in 5 minutes. You could have knocked me down with a feather. The best purchase I've made in years.

Good compact size and build quality. Pretty good speed of inflation as well.

Nice
