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）

Every vehicle should have a little air compressor in it. This is a nice portable air compressor that will save you in a time of need. I go camping a lot on rough roads and Ive had a few slow leaks and having an air compressor in your vehicle will save you in a time of need.

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 is a great air compressor for the price. I like the two options to operate the air compressor without the need to purchase any accessories. One option is the rechargeable 20V battery for extreme portability. The second option is via a 12V auxiliary power outlet (the cigarette lighter port), which is connected to a dummy batter (which may also be an inverter since the 20V battery and the 12V DC plug provide the same PSI). Previously I mentioned that the battery provides maximum portability for the air compressor, but the DC plug has a very long cord, which also aids its portability. This air compressor is not as loud as some other portable air compressors I own, but it still has some volume to it. I really like the safety/intelligent features of this air compressor. I like being able to attach this to my tire in the garage, set the desired pressure, and know it will automatically shut off when the preset pressure value is reached. This feature is beneficial for individuals that want to avoid the loud noise of any air compressor (remote or wired) altogether. One negative is that this does not come with a charger for the 20V battery, but it can be charged with a 5V/2.4A power adapter. I did want to correct the Sellers page, which indicates that this air compressors battery is charged via Micro USB because the 20V battery is actually charged via USB-C and NOT Micro USB. 5 Star Product

This review is for: AstroAI Tire Inflator Air Compressor Cordless Car Tire Pump with 20V Rechargeable... Pros: 1) Overall, well-designed and works well. 2) Convenient feature that allows you to set the needed pressure. Inflator shuts off when that pressure is reached. Cons: 1) Appears to have a proprietary battery. Currently, one does not need a battery while its new, but one could in the future. Not sure that a replacement is available. Not having a replacement battery if needed, could render the inflator unusable. 2) A bit on the large side compared to other inflators. May be difficult for some to hold easily, but his is NOT a dealbreaker. I will update this review if needed based on positive or negative experience(s) after further use of this product.

This inflator is great. Lightweight but powerful enough to inflate a tire on my truck in under 8 minutes. Attach to tire, hit the trigger and walk away. The preset pressure will turn off the pump when reached. Easy to set pressure at what ever you want. Comes with lithium battery last will last over 10 minutes of continuous use. Need more? Pull the battery and plug in the included cigarette lighter plug and keep going. Big enough to be substantial, but small enough to be able to carry in your car at all times. Has very bright LED lights so can also be used in the dark or as a flashlight in a pinch. I get thumbs up on this one and look forward to keeping it in my truck for emergencies.

Small, portable and so handy! Really like the idea of being able to inflate my tire if it is low without worring about getting my car to an air pump. This pump isnt heavy, its very easy to use, easy to attach and lets you set your pressure with auto shut off. It came in handy when my tire was low due to a nail and my husband was working, I was able to easily fill up my tire and take it to get plugged. It saved so much time, glad I had it.

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 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!

This is pretty convenient since my car’s 12 volt plug doesn’t work. I can just pop the battery on this and use it. The battery life is good and only dropped one bar after airing four car tires. It auto fills to a certain psi which is also pretty convenient. My husband said it’s pretty accurate, just off a little bit. It’s pretty bulky but it’s designed to look like a power tool so it’s whatever. There is an area on the side that has what might be to hold the tips or something, I’m not sure. But they’re little plastic rectangular shapes and really sharp. I actually cut my finger the first time I held this. We just sanded the corners, but what’s the deal there? Otherwise, I like this. One star off for the assault.

I tested two entirely different types of this product at the same time. The other, a slightly less expensive u it, was more user friendly and simpler to understand and use. The one you are considering here seems better made and designed, but it is harder to understand. Another drawback is that the first time I used it, it did not automatically turn off when it reached the preset PSI. I’m not sure why that is, and I’m still messing around with it to figure this out. The included instructions offer no insights to this. Otherwise, it is powerful and very well made.
