Description
Our 20V MAX* Corded/Cordless Air Inflator can run on any one of three power sources for maximum versatility: 20V MAX* battery, 12V DC, or 110V AC. Use it on the jobsite, or on the go. Air inflator features a high-pressure rubber hose for durability. The threaded chuck and included onboard accessories make it easy to inflate items from tires to footballs. Setting desired air pressure is simple with the digital gauge, and the auto-shutoff provides accurate inflation. The high-volume hose allows fast inflation of mattresses and other inflatables with the push of a button. Move the hose to the deflation port for quick and easy take down. An onboard LED light of the portable tire inflator helps to provide illumination in dark spaces. Heavy-duty rubber feet help reduce walking while in use. Battery, charger, and AC power adapter are sold separately.

I have 3 vehicleas tha tremind me when my tires are low. I also have a pancake air compressor, but its always a hassle to drag it from where I keep it in the basement, to where the cars are, and mess with an extension cord or long curly tailed air hose. So I’d inflate the tires at a gas station and deal with ensuring I had change for the air pump, or go somewhere where it was free. Not very convenient.
I already have a number of DeWalt 20v tools, so battery is not a problem. With a normal air pump, you have to stoop over the tire and hold the inflator hose to the tire valve stem. With this one, you just screw it on the valve stem and it tells you the existing air pressure. You rotate the little wheel to set your target pressure, press the button and let it pump. It will shut down when the target pressure is reached. It took me about 15 minutes to do 8 tires maybe added 3-5 psi to each tire.
If you dont have a DeWalt battery, but have another brand, maybe look into a battery adapter. I think DeWalt was smart in not including a wall cord. It would have added a lot of cost to the product for a feature that most people would not use.

This inflator REALLY WORKS and WORKS WELL!
Purchased to have a “quickly available” inflator for my car tires. This unit, powered by a (fully charged) 5AH pack, topped off my car tires (from 30 psi to 34 psi) quickly (approx. 2 min per tire), efficiently, and didn’t “eat up” the battery (still showed “3 bars” after use). The pressure control is fairly intuitive: turn the unit on, connect the hose to the valve, and rotate the wheel to set the desired pressure. After that, press the button in the middle of the wheel (the pump starts approx. 1 second later) to start the pump. When it reaches the set pressure, it shuts off. Disconnect the hose and move to the next tire. NOTE: when operating as a “tire pump”, lay the unit ON ITS’ BACK so the pressure gauge and controls FACE UP. The hose is long enough to reach the valve, even if it’s positioned at “12 o’clock” on the rim.
Weight: with a battery, it’s not much heavier than a drill motor. The handle makes it very easy to move from place to place.
Noise: yes, it’s “noisy”, but not much more than the coin-operated pumps at convenience stores and gas stations. Plus, YOU DON’T NEED ANY COINS!
Storage: toss it into the back seat or trunk – it’ll be there if/when you need it next!
One “nit”: I wish it came with a “quick connect” for tire valves. While it isn’t too difficult to SCREW the fitting on a valve, it does take time. I’m sure there are “quick connect” valves around that screw onto the hose end.
Price: Yes, it’s pricier than many other inflators, but you’re dealing with DEWALT QUALITY. If you’re a DeWalt 20V tool user, just consider it as another Good Tool Investment! 🙂
Otherwise, I ** DO HEARTILY RECOMMEND ** this unit for ANYONE in the “DeWalt ’20V Universe'” who has to deal with those occasional “low-inflation situations”.

Love this little compressor! I rarely write reviews on things but have to say this is one of my FAVORITE dewalt things (and I have several of their battery powered tools). The back tire of my John Deere 5105 was completely flat and severely cracked. I was dreading having to take it off. Went and got some “slime” and put it in, said a little prayer and pumped it up. I had a 6AH battery on it and it worked amazingly well! It has a feature that allows it to shut off when it reaches pressure. Also great for road trips…has light, charging ports, and you can air up your kiddos sport equipment (balls and bike tires) or your pool floats and air mattresses. Would very highly recommend this! Worth every penny!

