A much needed accessory for maintaining proper tire pressure.
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!

Reliable, practical, and worth every penny. Highly recommended for emergencies.
This is actually the second AstroAI tire inflator I’ve purchased — the first one I lent to someone and never got back. That alone should tell you how useful it is. I originally decided to buy it after a real situation: when I was leaving work, I found my tire completely flat and had no idea what to do. A coworker helped me using this exact inflator, and it honestly saved the day. I ordered one as soon as I got home. It’s easy to use, portable, and perfect for emergencies. You just plug it in, set the pressure, and it does the job. No guesswork, no stress. Now I keep it in my car at all times. It gives real peace of mind knowing I’m covered if it happens again.

A wonderful product. Price is right
It works terrific. It works as advertised. I like the light so if you’re in your garage or in an area that is dark, you can actually see the plug when you snap the hose on the stem. It automatically shows you just how much psi you have you press the button it fills the tire within a minute, depending on how much air you need, it is compact and small. You have different attachments. No batteries required. A long power cord. A wonderful tool.👍👍

Makes filling up your tires quick and easy!
I have been using this tire inflator for awhile now! I would say it’s fantastic. I use it on a monthly basis on all of our cars and my friends cars. Super simple. No charging! Just plug it in to the 12v and it fills up the tire fairly quickly. The screen and flashlight are very bright and you can clearly see the screen even in daylight! The unit is portable and easy to store. The auto shut off works great and it displays psi, bar, and kpa. The only downside is after doing all four tires on two cars. Maybe adding 10psi each, the plug gets really hot. I accidentally touched it after unplugging and it did burn me but I rarely do that many tires and for it being much cheaper than others, it’s something I can be more careful of. Not a downside but 1 thing to note is based on my other tire gauge it’s about 1.5 psi lower than the screen. Could be air lost during disconnect or just my unit. Not a huge deal All in all, a really good charger, inflates tires fast even on ev’s, the auto shut off is great and I just use the fast clip on plug that doesn’t lose too much air when disconnecting.

Nice air pump
Works just as described. It’s easy to use. I do wish it had a place for the cord to wrap around, is does auto shut off when it gets to the psi you set. It inflates fairly quickly.

Good value add queues
Have had one of these for years. Works well, good size, brings my SUV tire pressure up pretty fast. Easy to use. Does move around slightly while it’s on but it’s not a problem. Loud but hey what tire inflator isn’t?!

Great Inflator
This is a nice tire inflator. You can set the desired pressure and let it do its thing. Ot is pretty quick too. It plugs into a cigarette lighter or 12 volt outlet. The cord is long enough to reach all four tires, but you will need to do one side at a time. The only thing I don’t care for is the removable air hose. It can be a minor inconvenience but overall this is a great tire inflator.

Small, fast, and reliable.
I bought this portable tire inflator because modern cars have decided spare tires are apparently optional equipment, like cup holders in a 1978 pickup. This little gadget lives in my trunk now. It’s about the size of a burrito and works faster than my teenagers when I ask them to do literally anything. Plug it in, set the PSI, press the button, and it politely handles the problem while I stand there pretending I planned ahead. Used it on a low tire in the driveway and again in a grocery store parking lot, which is the natural habitat for tire problems and poor life choices. Both times it worked like a champ. No drama, no wrestling with a gas-station compressor that looks like it survived the Cold War. Is it glamorous? No. Is it the kind of practical tool that makes you feel smug and competent? Absolutely. Bottom line: Small, fast, and reliable. Like the Swiss Army knife of not-being-stranded. Now if someone could invent a device that automatically puts air back in the tires after my kids borrow the car… I’d buy two.

Very bad performance. It takes around 10mins to go from 10PSI to 20PSI.
