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

I’ve purchased two of these now and am really impressed. The price is reasonable, the tire pressure is accurate and I like that I can set the pressure I want and it will fill it and then shut off automatically when done. The display lights up so I can see the numbers. I also appreciate that it plugs into the car for power; I considered ones that have batteries and don’t need power, but to me that’s a lot less reliable; I don’t want to have to remember to charge it. These work perfectly every time and it’s incredibly handy to have, especially in winter when tire pressure drops. I recently took it on a work trip and was glad I did when the tire on the loaner vehicle started losing pressure; turns out there was a nail in the tire that needed repair. Thanks to this gadget, I had no issues getting safely back home.

I would recommend for EVERYONE to keep one of these in their car. It has saved me more than once when I've had a slow leak or just a low tire. I have even gifted these to my friends. Super easy to use, and fills the tires fast. Safer to use than going to a gas station, and those inflators rarely work well, anyway, at least where I live. It's small and doesn't take up much space. I keep it in my trunk at all times, and use it every time my tires need some air. It's a little loud, but it works fast, so that is hardly a bother.

This little thing really works and is amazing! I live in Minnesota so always have to add air to tires every winter. I did all 4 tires in less than 10 minutes. It is very easy to use. It plugs into car outlet for power and set the desired tire pressure and it automatically shuts off when reached. I had a different one that was battery charged and took forever to inflate or battery would be dead when I needed to use. I love that this one is small and easy to store or carry in car. My 16 year old son who knows nothing about car mechanics was able to figure out how to use and filled his own tires.

I purchased this less than three years ago. I think the inflation time is a little misleading, since it operates a little slower than advertised, but it did the job and did it well. Unfortunately, my model just suddenly stopped working this week when I needed it most. I had a bungee cord hook blow out my tire and had to use my spare (full-sized truck tire filled to 35psi). After installing the spare and trying to inflate it, the machine kept stopping and would only work if I was holding the cord in the perfect spot. After a minute of filling, I could hear the sound of the pump change, along with a "hiss". Unfortunately, the pump was still running, but actively draining my spare of all air. Luckily I caught it before it got below 20psi and could limp my truck to the gas station to use their machine. Long story short, it lived for nearly 3 years, served me well, then died when I needed it most. For the price, I feel I got my money's worth, but I would probably buy something a little more robust for the truck in the future.

I have two of these AstroAI portable air compressors, one for each of the vehicles I drive on a regular basis. Access to air compressors and roadside service in the rural areas where I travel is extremely limited. The AstroAI units are extremely light, reliable, and very easy to use when tire pressure decreases and the tire pressure warning light illuminates. Connect the power supply cable and the air line and set the desired fill pressure. The digital display is large enough for my old eyes to read and the auto cutoff feature allows me to take my time disconnecting the air compressor after the desired pressure is obtained no matter how slowly I’m moving. Air flow rate and pressure is capable of increasing my tire pressure at a rate of 1 psi in approximately twenty seconds with initial tire pressure in the 20 to 30 psi range. I added a power cord extension and an air line extension because of my limited mobility. I also purchased a Plano padded case to store my AstraAI air compressor, air pressure gauge, power cord extension, and other accessories. A popular, dependable quality accessory for a great price and free shipping!

The AstroAI Tire Inflator stands out as one of the most valuable purchases I have made on Amazon. Despite its compact size, it delivers impressive power and performance. I particularly appreciate the automatic shut-off feature, which precisely stops inflation once the desired PSI is reached, ensuring safety and convenience. Its highly portable design allows it to be stored discreetly in the trunk, and the overall build quality is excellent. I highly recommend this product to anyone seeking a reliable and efficient tire inflation solution.

This has saved me more than once! Inflates tires very quickly and has auto shutoff when you preset for your max pressure. Plugs into car easily. I had to inflate 4 very low tires on a car that had been sitting for a while and the unit did get a little hot. For quick jobs though, absolutely no issues. Highly recommend.

Great tire inflator! It’s very easy to use and inflates my car tires quickly and accurately. The digital display is clear, and it automatically stops when reaching the preset pressure, which is very convenient. Compact size, easy to store in the car.
