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 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.

After some success with the battery (doesnt last long), the 12 VDC charger did not work.

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

The cordless design of this tire inflator is a huge advantage.The built-in rechargeable battery provides ample power to inflate car tires quickly and effortlessly, making it incredibly convenient, especially in emergency situations or when on the road. The compressor delivers a consistent and powerful airflow, The LED flashlight feature is a thoughtful addition, providing extra visibility during nighttime or low-light situations. Easy to use right out of the box.

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

This Tire inflator works extremely well. I wanted a portable one that I could use anytime since I travel long distances. This one was simple enough for me to figure out. I did test it and it has worked well.

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!

Got this tire inflator for my bikes and cars. There are quite a few other battery and wired air inflators on the market, but got this one. It arrived in quite a large box, and was well packed. The pump itself is fairly bulky and includes one battery that can be charged with a USB C charger, and also a battery shaped receptacle that is basically a corded DC plug, to allow plugged in operation. The battery charges fairly quickly, but I think it depends on the type of charger block you have. Mine is a high wattage fast charger and took about 1 hour for the first charge. The operation is very easy, and just requires that you plug in the battery like a power tool, set the air pressure, connect the hose and pull the trigger. It automatically shuts off when the desired pressure is reached. It pumps at a decent pace for the type of pump that it is. It didnt get too hot either when I used it to top off the car tires. I do wish it included 2 batteries. I feel this is a very good light duty air pump.

This cordless pump has been a game changer since switching over from my manual pump. I’ve used this to pump my bike tires and scooter tires, and the pressure gauge seems to be pretty accurate. The best part of that I can set a PSI target and when my tire hits it, the pump automatically stops.

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]