I once had a little portable compressor that plugged into the cigarette lighter and it was terrible. The quick connect valve would leak air, it was slow, it was hard to stow. So some years later, when I bought my first real air compressor, I tossed that and never looked back. It was, after all, a real tool and naturally it did a perfectly good job of filling tires. It never again occurred to me to consider a lightweight portable compressor.
Recently, though, a stem on one of my wife’s tires was slow leaking and she asked me to show her how to do it herself until she could get it to the tire shop. As I showed her what to do, it occurred to me that it’s actually something of a pain… test with the air gauge, put on ear protection, set the compressor running, get the hose off the wall and hook it up, attach the tire tool, set the output pressure, fill the tire, test it with the gauge, fill again maybe, do that for the other three, turn off the compressor, turn off the output pressure, wind and store the hose and tire tool, release the extra pressure, open the moisture drain…
Shortly thereafter, someone online mentioned this tool. Since I’m already invested in the Dewalt 20v ecosystem, it seemed like a good option and I bought this as a bare tool. I tested it out on our three vehicles and it works brilliantly. It is sturdy, but small and easy to carry. I just grab any Dewalt battery and it’s ready to go. I really love that it screws onto the tire instead of using a quick connect valve. Those always leak and this is secure. There is no going back and forth between the gauge and the hose to get the pressure right. Set the target pressure, press the start button and it does the rest. It consistently stops about 0.5 above the setting, which is probably perfect by the time I lose a bit of air removing the hose. I don’t know how long the battery will last, but I did 3 cars on a fully charged 2 Ah battery and there are still three lights on the battery. That works for me.
Best of all, my wife feels like she can handle this. She was intimidated by all the steps of using the big compressor, but she finds this as convenient and easy as I do. I should have bought this a long time ago.

There are a number of tools I have for my old Mercedes that I know I will use maybe once every year or longer. But when you need them you need them.
Tools such as one to pull the instrument cluster.
I’ll check my tires at least once a month. That should be standard procedure for everyone. Came across one last week where it was down to 18 pounds and took it in to have the leak fixed
When service stations did car repair work they all had nice big air compressors for their air tools and of course hoses to fill tires.
Remember when every island by the gas pumps had a hose for water for the coolant and a air hose for the tires?
Those days are long gone, with the disappearance of repair shops in service stations. If a self-serve station has an air compressor at all it’s some dinky little thing in the back and most want $1.50 for three minutes to fill your tires.
And that’s if the thing works. And of course I spent a number of years running around the car trying to fill each tire before the time went out
Anyway a friend told me about this little portable Dewalt air compressor.
It arrived yesterday and I spent today just filling the spare tires of my cars.
That’s some thing that virtually everybody ignores, including me. And of course the worst time to find out it’s low on air is when you need it out in the middle of nowhere.
One of them that hadn’t been checked since new, 11 years, was down to 10 pounds when it should’ve had 61 pounds . And of course normally when you find that out it’s when you need it
One thing I advise when you’re getting this get the bigger battery. I got the middle one at 4 A/h.
The only thing that surprised me a bit is after filling these three spares today – the usage light on the battery was down to two from the three. so I suspect if you’d had the standard battery I pretty much would’ve used it all.
The other thing that surprised me is how accurate the built-in pressure governor is. Set it to 33 pounds and it automatically fills it to 33 pounds and then stops. I verified it with my hand-held digital tire pressure gauge.
Another nice feature that I had to figure out?
Every hose I’ve ever used do you have to keep it pressed into the Schrader valve. This one just screws in and you just leave it alone while the compressor does its thing. It’s a nice thought-out feature.
So my summary is that this is a worthwhile investment that you will probably use at least every month
You can’t even depend on the car’s tire pressure monitoring system to give you an accurate reading. The one on my 2011 Mercedes is 5 pounds optimistic. I suppose what it is still good for is detecting a massive leak.
And the federal government mandated these for newer cars because people don’t check their tire pressure.
And why is this important? A low pressure tire is in danger of a blowout with the added heat not to mention a degradation in handling.
So I am glad that I got this finally.
I’ll even take it on long trips because looking at that little dinky spare tire in my 2011 Mercedes and the hassle of changing it to a spare it would be nice to have a pump just to pump it up with air and get you do a tire shop
This is a tool that I know I will use on a regular basis.
Edit 12-5-22 as I am typing this I’m sitting in an Elko Nevada hotel room. I had taken the 2011 on a 2000 mile trip to Minneapolis. And on the way back I had a tire issue
As it turns out I really did use the air compressor. The other day in Wendover Utah I came out the next morning and the rear tire was completely flat. Now that alone would’ve taken out a good part of the day being it was in a motel parking lot. call AAA wait a number of hours-& since the things completely flat they probably have it towed somewhere unless they have air compressors. incidentally the spare is this little donut thing that I wouldn’t drive the remaining 500 miles on.
Anyway out came the Dewalt and in about three or four minutes the completely flat tire was full and used another bar from the battery
So why am I in Elko? I wanted to get the flat fixed and then trying to take it off the rim the machine tore the sidewall and of course there was not another Perelli tire in my size in Elko Nevada so I was having to wait until Monday for one to be delivered
Anyway on a trip I am not going to leave this

