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 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.

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.

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.

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.

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.

This air compressor is great. Just tell it what you want you tire pressure to be and it pumps it to that and shuts off. Comes with a rechargeable battery and also a hook up to run it straight from your vehicle. The only knock I have on this item and the reason it is not getting a 5 star review is I wish it came with a carry bag or case and not just the box it came it.

Got this today. I immediately tried it and it now replaces the inflater Ive had for a few years. There are quite a few of these inflaters out there. I like this one for two reasons - it can be used with its internal battery or plugged into your cigarette lighter. The other reason is mentioned in the headline - the connecter is the push and clamp down type of connecter that you see on bike pumps. This is way better than the screw on type of connecter which normally gives me fits, trying to screw it on to the valve stem. My only concern is how long this device will hold a charge. It could spend a year sitting in my trunk until its needed. If the battery does drain down in that time, Im glad the adapter with a decent amount of wire is included. I gave the screw on type of inflater to my son - its his problem now!

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.

After some success with the battery (doesnt last long), the 12 VDC charger did not work.

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.
