BUY THIS GAUGE; NOT THE ONES ADVERTISING ON TV
After tossing my Woowind due to poor battery life, I tried an Airmoto. What absolute piece of garbage that was. I can't believe I saw a TV commercial for it as its such garbage. In just topping off tires 2-4 psi due to seasonal weather changes, that battery would deplete more than a third after a few minutes of use. The worst part was that once it reached the preset PSI it would keep pumping air for 20 more seconds. That meant all tires were overinflated by at least 1.7-2 PSI each. ABSOLUTE JUNK. Since I passed the return period, that too was binned. Onto the Etenwolf. I took my time reviewing all tire inflators and this one interested me as Etenwolf has an interesting range of tire inflators for various vehicle and tire sizes. This S1 which appears to be a newly listed item at the beginning of 2026 fills my needs. I did ignore all of the vine reviews as I can't take serious a review of a "free product". Since I already just purchased an Etenwolf tire pressure gauge that I was happy with I bought this S1 and I'm glad I did. The Etenwolf destroys the Woowind and Airmoto in function, quality, and durability. The air hose is already attached and longer than the other two that have hoses you need to screw on. The display on the Etenwolf is much more clear to read and understand and the body of the machine has much better button layout than the other two that both had identical multi-function cicle pads. The Eternwolf is the only one of the three that has a chuck you can add to the hose and the chuck is metal; not plastic like I see on other inflators. I'm not a chuck fan, so I won't be using it; however it was nice to be included with other nozzles for balls, bikes, etc. and also be metal. The three best features to me are: 1) the nozzle screw on fitting as unlike the other two that also had nozzle screw on fittings, when I unscrew there is practically no air loss unlike Woowind and Airmoto where if I unscrewed the fitting at any speed other than rapidly fast I would lose a fair amount of air. 2) the accuracy of the inflator's gauge. It matches Etenwolf's tire pressure gauge and both read the same pressure as my car's TMPS sensors. Very accurate. 3) the inflator shuts off the moment it reaches the preset level. The Woowind would go about 5 seconds longer; and the junk Airmoto would go at least 20 seconds beyond. So far I am VERY VERY pleased with the quality and function of the S1 inflator and the included storage bag is big enough that I can also store the Etenwolf T300 tire pressure gauge in it as well.
