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 used this for the first time recently and it was much easier and quicker than dragging out my pancake air compressor, 50 foot air hose, extension cord, and then waiting for the old compressor to fill itself with air. This thing on the other hand was so easy to use, I just set the desired pressure, connect to the tire and hit the start button and then it shuts off when it gets to the pressure limit. I was not sure how long it would last on a single charge but I needed to air up two trailer tires and 4 lawn mower tires. It easily handled the trailer and the mower so then I topped the 4 tires on my other mower, my car, and my wife’s car. Keep in mind that none of these tires were flat to begin with, but it was able to handle all of that, 2 trailer tires, 8 lawn mower tires, 8 car tires and still had battery life left. Plus if the battery dies, it has a 12 volt cigarette lighter plug you can use instead of the battery. It is lightweight, easy to use. I was quite impressed.

This inflator works great & is compact. Comes with plenty of attachments.

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.

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.

I wanted a small compressor for two tasks, topping off car tires and filing bicycle tires. This one tucks away easily in the car so its always available. Power comes from either the lithium battery pack or a 12v accessory plug adapter. The battery charges via USB-C, preventing the need for yet another charging brick. My existing chargers work well with it. Controls are not obvious but can be figured out. Tested it by topping off the tires on my less used car. One tire was down about 3psi. It took about 12-20 seconds to get it up to pressure. Unit automatically shut off when target pressure was reached. Checked the pressure with a calibrated gauge and it was within 1/2psi. It is noisy but I havent found a compressor yet that wasnt. It comes with adapters for inflating sports balls, floatation devices, and a Presta to Schrader adapter for some bike tires.

This is a great tire inflater. It comes with a battery, a 12 volt adaptor and a couple of adaptors for inflating smaller objects. The hose has a clamp on type connection for tires. I really like the 12 volt insert, it basically is the same size as the battery and slides into the tool just like the battery and has a long cord with a cigarette lighter type 12 volt plug, so you can switch between the 12 volt or battery very easily and the 12 volt cord wraps around the 12 volt adapter and has a space for the plug to sit in. In the pictures I included you can see the battery on the left and 12 volt adaptor on the right. The inflator itself is digital, so you can change between air pressure units, as well as set a desired target for inflation. I set it to 40 psi and hooked it to one of my tires, which read 36 psi and then pressed the trigger and when it started I set the unit down and it inflated the tire until it reached 40 psi. It has some presets for other tires as well or you can set your own target. It also comes with LED lights in the nose of the the tool which I can see would come very useful in the dark. The battery charges with a USB C charging cord so you could charge the battery right in your vehicle (most vehicles today). This is a superior inflation tool to other hand held trigger units I have used, it is digital, has both 12 volt and battery and hands free. The only negative I would have for this is it is on the larger size and a case would have been really nice. I was really torn as to whether this should be 4 or 5 stars, ultimately deciding on 5 stars, while a case would have been nice, it comes with both battery and 12 volt adaptor, digital and hands free while charging. Other similar big name units can cost $30 - $40 and they dont come with the battery which can add a lot to the cost.

This unit is very large. I didn’t expect it to be as big as I thought, it’s as big as a handheld drill. It is rechargeable, and it comes with a battery pack. It’s powerful though, and does the job.

This little thing is pretty amazing especially at its price point. I love that you can set a tire a pressure, my car calls for 41psi so not having to guess is incredible. Its perfect for road trips, its super portable. The light is a smart addition in case you need to adjust your tire pressure in the dark. The fact that it has two power sources is also really cool and very handy. It can be a little loud while its working but Ill take that over having to find a gas station with an air hose any day. If you got a road trip ahead or just like to be prepared this is a must have. Its well made and well worth the money in my opinion. 5/5.

I chose this tire inflator /air compressor because the last one may have been “small and conveniently portable” but it was also such a waste of time and a definite waste of money! As soon as this guy arrived at my residence I opened the package and immediately started to check my tire pressure- which was SO low- then got my tires pumped up to their optimal pressure. MAN, I completely forgot how much better my car drives when my tire pressure is right as rain.

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
