AstroAI Digital Tyre Inflator Gauge, 250 PSI, Quick-Connect Chuck | Backlit display with 4 pressure units, hose and bleed valve; fits 1/4in NPT compressors for cars, SUVs, trucks, motorcycles

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

Great Quality great price

This tyre inflator is good value, easy to use, accurate and appears well made. The only minor criticism is that it can be a little tricky to seal over floppy valves stems (rigid valve stems are fine) - but once sealed it works well. The illuminated display is a nice feature and it's a doddle to change between PSI, Kg/cm², bar and KPA. I have a decent digital pressure gauge that I always used with my previous inflators, as the readings they gave were always way out, but this one negates the need for double checking - so making the whole process much quicker and easier

Excellent product

Appears to be accurate for inflation tyres at home when compared to another gauge. It has a large digital display that is more than bright enough for working in the dark or back of the garage. The lever is a paddle type so kind of binary off/on until you’re used to it, although this has no bearing for its intended use. Be aware the inflation connector has a small lever to grip your tyre valve thread. You need to depress the connector lever to insert/remove the tool. I also use this inflation tool in-line with a bicycle Presta connector from a track pump to seat tubeless tyres. Works a treat is you already own an air compressor.

I have had many days with my tyres not at full pressure. I have got to use a standard foot pump which takes forever and when it is disconnected , some of the pressure is lost. I saw this pump which plugs in to a compressor, and only takes 30 seconds to pump all four tyres to the correct PSI at only £23.00. I had to have it. even only using it the once ,proved to me it was worth it. not having to stand out in the rain for 20 minutes was perfect. i then went around the house, inflating all the kids bikes, so easy. I wish I had bought one years ago.

It works

It's incredibly accurate! I inflated the tyres to the manufacturer recommended level, and then checked them with a different pressure gauge, as well as my vehicle's smart monitoring system, and the pressure was 100% accurate. Build quality is excellent. The only small complaint I have is that the clip on the valve coupling doesn't hold onto the valve stem properly, and I'd have preferred it to just not be there at all since you need to press it up into the tyre valve manually to prevent leakage. I am comfortable recommending this product though since it is extremely accurate.

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

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.
