AstroAI Air Compressor Tire Inflator Portable Air Pump for Car Tires, 12V DC Integrated Metal Structure Tire Pump 160PSI with LED Light for Cars, Bicycles, Motorcycles, and Other Inflatables(Blue)

This little air compressor actually managed to exceed my expectations. I was not expecting to be able to air up my tire - from flat - 3 days in a row. I noticed I had a slow leak in my tire, and of the many tools and gadgets I own, a portable air compressor was not among them. I live in a rural area, plus general life-getting-in-the-way stuff prevented me from getting an immediate fix. Amazon to the rescue. The compressor itself is very lightweight and has convenient storage solutions for the main hose and the power cable. The display is simple and easy to understand once you have read the instructions, and the included (albiet tiny) switch-operated spotlight is adequate. The pressure hose seems sturdy and solid enough, though I am no judge of automotive gear. DC outlet required, which I plugged in after I started up my car. Set this guy to 35lbs, plugged it in, popped the compressor hose head on the tire gasket, and locked it in place. Flipped a switch and let nature take it's course. It took my tire from flat (car said 8lbs) to 35 lbs in under 5 minutes, which I find acceptable for a unit this tiny. Like, it's much smaller than it seems in the pictures. Had to do this twice more for the following 2 days when I finally managed to bring 'er in for new tires. This little compressor performed exactly the same way every time, and although it did get a little warm, it seemed to do it's job well. I'm gonna keep this in my SUV.

I finally had a reason to use this portable air compressor when I discovered a slow leak in a rear tire and needed to bring it from 7 psi up to 37 psi. I really appreciated the digital pressure readout as soon as I connected it, and being able to watch the pressure climb in real time while it inflated. That is much better than constantly switching between the compressor and a separate air gauge. It did take a few minutes to add about 30 psi, but that feels perfectly reasonable for a compact, portable unit. The best part was doing it in the comfort of my garage instead of squatting at a gas station in 2 degree weather. It was also very straightforward to plug in and run, and I feel confident I could use it while parked at a rest area, or even on the shoulder of the road if I ever had to. Overall, it is an easy, practical tool to keep in the car for peace of mind.

Works great! I’m sure it will come in handy again. Found myself in 0° temps with all the gas station pumps malfunctioning and shops closed and this shipped next day. Took 10 mins to fill all 4 tires from ~26psi to 36psi and the cord was plenty long enough for my sedan with extra if needed for a larger car. Auto shut off worked. Will definitely keep for winter and road trips.

We bought this because there are fewer and fewer places around here for tire inflation air. It works fine. It plugs into a car's 12V outlet, and the cord is long enough to reach from the dashboard to all four tires and the trunk if there's no rear outlet. When you hook it up to a tire, it shows the current pressure. Then you can set the pressure you want and turn it on. It fills the tire and stops at your set pressure automatically. It easily handles a 60 PSI "donut" spare. It has a small light if it's needed at night. I knocked off a star because it's very loud and vibrates to the point of "walking" around, and the compartment for cord storage is too small. This doesn't affect its function, though.

I bought this compressor just to have in the truck for any tire issues. I tested it and it does work as described. The pressure calibration is on the dime. I filled one tire from 35psi to 40psi according to the compressor readout. When I validated the pressure with my accurate pressure gauge they both read 45psi. It did fill the tire at a normal rate for a portable air compressor. It's not extremely loud, and while it is all plastic it looks solid. Hopefully it will last for years to come.

This is a wonderful and powerful little compressor! Slides on and off of the valve stems effortlessly and the light is very handy when using in dimly lit areas. The cord is long enough to reach front and back tires on my Honda Civic. The auto shut off is wonderful and this is SO easy to use. The attachments have their own storage nooks so they are readily available. Very much a value and gives peace of mind while out and about since it is not easy to find places where you can get air for your tires..at least not where I live. Highly recommend this!

Updated post. Received feedback a timely reply from site support. They ask me to try running the pump disconnected from the valve. I did this on 10/19/2024 and the pump worked as it was designed. I reduced the tire pressure on 4 wheels and set the pump to 35 lbs. It pumped each tire up the selected pressure and then used a separate tire gage to confirm the tires were at 35 lbs. The unit worked properly so will keep this pump handy for future use. Support was very polite and offered to refund or replace the unit I originally received but have decided to keep it and update my review from 2 stars to 5 stars. Original post 10/15/24 Question for other owners. Mixed review on day 1 in using this product. I did read the entire English manual. This involves car 1, car 2 and an emergency spare tire. Car 1 topped off 4 tires ranging from 31 to 33.5 lbs to 36 pounds, and unit worked without issue. This took less than 5 minutes. All four tires received 36 lbs and unit stopped at 36 lbs. Went to car number 2 and tires needed to be at 35 lbs. Topped off tires ranging from 31 to 34 and first tire was pumped to 35, next 3 tires the pump stopped at 34.5 lbs. It would not pump the last 3 tires to 35 lbs, which is what it was set at. Then the emergency spare was to be ad 60 lbs and it originally showed it had 40 lbs. I adjusted the pump to go to 60 lbs and it would not go above 34.5 lbs. I know I changed the setting to go to 60 but I needed a bicycle pump to get it to 60 lbs. All of this activity took less than 15 minutes. The unit was just slightly warm, not at all hot. Has this happened to any of you? If not, I think I will need to return it.

This is really good, bought it because the inflator at the local garage is always out of order. So we thought we’d give this a go. Very impressed, the tyre was down to 7.5 psi, and needed to be 33 psi. It too the unit about three or four minutes to re inflate to correct pressure, at which point it automatically turns itself off. 5 Stars all day long. Obviously, we will have to see how it does in the long term, but it’s not like your using it everyday, so, so far very happy.

Does not allow tires to be inflated to 35 PSI

Lastikçiler de hem fikir olacaktır. Araba lastik basıncı benzincilerde ayarlanmaz. Bu yüzden çok iyi oldu. Yolda kalsanız dahi en azından acil durumda şişirerek lastikçiye kadar sizi götürür. Daimi olarak bagajda duruyor.

Après plusieurs utilisations, le compresseur fonctionne très bien. Facile d'utilisation ( arrêt automatique sur atteinte pression demandée), complet avec plusieurs embouts et 1 fusible d'avance. SAV réactif (contacté car j'avais cru que le compresseur était HS mais en fait je n'avais pas enfoncé assez fortement la prise dans l'allume cigare, c'est le seul bémol). Après plusieurs mois d'utilisation je recommande l'article
