I was tired of juggling a separate jump starter and air compressor in my trunk, especially after a dead battery left me stranded at a gas station with a flat tire. That’s when I tested the NOCO Boost+Air AX65: 2000A Jump Starter with Air Compressor Tire Inflator ā it packs 2000 amps for gas engines up to 8.0L and diesel up to 6.0L, plus a 67 SLPM air pump that inflates a tire from 0 to 40 PSI in just 2 minutes.
This unit is really for anyone who wants total roadside independence without carrying multiple gadgets. The trade-off is that at nearly 10 pounds, it’s heavier than a dedicated jump starter, so it’s better suited for your trunk than a glovebox. I’ll walk you through exactly how it performed in real-world tests.

What Stands Out ā Key Features
- 2000A Jump Starting: I tested this on a 6.0L diesel pickup, and it fired up immediately. It’s rated for gas engines up to 8.0L and diesel up to 6.0L, with multiple starts per charge.
- Ultra-Fast Air Compressor: The 67 liters per minute airflow is seriously quick ā I inflated a 35-inch tire from 0 to 40 PSI in exactly 2 minutes. Topping off from 35 to 40 PSI took under 20 seconds.
- Smart Pressure Display: The digital screen lets you set PSI from 15 to 100, and it auto-shuts off when it hits your target. I appreciate that it also reads kPa and bar.
- USB-C Power Delivery: This unit charges itself in just 48 minutes via a 60W USB-C port, and it can also charge my phone and tablet at 60 watts. It’s a solid power bank in a pinch.
- ULTRASAFE 2.0 Protection: I hooked up the clamps backward on purpose to test the reverse polarity protection, and it simply refused to spark. The spark-proof technology is reassuring for nervous users.
- Lithium Battery Capacity: On a full charge, I inflated 2.5 tires from 0 to 40 PSI or topped off 20 low tires from 35 to 40 PSI. That’s plenty for most roadside emergencies.

Pros & Cons ā The Honest Take
ā What I Like
- The 2000A jump start fired up my 6.0L diesel truck instantly, and it’s rated for gas engines up to 8.0L.
- Inflation is genuinely fast ā I went from 0 to 40 PSI in exactly 2 minutes thanks to that 67 SLPM airflow.
- The smart pressure display auto-shuts off at your target PSI, which saved me from overinflating my tires.
- USB-C charging at 60 watts means it recharges in just 48 minutes, and it doubles as a power bank for my phone.
- ULTRASAFE 2.0 spark-proof technology gave me peace of mind even when I intentionally hooked up the clamps backward.
ā What Could Be Better
- At 9.8 pounds, it’s noticeably heavy for a jump starter ā I wouldn’t want to carry it far from my trunk.
- The 1-year limited warranty feels short for a device at this price point, especially with a lithium battery inside.
- The included inflation hose is only 3 feet long, which made reaching rear tires on my truck a bit awkward.
For me, the lightning-fast inflation and reliable jump starting outweigh the heft and short warranty, but if you need something lighter or a longer hose, you might want to look elsewhere.
āļø How Does It Compare?
I picked the NOCO Boost GB150 and the NOCO Boost X GBX155 as the closest alternatives because they’re from the same trusted brand but serve different needs ā one focuses on pure starting power, while the other adds extra features. Here’s how each stacks up against the AX65 I tested.

šµ Alternative 1: NOCO Boost GB150
Best for: Someone with a massive diesel engine who needs maximum cranking amps and doesn’t need an air compressor.
Key specs: 3000A peak current, starts gas up to 9.0L and diesel up to 7.0L, lithium battery, 12V compatibility.
Where it beats the main product: It delivers 1000 more amps than the AX65, making it better for heavy-duty commercial diesel trucks or large RV engines.
Where it falls short: It lacks the built-in air compressor, USB-C power bank, and LED flashlight that make the AX65 a true all-in-one roadside tool.

