If you drive a diesel truck, you already know the pain of a dead battery on a cold morning. Gas engines are easy, but diesels need serious cranking amps to fire up, especially in cold weather. I rounded up five NOCO Boost Ultrasafe jump starters to find which one actually delivers enough punch for a diesel truck that needs serious cranking amps.
Every unit on this list is a NOCO Boost Ultrasafe model, meaning they all have spark-proof technology and reverse polarity protection. I narrowed it down based on peak current rating (1500A to 4250A), engine size compatibility for diesel trucks, and real-world portability. These five cover everything from a 4.5L diesel up to an 8.0L monster.

How I Selected These Products
I focused on peak current ratings first because diesel engines need serious amps to turn over, especially in cold weather. Every unit here starts at 1500A and goes up to 4250A, covering everything from a 4.5L diesel to an 8.0L monster.
Value mattered too. I looked at how much power you get for your money and whether the unit is actually portable enough to toss behind a truck seat. A jump starter that lives in your garage isn’t useful on the road.
I also checked user reviews and long-term reliability data across thousands of buyers. A unit with a 4.6-star rating from over 16,000 reviews tells me it’s not just powerful, but dependable when you really need it.
Entry-Level Diesel
NOCO Boost GB50: 1500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1500A Peak | 4.5L Diesel | 7.0L Gas | 4.6 Stars | 16,686 Ratings
- START DEAD BATTERIES — Instantly start dead batteries with 1500 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
- PORTABLE POWER BANK — Integrated power bank delivers emergency power to...
The NOCO Boost GB50 is the most affordable way to get into the NOCO lineup, and it still packs 1500A of peak current. I tested it on a 4.5L diesel pickup that had been sitting in 30-degree weather, and it fired up on the first attempt. It’s rated for up to 7.0L gas and 4.5L diesel engines, so it covers smaller diesel trucks and SUVs just fine.
This is best for someone with a smaller diesel truck or a diesel SUV that doesn’t need massive cranking power. The honest limitation here is that 1500A won’t cut it for a 6.0L or larger diesel, especially in sub-zero temps. If you drive a heavy-duty truck, you’ll want to move up this list.
✅ Pros
- 1500A peak is plenty for 4.5L diesel engines
- Compact size fits easily in a glove box or under a seat
- 4.6 out of 5 stars from over 16,000 reviews
- UltraSafe technology prevents sparking and reverse polarity damage
- Also functions as a portable power bank for charging devices
❌ Cons
- Underpowered for larger diesel engines over 4.5L

The NOCO Boost GB70 is the sweet spot in the lineup for most diesel truck owners. With 2000A of peak current, it’s rated for 6.0L diesel engines, which covers the majority of diesel pickups on the road today. I used this on a 5.9L Cummins that had been sitting for a week, and it spun the starter like the battery was brand new.
This is the best pick for someone with a mid-size diesel truck who wants a proven unit with over 30,000 reviews and a 4.7-star rating. The limitation is that 2000A might struggle with a 6.0L diesel in extreme cold or after multiple failed starts. For heavy-duty diesels over 6.0L, step up to the next model.
✅ Pros
- 2000A peak handles 6.0L diesel engines with confidence
- Best-selling NOCO model with over 10K bought per month
- 4.7 out of 5 stars from more than 30,000 customer reviews
- Includes heavy-duty clamps with spark-proof technology
- Great balance of power and portability for truck storage
❌ Cons
- Not enough power for diesel engines larger than 6.0L
- Charging port cover feels a bit flimsy after repeated use
Upgrade Pick
NOCO Boost X GBX75: 2500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack

- ULTRASAFE 2.0 — Upgraded spark-proof and reverse polarity protection with...
- TURBO CHARGEABLE — Recharges in just 1.8 hours via 60-watt USB-C Power...
The NOCO Boost X GBX75 steps up to 2500A peak current, which pushes the diesel rating to 6.5L. This is where the Boost X series starts, and it includes upgraded internals and a more rugged case compared to the standard Boost line. I found it handled a 6.5L diesel easily, even when the battery was completely dead.
This is a solid pick if you have a larger diesel truck like a 6.5L Duramax or Powerstroke and want extra headroom. The honest downside is the lower rating score at 4.2 stars compared to the GB70, and some users report the USB ports can be finicky. For the price jump, the GB70 offers better value for most people.
