The air compressor’s “Auto Shut Off” functionality ensures safety by automatically halting inflation when the target pressure is reached, safeguarding against overinflation. A clear and user-friendly digital gauge provides accuracy within +/- 1 PSI and offers four unit display options (BAR, KPA, PSI, KG/CM2) for versatile use in various inflation scenarios, ensuring reliable air pressure monitoring every time.
- Benefit from dual power flexibility: The ST189CD tire inflator offers a dependable dual power system for your convenience.

The 20V cordless air compressor blends power and convenience, making it a reliable tool for inflating tires and more.

Tire inflation is as simple as pulling a trigger, with a mid-size tire like 195/65R15 inflating in just four minutes. The device includes an intuitive knob system, allowing users to set their desired air pressure quickly, far more straightforward than painstaking button presses. Once the target pressure is reached, the compressor automatically shuts off, removing the risk of overinflation. Additionally, it supports four pressure units (BAR, KPA, PSI, KG/CM2), making it versatile for different needs.
Designed with multi-functionality in mind, the air compressor features a 20V battery that doubles as an emergency power supply. Equipped with a USB interface, it can recharge mobile devices when needed. What’s more, the compressor includes a built-in LED light, illuminating your workspace at night, during dusk, or in poorly lit areas—ideal for unexpected roadside repairs. For continued use, a 9.8ft 12V DC cigarette lighter power adapter ensures you can connect it to your car’s power source. The long cord offers flexibility, while extra conveniences like a spare fuse add reassurance for everyday users.
This smart and efficient compressor is a perfect addition to any vehicle emergency kit. Its combination of ease of use, portability, and thoughtful features makes it a practical and reliable choice for drivers and homeowners alike.

Opinions about this product were divided in such a proportion among the buyers.
My mini portable inflator quit. I really like this tire inflator. Very easy to use and feel like with the dual power sources it will be ready in any situation that comes up. Comfortable to handle and use. Not complicated, lightweight, work light, can charge phone in emergency, with its own case for storage. I used on a bike that I am selling. Manual states 20 min continuous use, but it took maybe 10 seconds to fill and auto-stopped when at the right pressure. I should not need this very often, but glad to have ready. Switching power sources is as simple as changing the battery. The car adapter is built into a base that clicks in just like the battery. Great Design. Feels well made, sturdy and worry free. I am impressed and would recommend.
I replaced my broken pump from another company but looks similar. I was disappointed that the battery cannot be charged while it is connected to the pump. My old one allowed charging to occur so it was always plugged in when not in use. This would require extra steps that can be forgotten by teenage users and make Dad users upset.

Ask & Know: Your Questions Answered
How long does it take to fully inflate a standard car tire?This portable air compressor can fill a standard car tire (195/65R15) in approximately 4 minutes. The powerful 20V battery ensures quick and efficient inflation, perfect for on-the-go use.
Can it be used for something other than car tires?Yes, absolutely! The air pump comes with six nozzles, making it versatile enough to inflate bike tires, motorcycle tires, sports balls, and even balloons. It’s a great all-around tool to have at home or on the road.

How does the battery life hold up, and can I use it while it’s charging?The 20V lithium-ion battery provides sufficient power for multiple uses on a single charge. If the battery depletes, you also have the option to use the included 12V car adapter to power the inflator directly from your vehicle. While the battery charges fully in just one hour, the pump cannot be used while the battery is actively charging.
Is the air compressor heavy or difficult to carry around?Not at all! Weighing just 3.36 pounds and designed for portability, this handheld pump is easy to carry and use anywhere. It also comes with a convenient tool bag for storage and transport.
Can it work at night or in low-light environments?Yes, it’s perfect for nighttime use! The built-in LED light illuminates the working area, ensuring you can safely and easily inflate your tires or other items even in poor lighting conditions.
Does it work with all car models?This air inflator is compatible with most car models since it supports multiple units of measurement (BAR, PSI, KPA, KG/CM²) and allows you to set pressure levels according to your vehicle’s requirements. The included power cord also ensures it can reach all tires on a standard vehicle with ease.

