We checked out a bunch of them to find the best portable tire inflator for trucks, looking at things like how fast they work, how long the battery lasts, and how easy they are to use.

Key Takeaways

• The AstroAI Cordless Tire Inflator is a solid choice, especially if you're looking for a good value and don't need to inflate massive truck tires.

• For trucks and SUVs, the Viair 88P is a strong contender, offering good power and a decent price, though it does need to be plugged into your car's battery.

• If you're already invested in DeWalt tools, the DeWalt 20V MAX Tire Inflator is a convenient option that works well.

• The Milwaukee M18 Tire Inflator is another powerful cordless option, known for its speed, but you'll likely need to buy the battery and charger separately.

1. AstroAI Cordless Tire Inflator

When you're out on the road, especially with a truck, having a reliable way to check and adjust your tire pressure is pretty important. The AstroAI Cordless Tire Inflator is a solid choice for a lot of folks. It's got this unique look, kind of like a power drill, which might throw you off at first, but don't let that fool you. This thing is built tough and gets the job done.

One of the best things about the AstroAI is how it gives you options for power. You get a rechargeable lithium-ion battery pack, which is great for when you're away from your truck. But if that battery runs low, or you just prefer it, you can also plug it into your vehicle's 12-volt outlet. This means you're pretty much covered no matter what.

Ease of Use and Features

The digital display makes setting your target pressure straightforward. You just set it, hit the trigger, and it automatically stops when it reaches the PSI you want. No more guessing or constantly checking. It's also not super loud and doesn't get ridiculously hot, which is a plus. The battery can handle topping off about four tires from 25 to 35 PSI before needing a charge, which is usually enough for most situations.

Performance on Truck Tires

While the manual might suggest it's more for cars and smaller vehicles, we tested it on a truck tire. It managed to inflate a large truck tire from 20 psi up to 60 psi on a single battery charge. It took a bit longer, around 18 minutes and 53 seconds, but it did it. So, if you're in a pinch with your truck, it can definitely help out.

What's in the Box

• Rechargeable lithium-ion battery pack

• 12-volt adapter for vehicle power

• Carry bag

• Needle adapter for sports balls

• Inflatable toy adapter

• Spare chuck

This inflator is a good all-around option, especially if you want the flexibility of battery power or plugging into your car. It's not the fastest for big truck tires, but it's dependable and easy to use.

For anyone needing a portable air compressor that's easy to set up and operate, the AstroAI is a strong contender. It effectively inflates tires to a set pressure and automatically shuts off once the desired level is reached, making it a user-friendly tool for maintaining your vehicle's tire pressure.

2. Viair 88P

If you're looking for serious power and speed, especially for larger truck tires, the Viair 88P is a solid contender. This thing is built tough, like a scaled-down version of their industrial compressors. It really shines when you need to inflate bigger tires quickly, like those found on many trucks and SUVs. In our tests, it absolutely crushed the competition when it came to speed, getting a 215/70 R16 tire from 10 to 45 psi in just over three minutes. That's seriously fast.

Power Source and Connection

The 88P connects directly to your vehicle's 12V battery using alligator clips. While this might seem a bit old-school, Viair explains it's necessary to get the 16–19 amps the compressor motor needs to run effectively. Plugging into a standard accessory port wouldn't provide enough juice and would likely blow a fuse. It’s a good idea to keep your car running while you use it to avoid draining your battery. The 10-foot power cord and 16-foot heavy-duty rubber hose give you a decent reach, over 26 feet in total, which is usually plenty.

Inflation Speed and Gauge Accuracy

This compressor is a speed demon. It's the fastest option we tested for larger tires, making it a great choice if you frequently air down for off-roading and need to reinflate quickly. However, the built-in analog gauge isn't the most precise. It can read a bit high, so you might need to shut it off and check with a separate gauge to get a truly accurate reading. It’s not a deal-breaker, but it does mean you need to pay a bit more attention to avoid over-inflation, especially since there's no automatic shut-off feature.

