The M18 tyre inflator seems to perform well in most tests I have seen. The smaller (more domestic high and low pressure designs) don't have the output, or endurance, required. Plus the internals simply do not last. Compressor units with a tank, do work, but they are more expensive and more bulky.
Zero surprise. Another good test is from 15-30 psi for those which offroad and air down for a much more realistic duty cycle in the real world. Dewalt has most always been a trendy lack luster thing.
I would have rather done it 15 to 30 but I couldn't consistently deflate to 15PSI as well as I could to zero. Also I wanted to show a worst case scenario.
M18 is great, but it is out of the need for 95% of people. Who needs to inflate their tire from near empty to 36, like ever? I'd still pick dewalt for it's multifunction. Inflates ballon's, air bed, etc, a must have for most household. I don't mind spending extra minute to fill from 20-35 psi (like what people actually need 99% of the time) unless you inflating tires everyday or your tire needs very high PSI, or you do off-road. For the size of M18, it's the single largest battery powered tire inflator that I have every seen, it gotta perform good. If you cut the dewalt in half (excluding the high volume side) it's just as big as M12. I think dewalt is trying to make a well all around general purpose inflator than trying to do a single thing and push to the extreme.
Well if you have a larger truck or trailer you are dealing with higher pressures so 0 to 36 is a similar test to say 60 to 80. 0 psi is easily repeatable for a more consistent test. Also 1 0 to 36 test is similar to topping off all 4 time wise. When going on a trip I top off 8 tires at high psi (truck and trailer) so to times are important because if an inflator takes 2 minutes longer multiply that by 8 and it makes a huge difference. Thanks for watching
I'm glad Milwaukee has gone to the M18. The M12 was good, but testers rarely talked about how much battery was being used by the M12. I assume the M18 is more efficient. I think that's why some of us went with the Dewalt. Better battery life, compared to the M12. May not do so well against the M18. But $180 is too high for me. Maybe $150 ish.
Great video…however, I don’t think it is actually a scientifically & accurate comparison unless you take into consideration the weight distribution of the vehicle. The two compressors in the front are attempting to inflate tires that bear more weight than the rear, since the engine compartment is supported by that area. This difference may be minimal, yet it is there. I believe measuring the mean (average) performance of all compressors over a four iteration trial, while rotating them as you would rotate the tires between each trial would suffice in providing optimal results. The only other solution would be to position the vehicle in such a way that utilizes the combination of both the grade of the driveway relative to the correlation to the specific gravity force applied (using the 1.36 constant), and only then would the current setup you have be an exhaustive experiment. Otherwise you’re just creating a hypothesis rather than actually testing it. Great video though.
I forgot to mention I bought a second motor for a Toyota matrix and put it in the back so that there would be an engine on the front and rear axle. Thanks for the comment!
Inflating to a certain psi. So anything on the front tires have a cfm advantage... but since I own the m18 inflator, I can tell you it don't matter. Get out of the lab and get into the field buddy.
It's a huge factor in pretty much eliminates any that you don't have the battery for. I'd rather have a slow one that I had batteries for then a fast one I didn't
Looks like 2 of them have on board air tanks. How do those work? Are they prefilled- do they just transfer air to the tire? The compressor still runs, so how does that work? The DeWalt has the option of battery power, or cig lighter. You used the bigger battery, why do you think it took so much longer? Nice job, keep the tests coming.
This is awesome! I like seeing the side by side comparisons.
It really puts things in perspective.

Thanks ! Most useful vid on the m18 I’ve seen yet
Great comparison video for helping me decide. Thank you!
Like to see the new Dewalt 2.5 gallon battery vs milwaukee
Good info, thank you for sharing. We need more videos like this!
I may test them on higher psi truck tires in another video
Good video. Thanks for sharing.

The DeWalt definitely has some benefits and if you have DeWalt batteries it's a no brainier.
I need one of those

cords are real short on MIL M18
Great comparison. How much does battery compatibly play into your overall choice?

Perhaps it's downgraded so that it can use the cigarette lighter without drawing over 100 watts which is max in most cars
Any inflators on the market that come with any type of illumination?
Yes I think the DeWalt has one
Dewalt makes nice tools.,but as far as batteries go, Milwaukee blows Dewalt away.
