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 like the auto off feature, set a pressure and the pump will turn off at that pressure, automatically. It is convenient to use and nice and light. The charger, battery combo is nice, no charger to loose. All you need is a USB cable. The display is easy to read and bright. The LED light is bright and handy for night time use. This is going to be much more coinvent to use than the battery booster combo that I usually use. Very nice little pump setup with all the fittings you need. Just wish it had a closable compartment to house them in, instead of the clip to the side version, they will get lost that way.

I didnt realize that such a tool existed! I have four cars and on any given week at least one of them has a tire that could be topped up to proper pressure. This is the perfect tool for getting this job done! It works flawlessly. There are a variety of modes depending on whether youre inflating a bicycle, car, etc. It also can change to different pressure units. I LOVE this pump!

I got in my truck yesterday to pick up a take-out sandwich and go visit a friend. My indicator panel told me I had a low air tire. I realized it was time to test my new tire inflator. I chose to use the car adapter because I felt the battery would probably work, but I suspected more than one tire was low, and this is a full-sized pickup truck, not a little car so there’s a fair amount of weight on those tires. I will test the battery option sometime when I am not so hungry, perhaps on my air mattress. So, the cord reached just far enough…barely. I do wish the cord were just a foot longer for the adapter. That, however is my ONLY complaint. With the truck running, I got plenty of power to add 10 pounds to one tire, 3 to another, and the front tire needed 7. The truck’s digital panel tells me how much it reads in each tire, and when I was finished with all 4 tires, the numbers were perfect. The digital readout on the machine doesn’t work perfectly as I pumped, but it’s good enough. The actual tire pressures were where they were supposed to be when I was done. Doing all 4 tires only took maybe 15 to 20 minutes which I considered to be amazing. It wasn’t a fast fill up, but it was efficient and did the job right there in my driveway. I told my friend about it and now he wants one for his truck. This little compressor worked like a charm and could definitely get me out of trouble out on the highway someday. I’m so happy I have it. What a great tool. The photos in the description are accurate and show the product very well. This is something almost everyone should have in their vehicle, but especially those of us with older trucks that are getting the leaky rim syndrome. It was super easy to use…actually easier than the gas station air pumps for me. This woman calls this an excellent product.

This cordless car tire inflator is a very handy tool to keep your tires in good condition. A little heavy but not really a problem. I’ve done the gas station fill ups but much prefer to do it at home and at the same time save money (safer too). It’s very sturdy and works extremely well. Great quality, would definitely recommend.

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

Durable and Strong Easy to follow instructions

I’m impressed with this. I’ve been using it on a tire that has a very slow leak, that I just haven’t had the time to get fixed. The operation is very easy, although the icons for the modes are small and difficult to see if you have 40+ year old eyes. It inflates pretty quickly and isn’t overly loud. I have other tire inflators that will over inflate by .5 psi to account for when you take the inflator off. This doesn’t do that, so just program it for .5 over your target before you start pumping. I like it and will keep it in the Jeep when we hit the road.

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 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.

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!