Durability and Heat

Viair is known for making reliable gear, and the 88P is no exception in terms of build quality. It comes with a sturdy carrying case that keeps everything organized. One thing to note is that the compressor can get pretty hot after running for a while, up to 160 degrees Fahrenheit. So, be careful when handling it after extended use, as the heat exchanger is located near the handle. If you need a powerful inflator for larger tires and don't mind the direct battery connection and a bit of extra attention to the gauge, the Viair 88P is a strong performer. For those who need something a bit more convenient, you might want to check out the Viair digital tire inflator.

Key Features:

• Fastest inflation times for larger tires.

• Connects directly to vehicle battery via alligator clips.

• Includes a 16-foot heavy-duty rubber hose with a brass chuck.

• Comes with adaptors for various valve types.

• Built-in analog pressure gauge (note potential inaccuracy).

• Includes a spotlight that activates when connected to the battery.

• Comes with a durable carrying case.

While the Viair 88P's direct battery connection and analog gauge might seem a little dated, its raw speed and power for truck tires are undeniable. It’s a workhorse that gets the job done efficiently, especially for those who prioritize performance over convenience features.

3. DeWalt 20V MAX Tire Inflator

Power and Versatility

The DeWalt 20V MAX Tire Inflator is a real workhorse, especially if you're already in the DeWalt tool ecosystem. This inflator really shines with its multiple power options, letting you run it off DeWalt's 20V battery packs, your car's 12-volt outlet, or even a 110-volt wall plug with an adapter. That kind of flexibility means you can use it pretty much anywhere, from topping off your truck tires to inflating air mattresses at the campsite. It’s built tough, too, with rubberized feet that keep it from sliding around, which is handy when you're working on uneven surfaces.

Performance Metrics

When it comes to speed, the DeWalt 20V MAX holds its own. In our tests, it took about 7 minutes and 42 seconds to inflate a truck tire from 10 psi up to 45 psi. For heavier duty, like going from 20 psi to 80 psi, it averaged around 32 minutes and 36 seconds when using a 5Ah battery. It’s not the absolute fastest on the market, but it’s definitely respectable for a portable unit.

Key Features and Considerations

• Multiple Power Sources: 20V battery, 12V car adapter, 110V wall adapter (sold separately).

• Included Accessories: High-pressure and high-volume hoses, various nozzles, a Presta valve adapter, and an inflator needle.

• Onboard Storage: Keeps accessories organized and easy to find.

• LED Light: Built-in light for nighttime use.

• Pressure Recalibration: Sensor can be recalibrated for high elevations, though it resets when turned off.

One thing to note is that the battery and charger aren't included, so factor that into the cost if you're not already a DeWalt user. It’s also a bit on the larger side compared to some other portable inflators, but its robust build and versatility make it a solid choice for truck owners who need a reliable tool. If you're looking for a dependable option that can handle various inflation tasks, this DeWalt unit is definitely worth considering, especially if you need to check your Tesla extended auto warranty coverage and ensure your tires are properly inflated.

While it lacks an integrated accessory charger for phones, its overall build quality and adaptability make it a strong contender for anyone needing a powerful portable inflator.

4. Milwaukee M18 Tire Inflator

Milwaukee really stepped up with their M18 Cordless Tire Inflator. This thing is a beast, capable of inflating everything from your car's tires to larger truck and SUV tires in what feels like no time at all. If you're managing a fleet or just have a lot of vehicles to keep aired up, this Milwaukee inflator is built tough for the job. It's got this neat memory function that lets you save pressure settings for up to four different tires. So, you can punch in the right pressure for your work truck, your trailer, your spouse's car, and even that ATV you've got stashed away. Just use the plus/minus buttons to cycle through your saved presets, labeled M1 through M4 on the unit.

Even though it's built like a tank and has a bit of heft to it, the M18 is surprisingly straightforward to use. Milwaukee clearly put some thought into making it simple, which is a nice touch alongside its solid construction.

Features and What's Included

The M18 comes with a decent air hose that has a Schrader chuck built right in. You also get a needle for sports balls, a general inflator nozzle, and a Presta valve adapter. The hose conveniently wraps around the back of the unit for storage, keeping the attachments tidy too.

