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）

We have a brand name cordles tire inflator similar to this one. Our granddaughter loves ours so much and wanted one like it. I ordered this AstroAl Cordles Tire inflator and I must say I am impressed with its performance. It comes with a battery that charges with a USBC type charger, or you can just attach the charger part that goes directly into the cars lighter. It took me about 7 minutes to get a 13lb flat tire up to 36lbs. It also shut off exactly at 36lbs! It has a digital readout so you can see its progress. It is also hands free so you dont have to stand there and hold the tire inflator all of those minutes. So far, this tire inflator is better than my named brand tire inflator because of all the added features. Of course it comes with attachments for your bikes and balls. I love this tire inflator!

this will be our second purchase of this item.... the delivery was on time, the unit was properly wrapped for shipment and the quality of the unit is excellent.

Its too bulky to stow on my motorcycle, but my full size SUV accommodates it nicely. The quick-connect attaches securely, and is nice and snug - no signs of air leakage once locked. It also releases cleanly with very little air escaping. The LED lights surrounding the hose provide good illumination. The various modes are basically pressure presets; expect to have to adjust them for your specific needs. It does remember the last pressure setting for each mode, which is nice! The auto-shutoff is a very welcome (albeit common) feature for inflators nowadays. I compared the pressure readings to another digital tire pressure gauge that I have; this pump tended to read a couple of tenths above the other pressure gauge. I would consider that within an acceptable margin of error. My SUVs all-terrain tires were all at 30 psi. I first used the pump, on car voltage (with engine running, so about 14.5V), and raised a tire from 30 to 35psi in 4 minutes. I then switched to the included battery (18.5V), and raised the next tire from 30 to 35psi in half the time - 2 minutes. I continued on that second tire up to 40 psi, then raised the third tire from 30 to 40psi in 4:30; fourth tire from 30 to 40psi in 5 minutes. There was only enough juice left in the battery to raise the first tire from 35 to 38psi before the battery ran out. So, the pump does run better on the rechargeable battery than on car voltage; makes sense, since the rechargeable batterys voltage is higher. The battery capacity is very decent; I estimate that you could easily fully inflate one flat car tire with maybe a little bit of juice to spare. All in all, I am pleased with this pumps performance. The battery adds great versatility if youre away from an external power source. I do recommend this product for your consideration.

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]

So far this has worked great. I havent had any flat tires on my car but I have used it to inflate a few bike tires and its working great for that. I have this along with my emergency kit and jump starter in the back of my truck. I may never need it but its nice to have just in case.

This works great on my car and my daughters bicycle tires as well, Didnt take that long to come up to pressure on all 4 tires. Works quiet and does a good job. I would recommend to anyone looking for a small portable compressor.

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.

This little dynamo is a life saver when you find yourself with a flat tire. It has come in handy several times for me so far. I have a slow leak in one of my tires and I have come outside to a tire that was down to 15 PSI. Too low to try to attempt to drive on it, even slowly and no other way to put air in. I can air the tire up from a low of 5 PSI to 36PSI one time on a single charge. A complete lifesaver when in need. Even though the tool looks cheaply made. It has some weight to it and is built from quality material. It is quieter than I had thought it would have been. It’s not a fast process when airing up a tire but it does get the job done. I did find It to be approximately 2 PSI off from what it says it’s at and what my tire pressure gauge says it is.

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.