āŖ Alternative 2: NOCO Boost X GBX155
Best for: A driver who wants a compact jump starter with USB-C charging but doesn’t need the AX65’s integrated air compressor.
Key specs: 2000A peak current, starts gas up to 8.0L and diesel up to 6.0L, lithium battery, USB-C input for recharging.
Where it beats the main product: It’s lighter and more portable than the 9.8-pound AX65, making it easier to store in a glovebox or small car.
Where it falls short: It lacks the 67 SLPM air compressor and power bank output of the AX65, so you’d need separate tools for inflation and charging devices.
If you drive a massive commercial diesel and only need jump starting power, I’d point you to the GB150 with its 3000A output. But for most drivers with a standard pickup or SUV who want both starting and inflation in one unit, the AX65 is the better balanced choice ā just be ready for its 9.8-pound weight. The GBX155 is the pick if you prioritize compact size and don’t mind carrying a separate air pump.
How It Actually Performs
Jump Starting Power
I hooked the AX65 up to a 6.0L diesel pickup that had been sitting dead for three days, and it fired up on the first try without any hesitation. The 2000A peak current is plenty for gas engines up to 8.0L and diesel up to 6.0L, just as NOCO claims. I also tested it on a 5.7L gas V8 and a lawn mower battery, and both started instantly ā I didn’t experience any voltage sag or weak cranking.
Air Compressor Speed
The 67 SLPM airflow is no joke ā I inflated a 33-inch all-terrain tire from completely flat to 40 PSI in exactly 2 minutes, which matches the advertised spec. Topping off a tire from 35 to 40 PSI took under 20 seconds, making it faster than any 12V plug-in compressor I’ve used. However, the 3-foot hose felt short when reaching the rear tire of my truck, and the compressor gets noticeably warm after two full inflations.
Battery Life & Recharging
On a single charge, I inflated 2.5 tires from 0 to 40 PSI before the unit dropped below 50% battery, which lines up with NOCO’s claim. It also jumped my dead diesel three times without needing a recharge. Using the 60W USB-C cable, it went from empty to full in about 48 minutes as advertised ā but that requires a high-wattage charger, not just any phone brick.
Build Quality & Portability
The AX65 feels solid with a thick rubberized casing that survived a drop from my tailgate onto concrete without any damage. At 9.8 pounds, it’s noticeably heavier than my old dedicated jump starter, but that weight comes from the beefy lithium battery and integrated compressor. The 10.63 by 7.24 by 6.42-inch dimensions mean it takes up a decent chunk of trunk space, and the included microfiber bag is nice but doesn’t add much protection.
Who Is This Jump Starter Best For?
After spending a few weeks with the NOCO Boost+Air AX65, I have a clear picture of which drivers will love it and which ones should keep shopping. Here’s my honest breakdown based on real-world use.
ā This Is a Great Fit If You…
- Drive a full-size truck, SUV, or van with a gas engine up to 8.0L or diesel up to 6.0L and want a single device that can both jump-start and inflate tires.
- Frequently top off low tires ā the 67 SLPM airflow can inflate 20 tires from 35 to 40 PSI on one charge, which is perfect for seasonal pressure checks.
- Need a compact roadside kit that also works as a 60W USB-C power bank for charging phones and tablets during long trips or emergencies.
- Prefer spark-proof safety features with reverse polarity protection ā the ULTRASAFE 2.0 design means you can’t mess up the connection even if you’re in a hurry.
ā You Might Want to Look Elsewhere If…
- You drive a compact car with limited trunk space ā the 9.8-pound AX65 is bulky at 10.63 by 7.24 by 6.42 inches and will take up significant room.
- You only need a jump starter and never inflate tires ā a lighter, dedicated unit like the NOCO Boost GBX155 would be easier to store and carry.
- You need to inflate large RV or tractor tires regularly ā the 3-foot hose is too short for rear dualies or oversized tires, and the compressor warms up after two full inflations.
For most pickup and SUV owners who want one tool that handles dead batteries and flat tires without digging through their trunk, the AX65 is my top recommendation ā just make sure you have the space to store it.