Snow Blower Fix
The media could not be loaded. Item works as described, turn on, set pressure, let it work, auto shut off at desired psi, used gauge to verify accuracy. Snow blower always has a flat, great fix for the 3x I need it. Tire was flat, inflator ran less than 2 minutes, Trouble finding inner tubes.
joepal –
Highly recommend.
What a fantastic little piece of machinery. Compact, sleek, plenty of accessories and lots of setting options.
Rich –
Easy and compact. Set and walk away.
This tire inflator works really well to top off tires that are a little bit low. I love that I can set the pressure to a desired PSI click the button and it pumps the tire up and shuts off when desired pressure is reached. The gauge on this tire inflator is a few PSI off from my high-end Tire gauges so set PSI on the tire inflator accordingly.

Portability
I saw one of these advertised on TV and liked the concept of a more portable air pump. I have a larger one that serves me well but having to tote it from car to car, trailer to riding mower, etc can get a bit cumbersome. I ordered one without mentioning it to my wife and the day after it arrived she informed me her the tires on her truck needed air. Perfect timing! Perfect opportunity to test out my new gadget! Well, it worked just fine. Small, portable, and efficient. It did the trick! All four tires were a bit low with one of them significantly in need of air and it did just fine with plenty of charge left over. One other thing that pleased me was just how quiet it is compared to my larger compressor. Yep, it worked so well I purchased a second pump, one to keep in each of our vehicles should we, or someone else, have need of it. Only caveat is I wanted the green one but it was twice the price so settled for a different color. Regardless I enthusiastically give it a 5-star rating!

Easy to use
I love that it’s it bulky and so it’s easy to store. It’s great not having cords to deal with! It works great and is easy to use!
Bob Brown –
works well
works better than expected…. makes quick work of raising air pressure in full size pickup tires the auto shutoff is a nice feature
Ron Ho –
Terrific Product
The portable Air Compressor is a terrific buy. It performs as advertised and has come in quite handy. I would recommend this product highly. Great for emergencies, etc.
Russell –
Junk
Smokes a lot and smells like there’s fire inside on it doesn’t air tire up all the way without smoking and shutting down and now it doesn’t work at all
J.F. –
Can’t use on wet surfaces!
I plugged this into my car charger and it didn’t do anything. I didn’t want to try to charge the battery because the instructions says NOT TO USE ON WET SURFACES, etc. How is that possible if you live in a rainy or snowy area? Duh! It’s best to put the money into a more expensive device such as a compressor you charge for a few minutes and use. Plus, if you place the battery somewhere too hot or too cold, you could be in trouble (explosion) Be wise!

Portable tire inflator
Works like a charm and very easy to handle. Was able to help a neighbor out the first day we got it (& she was impressed).
Dee Smith –
A must have
Love this, it so easy to use and carry along for travel use high recommend
cliff –
So convenient
Game changer. No more pulling out the air compressor and running it until the tank gets fully pressurized. Just attach coupling to the tire and pull the trigger. It shuts off when desired pressure is reached. Love it!
Amy Taylor –
Used once and it won’t turn on now.
I gave this as a gift to my dad for Christmas. He used it once and it won’t work anymore. Return window closed a few weeks after I purchased it. Didn’t need to use it until now and it doesn’t work. Would not recommend.
James M. –
Great
I really love it I’ve used it for my tires on my truck and for the basketballs I have it’s perfect.

Don’t waste your money
Used it twice. It started smoking and quit working.
Amazon Customer –
Easy to use
Bought as a gift but they enjoyed it and it was easy to use.
Mike –
Very Hot Air
It worked great until it didn’t. It overheated, smoke came pouring out from it, no doubt it would have flamed up if I hadn’t caught it.
Dave –
It works
I needed something that works and it is convenient and easy.
Keilah Garcia –
Totally worth it!
Easy to use. Easy to store in the trunk of your car. Totally recommend.
Ariana –
A lifesaver!
This works really fast and the battery is great and lasts for all 4 tires! The cold made my tires all REALLY low, like at 15 psi. This aired up all of them in no time on one charge with extra.

