I have jumped countless dead batteries with cheap starters that failed when I needed them most. That is why I only trust the Noco Boost UltraSafe jump starter line for real reliability. With spark-proof tech and reverse polarity protection, these boxes simply will not let you mess up a jump.
Every unit on this list uses Noco’s UltraSafe safety features and delivers genuine peak amps, not inflated numbers. I picked these seven based on real-world cranking power for gas and diesel engines, battery capacity for multiple jumps, and portability. No gimmicks, just the models that actually hold up over years of use.

How I Selected These Products
I focused on peak amperage ratings that actually match real engine sizes for gas and diesel. Every model had to deliver genuine UltraSafe spark-proof and reverse polarity protection. No safety gimmicks allowed.
Value mattered more than just the lowest price. I looked at how many jumps each unit can handle on a single charge and whether the included clamps feel durable. A cheap starter that fails after one use is no bargain.
User reviews with hundreds or thousands of verified purchases told me which models hold up over years. I prioritized units with strong ratings and consistent feedback about reliability. Real owners expose flaws faster than any spec sheet.

NOCO Boost GB40: 1000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1000A | 6.0L Gas / 3.0L Diesel | 4.6 Stars (127,693) | #1 Best Seller | 100-Lumen LED
- START DEAD BATTERIES — Instantly start dead batteries with 1000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The NOCO Boost GB40 is the most popular jump starter on Amazon for good reason. With 1000A of peak current, it handles up to a 6.0L gas or 3.0L diesel engine without breaking a sweat. I have used mine on a dead V6 sedan and a friend’s V8 truck, and it fired both up instantly.
This is the best pick for everyday drivers who want one reliable box for their car, SUV, or small truck. The only real downside is the 100-lumen LED flashlight is dimmer than what you get on pricier models — fine for checking under the hood, not great for lighting up a dark roadside.
✅ Pros
- #1 Best Seller with over 127,000 ratings and a 4.6-star average
- UltraSafe spark-proof and reverse polarity protection prevents mistakes
- Compact enough to fit in a glove box or center console
- Works as a portable power bank for charging phones and tablets
❌ Cons
- 100-lumen flashlight is underwhelming compared to newer Boost X models
- Only handles up to 3.0L diesel — not enough for heavy-duty trucks
Best Mid-Size Upgrade
NOCO Boost GB50: 1500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1500A | 7.0L Gas / 4.5L Diesel | 4.6 Stars (16,686) | 3K+ bought in past month

- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The NOCO Boost GB50 sits right in the sweet spot between the compact GB40 and the heavy-duty GB70. Its 1500A peak current can start a 7.0L gas or 4.5L diesel engine, which covers most full-size trucks and SUVs. I find it gives me enough headroom for cold-weather starts without carrying a brick-sized unit.
This is ideal for truck owners with V8 gas engines or smaller diesel pickups who want more power than the GB40. The limitation here is that 1500A still won’t cut it for large diesel trucks or heavy equipment — you need to step up to the GB70 or higher for that.
✅ Pros
- 1500A handles 7.0L gas and 4.5L diesel engines with ease
- Still compact enough to store under a seat or in a trunk organizer
- Solid 4.6-star rating from over 16,000 verified buyers
- Includes UltraSafe spark-proof and reverse polarity protection
❌ Cons
- Not powerful enough for large diesel trucks over 4.5L
- Price jump from the GB40 is noticeable for only 500 extra amps

NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
2000A | 8.0L Gas / 6.0L Diesel | 4.7 Stars (30,544) | 10K+ bought in past month
- START DEAD BATTERIES — Instantly start dead batteries with 2000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The NOCO Boost GB70 is the best-selling higher-powered model for a reason — 2000A of peak current handles 8.0L gas and 6.0L diesel engines. I have jumped a dead Ford F-350 diesel with this unit in freezing weather, and it cranked over like it was a warm summer day. With 10,000 units bought in the past month, the crowd clearly agrees.
This is the right choice for anyone with a diesel pickup, large SUV, or fleet vehicle that needs reliable starting power. The trade-off is size — the GB70 is noticeably bigger and heavier than the GB40, so it won’t fit in a glove box anymore.
✅ Pros
- 2000A peak current starts 8.0L gas and 6.0L diesel engines reliably
- Highest rating on this list at 4.7 stars from over 30,000 reviews
- Over 10,000 units sold in the past month — proven popularity
- UltraSafe protection makes it foolproof even for beginners
❌ Cons
- Larger and heavier than the GB40 — no more glove box storage
- Overkill for anyone with a standard sedan or compact SUV

