AstroAI Digital Tyre Inflator Gauge, 250 PSI, Quick-Connect Chuck

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

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.

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.

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.

I am really impressed with this inflator, especially for the price. As shown in the picture, it thoughtfully comes with several adapters, including a clamp-on adapter, as well as a valve stem tool and a roll of Teflon tape for sealing the threaded connections. It seems to be sturdy, well constructed, and is of a nice size, not some micro-mini, hard to handle or read device. It has a stated accuracy of 1%, which means that at 100 psi the true pressure may be between 99 and 101 psi. This isn’t bad, considering that your tire pressure changes by about 1 psi for every 10 degree F change in temperature. It can be used as a stand-alone pressure gauge (ie, not connected to an air compressor) to read your tire pressure, and it compares favorably (within less than 1 psi) to both another digital pressure gauge and an analog gauge that I have. Like most inflators, you don’t get an accurate tire pressure reading while actively inflating or relieving pressure in the tire. Especially nice and helpful is the pressure relief button on the side, which makes adjusting a higher than spec pressure easy and convenient. The only fault I can find thus far is that it doesn’t have a “hook loop” so that you can hang it or attach a hook to it, although this certainly wouldn’t deter me from purchasing it again.
