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）

This is a lot smaller than my car air pump. It works well and is easy to pack away. I used it to air up a small ball and when the ball was full it shut off without any issues. Then I used it to air up my daughters little bike tires and set the psi to 40 as the tire pressure and it stopped at 40psi. The accessories are great to have but I wish it had some sort of carrying case. Battery is strong and holds a charge well. Very happy I took a chance with this little thing.

This is really high quality and comes with a nice battery that can be charged with USB C. It comes with a cable but no charging brick. It comes with all the air tips and inflator needles etc, but no carrying case. And it comes with an additional auto power plug adapter. Lots of value in this kit but once again no carrying case for all of it.

Ive at tried a few portable pumps, but this ones power blew me away. You can easily pump up bike, car, scooter tires in no time. I use it to pump all my vehicles. Also love the multiple presets for bike, scooter, car, ball. Battery lasts super long, have used it to top off my car tires, few bike tires etc, battery hasnt even dipped. Also has 12V power adapter to run off your cars 12V port. Takes prob 3-4 hours to fully charge, but lasts super long. Pros Plenty of power, 20V 37Wh Lithium battery Lightweight Multiple attachments for presta, inflatables, etc Charges w/ USB-C

Awesome little air compressor! In the past I would have to stop at a gas station and hope their air compressor worked. Or pull a heavy air compressor from the shed and carry it 100 ft across the yard! Not to mention, low tire pressure almost always happens when it is raining or you dont have time to deal with the drama! This will make it so much easier for me to air up my tires! (I filled my tires to 32 PSI) * Was easy to use and came with an instruction manual. The manual was easy to understand and well written. * Has 4 modes: Bicycle mode, Motorcycle mode, car mode and Basketballs mode * Has 4 unit modes: PSI, Bar, kPa, kg/cm * You can set it to the PSI pressure you want and it automatically shuts off when the pressure is reached. * Has a battery life indicator on the screen, which is really helpful. * Has 6 LED lights on the front, for filling tires in the dark. * When you hook it up to a tire it immediately gives you a pressure reading on the tire, to let you know if you need to fill it. This was helpful, because my son over filled my back tires and I was able to slowly remove the extra pressure. * Comes with a Lithium battery and a 12 Volt cord that is installed in a battery shaped piece of plastic. Which is useful, because you can slide on the battery or slide on the 12-volt cord, depending on your needs. * Comes with some attachments for filling other things like basketballs. *** Update*** My Sons best friend just used this to fill the tires on his truck to 44 PSI. He used it to test his tires level and to fill one tire. He said it worked great, but it was slow and the hose got hot while filling it.

Pros: Up To 150 PSI Rechargeable Portable Lightweight Easy To Use Multiple Adapters 4 Presets Manual Set From 3 - 150 PSI AC / DC Power Supply Auto Shutoff LCD Screen Cons: No Storage Pouch What I received in the package: 1 x ASTROAI Cordless Air Compressor 1 x Cigarette Outlet Power Adapter 1 x MicroUSB Charging Cable 1 x Inflation Needle 1 x Valve Extender 1 x Replacement Fuse 1 x User Manual This ASTROAI Cordless Air Compressor product I ordered to give me a back up if I needed something on the road. I drive a Jeep off-road and sometimes it would be easier to grab a cordless air compressor than pull out the big dog. Or just if you need one in an emergency to get you back on the road. In testing, I let 10 PSI out of each tire and then aired them up with the compressor. It took roughly 70 seconds per tire or about 7 seconds per pound. This is a handy little compressor to have around. The 20V battery is powered by a 2000 mAh Lithium Ion power cell that has a continuous working time of 15 minutes. The compressor will auto shutoff once it hits the inflation value that you enter. Great feature so you don’t have to 1) baby-sit the compressor and 2) don’t have to worry about over inflating something. The LCD screen is small but clear and the control buttons are easy to use. What is also nice is that you can go cordless with this tool. But still have the option of using 12V DC from the car battery via the cigarette outlet if you need it. The compressor also has an LED light in case you need it at night time. The air feed tube has a few attachments for various different needs. My only real gripe is that it doesn’t come with a storage pouch to keep all the components together. That is just a must for something like this. Also, the air line is just slightly too short to be able to reach the valve if it is at the top of the wheel. I will not sit flat on the ground which could put wear and pressure on the end points. It would have been nice if this was 1 - 2” longer. I appreciate you taking the time to read this. All in all, this portable compressor worked well in my testing. Only time will tell if it is going to be something that is durable and lasts the test of time. But so far it has functioned without issue and has been efficient and reliable. Hope this information was helpful. [5 Stars]

