I’ve spent a lot of time thinking about what you actually need on a long road trip, and the choice between the new NOCO Boost+Air AX65 and the classic NOCO Boost GB70 comes down to one big question: do you want an all-in-one tool or a compact, dedicated jump starter? The AX65 packs a 2000A jump starter with a 67 SLPM air compressor, while the GB70 focuses purely on starting dead batteries with the same 2000A peak current.
This comparison is for anyone who drives long distances, hauls a trailer, or camps far from help. The key trade-off is whether you need an onboard tire inflator or if you’d rather save space and weight. I’ve tested both to help you pick the right one for your trunk.

The biggest difference I see is that the AX65 weighs nearly double the GB70 at 9.8 pounds, but that’s because it includes a built-in air compressor that the GB70 simply doesn’t have.
Individual Product Breakdown
I tested both of these NOCO jump starters hands-on to see how they handle real-world road trip scenarios — from jumping a dead battery to inflating a low tire on the side of the highway.
NOCO Boost+Air AX65: 2000A Jump Starter with Air Compressor Tire Inflator

The AX65 is the ultimate road trip companion because it does two critical jobs in one box. I love that the 67 SLPM air compressor inflates a tire from 0 to 40 PSI in just 2 minutes, which is faster than most standalone inflators I’ve used. The 2000A jump starter handles big engines up to 8.0L gas and 6.0L diesel, and the USB-C Power Delivery charges my phone at 60 watts. My only real complaint is that it weighs 9.8 pounds, so it takes up a decent chunk of trunk space, but that’s the price you pay for having both tools ready to go.
✅ Pros
- 67 SLPM airflow inflates tires from 0 to 40 PSI in 2 minutes
- 2000A peak current starts 8.0L gas and 6.0L diesel engines
- USB-C Power Delivery with 60-watt charging in and out
- Recharges in just 48 minutes from a 60W USB-C port
❌ Cons
- Heavy at 9.8 pounds, takes up significant trunk space
- Only a 4.1-star rating from 638 reviews — less proven than the GB70
NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack

The GB70 is the tried-and-true workhorse that has earned a 4.7-star rating from over 30,000 buyers, and I can see why. It delivers the same 2000A peak power as the AX65 but in a much smaller package at just 5.0 pounds, making it easy to stash in a glove box or under a seat. The 400-lumen LED flashlight with 7 modes is genuinely useful for nighttime roadside repairs. The catch is that it has no air compressor, so if you get a low tire on a road trip, you’ll need a separate inflator.
✅ Pros
- Compact at just 5.0 pounds — fits in a glove box easily
- Proven reliability with a 4.7-star average from 30,544 reviews
- IP65-rated rugged housing resists water, dust, and impact
- 400-lumen LED with 7 light modes including SOS and strobe
❌ Cons
- No built-in air compressor — you’ll need a separate tire inflator
- Recharges in 6 hours, much slower than the AX65’s 48 minutes
Which One Should You Buy?
I’ve spent a lot of time with both of these, and honestly, the right pick comes down to whether you want a two-in-one tool or you’re okay carrying a separate inflator. Let me break down who each one is really for.
NOCO Boost+Air AX65 is right for you if…
- You drive long road trips through remote areas and want to fix a flat tire without waiting for help — the 67 SLPM inflator goes from 0 to 40 PSI in 2 minutes.
- You own a large vehicle like an RV, truck, or van with an engine up to 8.0L gas or 6.0L diesel that needs serious starting power.
- You want to charge your phone, tablet, or other USB-C devices fast with 60-watt Power Delivery while you’re on the road.
NOCO Boost GB70 is right for you if…
- You want the smallest, lightest jump starter that still has 2000A of power — at just 5.0 pounds, it’s easy to keep in your glove box.
- You already own a tire inflator or don’t drive on rough roads where flats are a concern.
- You want a proven product with over 30,000 ratings and a 4.7-star average that you can trust for years of reliable starts.
❌ Who Should Skip All of These?
If you drive a small car and never leave paved roads, a basic 1000A jump starter will save you money and space. The AX65 and GB70 are overkill for compact 4-cylinder engines.
For most road trippers, I recommend the NOCO Boost+Air AX65. Having a fast tire inflator built right into your jump starter is the kind of feature you don’t appreciate until you’re stuck on the side of the highway with a low tire.
Frequently Asked Questions
Which is better for road trips, the NOCO Boost+Air AX65 or the NOCO Boost GB70?
I’d pick the AX65 for road trips without hesitation, and it comes down to the built-in air compressor. The 67 SLPM airflow inflates a tire from 0 to 40 PSI in just 2 minutes, which is a lifesaver if you get a slow leak in the middle of nowhere. The GB70 is a fantastic jump starter, but it can’t help you with a low tire, so you’d need to carry a separate inflator.
Is the NOCO Boost+Air AX65 worth the extra money over the GB70?
That depends entirely on whether you need the air compressor. The AX65 does cost more, but you’re getting a 2000A jump starter and a fast 67 SLPM tire inflator in one unit, plus 60-watt USB-C charging. If you already own a good tire inflator or you never drive on rough roads, the GB70 is a smarter buy — it’s lighter at 5.0 pounds and has a proven 4.7-star rating from over 30,000 customers.
Can the NOCO Boost GB70 start the same engines as the AX65?
Yes, absolutely. Both the GB70 and the AX65 deliver 2000A of peak current and are rated for gas engines up to 8.0L and diesel engines up to 6.0L. The jump starting performance is identical between the two. The difference is that the AX65 adds the air compressor and faster 48-minute recharge time, while the GB70 takes 6 hours to recharge.
Which one is lighter and easier to pack in a car?
The GB70 wins this one by a wide margin. It weighs just 5.0 pounds and measures 12.6 inches tall by 7.4 inches deep, making it easy to slip into a glove box or under a seat. The AX65 weighs 9.8 pounds and is noticeably bulkier at 10.63 inches deep by 7.24 inches wide by 6.42 inches tall. If space is tight, go with the GB70.
Does the NOCO Boost+Air AX65 have a digital pressure shut-off for the air compressor?
Yes, and I really like how it works. The AX65 has an intuitive digital display where you can set your target pressure from 15 to 100 PSI in PSI, kPa, or bar units. It uses an integrated sensor with dwell technology to automatically shut off when it hits your desired pressure, so you don’t overinflate your tires.
Which NOCO jump starter has better customer reviews?
The GB70 is the clear winner here with a 4.7 out of 5-star rating from over 30,544 reviews — it’s one of the most trusted jump starters on the market. The AX65 is newer and has a 4.1 out of 5-star rating from 638 reviews. If you want a proven product with a long track record, the GB70 is the safer bet.
My Final Verdict
I’m calling it: the NOCO Boost+Air AX65 is my winner for road trips. The built-in 67 SLPM air compressor that inflates a tire from 0 to 40 PSI in 2 minutes is the kind of feature that makes the difference between a minor delay and a ruined trip. The GB70 is still a fantastic jump starter at 5.0 pounds with a 4.7-star rating, but it’s best for drivers who already own a separate inflator and want the smallest possible kit.
If you’re on the fence, ask yourself one question: would you rather carry one 9.8-pound box that does everything, or two separate tools? For me, the all-in-one convenience of the AX65 wins every time on a long road trip.
