Easy to use!
Great little air compressor. I've used it on my car and small tractor and it did the job. Easy to use too. Just set the pressure you need and it stops when the desired pressure is reached.
Brek Jennings
Nice unit
I luv this compressor and will inflate a 17 inch flat tire in about 15 - 20 minutes to 35 psi. Very good quality and fast. Easy to use and has a nice bag it goes in to hold everything and storage.
Andrew B
Works as advertised
This unit seems well built. I topped up all 4 midsize tires and still had battery charge left. Comes in a nice case, and adapter fittings are on the unit. LED work light is nice to have. I would recommend.

Worked so well, I ordered 2 more!
Fantastic unit! Great function, case and accessories. It was already charged upon receipt. I topped off 3 vehicles and 2 bicycles with half charge still left. It worked so well that I ordered one 2 more just like the first.
Franz
This is the one to get
This little pump is truly amazing. Worth it. Compact, it easily inflates all four tires from 25 to 36 psi. The valve lock works perfectly, even on short stems. I love the set it and forget PSI. USBC chargeable! I also like the settings for sports equipment vs. tires vs. bicycles. Get it!
Allan M
Works great
I love this inflator and use it all the time to monitor and maintain our vehicle tires, bike tires, etc.No need to plug in while using and rechargeable which makes it super convenient. Noise level is not super loud so no issues there. Definitely would buy again and may give as a gift!

Frequently Asked Questions
What is a digital tire pump?
A digital tire pump is an automated, electric device that inflates tires using a digital interface to set and monitor the desired pressure. Unlike traditional gas station pumps, which require manual adjustments and monitoring, a digital tire pump offers preset modes, automatic shut-off, and accurate pressure readings. It is typically powered by a rechargeable battery or a car’s 12V outlet, providing convenience, portability, and precision for easy tire inflation at home or on the go.
How long does Zephyr S3 tire inflator take to reach a full charge?
It takes around 1 hours to fully charge with a USB-C 30W fast charging port. Suitable for any A to C or C to C charger, you can easily power the device without needing specialized cables.
Can the ETENWOLF Zephyr S3 be used for inflating bike tires?
Yes! The Zephyr S3 includes preset modes specifically designed for bike tires, ensuring quick and easy inflation for cyclists. Moreover, it comes with presta valve adapter, ensuring wide compatibility with bikes, from mountain bikes to road bikes.
Is it safe to inflate a punctured tire?
While it may temporarily restore pressure, it doesn't address the underlying issue, and the tire can quickly lose air again. If the puncture is large or in a critical area, inflating the tire could cause further damage or even lead to a dangerous blowout. Additionally, uneven pressure distribution can lead to irregular wear and affect vehicle handling, increasing the risk of a loss of control. It's best to properly repair the tire or replace it to ensure safety.
What if i put too much air in my tire?
Over-inflating your tire can be dangerous as it increases the risk of a blowout, reduces the tire's grip on the road, and leads to uneven wear. To prevent this, the Zephyr S3 tire inflator offers 4 preset modes and an automatic shut-off feature that ensures you never over-inflate. And the Zephyr S3 is equipped with a deflate function, allowing you to release air from your tire to adjust the pressure to the desired level for for specific driving conditions, like off-road or sports activities.
