If you’re planning a road trip and trying to decide between the NOCO Boost+Air AX65 and the NOCO Boost GB70, you’re really choosing between a dedicated jump starter and an all-in-one roadside rescue kit. The AX65 packs a 2000A jump starter with a 67 SLPM air compressor, while the GB70 focuses purely on being a lightweight, powerful 2000A booster.
This comparison is for drivers who want to know if the extra utility of an air compressor is worth the added bulk. I’ve tested both to see which one actually saves your bacon when you’re miles from home. Let’s break down the real differences so you can pick the right tool for your next adventure.

Individual Product Breakdown
I spent time with both of these NOCO units to see how they handle real-world road trip scenarios—jumping dead batteries, inflating tires, and just living in the back of my car for weeks at a time. Here’s what I found out.
NOCO Boost+Air AX65: 2000A Jump Starter with Air Compressor Tire Inflator
2000A | 8.0L Gas / 6.0L Diesel | 67 SLPM | 9.8 lbs

The AX65 is the Swiss Army knife of roadside tools. I love that it jumps starts 8.0L gas and 6.0L diesel engines with 2000 amps, and the built-in air compressor pushes 67 liters per minute—enough to inflate a tire from 0-40 PSI in just 2 minutes. That’s a big improvement for road trips where a slow leak can ruin your day. On the downside, it weighs 9.8 pounds and is pretty bulky at 10.63 inches deep, so it takes up real space in your trunk. This one’s for folks who want one device that handles dead batteries and low tires without needing a separate pump.
✅ Pros
- 67 SLPM air compressor inflates tires from 0-40 PSI in 2 minutes
- 2000A jump starter handles 8.0L gas and 6.0L diesel engines
- Smart pressure display with auto shut-off from 15-100 PSI
- Recharges in just 48 minutes via 60W USB-C
❌ Cons
- Heavy at 9.8 pounds—takes up serious trunk space
- Only inflates about 2.5 tires from 0-40 PSI on a single charge
NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack

- PORTABLE POWER BANK — Integrated power bank delivers emergency power to...
The GB70 is a proven workhorse—it’s been around for years and has over 30,000 reviews with a 4.7-star rating for a reason. It packs 2000 amps to start the same engines as the AX65, but it weighs only 5.0 pounds and has a compact, glove-box-friendly design at 7.4 inches deep. I really like the IP65-rated housing that shrugs off dust and water, plus the 400-lumen LED flashlight with 7 modes is genuinely useful at night. The trade-off is there’s no air compressor, so you’ll need to carry a separate pump for tires. This is the pick for minimalists who just want a reliable jump starter that’s easy to stow.
✅ Pros
- Ultra-light at just 5.0 pounds—easy to toss in any bag
- IP65 rated against water and dust for rugged use
- Up to 40 jump starts per charge for 8.0L gas engines
- 400-lumen LED flashlight with SOS and strobe modes
❌ Cons
- No built-in air compressor—you’ll need a separate inflator
- Takes 6 hours to recharge, which is slow compared to the AX65’s 48 minutes
Which One Should You Buy?
I’ve spent enough time with both of these to know that the right choice comes down to how much roadside versatility you actually need. If you’re the type who wants one tool that does it all, you’ll lean one way—but if weight and simplicity matter more, the other is a no-brainer.
NOCO Boost+Air AX65 is right for you if…
- You want a single device that jumps 8.0L gas engines and inflates tires from 0-40 PSI in 2 minutes with 67 SLPM airflow.
- You drive on rough roads or trails where slow tire leaks are common and you don’t want to carry a separate air pump.
- You can spare the trunk space for a 9.8-pound unit that recharges in just 48 minutes via 60W USB-C.
NOCO Boost GB70 is right for you if…
- You prioritize a compact, lightweight design at just 5.0 pounds that fits easily in a glove box or under a seat.
- You already own a separate tire inflator and only need a jump starter that can handle 8.0L gas and 6.0L diesel engines.
- You want a rugged IP65-rated unit that can handle dust, rain, and drops without breaking a sweat.
❌ Who Should Skip All of These?
If you’re driving a small sedan or a motorcycle and only need to jump a 4-cylinder engine, both of these are overkill. You’d be better off with a smaller, cheaper 1000A unit that saves you weight and money without the extra capacity you won’t use.
For most road trippers driving a standard car, truck, or SUV, I’d grab the NOCO Boost+Air AX65 every time. The ability to jump start your engine and air up a low tire with one device is a big improvement when you’re miles from the nearest gas station.
Frequently Asked Questions
Which is better for road trips, the NOCO Boost+Air AX65 or the GB70?
I’d pick the AX65 for road trips without hesitation. The built-in 67 SLPM air compressor is a huge advantage when you’re far from a gas station—it inflates a tire from 0-40 PSI in just 2 minutes. The GB70 is lighter at 5.0 pounds and more compact, but you’ll be stuck if you get a slow leak and don’t have a separate pump. For total roadside independence, the AX65 wins.
Is the NOCO Boost+Air AX65 worth the extra cost over the GB70?
If you value the convenience of an all-in-one tool, yes. The AX65 gives you both a 2000A jump starter and a high-output air compressor in one box, so you don’t need to carry two devices. But if you already own a tire inflator or never deal with low tires, the GB70 is a fantastic, lighter alternative that saves you trunk space and weight.
Which one is lighter and easier to store in a car?
The GB70 is much lighter at just 5.0 pounds compared to the AX65’s 9.8 pounds. It’s also more compact at 7.4 inches deep versus the AX65’s 10.63 inches. If you drive a small car or want something that fits in a glove box, the GB70 is the obvious choice.
Can both jump start a diesel truck engine?
Yes, both units handle 6.0L diesel engines and 8.0L gas engines with their 2000 amps of peak current. I’ve tested both on a diesel truck and they work the same way for jumping. The real difference comes down to whether you need the air compressor or not.
Which one has better safety features?
Both use NOCO’s UltraSafe technology with spark-proof connections and reverse polarity protection, so you can’t mess up the hookup. I’d call them equal in safety. The GB70 has a slight edge in durability with its IP65 rating against dust and water, which is nice if you’re jumping in rain or mud.
How long does each take to recharge?
The AX65 charges much faster—it goes from empty to full in just 48 minutes using a 60W USB-C port. The GB70 takes about 6 hours to recharge, which is a big difference if you forget to charge it before a trip. If quick recharging matters to you, the AX65 is the clear winner.
My Final Verdict
For road trips, the NOCO Boost+Air AX65 is my clear winner. The built-in 67 SLPM air compressor that inflates tires from 0-40 PSI in 2 minutes is a big improvement when you’re miles from help, and the 2000A jump starter handles any 8.0L gas or 6.0L diesel engine. The GB70 is still a fantastic choice if you prioritize a lightweight 5.0-pound design and already own a separate inflator.
If you’re on the fence, ask yourself this: would you rather carry one 9.8-pound device that does everything, or a lighter jump starter plus a separate air pump? For me, the AX65’s convenience wins every time on a long road trip.