Keep an eye out for the temperature protection indicator and an overload indicator. These flash little icons on the digital display – a thermometer and a triangle with an exclamation point, respectively – when certain conditions pop up. The temperature warning might flash if you're using it for a while in really hot or cold weather, or if the airflow gets blocked. If that happens, just give the M18 about ten minutes to cool down or warm up before you try again. Restricted airflow can also trigger the overload protection. Milwaukee suggests checking your connections for any blockages if that light comes on.

Battery and Power

Now, here's something to note: the Milwaukee M18's only power source is its rechargeable battery pack. If this is your first Milwaukee M18 tool, you'll need to buy a charger and batteries separately, which can add a chunk to the cost. However, if you're already invested in the Milwaukee M18 battery system, adding this inflator to your collection makes a lot of sense. It's a powerful cordless inflator that can tackle car tires in record time.

Using the Milwaukee M18

Setting your desired pressure is easy with the plus/minus buttons. To avoid over-inflation, the M18 has an automatic shut-off that kicks in once it hits your set pressure. There's also a manual mode for anything under 10 psi. While it might seem like overkill for a beach ball, it's way better than a manual pump!

Milwaukee also included an "Auto Pressure Check" feature. It pauses the inflator at the end of a fill to let the pressure settle, then does a quick check. According to Milwaukee, it might even continue inflating a bit after this check to get the most accurate reading. This auto check can happen up to five times, depending on the job.

For extended use, Milwaukee suggests giving the M18 some downtime to cool off. They recommend about 40 minutes of cool-down time for every 20 minutes of use. This helps keep the tool in good shape for the long haul.

This inflator is a solid choice for anyone needing serious power and speed, especially if you're already in the M18 ecosystem. It's built for durability and performance, making it a reliable tool for keeping your truck's tires properly inflated. You can find more details about its capabilities on Milwaukee's website.

5. Fanttik X8 Apex

The Fanttik X8 Apex is a pretty neat little gadget. It’s compact, which is always a plus when you’re trying to save space in your truck or car. This inflator is surprisingly fast, capable of topping off a standard car tire in under a minute. It’s got a digital display that makes setting your target pressure straightforward, and it automatically stops when it hits that mark, which is handy for avoiding overinflation. Plus, it comes with adapters for different types of valves, so you can use it on bikes and other things too, not just your truck tires.

Key Features and Performance

This thing is pretty versatile. It has preset modes for cars, motorcycles, bicycles, and even balls. You can also set a custom pressure, anywhere from 3 psi all the way up to 150 psi, which is more than enough for most truck tires. On a full charge, Fanttik says it can handle about four car tires, which seems about right based on my experience. It’s not really built for big truck tires, but for a pickup or SUV, it’s usually fine for topping them off or handling a slow leak in a pinch. It also has a built-in flashlight, which is a nice touch for those dark roadside situations, and a USB port to charge your phone if your battery is dead. That’s a pretty good combo for an emergency kit.

Battery Life and Charging

Charging the X8 Apex takes a couple of hours, usually around two to two and a half. Once it’s full, you can expect roughly 40 minutes of continuous use. It’s a good idea to charge it up after you’ve used it a lot, just to make sure it’s ready for the next time. Fanttik claims it can inflate a lot of tires or balls on one charge, but realistically, for a truck, you’re probably looking at getting a couple of tires done before needing to recharge, especially if they’re really low.

What’s in the Box

When you get the Fanttik X8 Apex, it comes with the inflator itself, a rubber air hose that’s about 18 inches long, a needle adapter for sports balls, and a Schrader-to-Presta valve adapter for bikes. Everything fits nicely into a storage bag, which keeps all the bits and pieces together. The hose is flexible, making it easier to connect to the valve stem, even if your wheel is turned.

While it's not designed for heavy-duty truck tires, the Fanttik X8 Apex is a solid choice for smaller vehicles or as a backup for larger ones. Its speed, ease of use, and extra features like the flashlight and power bank make it a convenient addition to any roadside emergency kit. It’s a good option if you want something compact and multi-functional for your car tires.
