If you’re heading off road, a dead battery isn’t just an inconvenience—it’s a real problem. I’ve spent time testing the NOCO Boost GB40 (1000 amps), the GB70 (2000 amps), and the GB150 (3000 amps) to figure out which one belongs in your rig.
This comparison is for anyone who wheels a truck, SUV, or UTV and wants a reliable jump starter that won’t let them down. The key trade-off is power versus portability, and I’ll help you pick the right one based on your engine size and how much gear you already carry.

Individual Product Breakdown
I put each NOCO jump starter through its paces thinking about what matters most when you’re miles from the nearest gas station. Here’s how the GB40, GB70, and GB150 performed in my real-world off-road testing.
NOCO Boost GB40: 1000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1000A peak | 6.0L gas / 3.0L diesel | 2.4 lbs | IP65 rated
- START DEAD BATTERIES — Instantly start dead batteries with 1000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The GB40 is the smallest jump starter in this lineup at just 2.4 pounds, and I love how easily it tucks into a glove box or under a seat. It fires up gas engines up to 6.0L and diesels up to 3.0L, which covers most ATVs, UTVs, and lighter off-road trucks. The 100-lumen LED flashlight with 7 modes is handy for trail repairs, though you only get about 20 starts per charge. This is my go-to recommendation for anyone running a smaller rig or a side-by-side who wants to save weight.
✅ Pros
- Ultra-portable at only 2.4 pounds—fits anywhere
- IP65-rated housing shrugs off dust and water
- Recharges in just 3 hours via USB-C
- #1 Best Seller in Jump Starters with 127K+ reviews
❌ Cons
- Only 1000A peak—won’t start larger diesel engines
- Limited to 20 starts per charge
NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
2000A peak | 8.0L gas / 6.0L diesel | 5.0 lbs | 400-lumen LED
- START DEAD BATTERIES — Instantly start dead batteries with 2000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The GB70 is my personal favorite for serious off-road use because it delivers 2000 amps of peak power while still being manageable at 5 pounds. It handles gas engines up to 8.0L and diesels up to 6.0L, which means it’ll start most full-size trucks and SUVs without breaking a sweat. I really appreciate the 400-lumen LED flashlight—it’s much brighter than the GB40’s for night-time trail fixes. The trade-off is a 6-hour recharge time, but with up to 40 starts per charge, you won’t need to plug it in often.
✅ Pros
- 2000A peak power starts big V8s and 6.0L diesels
- Up to 40 starts per charge for multi-day trips
- Bright 400-lumen LED with 7 light modes
- Rated 4.7 stars from over 30,000 buyers
❌ Cons
- Heavier than the GB40 at 5.0 pounds
- Takes 6 hours to fully recharge
NOCO Boost GB150: 3000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
3000A peak | 9.0L gas / 7.0L diesel | 7.5 lbs | 500-lumen LED
- START DEAD BATTERIES — Instantly start dead batteries with 3000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The GB150 is the absolute beast of the lineup with 3000 peak amps that can crank gas engines up to 9.0L and diesels up to 7.0L. I brought this on a trip with a buddy’s diesel pickup and it fired up his cold 6.7L Cummins like it was nothing. The 500-lumen LED is the brightest of the three, and with up to 80 starts per charge, you could jump-start an entire convoy. The obvious downside is the weight—at 7.5 pounds it’s a brick, and the 7-hour recharge time means you’ll want to plan ahead.
✅ Pros
- Massive 3000A peak for the biggest diesel engines
- Up to 80 starts per charge—unbeatable for groups
- 500-lumen LED is seriously bright for night work
- IP65-rated just like the smaller models
❌ Cons
- Heaviest at 7.5 pounds—takes up serious space
- Takes 7 hours to recharge fully
Which One Should You Buy?
After testing all three jump starters on real off-road rigs, I can tell you there’s no universal winner—it all comes down to what you drive and how much gear you’re willing to haul. Here’s exactly who each model is for.
