AstroAI Air Compressor Tire Inflator Portable Air Pump for Car Tires 12V DC Auto Tire Pump with Digital Pressure Gauge, 100PSI with Emergency LED Light for Car, Bicycle, Balloons and Other Inflatables

Excellent priduct! I admit that i do not know that much about a car and so i have been to auto shops to ask them to give me some air in my tires whenever i felt that the tire pressure was low. Now, i have a 2022 sedan. Somehow the tire pressure monitor has come on more often that i anticipate. So, i went to the autoshops to ask them to give air to my tires. However, after covid, it seems like they are of short staff and do not have time to help me. I understand. So, i have to help myself {i dont know how to use the air pump at the gas station}. I started looking at amazon and came across the product-easy to use, portable and not expensive.
Today, i use this compressor for the first time. This product meets the specifications- easy to use, fill up air at preset psi at reasonable timeframe, shut off by itself when it reaches the preset psi, lcd digital display
clear to read. I check the autoapp and it works. I will see the milelage this air fill gives me. I gave 4 star for accuracy due to the fact that i set psi at 32 and the app reads 31.no big deal. I see this difference even i go to an autoshop. I would say the pump is accurate. 5 stars on accuracy will be fine with me. I am glad i found this product.

Note: i have only used this product once, so this review is not about its long-term reliability. One of the biggest issues with cheap consumer goods is not that they don’t work at all; it’s that they break down after only a few uses. I’ll come back and edit this review if the device fails after subsequent uses.

But…

If it doesn’t break after a few uses, this will probably be the best 30 bucks i’ve ever spent on my car. The last straw was yesterday, when i tried to fill the tires at my local gas station, and the battered nozzle just wouldn’t sit flush on the valve stems, causing me to lose more air than i put in. After a lot of swearing, i drove back home on my under-inflated tires (luckily it’s only a mile) and ordered this device.

It arrived today, and within 20 minutes of delivery all four of my tires were back up to 36 psi. It’s incredibly easy to use, it inflates the tires pretty quickly (19 psi to 36 psi in about 3-4 minutes), and the gauge (on my unit, at least), seems reasonably accurate. After comparing its readings with the good analog gauge i keep in the car, the compressor’s gauge reads about 1 – 1.5 psi low.

I was also pleasantly surprised at how small and light it is. It takes up almost no room in the trunk.

As i said, time will tell if it actually keeps working, but so far i’m very happy with it.

Received this item yesterday; first use today. I drive a late-model full-size suv, and it has big tires. Door sticker calls for 35psi. I like to over-inflate just a bit to 37psi, so if the temperature goes down it’ll still be okay. Between tire rotations the pressures drift, probably due to valve core leaks, and recently the four tires varied by 8psi, as low as 9 below the setpoint.

The station where i get my gas has a ‘free air’ machine that is almost always out of order. The nearest tire store is clear across town. I felt a need to have a small inflator for intermittent use, and chose this one.

I found it simple to use, easy to set up, and apparently well made. Comes from china, but has a solid, quality feel to it. The automatic shutoff is a welcome feature. The power plug makes perfect contact, and i was able to reach all four corners without having to re-connect. But what really impressed me was the consistency and accuracy. After making the rounds and inflating all four tires, i ran the car’s on-board diagnostics, to find that all matched and were spot-on the setpoint! This was confirmed by my analog gage. I couldn’t be more pleased with this little beggar!

Pros: light weight, reasonably quiet, punch in the preset pressure and turn the switch ‘on’, inflated my suspension air bags from 0 to 30 psi in 10 – 20 seconds. Cons: the power cord is 3 meters long which wouldn’t reach my suspension airbag valves by the rear license plate (although it would reach all four tires on my pickup from the rear piwer socket), response to the preset values overshot precise values (30 psi setpoint vs 32 psi finish – the air bag volumes are small relative to pump capacity, so i anticipate more accurate finish pressure on something the size of a car tire).

Summary: i had a plug, socket and wire to easily make an extension cord; an extension cord is readily purchase-able via amazon but i was leaving on a trip the next morning. Overall, i’m satisfied with the performance and value.