Pros: The unit is light and easy to use. I prefer the screw on valve connection to the quick release style. While harder to engage than a quick-release, it’s more secure and the air lost during disconnection is predictable and minor. It can also be used to let air out in a controlled way if you overshoot. The unit is well built overall. The noise level is fair, about what I expected for this style of pump. The pressure accuracy is very good, and the auto-shutoff works perfectly.
Cons: “Our 20V MAX* Corded/Cordless Air Inflator can run on any one of three power sources for maximum versatility: 20V MAX* battery, 12V DC, or 110V AC.” Not!
I purchased this unit with the idea of using it for my car (12 VDC) and around the yard, for filling the tires of wheelbarrows, etc. I expected to be able to plug it into 120V AC as the Amazon description implied, but soon found out that its has no 120V input. I can’t fault DeWalt – their literature does say (with a buried double **) that you need an AC adaptor, sold separately. For Amazon to say that it runs on 120V is exactly like saying my iPhone runs on 120V – all you need to do is buy an AC adapter (sold separately). If this is important to you, consider other pumps that clearly do run on 120V. I dinged it two Ease of Use stars for false advertising.
The only design shortcoming I noticed is that the 13 foot 12V power cord could be about 4 feet longer, to stretch around the car so that it can reach all four tires without having to transfer the power cord from one side of the car to the other. The pressure set point is not preserved when the unit powers down, so it needs to be continually reset.

So simple to use. Just spin the dial and input the desired air pressure. The unit is very portable and light, but also packed with enough power to easily inflate a care tire to 30 psi in 3 mins. The only downside is that the unit does not come with a battery, you’ll need to buy that if you want full portability. The included wall plug and Car DC cord are long and don’t fit well into the storage compartment on the unit. Other than those minor drawbacks, this unit is built like a take, seems very reliable and has come in handy more than a few times.

My husband and I both drive lift Jeep Wranglers and of course our tires are bigger than the average tire. We’ve tried other at home air compressors, but after a couple tires they tend to either kill over or start smoking. We read reviews on this one and everyone said they had good luck with airing up bigger tires. It went on sale and we have a ton of DeWalt batteries so we decided to try. When we got it the temperature was starting to drop outside and that’s the normal time when tires lose air. We tested it out on his tires….did amazing and never got hot, died, or started smoking. We took a chance and did mine right after. Still worked like a champ. Love the fact it has a air setting so it’s a set, turn on and let it do it’s thing. Easy to use and well worth the price if it can do ten tires and not break. Would recommend for those big tire lovers out there.

The first thing to understand about this, is that it’s THE perfect tire inflator for anyone who owns cars and trucks. The second thing to understand about it, is that it’s part of a SYSTEM, and that when you get it, it’s incomplete. Yes, it comes with a power cord that’s designed to plug into your car’s cigarette lighter, but it doesn’t come with a wall plug or a battery. Buying both of those will set you back another $200 or so. The good news is that the power chord is long enough to enable you to reach all four tires on normally-sized vehicles. I haven’t tried this on an F-350 with a long bed or anything, but it works great for our three Toyotas. The coolest thing about it, is that you can set what PSI you want it to go up to, and then just hit the button and walk away until it’s done. It takes the tire right up to the pressure you want, and then you can just screw on the valve stem cap and move on to the next one. I purchased the wall plug for another $50, because sometimes I want to pump up tires on a vehicle that isn’t running, and this pump draws enough current that sometimes it will shut down on just the car battery alone. The battery and charger looks like it’s going to be another $150 or so, and honestly I just can’t be bothered to buy them yet. If I had a bunch of Dewalt tools that all took the same battery, I’d buy it. And who knows? I like this air pump so much that I might end up there. Just understand that, out of the box, it’s only equipped to run off of your cigarette lighter. I was somewhat taken aback by that at first, but I got over it and moved on to enjoying how great it works and how easy it is to use. Also, it feels durable and substantial, like it was built more for construction sites than for your garage. Which is a plus in my eyes.

This is the easiest and most useful tool created by Dewalt. This item is lightweight and allows for easy fillup for any size tires including compact tractors. First use, it needs to warm up and break in before it starts to function like its supposed to. Remember that it’s a tiny electric motor rather than a 2HP air compressor running on 120VAC.
As mentioned this device is lightweight and can fit in any vehicle even if its loaded down for road trips. Easy to charge and easy to disconnect the line. Not only can you fill up your tire but inflatables as well.
