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

Fantastic product! First off you do need an air compressor to use this. The compressor I have came with a standard set of tire filler attachments. I replaced the current car tire filler with the new AstroAI Digital Tire inflator and used it to top off the tires on both our cars. What a change!! Previously I would put in some air into the tire, then detach, hook up an air pressure gage to see what the new pressure was, then put more air in, repeat, repeat, repeat. Now with the AstroAI inflator I can see the tire pressure once I stop filling the tire without detaching. The spring-loaded catch on the tire connector works great. It holds the filler onto the tire stem so you don't have to constantly push the filler against the tire stem. It also connects much easier with virtually no air loss from the tire (unlike the old filler). The on-off air pressure filler switch also works great for adding and stopping putting air into your tire from the compressor. In order to get an accurate tire pressure you need to stop adding air, which is very easy with the on-off handle switch. During air addition to the tire the pressure reads high due to the higher pressure of the air coming in from the compressor. The air release button also works great. Filling tires is now 10 times easier, quicker, and far more accurate with this system. I used it on my bicycle as well. Previously due to the higher pressure needed for bike tires it was VERY difficult to engage the old filler onto the stem. I actually had to use a pair of pliers to hold the stem in order to push hard enough to put air into the tire. What a pain. The new AstroAI filler also works great here as well. While the spring locking catch didn't fully engage on my bike tire stem (the threaded section wasn't long enough), it still worked much better than the old system. Same advantages as outlined above for filling a car tire. I'm extremely impressed and happy with this device. 5 stars all the way.

Pretty decent air chuck. Was surprised at how much I have used it and its working great. Definitely a good buy.

After using the Astro AI Inflator I came away impressed. I read so much about the lock mechanisms being cheap and breaking but I did not feel that way after looking at it closely. Seem strong and would hold up. It simply a spring-loaded bar that uses the tire valves thread to hold it in place. If one wiggles it back and forth air will leak but one can always find the sweet spot that seals and allows one-handed operation. A nice feature is that it turns on as soon as pressure is detected so you don't have to manually turn it on. It also turns itself off after an idle period to save batteries. The accuracy was good although it read 1-2 lb PSI more than 2 other gauges I have but well within any reasonable tolerance. The display is easy to read with large characters and especially since it has a backlit display. The backlight is very handy on a dark night without any other light as it provides enough light to illuminate the tire and find the valve. I've provided a picture of the night illumination when I actually needed to inflate the tire without other light. It comes with batteries and these are AAA and easily accessed. It's a real treat to have a pressure release button right on the unit but if you want to release air fast it would be better just to depress the valve stem directly. There is no small protrusion on the unit to facilitate manual air release.

You have to do the final assembly of the Schroeder valve chuck, and the Milton M type air hose fitting. They provide the teflon tape in the box. I had zero leaks from the Schroeder valve chuck when clipped on a tire valve stem, the brass chuck appears to be of good quality. Same no leaks from the hose coupling fitting, when coupled with a Milton brand quick hose coupler. I give this 4 stars as it restricts the air flow while filling a tire (much more then my old Milton air chuck). I filled the four .5 ton pickup tires from 25PSI to 35PSI, and it took about a minute per tire to increase the pressure 10PSI. When you depress the fill lever, the gauge reading goes to zero, so you have to release it to get a measurement. I don't have any current means to check the accuracy of the pressure gauge. The .1PSI resolution is really overkill. But it does droop about .5PSI over a 20 second period, and the reading is repeatable when I unchuck and rechuck the Schroeder connector. The gauge turns on automatically when it senses a pressure on the hose outlet. The instructions don't say anything about completing the assembly with the hose fittings and teflon tape, which is what I assume the negative 1 star reviews were complaining about, as the fittings came finger tight from the factory. Completing the assembly, the Milton type male air fitting used a 5/8 flat wrench which was very tight. The Schroeder chuck required a 14mm wrench. I used a bench vice to hold the hose and body of the inflator, so I can't reference a flat wrench for assembly. The slow fill is probably real good for bike tires, and maybe the design intent, as it came with an European valve stem adapter. I am happy with this, as I also have bike tires to maintain, and overfilling is very easy with the Milton S-506. I'll update this review if I have any issues in the future.

Purchased this for my husband as a gift and he said it works great.

Awesome product and super easy to use! Makes airing up any tires a breeze! It’s sturdy, and seems to be built with good quality in mind!

My review of this product has two very different levels, and both deserve all five stars. Note first that I am NOT an official "reviewer" for Amazon, and I did not receive the item free or for reduced price. I just bought it because it looked like it would be good, and I was extremely satisfied after the small issue that has since been resolved nicely (see below). First: The gauge and its supplementary parts: Other than the aforementioned small issue, this by far the best tire inflator system I have ever used. I have used many of these over my more-than-five-decades of working on vehicles. This is the easiest to use system, is extremely-accurate, and requires the least effort. It provides several measuring system (like lbs/ kpa, etc.), provides a backlighted display, and is super-easy to use. Even securing the thing to the tire stem is extra-easy, and it remains attached until you deliberately release it. I wish I had bought this thing years ago. It is worth every penny. I did have a small issue with the product in that it had a very tiny air leak right at the chuck. Originally, I though that the leak was so small that I wouldn't even mention it, but I decided to ask the vendor about it. When I communicated with the company, and they agreed to replace it immediately. No hassle. Fantastic attitude. Like business was conducted decades ago when almost everyone was honest and wanted to assist the customer. As you can see, I am impressed with both the tire equipment and the vendor. Do not nesitate to do business with them. Again: I have no vested interest here and was not paid or asked to do this review.

Good quality product. I frequently used in rugged conditions to deflate during my desert drives with F150.

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

جهاز قياس ضغط ممتاز ويعتبر توصيلة هواء ايضا .. يعني 2 في 1

Class. Works well and the pressure shows up quickly and gets calibrated at my place of work just fine. Would buy again
