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）

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.

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!

I love the convenience of this rechargeable air compressor. I check my tire pressure regularly and add air as necessary. The preset psi works great to shut it off when you reach the right pressure, and I confirmed the accuracy with a separate tire gauge. With my old unit, I had to plug into my car battery, and it took much longer to air up the tires. I had to worry about blown fuses, and the cord was a pain. None of that hassle with this one. It comes with attachments to fill other things as well. There is a needle for balls and a rubber tip for filling inflatable pools/toys. I have this in my garage right now, but it would also be good to keep in the trunk for emergencies. The light is not the brightest, but its enough to help you see what youre doing. As much as I like this tool, I took a star off because there is no way to keep all of the accessories together. You cant even clip them on to the unit itself. The lack of a case to protect the compressor and organize the parts is quite disappointing, and I will have to find something to use for this purpose.

I got in my truck yesterday to pick up a take-out sandwich and go visit a friend. My indicator panel told me I had a low air tire. I realized it was time to test my new tire inflator. I chose to use the car adapter because I felt the battery would probably work, but I suspected more than one tire was low, and this is a full-sized pickup truck, not a little car so there’s a fair amount of weight on those tires. I will test the battery option sometime when I am not so hungry, perhaps on my air mattress. So, the cord reached just far enough…barely. I do wish the cord were just a foot longer for the adapter. That, however is my ONLY complaint. With the truck running, I got plenty of power to add 10 pounds to one tire, 3 to another, and the front tire needed 7. The truck’s digital panel tells me how much it reads in each tire, and when I was finished with all 4 tires, the numbers were perfect. The digital readout on the machine doesn’t work perfectly as I pumped, but it’s good enough. The actual tire pressures were where they were supposed to be when I was done. Doing all 4 tires only took maybe 15 to 20 minutes which I considered to be amazing. It wasn’t a fast fill up, but it was efficient and did the job right there in my driveway. I told my friend about it and now he wants one for his truck. This little compressor worked like a charm and could definitely get me out of trouble out on the highway someday. I’m so happy I have it. What a great tool. The photos in the description are accurate and show the product very well. This is something almost everyone should have in their vehicle, but especially those of us with older trucks that are getting the leaky rim syndrome. It was super easy to use…actually easier than the gas station air pumps for me. This woman calls this an excellent product.

I was looking for a tire inflator that I could keep in my car, but also use for the riding mower and other things. This is exactly what I wanted. It comes with two batteries. One that charges in a car cigarette lighter and one that charges with a USB-C cable. One you are ready to go you just program in the PSI you want and pull the trigger. It pressures up tires in no time at all. This is a great item that I really recommend.

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 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 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.

So happy, I don’t have to manually pump air for my bike and scooter. My previous pump could not get a consistent seal on presta valves and it sucked. This pump creates a god seal on presta cakes (with adapter) and schrader valves. I pumped my bike to 75 psi and scooter to psi and it stopped automatically at my setting. Can run off of battery off of the car battery. The battery is charged via USB-C. So that makes it easy. Wish I could create more than one custom setting. Also wish there was an Adapter to pump my standup paddle board.

This is awesome for the average homeowner who needs to inflate bicycle tires and occasionally inflate a car tire. Dont know about you, but every time I go to the gas station to fill my tire (after the tpms light comes on), the air compressor either costs money, is broken, or there is a long line. Hah! No more of that. Just attach this unit to your tire and the led shows you the current tire pressure. Enter in the pressure you want and click the trigger and it inflates the tire to that pressure and automatically shuts off. I checked pressure with a second tire gauge afterwards and it was spot on. So easy that I am looking for other tires to fill! In my opinion, this would make a great housewarming gift for someone to add to their tool collection.
