AstroAI Tire Inflator Portable Air Compressor Air Pump for Car Tires-Car Accessories, 9.8Ft Cord-12V DC-Powered Auto Pump with Digital Pressure Gauge, Emergency LED Light for Bicycle, Balloons, Yellow

This tire inflator has already saved me a few times. It’s small enough to store easily in my trunk, but the build quality feels solid—not cheap or flimsy like some other portable pumps I’ve used.It’s very easy to use: just plug it into the car’s 12V outlet, set your desired pressure, and it shuts off automatically when it’s done. Inflation speed is surprisingly good for such a compact unit—perfect for topping off tires or inflating sports balls.The built-in pressure gauge is accurate, and the emergency LED light is a nice bonus for nighttime use. Portability and functionality make this a great value for peace of mind on the road.

I’ve had this little gem for just over a year now and I’ve used it a handful of times and every time I use it I think to myself “this little thing is amazing, I need to leave a review for it” but alas, I always end up forgetting. Not this time! This portable compressor is amazing. It’s compact, efficient and accurate. I love the backlit display with readout that shows you what the current PSI is when you initially connect it and while it’s working. The display is easy to see from a distance. I live in a an area with extremely cold winters so I appreciate being able to hook this up at home in my heated garage where I can essentially “set it and forget it” thanks to the pre programmable feature where you set your desired pressure and the machine automatically stops once reached. It stands on its own while working and I’ve never had any issues with it tipping over. No more standing outside in below zero temps and having to search for a pressure gauge at a gas station to add air to my tires. The cord is plenty long enough to reach all 4 tires from the plug in my center console. The machine is extremely easy to use and it remembers the PSI that was previously set or programmed every time you use it so it doesn’t need to be reset each time. The included flash light feature is nice although I’ve only needed to use it once. The only thing I wish it had that it doesn’t is some sort of a storage/carrying case since I keep it in my vehicle at all times in case of emergencies, so a nice little zippered bag with handles or something would be great. It also comes with a handful of different types of valves for various uses but so far, I’ve only used the one to add air to my car tires. Every time I use it, it works as good as the very first time. If anything ever happens to it and I need to buy a replacement, I wouldn’t hesitate but may look for one that has the option to plug into a wall outlet in addition to the car port, if such a thing even exists. Overall I highly recommend this for its easy of use, size, price point and convenience. I’m very happy with my purchase.

I rarely write reviews (mostly just read them before buying, myself,) but this tire inflator impressed me so much, I wanted to share my experience with this product.Pulling it out of the box, I had some doubts; the inflator is very compact and not remotely heavy. I couldn't imagine it would be powerful enough to inflate the tires of my SUV. I read the manual, which included graphics of each step, and simple directions on use. It comes out of the box ready-to-use. There's also a little bag of accessories to modify use for things like balls, as well as a spare fuse (we didn't need any of the extra items.)Following the directions, I started my vehicle, plugged in the 12V adaptor, and turned it on. The LED light was already set to on; I was operating it during the day, but see this would be a very valuable little feature if needed roadside or in the dark. I set the desired pressure, connected it to the tire stem, and turned it on. It's surprisingly loud for its size, but not painfully so. I was impressed at how quickly it inflated the tire from completely flat. In well under 8 minutes, the unit had the tire up to 20PSI. We stopped there, because we had another tire to inflate, and this was more a proof of concept run.It's lightweight, and as there is snow on the ground here, I held it by the handle. Likely due to the outdoor temps, not being on the ground, and the brief time we used it, the unit did not get hot (the manual says to not use for longer than 15 minutes per session, with at least 10 minutes between sessions, to not overheat it.)It does exactly as promised, and the petite size makes it perfect to stash in the trunk for emergency usage, even if you aren't dealing with a chronic slow-leaking tire. I've actually given this one to my daughter, and am buying a second to store in my trunk. This is as valuable as keeping jumper cables in your trunk, if not more so, especially for the price.I hope this is helpful to anyone waffling on purchasing this, concerned it is too good a price to be a useful tool. I am exceedingly pleased with our purchase.

This item replaced a 4 year old pump that stopped working. This new one is similar, but fills tires faster. I like the auto-off after a preset pressure is reached, but noticed it varies by as much as 1.5 psi. I especially like the add-on accessories, including a quick-connect Schrader valve. Removed one star due to inconsistent pressure and the LED display only shows one pressure (actual vs preset). It’s not clear which is displayed, which is confusing. The old pump displayed both.

This little machine has saved my wife on numerous occasions. (She has the worst luck with leaking tires) its light, small and fills up a flat tire pretty quick. Has a digital display to see what the psi is and you can even set it to auto stop once it reaches a certain psi level. Have been using for a few years now so if you treat it right it will last a long time. I didnt think it would be such a worthy product at such a low price, but i have since been pleasantly surprised.
