Astro Pneumatic (AST3018) 3.5" Digital Tire Inflator with Hose

Priced out an air chuck with Strap-On... I mean Snap-On Mac Tools and Matco and they all wanted over 250 dollars for basically this exact air chuck! No thanks! I will gladly use this one! Great product for over half the price! Has the protective rubber around the digital meter and everything! Truly an amazing air digital air chuck for the price! Would recommend this to anyone who needs one over anything else all day!

The product is very well made and feels like a high quality item in hands.I'd give this 4.5 starsI haven't been able to verify accuracy of psi meter but don't doubt that it should be accurate. To me accuracy is also repeatability, where even if the actual psi is off, at least that it stays consistent for all wheels.With the various other devices I'd pump it to 34psi, then remeasure same tire right away and it's reading 31psi, remeasure it'll read 32, etc. that's the worst thing that can happen because you don't know what next wheel is pumped to. With the astro, at least if you pumped to 34, it'll read 34 on successive attempts to verify.Negatives:This device seems like it was designed 20 or more years ago and not up to date on current things.Although I don't use it often, seems like eats batteries WAY too fast. Why not use readily available AA batteries instead, or even single rechargeable 1850 ? Or why not just redesign whole thing to just have whole thing be rechargeable from usb-c port, like it's becoming common on devices. If someone keeps this in trunk and batteries die, like they do in the cold climate, most people have 5volt power bricks or USB charging ports in cars that they should be able to use it to power it up.I don't remember ever using device with aaa batteries where battery life wasn't horrible. On a professional product such as astro, using AAA batteries is almost inexcusable.Battery life is the one big negative about this, also changing batteries could/ should have been designed to be much easier to do rather than its done now which is super annoying trying to peel back the cover.I keep this thing in garage and in winter the cover is hard to stretch to change batteries.The buttons on this are not laid out with any sort of reason or thinking.When using this device in the cold with gloves it's hard to press buttons spaced so close together. They should have been spaced at least thumb width apart.Regardless of above annoyances, I appreciate solid build and seems like it's accurate but it needs thoughtful redesign to bring it into 21st century, given its price

This is by far the best air inflator gauge I’ve ever used it’s accurate it lights up good the handle to inflate and deflate works great and the chuck locks on the valve stem really good my milton isn’t half this good and I payed more for the Milton. Great product I would definitely buy more of there products

I work in a smaller shop with two other techs and out of all the tools I've purchased, this is one of the few I've had absolutely no issues with. To start, the build quality is very sturdy, with brass fittings and a stainless steel braided hose. Moreover, the strainless hose includes a rubber strain relief where the hose exits the tool. Even after months of heavy usage and getting tossed around, the hose shows no signs of wear at all.As far as air chucks go, it's the most comfortable and intuitive I've ever used. The smooth, yet sturdy steel lever is dual purpose. The first 50% of travel will release air. Squeeze it fully and it will start adding air to whatever it's connected to. In my opinion, this is far more comfortable than the vast majority of analog air chucks, which require you to tilt the air fitting off to the side to release air from the schrader valve. The locking chuck is a nice touch, but depending on the condition of the valve stem, it may or may not seal without some extra down-pressure on the fitting. This is less a problem with the chuck and more a problem with worn, dirty or low quality valve stems on tires. In day-to-day usage it's a non-issue for me.The single button powers on the tool with one press. Press it again and it will turn on the back light. Hold the button and it will switch measurement units (PSI, KG and BAR). The back light does not stay on for very long (15 - 20 seconds), but this is okay as our shop is on the darker side, and I still have no trouble reading the display, even with all the bay doors shut. The back light is there just in case you're airing something up in the dark and need some extra light. It's not something you'll use all the time. It helps a lot with battery life. On average, I use this chuck about 20 times a day, 5 days out of the week and I'm averaging about 1 - 2 months on the 2 AAA batteries. In my opinion, this is excellent battery life. Just keep in mind this tool will give you no warning when the batteries are low. It will simply shut off completely and not power back on. There seems to be no difference in accuracy, regardless of the battery life.As far as accuracy goes, this tool is right up there with the best of them. I frequently air up tires on Alfa Romeos which have sensors that report pressures to the nearest 10th of a PSI. Airing them up to factory specs, I find the sensors to always report within 1 - 2/10ths of a PSI to the pressure I set. And this across 100+ different cars on different days with different sensors. This is excellent and great for picky customers that demand their tire pressures be exact across all four tires. Good luck trying to achieve this accuracy with an old-school Milton tire inflator. And if you're worried about this gauge taking a while to update the reading, worry no more. As soon as I release the trigger to check the pressure, it updates the reading within 1/4 of a second. Awesome.In spite of my glowing review, I do see some areas that could be improved in a later version. First of all, the hanging loop built into the rubber boot that fits around the tool is starting to show very slight tearing (I always hang it from a re-purposed coat hanger on the side of my lift. I would prefer a hard hanger molded into the body of the tool for better longevity. Second, it would be nice to have a mode where the backlight turns on as soon as the trigger is pressed (like some digital gauges from Mac). Lastly, there could be more contrast in the display itself. With the back light on, the reading looks somewhat ghostly and not as clear as you would hope. Again, it hasn't been a real problem in my usage, but those with worse eyesight would definitely appreciate more contrast.TL;DR: This unit from Astro absolutely dumpsters gauges even twice the price in overall comfort, quality, accuracy and reliability. If any of you air up tires very often, and you're still using an analog gauge, I strongly urge you to give this inflator a try. After getting used to this gauge, trying to read an analog gauge is like going back to the stone age. You will not be disappointed.Lastly, if I have any problems with this tool, I will update my review. If there are no updates, then you know it's still working perfect.

