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 like the auto off feature, set a pressure and the pump will turn off at that pressure, automatically. It is convenient to use and nice and light. The charger, battery combo is nice, no charger to loose. All you need is a USB cable. The display is easy to read and bright. The LED light is bright and handy for night time use. This is going to be much more coinvent to use than the battery booster combo that I usually use. Very nice little pump setup with all the fittings you need. Just wish it had a closable compartment to house them in, instead of the clip to the side version, they will get lost that way.

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.

Very convenient platform. I use it on my cars, trucks, and miscellaneous household items.

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.

I got this tire inflator to replace a previous one I had that never worked, which itself had replaced one that died after a couple of uses. This one looks more promising. It is working well so far, and it has a much more capable battery. Once charged, it was able to put 3-5 lbs of air in each of my four tires to bring them up to where they should be. It seemed to have plenty of charge left, but I had no way of testing to be sure. But the fact that it was able to do this was enough for me. If it should run out of juice, you can connect it directly to the 12v cigarette lighter in your car to power it. It includes a USB cord for recharging. You can plug it into any USB charger, but be aware that if you use a charger designed for a cell phone, it will take a long time to charge. I recommend something more powerful, such as an iPad charger. I only gave it 4 stars because it has not built-in storage for the accessories, nor does it even include a carry bag to store them. So they will be lost in no time, and Im sure I am not the only one who feels that way.

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.

Just got it a couple days ago. Works great! Perfect for our cars & SUVs.. we can even inflate our bicycles! It’s a bit loud but I guess that’s because of the compressor inside. Overall great product and great price!

This handheld air compressor is seriously the coolest. My husband has a large air compressor in the garage but it feels intimidating to use, and sometimes I cant get whatever it is I need to fill to the garage. This handy compressor is so user friendly and easy. It comes with different attachments so you have what you need to fill a tire, ball, or whatever. The rechargeable battery is so convenient and if it happens to be dead when you need to inflate a car tire, you can plug the attached power cord into the lighter socket and youre good to go. Also, you could charge the battery with the provided USB-C cord if you are set up that way in your car, but it will take a little bit (particularly if youre in a hurry). The settings are simple to understand, as well. Theres a screen that shows four pre-set options for bicycle, motorcycle, car, ball and you can also pick from PSI, Bar, kPa, kg/cm2. If you dont want to use a pre-set option, you can either set your own pressure limit, or just press the button and fill until you want to stop. When using a pre-set option, or setting your own pressure, it will automatically stop when it fills to the pressure its set at. If its dark outside, there is a light button to illuminate the area so you can easily connect to the valve. Its pretty lightweight, considering it has a battery attached to it, and easy to handle. It feels durable and well made; I appreciate how easy it is to use every time I need 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

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]
