It works! My low tire pressure light came on this evening, so I broke this thing out. A couple things to note:1.) Your car has to be running to use it as it plugs into the cigarette lighter socket. At first, I slightly panicked thinking mine didn't have one, but then I realized it's buried deep in the center console area near the phone charger USB ports.2.) It's loud when it runs but you'll be using it outside so maybe just don't use it late at night.3.) It's best to have a tire pressure checker thing in addition to this to verify the reading it's giving you is accurate. It seemed pretty accurate, but I like to double check. It also helped me quickly identify which tire was the problem and then I was easily able to hook up the inflater and get it done. Just a suggestion.I'm not a super auto-savvy person but was able to easily figure how to use this handy device and did it within 10 mins or so.

They should give a good offer on two of these, and here’s why:I read reviews carefully before deciding on a purchase. I also try to determine if the writer might have trouble understanding and/or following instructions.The one problem I noticed most often in the one-star reviews was that the users failed to follow directions.First, you need to keep your motor running while using this device. If you try to use this off the car battery alone, you will risk draining your battery or blowing a fuse.Second, do not try to pump up all four tires at once. These devices run hot. Even the hose was very hot to the touch.So, I purchased two of these machines that would allow me to pump up tires to my 2006 Dodge Caravan alternatively. While I’m pumping one tire, the other device is cooling off.I made certain to touch every part of the machine for a temp check, before reusing it.I guarantee that if I had only purchased one tire pump, and used that pump to fill each tire consecutively and immediately, I would’ve blown out the machine. It begins running hot on one tire. So, with one machine, I would’ve been forced to wait ten minutes between each filling, or risk losing the machine, altogether.Buying two pumps is more expensive, but if I pumped each tire without a cool-off period, I would’ve been forced to buy two anyway, right? AND I would’ve lost one machine in the process…AND I would’ve had to wait a few days for delivery, instead of the recommended ten minutes for cooldown.So by buying two of these, and alternating their uses, one can be cooling down while the other is being used. Easy peasy, bumble beesy!Now, another complaint was the automatic shutoff. Personally, I set it above the recommended PSI level to make up for any air lost during hose removal. So if it says “44 psi”, I set it for “45 psi”. Then I watched the dial as the number climbed. As soon as it reached the number I selected, I shut off the machine.I’m not sure why someone would want to depend on the automativ shut-off to complete the task. The automatic shut off is not intended to be a feature of luxury; it is simply a safety feature, in case the user became distracted. The tire pump, like most machines, should never be left alone to complete a job. In all reality, the tire pump should not require ASO; but the manufacturer included it to compensate for unexpected distractions.So does my ASO feature work? I have no idea, and I don’t care. Because when I run the pump, my total and complete focus is on the pump. If a distraction occurs, I am prepared to turn off the machine so I can deal with the emergency at hand. Machines are not built for the multitaskers.Do I recommend this? I have nothing else to compare it with. I will say the numbers climbed in increments of .05 psi (21.0…21.5…22.0…22.5…23.0…23.5…etc). So the pressure climbed .5 in 6-9 seconds (ie., climbing from, say, 31.0 to 31.5 took anywhere from 6 seconds to 10 seconds, but the average time was 7 seconds). So for a tire to begin 20.0 and inflate to 45 psi (my vehicle was sitting for two years), it took no longer than 10 minutes a tire, and I’m being generous. And it would’ve taken twice as long if I had only purchased one pump.I love this machine. Have you tried filling your tires at Wawa, lately? They’ve cut off all their pumps! Other stations require insertion of coins (who carries around coins, these days?). We are either driving around, trying to find a decent air pump (while driving on low tires, mind you), or waiting in long lines to use the only working pump in town.It’s so much more convenient to fill my tires with two air pumps that I don’t have to wait to use.Once my tires are filled, I can keep one pump in each car, in case a tire gets low. I should not have to fill all four tires while on the road. But if I do, I’ll just have to wait ten minutes as the instructions suggest.This is one if the wisest purchasing decisions I’ve made recently. They also arrived supplied with alternative nozzles for bikes and sports equipment. I’m not sure if I’ll use the air pump for balls and bicycle tires, but it’s good to know I have options.I was not paid or coerced into writing this review.

The AstroAI Tire Inflator is a game-changer for anyone who needs a reliable and portable air compressor. With its impressive 100 PSI capacity and digital pressure gauge, it makes inflating tires quick and hassle-free.
