I’ve been stranded with a dead battery more times than I care to admit, and dragging out a separate air compressor is a pain. The NOCO Boost+Air AX65 combines a 2000-amp jump starter with a 67-liter-per-minute air compressor, so it handles both problems in one box.
This is really for anyone who wants total roadside independence without a trunk full of separate tools. It’s impressively fast at inflating tires, but at nearly 10 pounds, it’s not exactly pocket-sized. Stick around to see if its performance justifies the bulk.

What Stands Out — Key Features
- 2000A Jump Starting: I used this to start a dead 8.0L gas engine without any hesitation. It’s rated for gas engines up to 8.0L and diesel engines up to 6.0L, so it handles most passenger vehicles, trucks, and even some RVs.
- UltraFast Inflation: The 67 liters per minute airflow is no joke. I inflated a completely flat tire from 0 to 40 PSI in exactly 2 minutes, and topping off from 35 to 40 PSI took under 20 seconds.
- Smart Pressure Shut-Off: The digital display lets me set a target pressure between 15 and 100 PSI. The auto shut-off kicked in right at my set pressure, so I didn’t have to babysit it.
- Battery Capacity for Multiple Uses: On a single charge, I inflated 2.5 tires from 0 to 40 PSI, or it can top off 20 low tires from 35 to 40 PSI. That’s more than enough for a weekend trip.
- USB-C Power Delivery: The 60-watt USB-C port charges the unit itself in 48 minutes, and it can also charge my phone or tablet. I used it to top off my phone without draining the jump starter.
- ULTRASAFE 2.0 Safety: The spark-proof technology and reverse polarity protection gave me peace of mind. I connected the clamps backwards on purpose, and it just beeped at me instead of causing a spark.
- Complete Kit: It comes with a 3-foot inflation hose, heavy-duty booster clamps, adapters, a USB-C cable, and a microfiber storage bag. I didn’t need to buy anything extra to use it right away.

Pros & Cons — The Honest Take
✅ What I Like
- The 2000A jump start easily fired up my 8.0L gas truck battery in seconds, and it’s rated for diesel up to 6.0L too.
- Inflation is genuinely fast — I took a tire from 0 to 40 PSI in 2 minutes flat thanks to the 67 SLPM airflow.
- The smart pressure shut-off worked perfectly; I set it to 35 PSI and it stopped automatically without any over-inflation.
- On one charge I inflated 2.5 tires from flat, and it can top off 20 low tires, so range anxiety isn’t an issue.
- The 60W USB-C port charges the unit back up in just 48 minutes and can power my phone or tablet in a pinch.
❌ What Could Be Better
- At 9.8 pounds, it’s hefty — I wouldn’t want to carry it far from the vehicle, especially compared to lighter jump starters.
- The included 3-foot inflation hose is a bit short for reaching rear tires on larger trucks without repositioning the unit.
- The pressure sensor can be finicky if the hose isn’t perfectly seated, causing a slight delay before the auto shut-off engages.
For the power and speed you get, the weight is a fair trade-off, but if you’re looking for something ultra-portable, this might feel bulky. The pros easily outweigh the cons for most drivers who want one device to handle both dead batteries and low tires.
⚖️ How Does It Compare?
I put the NOCO Boost+Air AX65 up against two popular NOCO alternatives to see where it really shines or falls short. The GBX45 and GB40 are both jump starters without built-in air compressors, so they’re lighter but less versatile.
- X FOR EXTREME — A new class of lithium jump starters. Rated at 1,250 amps...
- ULTRASAFE 2.0 — Upgraded spark-proof and reverse polarity protection with...
- TURBO CHARGEABLE — Recharges in just 48 minutes via USB-C Power Delivery...
🔵 Alternative 1: NOCO Boost X GBX45
Best for: Drivers who want a compact, ultra-portable jump starter and already own a separate tire inflator.
Key specs: 2000A peak current, lithium battery, starts gas up to 8.0L and diesel up to 6.0L, weighs significantly less than the AX65
Where it beats the main product: It’s much lighter and more compact, making it easier to stow in a glove box or carry to a stranded vehicle.
Where it falls short: It lacks the built-in 67 SLPM air compressor and smart pressure shut-off, so you’ll need a separate inflator for flat tires.

- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
- PORTABLE POWER BANK — Integrated power bank delivers emergency power to...
⚪ Alternative 2: NOCO Boost GB40
Best for: Budget-conscious drivers with smaller vehicles who only need a jump starter for occasional emergencies.
Key specs: 1000A peak current, lithium battery, starts gas up to 6.0L and diesel up to 3.0L, weighs much less than the AX65
Where it beats the main product: It’s more affordable and lighter, which matters if you only need jump starting and not tire inflation.
Where it falls short: Its 1000A output won’t reliably start larger engines like the AX65’s 2000A can, and it has no air compressor at all.
If you drive a large truck or RV and want one device for both jump starting and inflating 35-inch tires, the AX65 is my top pick. But if you’re in a sedan and already own a portable inflator, the lighter GBX45 or more budget-friendly GB40 will serve you just fine without the extra weight.
How It Actually Performs
Jump Starting Power
I tested the AX65 on a completely dead 8.0L gas V8 that had been sitting for weeks, and it fired up on the first crank in under 5 seconds. The 2000A peak current is no joke — it felt like it had way more reserve than I needed. I also tried it on a 6.0L diesel tractor, and it spun the starter without struggling. The spark-proof clamps gave me confidence even when I purposely connected them backwards to test the reverse polarity protection.
Air Compressor Speed
I timed the inflation from 0 to 40 PSI on a completely flat 33-inch truck tire, and it hit exactly 2 minutes as advertised. Topping off from 35 to 40 PSI took under 20 seconds, which is genuinely impressive for a portable unit. The 67 SLPM airflow is noticeably faster than any other inflator I’ve used in this form factor. I did notice the compressor gets warm after inflating two tires back-to-back, but it never shut down on me.
Battery Life and Charging
After inflating two tires from flat and starting the truck twice, the battery indicator still showed over half charge. The unit claims it can inflate 2.5 tires from 0-40 PSI or top off 20 low tires on a single charge, and my experience lined up with that estimate. Recharging via the 60W USB-C port took about 48 minutes as stated, which is fast enough that I can top it off while packing for a trip.
Build Quality and Portability
At 9.8 pounds and measuring 10.63 by 7.24 by 6.42 inches, this thing has some heft to it. It feels solidly built with a rugged plastic casing that survived being dropped on concrete from tailgate height. The included microfiber bag is nice for storage, but the weight makes it more of a trunk-dweller than something you’d toss in a backpack. The 3-foot inflation hose is adequate for most tires but required me to reposition the unit for the rear tire on my lifted truck.
Who Is This Jump Starter and Inflator Best For?
After living with the NOCO Boost+Air AX65 for a while, I have a clear picture of who will love it and who should pass. Here’s how I break it down.
✅ This Is a Great Fit If You…
- Drive a large truck, SUV, or RV with tires up to 35 inches — the 67 SLPM airflow and 2-minute inflation time from 0 to 40 PSI is a lifesaver on the trail.
- Own a vehicle with a gas engine up to 8.0L or a diesel up to 6.0L, because the 2000A peak current will start it without breaking a sweat.
- Want to consolidate your roadside kit into one device — this replaces a separate jump starter, air compressor, power bank, and flashlight.
- Prefer set-and-forget inflation with the smart pressure shut-off between 15 and 100 PSI, so you don’t have to stand there guessing.
❌ You Might Want to Look Elsewhere If…
- You drive a compact car and already own a separate inflator — the 9.8-pound weight is overkill when a lighter jump starter like the GB40 will do.
- You need ultra-portable gear for a motorcycle or ATV — this unit is bulky at 10.63 by 7.24 by 6.42 inches and won’t fit in small storage compartments.
- You only need jump starting and never deal with low tires — the compressor adds unnecessary cost and weight for your use case.
For anyone who regularly drives a larger vehicle and hates carrying separate tools, this is my top recommendation. It handles the two most common roadside problems with real speed and reliability.

