AstroAI Tire Inflator Air Compressor Cordless Car Tire Pump with 20V Rechargeable Li-ion Battery 150 PSI Portable Handheld Air Pump with 12 V Car Power Adapter for Cars Motorcycles LS40791（C1）

I love having this in my car so that I know that i will be able to air up my tire. The battery doesnt last the longest, but it does come with a cigarette lighter adapter as well so that you can use your energy port in your car. I love that you can set your tire pressure in the machine and it will stop once it has filled up to that point.

Small, portable and so handy! Really like the idea of being able to inflate my tire if it is low without worring about getting my car to an air pump. This pump isnt heavy, its very easy to use, easy to attach and lets you set your pressure with auto shut off. It came in handy when my tire was low due to a nail and my husband was working, I was able to easily fill up my tire and take it to get plugged. It saved so much time, glad I had it.

I got in my truck yesterday to pick up a take-out sandwich and go visit a friend. My indicator panel told me I had a low air tire. I realized it was time to test my new tire inflator. I chose to use the car adapter because I felt the battery would probably work, but I suspected more than one tire was low, and this is a full-sized pickup truck, not a little car so there’s a fair amount of weight on those tires. I will test the battery option sometime when I am not so hungry, perhaps on my air mattress. So, the cord reached just far enough…barely. I do wish the cord were just a foot longer for the adapter. That, however is my ONLY complaint. With the truck running, I got plenty of power to add 10 pounds to one tire, 3 to another, and the front tire needed 7. The truck’s digital panel tells me how much it reads in each tire, and when I was finished with all 4 tires, the numbers were perfect. The digital readout on the machine doesn’t work perfectly as I pumped, but it’s good enough. The actual tire pressures were where they were supposed to be when I was done. Doing all 4 tires only took maybe 15 to 20 minutes which I considered to be amazing. It wasn’t a fast fill up, but it was efficient and did the job right there in my driveway. I told my friend about it and now he wants one for his truck. This little compressor worked like a charm and could definitely get me out of trouble out on the highway someday. I’m so happy I have it. What a great tool. The photos in the description are accurate and show the product very well. This is something almost everyone should have in their vehicle, but especially those of us with older trucks that are getting the leaky rim syndrome. It was super easy to use…actually easier than the gas station air pumps for me. This woman calls this an excellent product.

This offers a piece of mind. Charger included for on the road power at any time. Additional pieces included for the type of tire filling. Recently had a slow leaking tire and this offers a peace of mind to be able to help myself in such a circumstance

I received this portable tire inflator free for review and Im super impressed. I finally got a chance to use this the other day in a real setting. Ive had a number of tire inflators over the years but never one that was cordless and not one in this form factor, their ususlly some large box type thing. So I was really curious to find out how well this would work, particularly in cordless mode. And you know what? It worked perfectly! I have no idea how long the battery will last of course, but it had plenty of charge to get a tire from about 15lbs to 30lbs in what I would say is the same amount of time as any other inflator, but without the cord! Anyhoo, Im thrilled it worked so well, its super handy to have it cordless for all kinds of things. The only I would change about it is the battery, I wish it was universal with another brand or you could buy more of them separately. Otherwise I highly recommend this one!

This review is for: AstroAI Tire Inflator Air Compressor Cordless Car Tire Pump with 20V Rechargeable... Pros: 1) Overall, well-designed and works well. 2) Convenient feature that allows you to set the needed pressure. Inflator shuts off when that pressure is reached. Cons: 1) Appears to have a proprietary battery. Currently, one does not need a battery while its new, but one could in the future. Not sure that a replacement is available. Not having a replacement battery if needed, could render the inflator unusable. 2) A bit on the large side compared to other inflators. May be difficult for some to hold easily, but his is NOT a dealbreaker. I will update this review if needed based on positive or negative experience(s) after further use of this product.

