AstroAI Digital Tire Pressure Gauge with Inflator, 3-250 PSI Air Chuck & Compressor Accessories Heavy Duty with Quick Connect Coupler, 0.1 Display Resolution, 1pack

Using this several times a week to check and fill mountain bike tires, my motorcycle tires, and our car and truck. Hooked it up to a hose from my mini compressor or my travel air compressor. Connects to Schrader (the one everyone associates with car tires) easily. Not sure why some are having problems. As long as I get the connection properly in line with the valve it slips right on and snaps to connect. I leave the presta valve connector in the valve head so I never have to look for it.Checked mine for accuracy and it was exact every time.PROsExcellent qualityTight connectionIncludes presta valve adapterAccurateCONsNone thus far…and I am not expecting any.Recommendation - definitely recommend for anyone looking to simplify lots of tire pressure checks and adjustments

I’ve owned this tool for 3+ years and it hasn’t broken on me. Easy to use and basic functions. The digital screen helps to know your airing up tires to the correct pressure.

A quality unit, however, the spring loaded securing means for grasping a tire stem works marginally. As likely to discharge air as to envelope the stem for securely adding air. Guage and handle-stem work fine. Had to buy stem-extenders due to cumbersome 'lock mechanism'

I have never had a tire inflater that's actually accurate before.I have always used gauges that have the popup pressure gauge, they were always a little "ball park".Since using this gauge i started noticing that my vehicles that have the tire pressure sensors read exactly the same as the vehicle says.And it's not like it's just one tire, but all of them!I always figured the tire pressure sensors were just "ball park" also.The answer = nope i have been using garbage inflators.Even the little discount tire pressure gauges are off.. lolI now have two of these floating around my garage.And while setting up my Jeep for adventures, i installed onboard air.I spent a bit on the air setup, in the end i was willing to spend the coin on ARB's little manifold since it was perfectly setup for the teraflex compressor mount, but no way was i going to spend over a hundred bucks for their airlines and connectors.So i ended up with standard stuff for the tire inflator function, but i still needed a pressure gauge/air chuck that would lock onto the valve stem.So another one of these fit the bill.I have a bungee cord on standby for the handle part but the main thing is that it locks to the valve stem and doesn't leak.Good stuff!

The gauge is easy to read once turned on. It was very easy to attach into the valve stem, and it stayed attached and sealed. For the money this was a good purchase.

At this price point, there’s issues to be expected. The whole point of a locking inflator is to not have to hold the chuck, which still has to be done on mine or it leaks. Not impressed but for the price I can’t be surprised.Edit: seller contacted me through email and asked for some more details. They sent me another unit and didn’t have any issues with it- locks on, accurate reading, no leaks this time. Very impressed with the seller standing by their product and the value for the money paid once the leaking unit was replaced.

It was delivered in a day, and the digital readout is slick and is accurate to the 10th of a psi.

I rarely have to inflate my tires, however when I do, I usually go to a local tire store. The last time I had to request air inflation, the tire store had a digital tire inflater. It was spot on! I used to be a mechanic YEARS ago, we had nothing like this. I currently needed air in my tires due to whether change. Heat over expandes, cold deflates. I went to Amazon for giggles, found this digital tire inflater, for under $30.00 I was more than satisfied!!! If you are a HOME mechanic, garage wrencher, A+ I highly recommend. By the way I have, and you will need, an air compressor to use.