I have a small leak in a tire, small enough that the tire is able to hold pressure to drive on, but big enough that i want to get it repaired asap. Having realized this on a friday afternoon, i ordered this unit right away. It came on sunday, and true to form, it pumped the tire up. The only confusing thing is it came with an extension and many other nozzles that i thought i should use, but straight screwed into the port was the best connection. Once connected and turned on, the guy pumped it up steadily up to my set pressure of 32 psi. It took 3-5 minutes, and…that was it? The thing was $27, way less than the price of any tow you’d ever need, and way more convenient than having someone come out to fix it. As is, i should be able to make class monday morning, pump it up afterwards, and then drive it straight to my repair shop to have the tire properly fixed. This will ride along with my portable jump battery from now on, giving yet another layer of self sufficiency out on the road.

I am so glad i purchased this 2 years ago. It has served me well and is still going strong. I have used it on 5 vehicles and 2 riding tractors at least once a month as general maintenance, yet it has never failed and is always accurate. I haven’t used it to completely inflate a tire but have had to put in up to 8 pounds and it performs this pretty quickly and with minimal noise considering its size. It is light and easy to use with plenty of cordage that stows away nicely in the unit. The light is bright enough to warn others of your presence if caught on the side of the road or if you need light to inflate a spare to get rolling again. I keep it all in the original box as i found it easier to keep track of all the additional attachments included but mainly use the quick release nozzle. Whenever my unit does fail i will definitely be looking for this again

I was a bit nervous buying this being that it’s so small but this air compressor actually surprised me with how well it worked! The price in my opinion was reasonable and the power this compressor has is pretty damn good. I used it to pump my paddle board, my motorcycle tires, my car tire, a basketball and my kids inflatable ball pit. I put it thru several differing inflatable scenarios and it worked perfectly. Came with several attachments to fit different valves and each one fit and worked. And yes you are able to program the psi to the desired air pressure. You can even change the desired unit of pressure. It’s compact so it doesn’t take much room in the trunk of my car which is where it stays in the invent i get a flat tire or happen to need it for something else. Go ahead and take a chance with this air compressor to see for yourself.

This item is ‘amazon’s choice’ for good reason(s). It is easy to use. I set it up for the correct pressure for my vehicle and it shuts off automatically at that pressure. It fills my tires up with air quickly. The pressure gauge is accurate and consistent. The cord is long enough to reach my vehicles 4 tires. Plus, it is fairly small in size so it fits easily in my vehicle. I am happy with this product. The only item i can see to improve this item is a more convenient way to store the cords. But that is a very minor thing. It deserves a 5 star rating.

The little thing is so amazing, i used to go to wawa and get air every other day due to a bad tire that i cannot afford to replace at the moment. Received item yesterday first use was today before heading out to work and it worked like a charm. I must say compressor is much smaller than i anticipated however it still gets the job done. This will never leave my vehicle as i feel it is 100% essential. I also love the fact that it automatically shuts off when it gets to the psi you send it to and i believe there was a small attachment that you can connect to inflate bicycle tires.

I really like this product it’s easy to use i keep it my trunk in case of emergencies. It has come in handy for me a few times i got 2 for me and my fiancé a blue and red. Fiancé and i went out of town with my family on our way home mg fiancé and i was following my mom back to home and her tire light came on luckily we had this in the car and was able to air up her tire and get going again. All you do is plug it into your cigarette port and set the air pressure on the machine and attach it to the tire, turn it on and wait for it to turn off. This product does get hot so i recommend maybe leaving it out for a bit to cool down before returning it to the box and package. I’ve read other reviews that it’s not always accurate i’m not entirely sure it is or not i haven’t tested it out myself. All i know is when my tire sensor goes on and i use this product to my tire setting the light goes off. My mom took her car in when we came back into a town a few days later and they tested her tires they did say it was off by a little but it was a very minimal amount.