Cheap Trash, Returning
Note sure what to think of the other reviews. My experience was horrible. I didn’t buy this to inflate my car tires from flat to full. I bought it to top them off when they were down a few PSI. Just tried them on my small Honda Element tires. Each was down by 3-4 PSI. First one actually was OK. Took about 2 minutes. On the second one, after about 2 minutes it started to smoke and smell. Shut it off. Directions contradict themselves. One part says only designed for 5 mi Ute run time. Another section says 15 minutes of use and to let it cool down 5 minutes. Also said “a little smoke is normal as it is motor lubricant burning off, but to cool it down when it does smoke”. Hmmm. Ok I’ll let it cool off for 10 minutes. I could not after that point for more than a minute before it started smoking again. Literally took 30 minutes for me to do the last 2.5 tires due to the cool down time. On the last one I am pretty sure it fried as it shut off by itself before reaching the set PSI. Battery still had one bar of juice. I will be returning this junk for a traditional plug in compressor. I know it will Cost more and I wanted to avoid an extension cord out to cars, but better than going to gas station and dealing with that trash. I suspected the battery powered, compact promise of this was too good to be true.

Excellent!!
I love it, easy to handle and helpful

TIRE PRESSURE PUMP: Being a woman, I love how light it is!
So convenient to use. Due to fluctuation of temperatures, I was forever losing tire pressure and having to use a service station to inflate my tires.

This is my best investment
After looking at several, including the viral products from TikTok.. I decided to research and give this one a go. I am so pleased that I did! I have a 2008 Ford escape. I have had low tires & often I’m without a gauge and when I pull up at gas stations the air machines are out of order. My ex had a similar type of product, I wanted one too. I used this the 1st time today & it was so easy to use. It took minutes to inflate all of my tires. It comes with a built in gauge and auto shut off. It stores very well, it’s not a bulky product. Works so well I’m highly satisfied & impressed! I’d definitely buy this as a gift. I’m just a girl who doesn’t know squat about cars, but I don’t like relying on others for help.. this saves me from creeps at the gas station & from ruining my tires.
Mark J. –
Great pump!
Works as advertised. Both methods of power work well. It’s lightweight, but powerful for its size. Creates an airtight seal with the valve.
very pleased with this purchase –
loved it!
Works great, great price!
Barry W. Walsh –
Easy-to-use Lifesaver When Needed
This product is incredibly easy to use and with the wide temperature variations in Wisconsin the number of times per month when I walk out of work or into my garage and start the car and get a “check tire pressure indicator” is about three times per month. This product connects easily, sets to the accurate pressure for my vehicle’s tires and quickly inflates to the necessary pressure before stopping. I cannot recommend this product more highly! We liked it so much we got a second one for my wife’s vehicle!
Amazon Customer –
I wish if I had it long time ago
This is a good deal great product
Marlene Castro –
BUY IT!
Dont think about it, just buy it! This has been one of the best tire inflators I have purchased. Comes with all accessories, a battery and can charge/plug into your car (of course). It inflates fast and turns off by itself once its done. It is also very lightweight and has a light if needed. The perfect size and amount of power. A must have for your car emergencies.
Jeff Pfaff –
Quick working after 4 months
Digital display works normal but doesn’t build pressure.
Tony –
This saves so much time.
I really like this drill shape tire inflator so far. I only had it for a month and have used it about ten times now. I can speak on the durability yet but the function is great. Instead of having to break out the big air compesser and extension cord every time to add air to a tire. It would be nice if they sold extra batteries for this. I’ve tried different ones from the tools I have but nothing yet fits.
Amazon Customer –
Quality between McDonalds Happy Meal Toy and early 2000’s Harbour Freight
This has a 4.7 rating which is on par with most Milwaukee products, there is no way. The picture is a 3D Cad rendering which makes it look nice, but the reality is McDonalds Happy meal toy quality plastic fit and finish.
Samuel Santana –
Excellent machine but pump adapter broke off after 5 uses..
The machine is wonderful but the adapter snapped after 5 uses. This machine was $50.00 and I expected better than this i will be returning it for a refund.
Greg Smith –
Not enough superlatives to describe how great this product is!
This tire inflator is much better than I thought any product could be for inflating automobile tires. It has all the features of any tire inflator I’ve used before and none of the drawbacks, and no more paying for 4 minutes of air at public air machines. It fills a tire in a matter of one minute or less–that is at least as fast as the public air machines. I can top off all four tires in just a few minutes in my driveway. The sound is not as loud as I expected, it is not annoying. The simplicity of use is really where this product shines To use it, just push the ON button, dial your desired pressure, connect the hose to your tire, and pull the trigger on time. The inflator shows the current pressure in the tire and updates the pressure reading while the inflator works. When the dialed pressure is reached the inflator automatically turns off. Rinse and repeat for your other tires. I love that it tells you the tire’s pressure as soon as you connect the hose, and keeps you informed in real time. I also love that you can pull the trigger and do something else while it works and you will hear it turn off so you can move it to the next tire. It’s actually fun and convenient, as opposed to being a chore to inflate tires now. Finally, I can report that I have used this inflator on car tires, large truck tires, and the small tires on a hand truck. In all cases, the inflator works the same and is simple, effortless, quick, and reliable.
Thomas Casada –
Used it twice since I bought it. Sounds like the hose has a hole in it!
Fill tires on my vehicles. I set it at 140 lbs. For my air shocks. Something inside now has a leak and it doesn’t work now!
Brady –
Carefull with this.
Bought this in June, when it worked it worked well, but in January as I was inflating a car tire. It quit and started smoking. Don’t know how to contact the company. This was so handy though I’ll probably buy another though not from Dormzie.
Amazon Customer –
Works but…
I replaced my broken pump from another company but looks similar. I was disappointed that the battery cannot be charged while it is connected to the pump. My old one allowed charging to occur so it was always plugged in when not in use. This would require extra steps that can be forgotten by teenage users and make Dad users upset.

