ETENWOLF ZEPHYR S3 Tire Inflator Portable Air Compressor, 1 Min Fast Inflation and 100% Duty Cycle, 160 PSI Air Pump for Cars, SUVs, Bikes, Balls (Vivid Orange)

I got this after the one I had died. This thing is great! Compact, easy to use, and has long battery life. Great to just leave in my trunk on road trips and saves me money and time from having to stop at a gas station/rest stop. I have one tire that is a little leaky, so having it in my car at all times helps me get back on the road all the time. The settings are easy to see with the digital display, and the automatic shutoff feature is my favorite, so I can set it and forget it.

I have a bike and a small car. If you have either or both, this compressor is great. My car tires need 33 PSI but were low around 25, so I just pumped them and it took just a few quick minutes and only drained 1 battery bar. Perfect. Bike is 70 PSI, went quickly. Remember to use the quick connection valve for both. If you need more air or got large inflatables, the larger model is twice the size but works the same. I like that this model is smaller.

Super fast and reliable! Inflates car, bike, and ball tires in about a minute. Seems accurate with PSI readings and doesn’t overheat. Comes with a convenient bug, compact and easy to use, and offers great value for money. Highly recommend!

Absolutely outstanding. Simple and easy to use. Press power. Use up and down keys to set the desired PSI, screw into car tire, and press go.

This little thing is simply amazing. No problem pumping up car tires, bicycle tires, blow up rafts. It's rechargable! Charge lasts a looooong time. Being able to use the dial to set your desired pressure, turn it on and it just shuts off when the pressure is completed. Seems very well built. Highly recommend

Arrived partially charged and quickly charged to 100%. Nice, compact and well built. All 4 tires were a little low from sitting. Easy to hook up, select the default for car, press the button and walk away. Automatically shuts off at requested pressure. Inflated all 4 tires to pressure without any issues and plenty of charge left to do more. I'd buy it again. It would make a nice gift. In the summer heat, instructions advise to not store it in the vehicle. I'm okay with that. 6/20/25: SUV's tire pressure warning beeped. We pulled into a parking lot and resolved the issue in less than 5 minutes.

So this is my second Etenwolf compressor. I've also got the big boy, the S6. Don't want this to be a review for that, but it's amazing and certainly influenced my decision to buy this little fella too. The S6 is for my truck, and I've had a little no name Chinese pump for my car for the past couple of years. But, it suddenly died a couple of days ago, and I decided to buy the S3 as a replacement. These things are so well made and there's so much attention to detail and build quality it's insane. It's built like a brick, it has very nice little anti vibration feet on the bottom, a nice built in light, a very nice case, and a clear display with intuitive controls. Battery is good for a couple of top ups on all for tires if you're just doing a sedan/crossover. It inflates way faster than my old pump. It even remembers the PSI setting from the last time it was used, which is a nice little detail. It also has a USB port so you can use it as a power bank in a pinch. It's amazing to me that this thing is pretty much the same price as some of the no name cheap compressors you can find all over Amazon. If you're in the market, get this one.

I bought the smaller version of this tire inflator because I wanted something lightweight, practical, and easy to keep in my trunk without adding extra bulk. It’s perfect for daily commuting, long trips, or just peace of mind. Beyond car tires, it comes with adapters for basketballs, footballs, bikes, and motorcycles, making it very versatile. It charges with a standard Android charger and I always leave it fully charged so it’s ready when needed. This inflator has already saved me a few times. It’s not meant to completely replace a tire shop, but if you get a flat or just need air to reach the nearest shop, this will absolutely get the job done. I especially find it useful in the winter months when tire pressure naturally drops — I just top off my PSI at home instead of wasting time and quarters at a gas station. Keeping your tires at the right pressure also helps with fuel economy and ride comfort, so it pays off in multiple ways. Performance-wise, I give it 5/5: • Very compact and easy to store. • Quickly tops off car tires. • Reliable for emergencies and peace of mind. • Great versatility with included adapters. The only trade-off is the battery life, which isn’t very long due to the smaller size. Filling all four tires up to ~35–38 PSI will already drop the battery a bar or two, and if you’re filling multiple vehicles it drains even faster. If you want longer runtime, the larger version is a better option — but for practicality and portability, this smaller one is perfect. Bottom line: For the price, convenience, and reliability, this is one of the best safety items you can keep in your car. It won’t replace professional equipment, but it will definitely get you out of a pinch. Highly recommended.

Unlike the majority of inflators listed, the Etenwolf is manufactured to provide accurate results. As tyre pressure accuracy and consistency is a central safety consideration, I would suggest calibration would be the primary design criteria. In achieving internationally recognised calibration standards, Etenwoolf have not however compromised on useful features including a low pressure inflator and multi-function torch. The compact size, cordless design and useful battery life contribute to its ease of use. Well worth the extra cost for a fit-for-purpose product.

Used it on a few SUV tires and its does a pretty good job..Takes about 5 minutes from a complete flat to around 50 psi.Runs a tad warm and not too noisy. Its better to let it cool down a bit after each tire though.Time will tell how long it last but first impressions it does it job and small enough to leave inside a trunk.

El equipo está super bonito, muy bien diseñado e infla rápido las llantas, el problema es que no infla tantas llantas como dice, por ejemplo, fue probado en un mini cooper, y se les aplico a 3 llantas 15 psi más o menos (de 20 a 35 psi) y 1 se lleno desde 0, ya con eso solo quedo una rayita de 4 de carga del equipo (esto fue durante el primer uso y tras haberlo cargado al máximo), así que es muy fácil de transportar (es minúsculo), ligero y muy bonito, pero para inflar todas las llantas desde 0 no alcanza, es más que nada para una emergencia.

Excellent product

I RARELY write reviews, but felt compelled to really share my experience with this AMAZING inflator. I am EXTREMELY IMPRESSED!!!❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️ It exceeded all expectations. Why: 1. Have tried several brands; this one stands out as the best by far. 2. Simple and intuitive to operate—did not need to consult the manual. 3. Gas stations charge $2 for every 2 minutes of air, making it expensive to fill all four tires. 4. This pump offers significant savings and convenience compared to using gas station air. 5. Efficiently inflates all four tires without hassle. 6. It comes with a carry-on bag which is super convenient. I place latex gloves inside, so my hands don't get dirty when I am inflating my tires. 7. I love how it stops when you set it at the desired PSI. 8. It's super FAST! 9. The hose is long enough, unlike other brands where you have to physically hold it in your hand if it doesn't reach. 10. Liked it so much, I purchased a second unit as a gift for my dad.