For me this unit worked out very well for topping off my trailer tires and vehicle tires as sometimes they have the normal rim leaks as a lot of them do. It is a smaller capacity and does take a little longer but that is normal for this size of a compressor. So far i have topped off three trailers which would be 10 tires and one truck tire and all work fine with no overheating or blowing a fuse. Six trailer tires were topped off at 80 psi and four trailer tires topped off at 70 psi. Tire gauge on unit shows a consistent one and a half pounds over actual psi which is no problem at all and compensates for the little loss of air when removing the valve. A little longer power cord may be 5 ft longer would be beneficial but i can also use it off my heavy duty jump start pack for more of a portable use. Do not expect a high quality valve connector but it does work sufficiently. For the price and quality of this unit and what it is intended for i would recommend it for intermittent use. I will do an update in 6 months and 12 months. Thank you

I didn’t have great expectations for this product as it’s clear it didn’t work for some people. However, for me, it worked exactly as advertised. I was blowing up car tires which needed an additional 4 or 5 pounds. I set the pressure i wanted and it let it run. When it got to that pressure, it stopped. I checked with a conventional gauge (still a bit skeptical) and the pressure was spot on. I also used it to pump up my bicycle tires from flat and it did that perfectly as well.

So let’s get real. This is a small pump and the volume it puts out is small, so if you are blowing up truck tires from flat, it may take all day or it may overheat and cut out. I can imagine if you are trying to pump up large tires to 80 psi or something, it might never work. But for everyday use – like pumping up your car tires when the warning light comes on, or pumping up a football and probably even an airbed, it works just fine.

I recently purchased this product as a replacement to a similar portable inflator i used until the air hose sprang a leak (probably because it was continuously kinked when stored in the inflator’s storage compartment).

This inflator, like the previous one i had operates in the same manner. I tried it out this week on my car’s spare tire and 3 of the main tires. The cord from the 12v outlet is long enough to reach all four tires. Setting the desired tire pressure is simple. The light is a plus at night. The inflator is small and light which is good. I gave this product four stars only because the air hose should have been placed in the opposite direction to extend its reach a bit more. The air hose is similar to my other inflator, so i recommend not tying it up because it may kink. When not in use, i put it on a shelf in a closet and let the air hose lay as it may.

I finally heard from the manufacturer and they very kindly suggested some trouble shooting. It turns out that the device works fine, but one of the connectors was defective, which will be replaced. I am impressed by the responsive and kind notes from their support staff. If anyone has an issue with this product, my recommendation is to open a case on the company’s website, something i should have done initially.

It worked the first time, but the second time it wouldn’t inflate my tires. I sent an email to company twice; no response. And live chat isn’t working, even though i tried it during active hours. I seem to have completely lost my money buying this lemon. Very rarely have had problems with amazon purchases, and this is the first time i have gotten no satisfaction from either amazon or the manufacturer.

I have used this to fill my truck, my bicycle and the work truck and for such a small item it does the job. It’s not special but if you want something that as long as you keep it in good shape to last a while and keep your tires filled, this is a good option. Though one critique i wish the length of the cord and everything was a bit longer… It gets to all of the tires but having some extra cord doesn’t hurt.

My car tires were somehow all at 26-29lbs so while freaking out i decided to order this and see if i could pump them up at home without having to worry about driving on a highway to search for a place to put air in them.

Surprisingly this little machine worked very well! It filled up all 4 of my tires in less than 10 minutes. It did get a little warm towards the 10 minute mark but is wasn’t hot enough to worry about.

I loved that the nozzle that you use to hook up to your tire stem has a closing mechanism so when i took it off it didn’t leak any air like i’ve experience with other pumps. When i got in my car my tires were inflated to an exact 35lbs just like the machine displayed so i’d say it was right on the money and accurate. I’m going to keep it in my trunk for any emergencies.

Turned off when got to set psi, but did blow the fuse on my truck. Switch to other outlet and it worked for all 4 tires. Did not take long even going from 22 to 35 psi. Only used once to hopefully it holds up

Bought this as a replacement for another tire inflator machine i’d had for a few years. This one is a little different but still does the job for sure. No major complaints, just an adjustment so far. Tried it today and it worked fine for me. Should be fine for me as long as it lasts a while!

Gets the job done. However, i wouldn’t inflate all four tires from 0 because it’ll overheat. With smaller usage it’ll work every time.

Product works well and is very easy to use but it didn’t come with an extra fuse as advertised.