I got this tire inflator because I live in an urban environment where there are fewer and fewer gas stations nearby -- and even fewer still that have functioning tire-inflation stations. Or you need about a dozen quarters to use a pump for one minute, and then it stops. But I also figured I might need to use the inflator for purposes other than just my car tires, so I wanted it to have an alternate power source. This product comes with a rechargeable battery, or you can use a cable to connect it to the cigarette lighter in your car. I charged the battery, and started reading the instructions. What wasnt clear (maybe only to me) is that in order to use the battery pack, you first have to push a button and slide off the attachment at the bottom of the inflator that has the cable car charger on it. Then you replace that attachment with the battery pack. Press the button to turn it on, toggle through the modes (the first one is bicycle mode), press the + or - keys to raise or lower your intended PSI goal. Then press the trigger on the handle to start inflating. Its fast... and loud. But it gets the job done. I was going to keep it in my trunk, however, its larger than expected. You certainly cant take it with you on a biking trip. This is ideal to take with you if youre going on a long car trip and you might be far from a gas station tire inflator if you need one. Its also really handy at home if you need to inflate an air bed, a raft, or something else thats large, and you dont want to pump the air manually.

This portable inflator works fine and is convenient to hold and use to blow up tires, soccer balls or anything that needs air. It comes with all the tip adapters you will need and the fact that its cordless with a 20V battery makes it very convenient if youre not near an A/C outlet. It also has a 12V cigarette lighter adapter so you can run it off your cars accessory port. It has a USB-C connector to charge the battery and comes with a USB-C to USB-A charging cord but it doesnt come with the wall charger which you will have to purchase separately or borrow one from your cell phone. The lack of a charger and the fact that it doesnt come with a carrying case to store everything in, prevent me from giving it a 5-star rating.

I rated this pump five stars based off what this unit is designed for. First off, this is not a heavy-duty air pump that you are going to replace a compressor with. But if you are realistic in your expectations, overall, I think you would be satisfied. Pros: Light weight tool Easy to read digital battery level indicator, pressure settings, and adjustment settings. You can set the desired pressure, and it stops automatically when it reaches that pressure. Works well for light duty use, such as bicycles, basketballs, possibly rafts, etc Good for topping off filled tires or filling one or two flat car tires. Cons: Loud Not robust for everyday use Not for higher volume tires Low quality feel I have a heavy-duty compressor for my everyday uses, but I wanted a light weight easy to use portable compressor for light duty use that didnt break the bank, something on par with a hand pump that was a bit easier to use, and this fits the bill. I initially used it to top off four already filled car tires from 31lbs to 35lbs. I found this compressor to be accurate and worked effortlessly to top off the tires. I have a truck that the tires are normally filled to 80psi, the pressure was 78lbs and I set the compressor to 84lbs and gave it a try. It was definitely struggling but was able to pump to 82lbs before I turned it off. Honestly, I was impressed it was able to hit that pressure, in a reasonable time frame. I stopped it because it was struggling to the point where I may force it to fail, and I didnt want to do that. This compressor is just not designed for that type of load and is designed to pump at a smaller volume. I think this compressor would fill a flat car tire with no issue, but it will probably take a while. I think it could handle the once in a while flat car tire, but I wouldnt expect it to handle multiple tires in a row, or frequently. I also would not rely on this pump for off road, back country applications, such as lowering and raising tire pressure for terrain. I also wouldnt expect it to fill a paddleboard.

Got this today. I immediately tried it and it now replaces the inflater Ive had for a few years. There are quite a few of these inflaters out there. I like this one for two reasons - it can be used with its internal battery or plugged into your cigarette lighter. The other reason is mentioned in the headline - the connecter is the push and clamp down type of connecter that you see on bike pumps. This is way better than the screw on type of connecter which normally gives me fits, trying to screw it on to the valve stem. My only concern is how long this device will hold a charge. It could spend a year sitting in my trunk until its needed. If the battery does drain down in that time, Im glad the adapter with a decent amount of wire is included. I gave the screw on type of inflater to my son - its his problem now!