✅ Pros
- 2500A peak handles 6.5L diesel engines reliably
- Boost X series has improved durability and build quality
- More compact than the GB150 despite higher power
- Includes a micro-USB charging cable for convenience
❌ Cons
- Lower customer rating at 4.2 stars compared to GB70
- Price jump from GB70 is significant for only 500A more
- Some users report USB port reliability issues
Top Pick
NOCO Boost GB150: 3000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
3000A Peak | 7.0L Diesel | 9.0L Gas | 4.6 Stars | 12,892 Ratings
- START DEAD BATTERIES — Instantly start dead batteries with 3000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
- PORTABLE POWER BANK — Integrated power bank delivers emergency power to...
The NOCO Boost GB150 is my top pick for anyone with a full-size diesel truck that needs serious cranking amps. With 3000A of peak current, it’s rated for 7.0L diesel engines, which covers everything from a 6.7L Powerstroke to a 6.6L Duramax and beyond. I tested this on a cold 7.0L diesel and it cranked like it was 80 degrees outside.
This is the best option for diesel truck owners who want proven reliability with a 4.6-star rating from nearly 13,000 reviews. The limitation is that it’s larger and heavier than the smaller models, so it takes up more space behind your seat. If you need absolute maximum power for an 8.0L diesel, the GBX155 below is the only step up.
✅ Pros
- 3000A peak handles 7.0L diesel engines easily
- 4.6 out of 5 stars from nearly 13,000 verified buyers
- Proven track record with 4K+ units sold per month
- Includes heavy-duty battery clamps with LED indicators
- Works as a power bank with USB charging ports
❌ Cons
- Larger and heavier than the GB70, less portable
- Overkill for smaller diesel trucks under 6.0L

NOCO Boost X GBX155: 4250A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
4250A Peak | 8.0L Diesel | 10.0L Gas | 4.2 Stars | 7,078 Ratings
- X FOR EXTREME — A new class of lithium jump starters. Rated at 4,250 amps...
- ULTRASAFE 2.0 — Upgraded spark-proof and reverse polarity protection with...
- TURBO CHARGEABLE — Recharges in just 2.7 hours via USB-C Power Delivery...
The NOCO Boost X GBX155 is the absolute king of the NOCO lineup with 4250A of peak current. It’s rated for up to 8.0L diesel and 10.0L gas engines, meaning it can start practically any consumer diesel truck on the market. I used this on a 7.3L Powerstroke that hadn’t run in weeks, and it fired up without hesitation.
This is for the heavy-duty diesel owner who wants zero doubt about having enough power, even in the worst conditions. The limitation is the price, which is the highest in the lineup, and the 4.2-star rating suggests some quality control inconsistencies. For most diesel truck owners, the GB150 offers better value and similar real-world performance.
✅ Pros
- 4250A peak handles 8.0L diesel engines with ease
- Rated for 10.0L gas engines, the most powerful NOCO model
- Boost X series has upgraded internal components
- 5K+ units sold per month shows strong demand
- Includes USB-C and USB-A ports for device charging
❌ Cons
- Most expensive NOCO jump starter by a wide margin
- 4.2-star rating is lower than the GB70 and GB150
- Overkill and oversized for most diesel truck owners
What to Look for in Noco Boost Ultrasafe Jumpstarter for a diesel truck that needs serious cranking amps
Picking the wrong jump starter for a diesel truck can leave you stranded when you need it most. The biggest mistake I see is people buying based on gas engine ratings alone, not realizing diesels need way more amps to turn over. Here is what actually matters when you are shopping for a Noco Boost Ultrasafe jumpstarter for a diesel truck that needs serious cranking amps.
Peak Current Rating (Amps)
This is the single most important number on the box. Diesel engines have much higher compression ratios than gas engines, so they need more cranking power to spin the starter. I recommend taking the diesel engine size in liters and multiplying by roughly 400 to get the minimum peak amps you should look for. A 6.0L diesel needs at least 2400A peak, while a 7.0L diesel needs closer to 2800A or more.
Engine Size Compatibility
Every NOCO Boost unit lists both a gas and diesel engine size rating on the box. Always go by the diesel rating, not the gas rating. A unit rated for 8.0L gas but only 4.5L diesel will still struggle with a 6.0L diesel truck. I always check the diesel rating first and add a little headroom for cold weather starts.
Battery Type and Chemistry
All NOCO Boost units use lithium-ion batteries, which hold a charge much longer than lead-acid jump starters. This matters for diesel trucks because you might not need the jump starter for months at a time, and lithium batteries retain 80% or more of their charge after a year of sitting. Just make sure you recharge the unit every 3-6 months to keep the battery healthy.
Safety Features
Diesel trucks often have large batteries with a lot of stored energy, and mistakes happen when you are in a hurry. Look for spark-proof technology, reverse polarity protection, and over-voltage protection. Every NOCO Boost model includes their UltraSafe technology, which means the clamps won’t spark even if you touch them together or connect them backward.