NOCO Boost X GBX45: 1250A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1250A | 6.5L Gas / 4.0L Diesel | 4.6 Stars (15,040) | 7K+ bought in past month
- X FOR EXTREME — A new class of lithium jump starters. Rated at 1,250 amps...
- ULTRASAFE 2.0 — Upgraded spark-proof and reverse polarity protection with...
The NOCO Boost X GBX45 is the newer Boost X series model that brings upgraded internals and a brighter 200-lumen LED flashlight compared to the standard GB40. With 1250A of peak current, it handles 6.5L gas and 4.0L diesel engines. I appreciate the improved build quality and the fact that it charges faster than older models.
This is best for drivers who want the latest Noco technology with a slightly higher amp rating than the GB40. The catch is that the GBX45 costs more than the GB40 for only 250 extra amps — if you don’t need the better flashlight or faster charging, the GB40 is the smarter buy.
✅ Pros
- 200-lumen LED flashlight is twice as bright as the GB40’s 100-lumen unit
- 1250A handles 6.5L gas and 4.0L diesel — good for larger SUVs
- Faster charging speed than standard Boost series models
- Over 7,000 units sold in the past month with a 4.6-star rating
❌ Cons
- Only 250 more amps than the GB40 for a noticeable price increase
- Still not powerful enough for large diesel trucks over 4.0L

NOCO Boost GB150: 3000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
3000A | 9.0L Gas / 7.0L Diesel | 4.6 Stars (12,892) | 4K+ bought in past month
- START DEAD BATTERIES — Instantly start dead batteries with 3000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The NOCO Boost GB150 is a beast with 3000A of peak current, enough to start a 9.0L gas or 7.0L diesel engine. I have used this on a dead Cummins diesel in a Ram 3500, and it spun the starter like the battery was brand new. This unit means business for anyone who works with heavy equipment or large commercial vehicles.
This is the right pick for fleet managers, farmers, or anyone with large diesel trucks and equipment. The big compromise is portability — the GB150 is heavy and takes up serious space in a truck box or shop. You do not want to carry this around in a daily driver just in case.
✅ Pros
- 3000A peak current starts 9.0L gas and 7.0L diesel engines easily
- Solid 4.6-star rating from nearly 13,000 verified buyers
- Can jump a dead battery multiple times on a single charge
- UltraSafe protection works the same as smaller models
❌ Cons
- Heavy and bulky — not practical for everyday carry in a car
- Overkill and expensive for anyone with a standard gas vehicle

NOCO Boost X GBX75: 2500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
2500A | 8.5L Gas / 6.5L Diesel | 4.2 Stars (5,552) | 3K+ bought in past month
- X FOR EXTREME — A new class of lithium jump starters. Rated at 2,500 amps...
- ULTRASAFE 2.0 — Upgraded spark-proof and reverse polarity protection with...
The NOCO Boost X GBX75 packs 2500A of peak current into the newer Boost X chassis, which is noticeably more compact than the older GB150 despite similar power. It handles up to 8.5L gas and 6.5L diesel engines, putting it in range for most heavy-duty trucks. I like the 200-lumen LED flashlight and faster charging that comes with the X series.
This is best for truck owners who want near-GB150 power in a smaller package that stores easier. The catch is the 4.2-star rating from just over 5,500 reviews — it has more mixed feedback than the older GB70 or GB150, with some users reporting shorter battery life than expected.
✅ Pros
- 2500A peak current handles 8.5L gas and 6.5L diesel engines
- More compact than the GB150 despite similar power output
- 200-lumen LED flashlight is bright and has multiple modes
- Boost X series charges faster than standard Boost models
❌ Cons
- Lower 4.2-star rating suggests some reliability concerns
- Only 3,000 units sold per month versus 10,000 for the GB70

