AstroAI Digital Tire Pressure Gauge with Inflator, 3-250 PSI ±1% Precision

I bought this item and it was accurate and worked properly. I stored it in my truck and about two months later when I went to use it the display screen was blank. I e-mailed customer service on Wednesday, they replied on Thursday. I sent them additional info and I had a completely new item on Saturday. You can't beat that kind of Customer Service!! A+++

FINALLY...a gauge that agrees with the Tire Pressure Monitoring System in my 2018 Cadillac ATS. I don't often write reviews, but this is a solid product that works. I've been through many gauges over the years, mechanical and electronic, trying to find one that agreed with at least one of the others. I currently have five, and the the closest two are two pounds apart. With the ATS, which shows each tire's pressure, I had to use a "fudge factor" added to the gauges' reading in order to get the correct pressure in each tire. No fudge factor needed with this gauge--the display in the car and gauge face match, giving me confidence that my tire pressure is correct. Bonuses: 1) I check the TP on each of my vehicles monthly; one small sports car (small tires), one truck (big tires), and the Caddy (medium tires compared to the others) (yes, I've been blessed), all using the two gauges that most closely agree. With this gauge, the sports car's tires were five to ten pounds low and the truck's tires were three to five pounds low (the truck has a TPMS, but no individual display). I'm confident that these vehicles now have the correct tire pressure, too. 2) This is a well-made unit, likely to last. 3) It does require two AAA batteries, but they're very easy to replace; batteries are included. 4) It's very easy to use, with a pressure release valve to let out small amounts of air if the tire is overfilled. 5) They also included a good supply of Teflon tape and four new valve stem caps--not a big deal, but it does show attention to detail. You will new an air compressor with decent output--I don't think there are very many of the 12v kind that have changeable ¼" NPT output.

Working like advertised

6-4-18: I purchased this along with another manual gauge type in order to make life easier to fill tires. I had a low cost stand alone digital gauge that kept failing. The unit arrived quickly with all the components. I was able to get it up and running quickly based on the feedback from another user: Use LOTS of tape. I believe they did not machine the threads to the correct tolerance so you need a lot of tape to seal the nipple to the inflator. Once sealed correctly it does not leak. I went right out and attached to my tires on my car - and the end leaked on me. I was a bit disappointed. I tried the other inflator on the same tires and it did not leak. I tried on 2 other tires, same result. I contacted the seller and was VERY please when they responded within 1 day and sent out a replacement right away! That one works well. So pros: -Quick, easy read of tire pressure across a wide range (from ATV at 3 psi to Truck tires up to 100+Psi - I do not have 200 psi to test). -Accurate: Mine was spot on with other gauges. I do not have a calibrated pressure gauge to know it's within 0.2 PSI, but good grief I bet you don't either. It was far good enough for what I needed. Someone else will have to review down to that level of accuracy with a calibrated gauge. (NOTE: if other sellers say they compared it to the onscreen or other gauge - I would immediately ask: How do they know that's right too?) -Nice that it comes with everything to assemble and go! a couple extra tools. -Feels robust -Runs on easily replaceable AA batteries -Love the ease and speed for filling and checking. It took me a few minutes to realize this can replace your normal tire gauge too...you don't have to be filling to use it to check pressure - doh... -great customer response! Cons: -Machining on the bottom threads is too big - may be a batch issue. the seal on them requires a lot of the included tape. Not a deal breaker just make sure you tape it up good and check it - if it leaks, take it back out and tape MORE. -Sometimes difficult to get chuck to seal on stem. I sprayed a little WD-40 into the end and blew it back out. That seemed to help lube the seal. Then NOTE: you must push the chuck onto the stem pretty firmly to get it to seal. If you do that it seals and works right. if you do not press very firmly it seems to leak. Maybe a slightly thicker gasket in that chuck would solve the problem. -It feels a little expensive at 3 10 spots. But it is slick so maybe not? - The chuck may not fit onto stems that are recessed into a hub cap or cover. This is common of all these types so not this product specific, but be aware a simple old style filler may be required on those to fit. We shall see on durability! I will update if I have a problem. Just to be clear: I paid the full price on this unit. I left a review because I appreciate the response of the seller and I think it's important to know.

Excellent product and accurate too.

Perfect for knowing what pressure you’re at without having to go to a gas station. I have a 2 gallon pump and now I know exactly what pressure I’m at while filling anything up!

I love this thing. For the $, hard to beat it. I would buy again without hesitation.

This is July of 2026, and still working. I would say it has a large margin for error. You don't get a clear reading till the pressured air stops. It will not ready well, in filling the tire.

Great quality, I used it few times now and its very accurate and easy to use. The price is good too.

Pleasantly surprised, well made, great quality, no leaks, accurate.

Great and solid quality.
