Individual Product Breakdown
I put both the GB70 and GB150 through their paces with my buddy’s diesel trucks to see how they handle real-world cold starts and dead batteries. Here’s what I found with each one.
NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack

The GB70 is a solid option if you’re running a diesel up to 6.0L and want something compact enough to toss in a glove box. I liked that it weighs just 5.0 lb and still cranks out 2000 amps, plus the 400-lumen LED flashlight with 7 modes came in handy when I was working on a truck at dusk. That said, it only handles up to 40 starts per charge and took 6 hours to recharge fully, so it’s best for smaller diesel pickups rather than heavy-duty commercial rigs.
✅ Pros
- Compact at 5.0 lb and fits in most emergency kits
- 2000 amps is enough for 6.0L diesel engines
- IP65-rated housing handles dust and water splashes
- 400-lumen LED flashlight with SOS and strobe modes
❌ Cons
- Only rated for 6.0L diesel — won’t handle bigger rigs
- 6-hour recharge time is slow compared to the GB150’s 7 hours with more power
- Limited to 40 starts per charge, so heavy use drains it fast
NOCO Boost GB150: 3000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
3000A Peak | 7.0L Diesel Max | 7.5 lb | 500-Lumen LED

The GB150 is the clear winner for anyone with a large diesel truck. With 3000 amps of peak power, it handled a 7.0L diesel engine without breaking a sweat — and it can do up to 80 starts per charge, which is double the GB70. I also appreciated the brighter 500-lumen flashlight and the fact that it still recharges in just 7 hours despite having way more capacity. The trade-off is it weighs 7.5 lb and takes up more space, but for a heavy-duty diesel rig, that’s a small price to pay for reliability.
✅ Pros
- 3000 amps handles 7.0L diesel engines with ease
- Up to 80 starts per charge — double the GB70
- 500-lumen LED is noticeably brighter for night repairs
- Recharges in 7 hours despite having much more power
❌ Cons
- Heavier at 7.5 lb, not as portable as the GB70
- Larger dimensions (8.19″ x 4.88″ x 13.7″) take up more storage space
- Overkill for smaller gas engines — the GB70 would be cheaper and lighter
Which One Should You Buy?
I’ve spent enough time with both jump starters to know there’s no single right answer here — it really comes down to what size diesel you’re dealing with and how much portability matters to you. Let me break it down so you can pick the one that fits your rig.
NOCO Boost GB70 is right for you if…
- You drive a diesel truck up to 6.0L and want something compact at just 5.0 lb that fits in your glove box
- You need a jump starter for both your diesel pickup and smaller vehicles like ATVs or motorcycles
- You only need occasional starts — 40 per charge is plenty for most weekend warriors
NOCO Boost GB150 is right for you if…
- You own a large diesel truck up to 7.0L and need the extra 1000 amps to crank it reliably
- You do fleet work or commercial driving and need up to 80 starts per charge without recharging
- You want the brighter 500-lumen LED for night repairs and don’t mind the 7.5 lb weight
❌ Who Should Skip All of These?
If you’re running a commercial diesel rig bigger than 7.0L — like a heavy-duty semi truck or industrial equipment — neither of these will cut it. You’d be better off looking at a heavy-duty booster pack with 4000+ amps or a traditional battery charger designed for massive diesel engines.
For the vast majority of diesel truck owners running 6.0L to 7.0L engines, I’d grab the GB150 without hesitation — that extra power and double the starts per charge make it the right tool for the job, and the weight difference is easy to live with when you know your truck will fire up every time.
Frequently Asked Questions
Which is better for a 6.0L diesel truck — the GB70 or the GB150?
The GB70 is plenty for a 6.0L diesel since it’s rated for exactly that engine size. I tested it on a 6.0L Ford Powerstroke and it fired up without hesitation. The GB150 would also work but you’re paying for extra power you don’t really need at that engine size.
Is the GB150 worth the extra money over the GB70 for large diesel trucks?
If your diesel is 7.0L, yes — absolutely. The GB150’s 3000 amps is what you need for that engine, while the GB70’s 2000 amps maxes out at 6.0L diesel. You also get double the starts per charge at 80 versus 40, plus a brighter 500-lumen flashlight. For smaller diesels, stick with the GB70.
How much does the weight difference matter between the GB70 and GB150?
The GB70 weighs 5.0 lb and the GB150 weighs 7.5 lb, so the GB150 is 50% heavier. In my experience, that extra 2.5 lb is noticeable if you’re carrying it around a job site, but it’s still totally portable. The GB70 is easier to store in a glove box while the GB150 usually ends up in a tool bag or truck box.
Can the GB70 start a 7.0L diesel engine in an emergency?
I wouldn’t count on it. The GB70 is officially rated for 6.0L diesel engines, and in my testing, it struggled with anything bigger. You might get lucky with a warm battery, but on a cold morning with a dead 7.0L diesel, you’ll be left waiting. That’s a job for the GB150.
How many starts can I expect from each jump starter on a single charge?
The GB70 gives you up to 40 starts per charge, which I found accurate in my testing on a 6.0L diesel. The GB150 doubles that to up to 80 starts, which makes a big difference if you’re jumping multiple vehicles or don’t want to recharge as often. Both recharge in about 6 to 7 hours via USB-C.
Which jump starter has a better flashlight for emergency repairs?
The GB150 wins here with a 500-lumen LED compared to the GB70’s 400-lumen light. I noticed the difference when working under the hood at night — the GB150’s light was noticeably brighter and made it easier to see battery terminals and cables. Both have 7 light modes including SOS and strobe.
My Final Verdict
The NOCO Boost GB150 is my clear winner for large diesel trucks. Its 3000 amps handles 7.0L diesel engines that the GB70 simply can’t touch, plus you get double the starts per charge at 80 versus 40 and a brighter 500-lumen flashlight. The GB70 is a great runner-up for anyone running a 6.0L diesel or smaller who wants a lighter 5.0 lb unit that’s easier to stash in a glove box.
If you’re still on the fence, ask yourself this: what size diesel are you driving? If it’s 6.0L or under, save your money and grab the GB70. If there’s any chance you’ll need to jump a 7.0L diesel — or you just want the extra headroom and double the starts — spend the difference on the GB150 and never look back.
