AstroAI Tire Inflator Portable Air Compressor Pump 150PSI 12V DC 110V AC with Dual Metal Motors LED Light

I've had this air compressor for 3 years now. Its reliable and very easy to use. Reads the current PSI and allows you to program your target PSI. Then automatically stops when the target is reached, so there's NO room for overfill error. I primarily use it to top off my vehicle tires, although it comes with multiple nozzles and doodads. Its compact and easy to stash in the trunk, under the seat or wherever. I say its the best thing since sliced bread and every Woman should have one in her car trunk. It keeps me from having to go to the tire shop for air checks and fills, in between rotations and maintenance. I like it so much that I just gifted one to my daughter for her birthday. She's a new-ish driver and learning to safely maintain her car...as all Women should be able to do these days! I'll be sending one to my Mom next! Thanks for a dependable and affordable product.

Works great - exactly as advertised! I used it on a slow leaking front car tire and it was fast, accurate and most of all, super easy to use. Read more

Works as advertised. The option to power off AC or DC, and precision inflating to 0.5psi were important features to me. I used it to inflate bicycle tires and balance car tires to the right pressure. There is a row of LEDs that show you how close it is getting to the set pressure, very handy if you don't want to stand directly over the unit to read the display. Lots of room for cord storage and the AC cord is decently long. I did still need an extension cord though. I did not test the low pressure/high volume option. My only gripes are the user manual and adapter storage. The manual doesn't give you a lot of help but after some fiddling you can figure things out. Like if you are inflating multiple tires, you have to switch the unit off and on to get it to go again once it has reached its set pressure in the first tire. Which I did using the AC/DC power selector switch as this seems to double as a power switch. And, it doesn't explain how to store the adapters. There are clips at one end obviously meant for them, but after 10 minutes of Tetris-like playing I discovered there is no combination that will store them all. You have to attach one to the pressure hose, and the other 4 will fit into the storage clips in 2 pairs. Read more

I tested it to inflate my bike tires to 47 PSI and it was quite fast. I also tested it on my SUV tires up to 32 PSI; it took a bit longer than the bike tires, but it inflated them without any issues. Toward the end it got a little warm near the air hose, so it seems best for light-duty use, but it does its job perfectly. I tested it with both 120V and 12V and everything worked great. Totally recommended. Read more

I'm using it for few months already. It was easy to use and it works great. I'm very satisfied with the product quality. I tried few different tire inflators. This one is the best and worthy to keep it. Read more

This is the second AstroAI tire inflator/portable air compressor I bought. It is a gift for a relative - my first one has been outstanding and I use it whenever I need to add air to my vehicle tires. Very easy to use - I actually plug it in in my garage outlet - and am spared having to wait at various gas stations for others to use the air there. It runs on a vehicle cigarette lighter or an electrical outlet at home - I love it! Read more

The pump is a reliable tool to do emergency fill-ups with the use of the cigarette lighter attachment, or filling completely flat tires using the AC feature. It is sturdily constructed and portable. Read more

UPDATE: November 9, 2025 A couple of weeks back, I was contacted directly from AstroAI Customer Service via Amazon Message Center. They wanted to apologize for the failed pump and that customer satisfaction was priority one. They offered to send me a replacement pump at no charge (nor did I need to return the original pump). I received the new pump within 2 days. I can’t thank AstroAI enough. Their customer support was nothing short of excellence. Hopefully the new replacement pump will work out as it is compact and has a lot of great features. On my own accord and for reasons noted above, I have changed my original product rating from 2 to 4 stars. ORIGINAL REVIEW The tire inflation mode worked well three times, but since then, the pump has gone kaput. I had used the unit on three different occasions and on each occasion to bring a single vehicle's four tire pressures to the recommended cold inflation psi (each tire needed about 3-5 psi). All went well; but now when connected, the pump attempts to inflate just to cut off within seconds. In addition, the pump no longer reads the current inflation level of the tire in psi or otherwise. The external air pump for floats, etc. is still working. A sad situation, as the unit is just over a month old (at the time of this review). Read more
