TIRE INFLATOR EXPERT
Digital Screen, Real-Time Pressure Display: The bike pump with large digital screen displays the tire’s real-time pressure for a more accurate and intuitive experience. Avoids pressure reading errors common with dial tire pumps.
Preset Tire Pressure & Auto Shutoff: This air compressor will automatically shut off once it reaches the preset value, no need to babysit the inflation process and worry about overinflation. To inflate: just start the engine, insert the cigarette lighter plug into the car’s 12 V outlet, connect the tire, and preset the desired pressure by pressing “+” and “-“.
Instant Inflation: For tires with the specification of 185/55 R14, this car tire pump can inflate from 30 PSI to 36 PSI ＜ 1 min, and can fully inflate a tire from 0 PSI to 36 PSI ＜ 5 mins.
Ultra-Long Power Cord & Emergency LED Light: With a 1.57ft long air hose and a 9.87ft long power cord, the car tire inflator is easily connected to any tire. The integrated LED light is great for emergencies and working in dark environments. When the digital tire inflator is powered, the LED light will illuminate.

Worth it for peace of mind to have in car
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 usingcar must be on to use

Excellent Value for Price
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.

TOO SOON TO TELL? NO – SEE UPDATE
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.

Great little air pump for the car! Easy to use and versatile!
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!!

Great true inflator
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.

Good inflator for awhile, then had toto get a plug in type
Works good and faster than the last one I had, but if you’re tire is completely flat, battery won’t last long enough to finish, half the time, not showing PSI on display…… UPDATE… this is the inflator I bought to replace the chargeable inflator

Attachments will be lost in no time
Right off the bat, i should have listened to previous reviews. Seems a decent little air compressor, but all the attachments will easily be lost the way they designed this. They would have had a better rating if only they would have put a little cover on the attachment space, without one all the little valves will be easily lost.It’s definitely easy to use and inflates quite nicely. The functionality and weight are both satisfactory

This AstroAI 12V tyre inflator is a solid performer. It inflates tyres noticeably faster than I expected I went from almost flat to full pressure in no time at all. Super easy to use: clear instructions are included, the hose and attachments are straightforward, and it connects nicely to the car’s 12V socket.Yes, it’s definitely on the loud side when running (like most portable compressors), but that’s completely expected for something pumping this much air so quickly. The noise isn’t a dealbreaker at all given how well it works.Build quality feels decent for the price, it’s compact enough to store in the boot. Highly recommend if you want something quick and dependable without fuss. Great value!

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!