Just received my order of the Astro Pneumatic Tool 3018 3.5" Digital Tire Inflator with Hose. Easy to set up and connect to a mail air hose connector.I've got a Kobalt digital tire pressure gauge that I prefer to use with my vehicle. I wanted to check to see if there was any difference between that and the Astro unit, and compare that with the tire pressure reading coming in from the TPMS (Tire Pressure Monitoring System) units in the tires. Checking the TPMS readings in the car, then taking a reading with both the Kobalt and the Astro units, I found that the TMPS readings in the car were 29 PSI for each tire, and a reading from both the Astro and the Kobalt showed a tire pressure of 30 PSI. I did this to get an idea of the difference between the TPMS units and the pressure gauges so that I would have an idea of what pressure to observe on the Astro inflator to achieve the closest reading that I prefer for pressure in the tires. NOTE: I'm not sure exactly what the difference is caused by, but since both the tire pressure gauge and the Astro Inflator both showed the same, I'd take the guess and believe that the TPMS units are 1 PSI below the gauges, and will base my inflation pressure +1 PSI greater than the desired pressure. I normally run about 35 PSI.Using the +1 PSI differential, I inflated each tire to 36.1 PSI (I couldn't get it right at 36 PSI, it would jump from 36.1 to 35.9, even with lightly deflating the tires with inflator's deflation mode - lightly squeezing the control handle). I did check each tire's pressure after filling it against the vehicles tire pressure display - it doesn't display in tenths, but after filling each tire to 36.1, the display showed each tire at 35 PSI. So, I'm very pleased with that!Following the instructions to open the battery compartment, it took me a bit to peel back the protective rubber outer cover. It takes a bit of getting used to how to do it, as the rubber is not that flexible, but it does peel back. Definitely do need 2 hands to get it back and hold it.So, at this point, I've only used it one time and I'm happy that I ordered this. It appears that one can purchase replacement parts, which is nice. And looking at reviews for the different digital air inflators, it seemed that the cheaper prices don't always justify buying those inflators - the term 'you get what you pay for' applies.I'll update this review as I continue to use the Astro Pneumatic Tool 3018 3.5" Digital Tire Inflator with Hose. I've got a lot of items that I will be using it on, and see how it lasts and if it maintains it's accuracy over time.But - after initial use, I am very pleased with the Astro Pneumatic Tool 3018 3.5" Digital Tire Inflator with Hose!