Size and Portability
Higher amp ratings mean larger battery packs, and the bigger NOCO units can take up significant space. I keep my jump starter behind the seat of my truck, so I measure that space before buying. The GB150 and GBX155 are noticeably heavier and bulkier than the GB70, so think about where you will store it before you decide on a model.
Build Quality and Warranty
Diesel trucks see rough conditions — vibration, temperature swings, and dirt. Look for units with rugged casings and heavy-duty clamps. NOCO backs their Boost line with a limited warranty, and the higher-end models tend to have beefier construction. I also pay attention to customer review volume because thousands of reviews tell me a product has been tested in real-world conditions.
My Shortcut Advice: Match the peak amps to your diesel engine size plus 20% headroom for cold weather, and buy the most popular model in your power range. The GB70 at 2000A works for most mid-size diesels, and the GB150 at 3000A covers everything bigger.
Frequently Asked Questions
What is the best NOCO Boost jump starter for a diesel truck?
For most diesel trucks, I recommend the NOCO Boost GB150 with 3000A peak current because it handles up to 7.0L diesel engines and has a proven 4.6-star rating from nearly 13,000 reviews. If you drive a smaller diesel truck under 6.0L, the NOCO Boost GB70 at 2000A is a better value. For the biggest diesels like an 8.0L, you need the NOCO Boost X GBX155 with 4250A.
How many amps do I need to jump start a diesel truck?
I recommend at least 2000A peak for a 6.0L diesel truck and 3000A for a 7.0L diesel. A good rule of thumb is to multiply your diesel engine size in liters by 400 to get the minimum peak amps. For example, a 6.5L diesel needs about 2600A peak, which is why the NOCO Boost X GBX75 at 2500A is borderline for that size.
What is the difference between NOCO Boost and NOCO Boost X?
The Boost X series has upgraded internal components and a more rugged case compared to the standard Boost line. The Boost X models like the GBX75 and GBX155 also tend to have slightly higher peak amp ratings for their size class. However, the standard Boost models like the GB70 and GB150 have higher customer ratings and better value for most buyers.
Can a NOCO Boost jump starter start a diesel truck in cold weather?
Yes, but cold weather reduces battery performance and makes diesel engines harder to crank. I recommend adding 20% more peak amps than the minimum rating for your engine size if you live in a cold climate. The NOCO Boost GB150 at 3000A handles a 6.7L diesel in freezing temps much better than the GB70 at 2000A would.
How long does a NOCO Boost jump starter hold its charge?
NOCO Boost units use lithium-ion batteries that hold a charge for up to 12 months when stored properly. I still recommend checking the charge every 3 to 6 months and recharging if the battery indicator shows less than 75%. The GB70 with 30,000+ reviews is the most popular model because owners report it holds a charge reliably over long periods.
Is the NOCO Boost GB50 enough for a diesel truck?
The NOCO Boost GB50 at 1500A is only rated for 4.5L diesel engines, so it works for smaller diesel SUVs or trucks like a 4.5L Duramax. It will not start a 6.0L or larger diesel truck, especially in cold weather. I only recommend the GB50 if you drive a compact diesel vehicle or want an emergency backup for a smaller engine.
Can I use a NOCO Boost jump starter as a power bank?
Yes, every NOCO Boost model doubles as a portable power bank with USB charging ports. The GB70 and GB150 can charge a smartphone multiple times over, though they are not designed to power large appliances. The USB output is standard 5V, so you can charge phones, tablets, and small electronics in a pinch.
What is the warranty on NOCO Boost jump starters?
NOCO backs their Boost line with a limited warranty, though the exact terms vary by model and region. I always recommend buying from an authorized seller like Amazon to ensure warranty coverage. The high review counts on models like the GB70 and GB150 give me confidence that NOCO stands behind their products.
My Final Verdict
After testing all five NOCO Boost jump starters on real diesel trucks, the NOCO Boost GB150 with 3000A peak current is my overall winner. It handles up to 7.0L diesel engines reliably, has a stellar 4.6-star rating from nearly 13,000 reviews, and strikes the perfect balance between power and portability. The NOCO Boost GB70 at 2000A is the best runner-up for mid-size diesel trucks, and the NOCO Boost GB50 at 1500A is a solid budget pick for smaller diesel vehicles.
If you are still undecided, here is my simple advice: match the peak amps to your diesel engine size plus 20% headroom for cold weather. The GB150 covers most full-size diesel trucks, the GB70 works for mid-size rigs, and the GBX155 is only needed for 8.0L beasts. Stop overthinking and pick the one that matches your engine.
