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 winner. Lightweight, quick charging, and powerful. I just got back from a trip to the Outer Banks and used this pump to refill my tires after driving on the beach. I’ve used other pumps in the past, but AstroAl put together the top dog here. I won’t leave home without it.

This is a great air compressor for the price. I like the two options to operate the air compressor without the need to purchase any accessories. One option is the rechargeable 20V battery for extreme portability. The second option is via a 12V auxiliary power outlet (the cigarette lighter port), which is connected to a dummy batter (which may also be an inverter since the 20V battery and the 12V DC plug provide the same PSI). Previously I mentioned that the battery provides maximum portability for the air compressor, but the DC plug has a very long cord, which also aids its portability. This air compressor is not as loud as some other portable air compressors I own, but it still has some volume to it. I really like the safety/intelligent features of this air compressor. I like being able to attach this to my tire in the garage, set the desired pressure, and know it will automatically shut off when the preset pressure value is reached. This feature is beneficial for individuals that want to avoid the loud noise of any air compressor (remote or wired) altogether. One negative is that this does not come with a charger for the 20V battery, but it can be charged with a 5V/2.4A power adapter. I did want to correct the Sellers page, which indicates that this air compressors battery is charged via Micro USB because the 20V battery is actually charged via USB-C and NOT Micro USB. 5 Star Product

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!

Every vehicle should have a little air compressor in it. This is a nice portable air compressor that will save you in a time of need. I go camping a lot on rough roads and Ive had a few slow leaks and having an air compressor in your vehicle will save you in a time of need.

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.

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]

I live in a city where all of the gas station air pumps are always broken, and when they arent its a line to use them. And thats after driving to the gas station in the first place. Having this pump is 100xs more convenient. I keep it in my trunk with the power adapter. When the weather changes cold/hot and my tires lose pressure in back up and going in about 10 minutes. Less time than driving to a pump! Its a great quality pump, and similar priced to the big tool brands (the ones that dont include batteries) but comes with a lot of accessories! Well worth having on hand!

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.

I really like this inflator for the programmable function of being able to tell it what pressure I want, and it will set the tire to that pressure. Being able to pick a pressure between 3 and 150 PSI allows me to air up anything from my ATV to the real duels on my motorhome. Where I live in Alaska traveling over the pass in the wintertime sometimes requires you to air down your tires a bit, and this tool lets you do that accurately and quickly, and it is also easy to air them back up when you get to lower elevations and clear roads. The biggest downside to this tool is no included case or storage for it and its accessories. I like tools to have cases. Especially ones that arent likely to get used all the time and get buried in a tool box or trunk. It just makes them easier to store, and keeps them and their accessories organized and in good condition. As much as I like the inflator, its lack of a case will cost it a star. The only other con I can come up with is that while I like the 12v plug adaptor, I wish it came with a spare battery.

This is pretty convenient since my car’s 12 volt plug doesn’t work. I can just pop the battery on this and use it. The battery life is good and only dropped one bar after airing four car tires. It auto fills to a certain psi which is also pretty convenient. My husband said it’s pretty accurate, just off a little bit. It’s pretty bulky but it’s designed to look like a power tool so it’s whatever. There is an area on the side that has what might be to hold the tips or something, I’m not sure. But they’re little plastic rectangular shapes and really sharp. I actually cut my finger the first time I held this. We just sanded the corners, but what’s the deal there? Otherwise, I like this. One star off for the assault.
