If you are reading this, you probably hate “waiting.”
Most tire inflators are agonizingly slow. If you drive a truck with 33-inch or 35-inch tires, a standard “cigarette lighter” pump can take 15 minutes to fill just one tire. That is an hour of your life gone every time you air back up after off-roading.
The solution isn’t another cheap Amazon gadget. It’s a power tool.
We analyzed the “Red vs. Yellow” debate on Reddit (Milwaukee vs. DeWalt) to find the absolute fastest way to inflate a tire without using a massive shop compressor. The winner is loud, heavy, and expensive—but it is blindingly fast.
Milwaukee M18 Inflator
The Brutal Verdict: Buy this if you already own “Red” tools. It fills a truck tire 3x faster than the competition, but it’s expensive if you don’t already have the batteries.

Viair 88P Portable
The Brutal Verdict: Buy this if you don’t trust batteries. It connects directly to your car battery and will run forever, but it is slower than the M18.

Fanttik X8 Apex
The Brutal Verdict: Buy this for your wife’s car or a Tesla. It’s too slow for a truck, but perfect for topping off a sedan without opening the hood.

Milwaukee M18 Inflator
- Insanely Fast: Fills a 33-inch tire from 15 to 35 PSI in under 2 minutes.
- Memory Presets: Dial in 35 PSI, hit start, and it stops automatically.
- Heavy Duty: Doesn’t overheat after 4 truck tires like the M12 or smaller pumps.
Milwaukee M18 Inflator: The Speed King
This tool is all about speed. Pure, raw power. On forums like r/Overlanding, users agree. The Milwaukee M18 is the fastest. It fills big 35-inch tires after a trail run in no time. People who own both say it’s three times faster than the DeWalt model.
But is the marketing totally honest? Not quite.
- They call it “Portable.” The truth? It’s a brick. It’s heavy, bulky, and very loud.
- It has a funny quirk. Near the end, it does the “Pressure Dance.” It stops, checks the pressure, runs for a second, and stops again. It repeats this 3-4 times.
One user put it perfectly: “It’s annoying to watch it cycle on and off. But it hits the PSI dead on every time. My advice? Just walk away and let it work.”
The Bottom Line:
If you drive a truck, SUV, or RV and already use Milwaukee batteries, buy this. It turns a 20-minute job into a quick 5-minute stop.
Viair 88P: The Wired Workhorse
This is your “Old Reliable.” It has no fancy screens. It has no batteries to charge. It just works. You connect it directly to your car’s battery with clamps. It runs on your engine’s power.
Marketing says it’s “Portable.” Here’s the reality.
You have to open your car’s hood to use it. This is a big problem for some. Imagine adding a little air in the rain. Or if you don’t like getting your hands dirty.
As one person said: “The Viair will still be working in 10 years when your lithium batteries are dead. But popping the hood just to add 2 PSI is annoying.”
The Bottom Line:
Buy this for survival-level reliability. If you’re alone in the desert, you want the pump that runs off your car. Not one that needs a charged battery.
Why Pros Often Choose Milwaukee Over DeWalt
We usually love DeWalt tools. Their 20V inflator is versatile. It can even plug into your car’s 12V outlet, which the Milwaukee cannot.
But for pure speed, it can’t keep up. User tests show the Milwaukee fills large truck tires much faster. The DeWalt tries to do everything well—from mattresses to tires. That means it’s slower on the really tough jobs.
The Bottom Line:
If you already use DeWalt tools, their inflator is fine. But if you’re buying a pump just for big tires, Milwaukee is the winner.
Final Choice: Battery Power vs. Wired Reliability
So, which one is right for you? It comes down to one simple question. Do you want speed or total reliability?
- Buy the Milwaukee M18 if:
- You want the job done now.
- You hate waiting around.
- You already own the batteries.
- Think of it as the Formula 1 pit crew of tire inflators.
- Buy the Viair 88P if:
- You want a tank that never quits.
- You don’t mind opening the hood.
- You need something to live under your seat for ten years and always work.
- Buy the Fanttik X8 Apex if:
- You just have a car or EV and need easy top-offs.
- It’s more of a handy “tech toy” than the heavy-duty options above. But it’s super convenient.
