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 lot smaller than my car air pump. It works well and is easy to pack away. I used it to air up a small ball and when the ball was full it shut off without any issues. Then I used it to air up my daughters little bike tires and set the psi to 40 as the tire pressure and it stopped at 40psi. The accessories are great to have but I wish it had some sort of carrying case. Battery is strong and holds a charge well. Very happy I took a chance with this little thing.

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

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.

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.

I really like this inflator for the programmable function of being able to tell it what pressure I want, and it will set the tire to that pressure. Being able to pick a pressure between 3 and 150 PSI allows me to air up anything from my ATV to the real duels on my motorhome. Where I live in Alaska traveling over the pass in the wintertime sometimes requires you to air down your tires a bit, and this tool lets you do that accurately and quickly, and it is also easy to air them back up when you get to lower elevations and clear roads. The biggest downside to this tool is no included case or storage for it and its accessories. I like tools to have cases. Especially ones that arent likely to get used all the time and get buried in a tool box or trunk. It just makes them easier to store, and keeps them and their accessories organized and in good condition. As much as I like the inflator, its lack of a case will cost it a star. The only other con I can come up with is that while I like the 12v plug adaptor, I wish it came with a spare battery.

This falls under the category of automotive tools that its better to have and not need, then to need and not have. Because at some point, youre going to end up running low on air after running over something unexpectedly. And without fail, the nearest gas station is probably going to have something wrong with its air compressor. The last time we left this at home, it took three stops at gas stations before we found one that actually had a working air pump (one of them was completely missing the hose). So this is a real life-saver if you have it in your vehicle. Works quickly, and is effective at helping to you to gauge the exact PSI of your tire as youre inflating it.

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.

Like many newer cars, ours lacks a spare tire and, instead, includes only a 12v compressor. Sadly, the tires are always losing air no matter how many times we take it in for repair So, the included compressor gets used — and cursed at for its flaws. This battery operated compressor is a huge improvement. Most importantly, I don’t have to fool around with wires and cigarette lighter sockets (unless I use the included 12v adapter instead of the battery). Next, it’s automatic. I can set it for a precise pressure, start it and go sit in the car until it stops. There are several presets, plus it uses the most recent setting if different. All four tires come out exactly the same without any fooling around. My tpms reads two psi lower than the compressor setting and I don’t know yet which is correct, but I’ll figure it out. It charges and pumps slower than I hoped (but not slower than any other 12v compressor I have used), but the time saved by not having to adjust the pressure or stand outside monitoring it more than compensates. The screen is easy to read and the settings are simple and obvious. There is always room for improvement and this compressor is no different. I would like to see a compact case or sack to protect it. I also would like it if the accessory connectors could be secured by clipping onto or screwing into the casing. (It looks like something like that was contemplated but not actually accomplished. There is a place to clip the hose. There are a few other fittings but they aren’t really secure.) The 20v battery looks remarkably like a Dewalt, but sadly it is not identical, so I cannot substitute batteries/chargers I already have. No doubt there are legal reasons for this. The battery, however, is lithium and will receive such light use that it should outlast the car. If the battery eventually fails, there is always the 12v adapter.

This tire inflator works great - and for a multitude of things! We have in our camper, should we need it traveling - but it’s also super helpful for pools, balls, etc. So happy we came across this!

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