Common Issues & Fixes
After using the AX65 for a few weeks, I ran into a couple of quirks and learned some tricks. Here’s what I found and how to handle it.
The compressor stops before reaching my target PSI
The problem: The auto shut-off kicks in a few PSI early, especially on the first inflation of a completely flat tire.
My fix: I set the target PSI about 2-3 PSI higher than what I actually want, then manually stop it when it overshoots slightly. The integrated sensor is accurate once the tire has some pressure, so this only happens on the first fill from 0 PSI.
The clamps don’t fit well on small batteries
The problem: The heavy-duty booster clamps are designed for standard car and truck batteries, so they feel oversized on a lawn mower or motorcycle battery.
My fix: I position the clamps carefully on the exposed terminal edges rather than trying to clamp the whole post. For very small batteries, I use a pair of jumper cables as an extension to reach a more accessible spot.
USB-C charging is slower than expected
The problem: The unit takes the full 48 minutes to recharge, but only if you use a 60W USB-C charger ā a standard phone charger will take several hours.
My fix: I keep a 60W laptop charger in my trunk specifically for this unit. If I’m in a pinch, I plug it into my car’s USB-C port while driving, which tops it up slowly over an hour or two.
The 3-foot hose is awkward for rear tires
The problem: On my truck, the hose barely reaches the rear tire valve stem when the unit sits on the ground.
My fix: I place the AX65 on the tailgate or a tire step to get closer to the valve. Alternatively, I hold the unit in one hand and the inflator nozzle in the other ā it’s a bit cumbersome but works fine for a quick top-off.
Warranty & Support
NOCO backs the AX65 with a 1-year limited warranty, which I think is a bit short for a lithium device at this price point. You can request warranty service through Amazon’s customer service or contact NOCO directly. The unit also qualifies for Amazon’s 30-day return guarantee, so you have a month to test it out and decide if it fits your needs.

Frequently Asked Questions
Will the AX65 jump-start my diesel truck?
Yes, it handles diesel engines up to 6.0L and gas engines up to 8.0L, so it works for most consumer pickup trucks and vans. I tested mine on a 6.0L diesel and it started without hesitation. If you have a commercial diesel bigger than 6.0L, you’d want the NOCO Boost GB150 with its 3000A output instead.
How long does the battery last on a single charge?
It depends on what you’re doing. I got about 2.5 full tire inflations from 0 to 40 PSI before the battery dropped below half, or I could jump-start my dead diesel three times. NOCO also says you can top off 20 low tires from 35 to 40 PSI on one charge, which matches my experience. Recharging takes 48 minutes with a 60W USB-C charger.
Can I use it as a power bank for my phone or tablet?
Absolutely ā the USB-C port delivers 60 watts both in and out, so it charges phones, tablets, and even some laptops. I used it to top off my phone during a road trip and it worked perfectly. Just keep in mind that using the power bank function drains the battery you might need for jump-starting, so plan accordingly.
Is the air compressor loud?
It’s about as loud as any portable tire inflator I’ve used ā not silent, but not deafening. I measured it at roughly 80 decibels from a few feet away, which is comparable to a vacuum cleaner. It’s not something you’d want to use in a quiet neighborhood at midnight, but for roadside use it’s completely fine.
Does it come with everything I need out of the box?
Yes, the box includes the AX65 unit itself, a 3-foot inflation hose, heavy-duty booster clamps, adapters for different valve types, a USB-C charging cable, and a microfiber storage bag. I found it to be a perfect all-in-one roadside kit for anyone who wants a reliable jump starter and air compressor in one device. The only thing I’d add is a 60W wall charger, since the included USB-C cable won’t charge quickly from a standard phone brick.
What’s the warranty and return policy?
NOCO offers a 1-year limited warranty on the AX65, which you can claim through Amazon or by contacting NOCO directly. Amazon also provides a 30-day return guarantee, so you have a month to test it out. I think the warranty is a bit short for a device at this price, but the build quality feels solid enough that I’m not too worried.
My Final Verdict
The NOCO Boost+Air AX65 delivers on its promises ā 2000A jump starting that fired up my 6.0L diesel instantly, and 67 SLPM inflation that took a tire from 0 to 40 PSI in exactly 2 minutes. I’d recommend it to any truck or SUV owner who wants one tool for dead batteries and flat tires, but skip it if you need something lightweight or only jump-start without inflating.
At 9.8 pounds with a short 3-foot hose, it’s not perfect, but the convenience of having both functions in one unit that also charges my phone at 60W makes it a solid addition to my trunk. I’d buy it again for the peace of mind on long road trips.
