Great product!
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.

Compact, Reliable, and Perfect for Emergencies – A Must-Have in the Trunk
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 DR0Ps – 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 DR0P 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.

Amazing!
Inflated eight tires from 28psi to 35psi in around two minutes each. Unit did not get hot. Only used around 60-65% of charge. Very powerful LED light. Checked tire readings inside my two cars after the inflations and all eight readings were at 35psi. Could sit on a chair while using; much easier on back and knees. The preset at 35psi and the auto shutoff are great features. Pressure hose stores nicely and is of very adequate length. Pressure hose connects quickly and securely to tire stem. Totally clear and understandable instruction book — a rarity these days. Great compact carrying case. Item arrive packed very carefully and securely. When one is unwrapping it, you immediately get the idea that the company cares about giving you a quality product and a very good experience. No need to go to service station and pay to use fickle, expensive air hoses. One of the most useful and high-quality products this 83-year-old has ever bought!

A wonderful piece of gear!
This thing is just great. First, each unit comes with a calibration certificate so you know that not only are the pressure readings within tolerance, the speed of inflation is as well. It is just remarkably easy to use. The hose snaps onto the tire valve, turn it on and read the pressure. If it is high, bleed it out by pressing a button. If it is low, press another button and it will inflate precisely to your preset pressure. Unlike many portable inflators, this one is fast and it is not overly noisy. Highly recommended!

Great battery operated air compressor, This one can easily travel with you .
Super air compressor that is battery operated which increases its capabilities. There are many battery operated air compressors but there aren’t that many good or better battery operated air compressors. This is one of the great battery operated air compressors that will do everything that you need from a small air compressor. Highly recommend it.

Fast and Quiet
This is a pretty good pump. I like how you can adjust the the air pressure in incriments so that you get more accurate air pressure. It also has an air pressure release valve on it to let the air out. It’s wireless so it’s easy to move around. It doesn’t take long to fill up the tires and it’s quieter than other air pumps that I have tried. I can put air in all four tires before it needs charging. The stem they use to attach the pump to tires is metal so it’s less likely to break. I just wander how long the pump itself will last.

Compact, very nice package
This compact air compressor is super cool. Love the size, love the carry bag, plus the USB charging connector, and the bright 4-way light. My needs for something like this are for things like rafts, beach balls, blow up mattresses, or paddle boards. I tested this out on a beach ball and a raft. 14″ Beach ball: filled in 2 minutes on 30psi 48″ x 38″ raft: started at full charge – filled the “floor ribs” in 4 minutes at 50psi – filled the body in 13 minutes with two different powers: 6 minutes at 96psi, and the machine timed out with an E15 code because it had run so long. It started right back up though. Since it was going so slow, I turned up the power to the max at 160psi and finished the job in 7 more minutes. There were 2 bars left on the battery after filling the raft. This unit has the attachment nozzles on board the unit, and the hose winds up neatly on the back. It also comes with charging cable and an air chuck, whatever that is. I used to lug around a comparatively huge and LOUD electric compressor on camping trips. This is much easier to pack and gets the job done, even though it takes a little longer. It’s especially a good choice if you can have it plugged into power if you have more things to blow up. Nice unit and I recommend it.

50%off this is 40$ with tax and I have 300$and expensive 1s that aren’t as easy to use as this 1
Great Deal I purchased this 1 for the wife or Ford Escape Titanium was hit a few weeks ago and not going to be repaired until April we have roadside tires are under warranty but a back tire keeps loosing air and needs to be replaced by the insurance at only 30$ and tax this is a must have for anyone who owns a car I have a 400gl IR compressor for the work I do but 2$ for air at any gas station around the garages usely help out but we live 5 miles to the closest. I now have peice of mind for my Disabled stage 4 type 1 diabetic wife and it charges off same cord as our phones and her medical equipment and is a battery bank as well it will be well used this spring and summer time for the bycylces Floats rafts and camping season

What a cute air pump! Works Great!
This little thing has some power behind it. It has different attachments for tires to floats. It is very easy to use. I like that you set the function and it automatically tells you when your tires have reached the optimum pressure. No guessing. The carrying bag is adorable. This fits in the car great without getting in the way.

My third and final. Gave the other two away.
This is my third compressor/inflator in this price range and by far the best! It makes much less noise and is stabilized by two large flexible rubber pads. It doesn’t vibrate around on the floor. It’s compact so packs easily away. It worked great on my car (I wondered if the car might be too heavy), and today I used it to inflate a flat tire on my lawn tractor. I didn’t even bother to read the directions: 1. I attached the hose. 2. Pressed the power button. 3. Using the “+/-” symbols, I set the desired pressure. 4. Pressed the power button again. It inflated the tire and shut off automatically. It has stored the charge since I purchased it four months ago. The brass and steel snap attachment to the valve stem is much easier than trying to match threads and screw it on. As you can see in the photo, it has a button that will release air pressure if needed.

Incredible is an understatement
Seriously, to say this little portable air compressor is incredible is a total understatement. Words don’t do it justice. I have been a fan of portable air compressors, but they tend to have their limitations – be it hose length or sheer power. This one overcomes most of them. The design is thoughtful and useful. They considered both form AND function with this device. I love how it stores the extra parts onboard in the back, and the hose can actually reach the top of the car tire without the unit “hanging” loosely as many others do. It’s very easy to read and I found that the battery lasts a while. I topped off all 4 of my truck tires to 35psi cold today (was at about 31 psi), and it used only 1 bar of 4 on the battery. I don’t think it will fully fill 4 car tires from scratch, but I do think it will do at least 1-2, and it will do about 95% of what you need it to do. The durable and practical storage case with handle and the light are nice bonuses. This feels totally durable and I really feel this is a lifetime purchase, unlike many others I’ve seen. Don’t even think about others, just get this one!

Lightweight and very portable. I was a little skeptical about this being able to blow up the tires on my car since I’m used to a pretty stout tank compressor, but so far, it works great. Built in pressure control, which is great.

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.

Just tried it ,works perfect.Inflates quickly and a feature that no one probably mentions is when it gets close to the desired number the unit slows down then stops at the preset mark .I bought the air moto and this beats it hands down.Its much much faster .The battery life is way better and it’s cheaper.The battery life on the airmoto for car tire inflation is no good .You definitely won’t get two tires done before the battery goes red