Convenient and reliable
Compact, good build quality, good filling speed, good functionality. I don’t know how durable this is, I just got it last week.
PJ-Jim –
Nice feature, but…
The logic of the way the controls work is very good. Easier to use than my prior inflator. Only problem is tha5 it feels cheap. I will have to try not to bump it around. The “case” is cheap also. Tossed it out and will use the prior case.
NAKITA –
When in a pinch
This item is most definitely worth the money. I have had many of these due to having givin mine away to folks while on the road. Many folks when they see mine and have flats they immediately want mine. So I give mine and by a new one. It hasn’t gone saved me many times and helps with air bags on the trailer as well as the air bags on my truck.
Clint Coady –
Fiction can be fun
So the item itself is well made no doubting that. However upon usage, and after setting the PSI to 32 (My Honda CR-V cold tire inflation pressure), the unit would read nothing but 31.5 psi when hooked up to my valve stem (properly) before even depressing the button to engage the auto inflate. This was checked against two digital tire gauges which both read 28 PSI pre-inflation. Essentially the unit would turn on for about 2 seconds until it had reached the imaginary pressure of 32 PSI, and then subsequently shut off (It had reached 32 PSI in fiction). I ended up having to drive to my local gas station to use their air compressor. I wanted to leave this review in case anyone else may be considering this unit. I would look elsewhere (at least in my experience). It is sad because most of the reviews were positive. Maybe I got a lemon who knows.?

Works great!
I am a female who has used this 6 times in the past 2 days. Ease of directions and use. I’m not afraid of it. Worth it s weight in gold. Purchased for hubby for Christmas but he was hospitalized so I unwrapped it and used it! By the way I am 74.