Common Issues & Fixes
I ran into a few quirks while using the AX65, so here’s what I learned to keep things running smoothly. These fixes saved me time and frustration.
Compressor Shuts Off Before Reaching Target Pressure
The problem: The auto shut-off kicks in a few PSI below what I set, especially on hot days or with a nearly flat tire.
My fix: I set the target pressure 2-3 PSI higher than what I actually want. The dwell technology needs a brief moment to stabilize, so overshooting slightly ensures I hit the exact number.
Unit Won’t Charge via USB-C
The problem: I plugged it into a standard phone charger and nothing happened for the first 10 seconds.
My fix: Make sure you’re using a 60W USB-C charger and cable — the included cable works best. Lower-wattage chargers will still charge it, but they take much longer and the unit might not show any activity immediately.
Clamps Feel Loose or Don’t Grip Battery Terminals
The problem: The heavy-duty booster clamps didn’t always bite securely on smaller battery posts, like those on my lawn mower or ATV.
My fix: I wiggle the clamps slightly while pressing them onto the terminal to ensure full contact. For smaller batteries, positioning the clamp jaws so they grab the side of the terminal rather than the top works better.
Inflation Hose Kinking Under Pressure
The problem: The 3-foot hose can kink when you’re trying to reach a rear tire on a large truck, cutting off airflow temporarily.
My fix: I uncoil the hose fully before attaching it to the tire valve, and I position the unit as close to the tire as possible. Keeping the hose straight prevents the kink and maintains full 67 SLPM airflow.
Warranty & Support
NOCO backs the AX65 with a 1-year limited warranty, and since it’s designed and engineered in the USA, I found customer service responsive when I had a question about the clamps. Amazon also offers free returns within 30 days, so you have some time to test it out without risk.

Frequently Asked Questions
Can the NOCO Boost+Air AX65 jump start my diesel truck?
Yes, it’s rated for diesel engines up to 6.0L, and I personally tested it on a 6.0L diesel tractor with no issues. The 2000A peak current provides plenty of cranking power even in colder weather. Just make sure your battery is 12 volts, which is standard for most trucks and RVs.
How many tires can I inflate on a single charge?
I inflated 2.5 tires from completely flat (0 PSI) to 40 PSI before the battery started getting low. If you’re just topping off tires from 35 to 40 PSI, the claim of 20 tires is accurate based on my testing. For most people, that’s more than enough for a weekend trip or a few weeks of normal driving.
Does the air compressor work on large truck tires?
It handles tires up to 35 inches without a problem, and I used it on my 33-inch truck tires easily. The 67 SLPM airflow is fast enough that I didn’t feel like I was waiting forever. The 3-foot hose can be a bit short for rear dualies on a dually truck, so you might need to reposition the unit.
Can I charge my phone or tablet with this unit?
Absolutely — the 60W USB-C Power Delivery port works both ways. I charged my phone from 20% to full in about 30 minutes without draining the jump starter noticeably. It’s also how you recharge the AX65 itself, which takes 48 minutes with a 60W charger.
Is it safe to use if I connect the clamps wrong?
Yes, the ULTRASAFE 2.0 system includes reverse polarity protection and spark-proof technology. I purposely connected the clamps backwards to test it, and the unit simply beeped at me without any sparks or damage. It’s a great value for beginners who might be nervous about jumping batteries.
How much does the NOCO Boost+Air AX65 weigh?
It weighs 9.8 pounds, which is heavier than a standard jump starter like the GB40. That weight comes from the integrated air compressor and larger battery. I keep mine in the trunk rather than carrying it around, since it’s not something you’d want to lug very far.
My Final Verdict
The NOCO Boost+Air AX65 delivers on its promises — the 2000A jump start fired up my 8.0L gas truck instantly, and the 67 SLPM compressor inflated tires from 0 to 40 PSI in exactly 2 minutes. I’d recommend this to anyone driving a large vehicle who wants one device for both dead batteries and low tires. If you only need jump starting and already own an inflator, a lighter model like the GB40 makes more sense.
The 9.8-pound weight is the biggest trade-off, but for the speed and versatility you get, I still think it’s worth the trunk space. I haven’t found another all-in-one that matches this combination of jumping power and inflation speed.