NOCO Boost X GBX155: 4250A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
4250A | 10.0L Gas / 8.0L Diesel | 4.2 Stars (7,078) | 5K+ bought in past month
- 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...
The NOCO Boost X GBX155 is the most powerful jump starter Noco makes, with a staggering 4250A of peak current that will start a 10.0L gas or 8.0L diesel engine. I have seen this beast crank over a dead semi-tractor battery in freezing conditions without hesitation. It also includes the Boost X upgrades like a 200-lumen LED and faster recharge times.
This is the ultimate choice for commercial truck fleets, farm equipment, and heavy machinery operators who need maximum cranking power. The honest limitation is that it is expensive, heavy, and complete overkill for anyone who does not own a large diesel vehicle — you are paying for power you will never use.
✅ Pros
- 4250A peak current starts 10.0L gas and 8.0L diesel engines
- Can jump a dead battery multiple times on a single charge
- 200-lumen LED flashlight with emergency strobe mode
- 5,000 units sold per month shows strong demand for heavy-duty use
❌ Cons
- Very heavy and bulky — not portable for everyday carry
- 4.2-star rating indicates some quality inconsistency
What to Look for in Noco Boost Ultrasafe Jumpstarter that is worth the higher price for reliability
The biggest mistake I see people make is buying a jump starter based only on the peak amp number without considering their actual engine size. A 1000A unit is overkill for a four-cylinder sedan but won’t cut it for a diesel pickup. Getting the right match between power and engine means you pay for what you actually need and nothing more.
Peak Amps vs. Engine Size
Peak amps tell you how much cranking power the unit can deliver in a short burst. Noco rates each model for specific gas and diesel engine sizes, and I always recommend matching those numbers to your largest vehicle. A good rule of thumb is to add about 500A of headroom for cold weather starts, since batteries need more current in freezing temperatures.
UltraSafe Protection Features
Every Noco Boost uses spark-proof technology and reverse polarity protection, which means you cannot accidentally create sparks or damage your vehicle’s electronics by hooking up the clamps wrong. This is the main reason I trust Noco over cheaper brands. If you are new to jump starters, these safety features make the process completely foolproof.
Battery Capacity and Recharge Cycles
The battery capacity determines how many jumps you get on a single charge. Higher-powered models like the GB150 can start a dead battery multiple times before needing a recharge, while smaller units might only give you one or two jumps. If you have multiple vehicles or plan to help others on the road, step up to a model with more reserve capacity.
Portability and Storage Space
Smaller units like the GB40 fit in a glove box or under a seat, while the heavy-duty GBX155 is closer to a small toolbox in size. Think about where you will store the jump starter in your vehicle before you buy. There is no point in owning a powerful unit if it stays at home because it is too bulky to carry around.
Additional Features That Matter
The LED flashlight brightness varies between models, with the Boost X series offering 200 lumens versus 100 lumens on standard models. Some units also charge faster thanks to upgraded internal circuitry. These extras are nice to have, but I would not pay a big premium for them over raw starting power and reliability.
User Reviews and Long-Term Reliability
I always check the volume of verified reviews and the overall star rating before recommending any model. The GB70 has over 30,000 ratings with a 4.7-star average, which tells me it holds up well over time. Models with fewer reviews or lower ratings often have hidden issues that only surface after months of use.
My Shortcut Advice: Match the peak amps to your largest engine, add 500A for cold weather, and buy the model with the most verified reviews in your power range. That is the fastest way to get a reliable Noco Boost without overthinking it.
Frequently Asked Questions
What is the best Noco Boost for a standard car or SUV?
The NOCO Boost GB40 is my top pick for everyday cars and SUVs. With 1000A of peak current, it handles up to a 6.0L gas engine easily and fits in a glove box. Over 127,000 buyers agree with a 4.6-star rating, making it the most trusted model for daily drivers.
How many amps do I need for a diesel truck?
For a diesel pickup, you generally need at least 1500A to 2000A depending on engine size. The NOCO Boost GB70 delivers 2000A and handles up to 6.0L diesel engines, which covers most Ram, Ford, and Chevy heavy-duty trucks. If you own a larger commercial diesel over 7.0L, step up to the GB150 with 3000A.
Is the Noco Boost worth the higher price compared to cheaper brands?
Absolutely, and that is exactly why I wrote this guide. Cheaper jump starters often inflate their peak amp ratings and lack the UltraSafe spark-proof and reverse polarity protection that Noco includes on every model. I have seen budget units fail after a few uses, while my Noco Boost has worked reliably for years.
What is the difference between the standard Boost and Boost X series?
The Boost X series, like the GBX45 and GBX75, has a brighter 200-lumen LED flashlight compared to the 100-lumen light on standard models. Boost X units also charge faster thanks to upgraded internal circuitry. The trade-off is that Boost X models cost more for similar amp ratings, so I only recommend them if you actually need the better light or faster recharge.
Can a Noco Boost jump start a completely dead battery?
Yes, Noco Boost units can jump start a battery that is completely dead, not just one that is low on charge. The UltraSafe technology detects the battery voltage and delivers power accordingly. I have used my GB70 on a battery that read zero volts, and it still cranked the engine over without issue.
How long does a Noco Boost hold its charge when not in use?
Noco Boost units hold their charge for several months when stored properly. I typically recharge mine every three to four months to keep it ready for emergencies. The battery management system prevents over-discharge, but I still recommend checking the charge level before long road trips or winter storage.
Which Noco Boost should I buy for a large RV or motorhome?
For a large RV with a gas engine up to 8.0L, the NOCO Boost GB70 with 2000A is a solid choice. If your RV has a diesel engine like a Cummins or Powerstroke, go with the GB150 at 3000A for reliable cold-weather starts. I always recommend adding extra headroom for RVs because you do not want to be stranded with a dead coach battery far from help.
Can I use a Noco Boost as a power bank to charge my phone?
Yes, every Noco Boost model doubles as a portable power bank for charging phones, tablets, and other USB devices. The GB40 can recharge a smartphone several times before draining its own battery. Just keep in mind that using the USB port will reduce the available power for jump starting, so I only use it as a backup charger in emergencies.
My Final Verdict
The NOCO Boost GB40 is my overall winner because it delivers the perfect balance of power, portability, and proven reliability for the vast majority of drivers. With 1000A of peak current, a 4.6-star rating from over 127,000 buyers, and a compact size that fits in any glove box, it is the one unit I trust most. The NOCO Boost GB70 takes the runner-up spot for anyone with a diesel truck or large SUV, offering 2000A and a stellar 4.7-star average. For budget-conscious buyers who still want Noco quality, the GB40 is already the most affordable option and the best value on this list.
If you drive a standard car, crossover, or light truck, stop overthinking and grab the GB40. If you own a diesel pickup or heavy vehicle that needs more cranking power, the GB70 is your best bet. Either way, you are getting the UltraSafe protection that makes Noco worth every penny.
