Just used the compressor for the first time on my tires that should be at 34psi (they were all between 23 and 27 psi). It took less than five minutes per tire. Probably closer to 1 and a half minutes, honestly. Simple to understand and use, compact and lightweight, perfect to keep in the trunk. Highly recommend.

I’ve been using this for a year. So far it works great, and is still working. I use it on a truck, a SUV, and a utility trailer. I live out in the country, and this saves me from driving into town to air up tires. It also saves a lot of money since few places offer free air anymore.

The design is sleek, it’s not too noisy and the quality has been great so far.
I had to use the other night all by lonesome and I felt like a technician lol. It actually worked and my Tyre the right amount of air flow.
Very convenient and useful product to have.

The device worked well on my car tires, no need to use any of the attachments. To use: Start car, plug unit into 12 volt convenience port (cigarette lighter), set memory to pressure level, screw the hose onto the valve stem, flip switch. Very simple, and the default measure is in psi (pounds per square inch), the USA common measure. Other measures, if needed include: “Bar”, “KPA”, and “Kg/cm^2”, for those outside of the USA.
I will say that going up a few psi on the pressure will heat up the unit, specifically the hose: in one case, I went from 26 psi to 33! I simply paused 2-3 minutes in between tires, and let it cool down. The instructions do say to measure the width of your tires, and if they are beyond 28 inches wide, don’t use this unit.
Really, the only complaint I have with this device is that it is pretty noisy, but being a compressor, that really is a minor nit – I just won’t use it at 4 o’clock in the morning!
Full disclosure: I have only had this for a few days, and used it on only four car tires and one bike tire. I’ll try to remember to update my review after long-term usage.

It’s incredible how powerful this tire inflator is! Yes, it’s a bit noisy, but the size and form factor are incredible for the pressure it manages to inflate your car tires. I was skeptical, but it inflates all my tires to 32psi in minutes, with a great auto-stop feature. Very useful and functional, now I have it on my trunk every day!

👍 Pros & 👎 Cons
👍 Pros 👎 Cons
Durable metal build (ToughUltra) No internal battery or AC power—needs vehicle source
Easy auto shut-off and digital accuracy Slightly slow inflation; warned against >15 min continuous use
Compact, good LED light Can vibrate and wobble during operation
Excellent value (~$32‑$40) Maxes out at 100 PSI—not suited for heavy trucks
🧠 Verdict
The AstroAI Tire Inflator Portable Air Compressor stands out as a compact, rugged, and budget-friendly solution for everyday drivers. The metal ToughUltra build and auto shut-off features elevate its functionality beyond basic inflators.

It works well and it’s easy to use. My tire light comes on when the tire hits around 26, and I inflate it to 35. It seems like it takes a long time (I’ve never timed it but I can listen to a couple songs on the radio while waiting), it’s loud, and it heats up. You have to let it cool down after 10-15 minutes of continuous use. For the price, I like it. It works, it’s convenient, and the power cord is long enough that the unit can easily reach the back tires

Air filling is fast and really does the job for the price of the product. Only issue is it gets heated very fast. Good for emergencies. Wire is long enough.

Used this 3 weeks ago on two car tires that needed air. Worked like a breeze. Easy to use, fast inflation time. Love the auto shut off. This lives in my trunk now. Great tool.