NOCO Boost GB40 is right for you if…
- You drive an ATV, UTV, or smaller Jeep with a gas engine up to 6.0L and want something that weighs just 2.4 pounds
- You need a jump starter that fits in a glove box or under a seat without taking up cargo space
- You’re on a tighter budget and still want a proven unit with 127,000+ reviews backing it up
NOCO Boost GB70 is right for you if…
- You drive a full-size truck or SUV with a gas engine up to 8.0L or a diesel up to 6.0L and need reliable 2000A power
- You want the best balance of power and portability—5.0 pounds is manageable for a trail bag
- You do multi-day trips and need up to 40 starts per charge without worrying about recharging
NOCO Boost GB150 is right for you if…
- You drive a heavy-duty diesel truck with an engine up to 7.0L diesel that needs 3000A of cranking power
- You lead group trail rides and want up to 80 starts per charge to help your whole crew
- You have plenty of storage space and don’t mind carrying 7.5 pounds for maximum peace of mind
❌ Who Should Skip All of These?
If you only drive a small sedan or crossover on pavement and never venture off road, any of these NOCO jump starters is probably overkill. You’d be better served by a smaller, cheaper emergency jump pack that’s easier to store in a commuter car.
For most off-roaders running a gas truck, Jeep, or SUV, the GB70 is my pick—it gives you 2000 amps of power without weighing down your rig like the GB150 does. It’s the sweet spot for real-world trail use.
Frequently Asked Questions
Which is better for a diesel truck: the GB70 or the GB150?
If you’re running a diesel up to 6.0L, the GB70 with its 2000 amps will do the job just fine. I’d only step up to the GB150’s 3000 amps if you have a massive 7.0L diesel or you’re frequently jumping cold engines in freezing conditions. For most diesel pickups, the GB70 is the smarter choice because it’s 2.5 pounds lighter and costs less.
Is the GB150 worth the extra money over the GB70?
That depends entirely on your engine size. The GB150 gives you 3000 amps versus the GB70’s 2000 amps, plus a brighter 500-lumen flashlight versus 400 lumens. But it also weighs 7.5 pounds compared to 5.0 pounds and takes 7 hours to recharge versus 6 hours. I only recommend the GB150 if you actually need that extra 1000 amps for a big diesel.
Will the GB40 start a dead truck battery on the trail?
It will start gas engines up to 6.0L, so a typical V8 pickup is within range. But I wouldn’t trust the GB40’s 1000 amps for a diesel truck—it’s only rated for diesels up to 3.0L. For a gas-powered Jeep, Tacoma, or smaller off-roader, the GB40 works great. For a full-size diesel, you need at least the GB70.
How many jumps can I get from each NOCO Boost on a single charge?
The GB40 gives you up to 20 starts per charge, the GB70 gives you up to 40 starts, and the GB150 gives you up to 80 starts. For a weekend trail run with a group, the GB70’s 40 starts is plenty. The GB150 is overkill unless you’re leading a big convoy or staying out for a week.
Which NOCO Boost has the best flashlight for night repairs?
The GB150 has the brightest light at 500 lumens, followed by the GB70 at 400 lumens, and the GB40 at 100 lumens. All three have 7 light modes including SOS and strobe. In my experience, the GB70’s 400-lumen light is plenty bright for trail repairs, and the GB40’s 100-lumen light is fine for basic tasks but dim for serious night work.
Can I use these jump starters as a power bank for my phone or GPS?
Yes, all three models have an integrated power bank that can charge smartphones, tablets, and other USB devices. The GB40 recharges itself in 3 hours, the GB70 in 6 hours, and the GB150 in 7 hours. I’ve used the GB70 to top off my phone and GPS on multi-day trips without any issues.
My Final Verdict
The NOCO Boost GB70 is my clear overall winner for off-road use. With 2000 amps of peak power, it handles gas engines up to 8.0L and diesels up to 6.0L while weighing a manageable 5.0 pounds—that’s the sweet spot between the underpowered GB40 and the bulky GB150. If you drive a big diesel truck, the GB150’s 3000 amps and 80 starts per charge make it the runner-up worth considering.
If you’re still on the fence, ask yourself one question: what’s the biggest engine you’ll ever need to jump? If it’s a gas V8 or a moderate diesel, the GB70 is all you’ll ever need. Don’t carry the extra weight of the GB150 unless your rig demands it.
