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）

This is a cool little like compressor. It comes with several adapters you might need to blow up a variety different things and is easily packed in a car. It inflates pretty fast and when using the presets wont allow you to over inflate. This has been a great find I only wish it came with a case.

I have a couple normal compressors, but theyre both a hassle to get out when I just need to air up the tires a few PSI. I got the AstroAI Air Compressor with the intention of it solving for that use case. I thought the form factor would be a REALLY nice feature, considering that the compressor can stand upright on its own. The reality, though, is that the usefulness is limited by the really short inflator hose. Even with 245/40-19s its easy for the valve step to be up and out of reach. Ive had to put the AstroAI on an overturned bucket on more than one occasion. While its awesome to not have a 12V cord strung back to an Aux power jack in your car, its good to have reasonable expectations of what you can do with that battery. I ran it down by 3/4 by filling 4 tires from ~35 PSI to 42 PSI. You set inflation pressure on the device, and it shuts off when it reaches the setting. Thats a nice feature because you dont have to keep checking the pressure. Its also good from the standpoint that the inflator is tragically slow. Filling larger tires, or from lower pressures (or both) could be a real problem for this unit. Its worth noting that you probably dont want to run this thing for long periods of time, either, as the compressor just isnt built for that. Speaking of batteries, this battery pack appears to be completely proprietary. While its possible that this will last for years and years, you will still have to (eventually) deal with the battery dying and not holding a charge. Fortunately, it looks like its made of normal 14500 cells, so you can rebuild the thing yourself (if you have 30 minutes, and a good attitude). For seasonal tire top-offs, bike tires, and pool toys, this is a decent occasional use inflator. Conditionally Recommended

This is really high quality and comes with a nice battery that can be charged with USB C. It comes with a cable but no charging brick. It comes with all the air tips and inflator needles etc, but no carrying case. And it comes with an additional auto power plug adapter. Lots of value in this kit but once again no carrying case for all of it.

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.

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 air compressor is a great tool to have in case of an emergency. You can set your desired pressure and the compressor will turn off automatically when it gets to that point. It’s cordless and handsfree, so it’s very convenient. Having a rechargeable battery is a huge plus, but it can also run by plugging into the cigarette lighter, so it’s versatile, too. It’s heavy duty and seem like it should hold up well. I’m happy to recommend this product.

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 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 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.

So my old air compressor I used to carry around was not digital, was much bigger, and kind of annoying to lug around. This, by comparison, is smaller, digital, and fairly easy to use. The fact that it comes with both a battery and an auxiliary socket power adapter is a nice bonus incase the portable battery happens to be dead. Running on battery power, I can just easily walk to each wheel without being tethered by a lengthy power cord to the inside of a car that has to be on. I used it to check my tire pressure and as it turns out, the dealer (who recently did a TPMS sensor recall on my car) had overinflated my tires. Not having to have a separate tire pressure gauge and compressor is also a nice plus (the pressure sensor in my old compressor was very inaccurate) and the quick connect/release is a blessing. Overall, I really like the design and function of this and give it high marks. It has earned a spot as the permanent replacement for my old compressor.