This is a great tire inflater. It comes with a battery, a 12 volt adaptor and a couple of adaptors for inflating smaller objects. The hose has a clamp on type connection for tires. I really like the 12 volt insert, it basically is the same size as the battery and slides into the tool just like the battery and has a long cord with a cigarette lighter type 12 volt plug, so you can switch between the 12 volt or battery very easily and the 12 volt cord wraps around the 12 volt adapter and has a space for the plug to sit in. In the pictures I included you can see the battery on the left and 12 volt adaptor on the right. The inflator itself is digital, so you can change between air pressure units, as well as set a desired target for inflation. I set it to 40 psi and hooked it to one of my tires, which read 36 psi and then pressed the trigger and when it started I set the unit down and it inflated the tire until it reached 40 psi. It has some presets for other tires as well or you can set your own target. It also comes with LED lights in the nose of the the tool which I can see would come very useful in the dark. The battery charges with a USB C charging cord so you could charge the battery right in your vehicle (most vehicles today). This is a superior inflation tool to other hand held trigger units I have used, it is digital, has both 12 volt and battery and hands free. The only negative I would have for this is it is on the larger size and a case would have been really nice. I was really torn as to whether this should be 4 or 5 stars, ultimately deciding on 5 stars, while a case would have been nice, it comes with both battery and 12 volt adaptor, digital and hands free while charging. Other similar big name units can cost $30 - $40 and they dont come with the battery which can add a lot to the cost.

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 air compressor is a great tool to have in case of an emergency. You can set your desired pressure and the compressor will turn off automatically when it gets to that point. It’s cordless and handsfree, so it’s very convenient. Having a rechargeable battery is a huge plus, but it can also run by plugging into the cigarette lighter, so it’s versatile, too. It’s heavy duty and seem like it should hold up well. I’m happy to recommend this product.

I tested two entirely different types of this product at the same time. The other, a slightly less expensive u it, was more user friendly and simpler to understand and use. The one you are considering here seems better made and designed, but it is harder to understand. Another drawback is that the first time I used it, it did not automatically turn off when it reached the preset PSI. I’m not sure why that is, and I’m still messing around with it to figure this out. The included instructions offer no insights to this. Otherwise, it is powerful and very well made.

I do a fair amount of driving. It always concerns me that I am going to have to replace a tire on the side of the road due to an errant nail, and because I cant safely drive to the nearest station. So when I ran across the AstroAI cordless Tire Inflator, I knew I had to have it. This nifty device has a Li-ion battery that holds a charge for considerable time, to be ready when and if you experience an unfortunate event on the road! Admittedly, I used this only briefly so far to test it out. I have to wait for a REAL flat tire in order to put it to a REAL test! However, for the purpose of testing and preparedness, I did go ahead and deflate my car tire a few PSI, then used this device to refill it. The battery held great! Here is the best part. Lets say you forget to charge the battery. That is OK - if you have this product, you can simply connect it to the car lighter port and it works flawlessly. I only have one small thing that would improve this product to perfection. It should come with a bag. There is a tire inflator, a rechargeable battery, and a few connectors. When I put this in my trunk, it would be nice for it to stay all in one bag. Inevitably I will be searching for that battery (or connector) when I need it. I could also supply my own bag... yes. There is that. This is a great device for giving you peace of mind on the road. I highly recommend it. *** OH SO! *** Peace of mind for the road Multiple ways to inflate a flat tire *** SO-SO *** Should have a bag for the trunk
