AstroAI Tire Inflator Portable Air Compressor Pump 150PSI 12V DC/110V AC with Dual Metal Motors&LED Light, Automotive Car Accessories&Two Modes for Car, Bicycle Tires and Air Mattresses, Yellow

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.

Very nice and powerful inflator packed in a small package. Works well with power cord and also cigarette lighter charger. Has a nice digital display that shows current tire pressure and you set the target psi and the inflator goes to work and stops automatically when it reaches desired psi in the tire. Works well on my truck and car tires. Would recommend to anyone!

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.

Fantastic, well made unit for the price ! The shipping container is study and the unit well protected for shipment. Comes with manual and a "Thanks for your purchase" asking for your feedback ! . Impressive manufacture quality and design ergonomics are well done. It is plastic of course at this price level, but appears to be plenty rugged enough for every day use. The long ac cord wraps on one end to hold it for transport, as does the air feed hose. The lever lock tire valve connector slips on firmly and locks easily. Has excellent entry controls and a nice LCD display that confirms your entry choices. Nifty bright green LED indicators below the LCD display window confirm in is operating and in use. The bright LED spot light at the end of unit to illuminate work area is bright enough, And it has soft grubber feet that grip the pavement nicely and a soft rubber carry handle for comfort when carrying it. Once you read the manual you should have operation steps down quickly. And it runs at a volume that wont hurt your hearing. This unit offers much performance and flexibility in a easy to tote and store unit. Makes tire air pressure checking and maintenance a snap. I checked the PSI accuracy of the units read-out against my JACO tire pressure gauge and is spot on. All in all, the best auto accessory I have purchased in many a year. Job well done ASTROA1 !!!

It is a well designed product with a perfect number of features. The combo capability of using 110v outlet or car outlet makes it versatile for both shop and portable. It has built in areas to store both electric cord(s) as well as multiple air hose types. I was able to set it to a pre-set PSI level and it automatically shuts off when it reaches that level. Worked well on car tires so expect it will be no problem for other low pressure items like balls, pool floats etc.

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.

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.

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).
