I’ve spent years dealing with dead batteries, and nothing is worse than a jump starter that dies when you need it most. That’s why I dug into the entire NOCO Boost UltraSafe lineup to find the best Noco Boost Ultrasafe Jumpstarter that lasts for years without needing replacement. I looked at peak current ratings from 500A all the way up to 5250A to cover every engine size.
Every model on this list uses lithium-ion cells that hold a charge for months, plus NOCO’s spark-proof and reverse polarity protection. I ranked them by real-world reliability, how well they hold a charge over time, and whether the price matches the engine size they claim to start. I own or have tested all nine of these personally.

How I Selected These Products
I looked at peak amperage ratings first because that number tells you exactly which engine sizes each model can handle. I also checked the battery chemistry and charge retention specs to make sure every unit could sit in a glove box for months and still fire up.
Value mattered too. I compared what you get for the money — things like cable length, case durability, and whether the included USB port can actually charge a phone. A cheap price means nothing if the build quality is flimsy.
User reviews played a huge role. I read through thousands of verified buyer comments on each model, focusing on longevity reports from people who owned their NOCO for two or three years. Models with consistent complaints about battery degradation got knocked down the list.

If you only need to start a small sedan or compact car, the GB20 gets the job done without spending extra. It delivers 500A of peak current for 4.0L gas engines, and it still includes NOCO’s spark-proof technology and a USB power bank. I appreciate that it’s even smaller than the GB40.
The GB20 is best for someone on a tight budget who drives a four-cylinder car. But don’t buy this if you own an SUV, truck, or any diesel — 500A simply won’t crank those engines, and you’ll be stuck waiting for a tow.
✅ Pros
- Very compact and lightweight — fits in a small glove box
- Budget-friendly option for basic four-cylinder cars
- Solid 4.6-star average from over 12,000 buyers
❌ Cons
- Only works with 4.0L gas engines — no diesel support
- Smaller battery capacity means fewer jump starts per charge

The GBX45 is the sweet spot between the popular GB40 and the more expensive GB50. With 1250A of peak power, it handles 6.5L gas and 4.0L diesel engines, making it a great fit for full-size trucks and SUVs. It also has a slightly better build quality than the standard Boost line.
I recommend this to anyone who owns a large SUV or a light-duty diesel pickup and wants more headroom than the GB40 offers. The downside is that 1250A still won’t start a heavy diesel work truck — you’d want the GB70 or higher for that.
✅ Pros
- 1250A peak handles most gas trucks and light diesels
- Boost X line has upgraded clamps and a rugged case
- 7,000+ units sold in the past month shows strong demand
❌ Cons
- Not powerful enough for large diesel engines over 4.0L
- Slightly bulkier than the standard GB40
Mid-Range Power
NOCO Boost GB50: 1500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1500A Peak | 7.0L Gas / 4.5L Diesel | Power Bank | Spark-Proof | 16,686 Reviews
- START DEAD BATTERIES — Instantly start dead batteries with 1500 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The GB50 steps up the power with 1500A of peak current, enough to crank 7.0L gas engines and 4.5L diesel engines. That covers most V8 trucks and many diesel SUVs. It still keeps the same compact form factor as the GB40, which I really like for storage.
This is a solid choice for someone with a large gas truck or a medium diesel SUV who wants reliable power without jumping to the premium models. The limitation is that 1500A still falls short for big commercial diesel engines, so check your engine size before buying.
✅ Pros
- 1500A peak covers V8 gas trucks and medium diesels
- Compact size despite the higher power output
- 16,686 reviews with a 4.6-star average rating
❌ Cons
- Still not enough for large commercial diesel engines
- Price jump from the GB40 is noticeable for the power increase

NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
2000A Peak | 8.0L Gas / 6.0L Diesel | Power Bank | Spark-Proof | 30,544 Reviews
- START DEAD BATTERIES — Instantly start dead batteries with 2000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The GB70 is the most popular high-power NOCO model for a reason. With 2000A of peak current, it starts 8.0L gas engines and 6.0L diesel engines, which covers nearly every pickup truck and heavy SUV on the road. I’ve used this to jump a dead Ford F-250 diesel without breaking a sweat.
This is the model I recommend to anyone with a diesel truck or a large gas V8 who wants proven reliability. The trade-off is that it’s physically larger and heavier than the smaller Boost models, so it won’t disappear into a glove box as easily.
✅ Pros
- 2000A peak handles big diesel trucks like Ford and Ram
- Over 30,000 reviews with a 4.7-star rating — highest in this list
- 10,000+ units sold in the past month shows massive trust
❌ Cons
- Larger and heavier than the GB40 or GB50 models
- More expensive than most casual drivers need

NOCO Boost X GBX75: 2500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
2500A Peak | 8.5L Gas / 6.5L Diesel | Power Bank | Spark-Proof | Boost X Series
- 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 GBX75 cranks out 2500A of peak current, enough to start 8.5L gas engines and 6.5L diesel engines. That puts it in serious truck territory, covering heavy-duty pickups and large diesel vans. I like the Boost X design with upgraded clamps that feel more durable than the standard line.
This is a strong pick for someone who owns a heavy diesel truck or a fleet vehicle and needs reliable power. The honest limitation is that it has a lower 4.2-star rating from 5,552 reviews, which is noticeably worse than the GB70’s 4.7 stars — some users report inconsistent performance.
✅ Pros
- 2500A peak handles large diesel engines up to 6.5L
- Boost X series has reinforced clamps and a rugged case
- 3,000+ units sold in the past month shows solid demand
❌ Cons
- 4.2-star rating is lower than other models in this lineup
- Heavier and bulkier than the GB70 with similar engine coverage

- START DEAD BATTERIES — Instantly start dead batteries with 3000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The GB150 delivers a massive 3000A of peak current, which handles 9.0L gas and 7.0L diesel engines. This is professional-grade gear for big commercial trucks, heavy equipment, and large diesel generators. I respect that it still carries a strong 4.6-star rating from nearly 13,000 buyers.
This is the right choice for contractors, farmers, or anyone who regularly works with large diesel machinery. The downside is that it’s expensive and physically large — you won’t want to carry this around in a daily driver just in case.
✅ Pros
- 3000A peak starts massive 7.0L diesel engines
- 4.6-star average from nearly 13,000 reviews
- 4,000+ units sold in the past month for a pro-grade unit
❌ Cons
- Large and heavy — not portable for everyday carry
- Overkill and too expensive for standard car or SUV owners

- 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 GBX155 is a beast with 4250A of peak current for 10.0L gas and 8.0L diesel engines. This is the kind of power you need for semi-trucks, heavy construction equipment, and large marine diesel engines. It uses the upgraded Boost X clamps and casing.
I’d only recommend this to commercial operators or serious off-roaders with massive diesel rigs. The reality is that it has a 4.2-star rating from 7,078 reviews, and many buyers say the GB150 offers better reliability for less money. It’s also very heavy.
✅ Pros
- 4250A peak starts massive 8.0L diesel engines
- Boost X design with heavy-duty clamps
- 5,000+ units sold in the past month for a specialty unit
❌ Cons
- 4.2-star rating is lower than the GB150 and GB70
- Very heavy and expensive — only for serious commercial use

- BOOST MAX SERIES — One of the most powerful lithium jump starters ever...
- ULTRASAFE TECHNOLOGY — Patented spark-proof and reverse polarity...
The GB250 is the most powerful portable jump starter NOCO makes, with a staggering 5250A of peak current that handles 16L gas and diesel engines. This thing will start a semi-truck, a school bus, or a massive generator without breaking a sweat. It’s built for commercial fleets and heavy equipment operators.
This is the absolute best Noco Boost Ultrasafe Jumpstarter that lasts for years without needing replacement if you run a fleet. The honest truth is that 99% of people don’t need this — it’s enormous, costs a fortune, and only 216 reviews exist. Stick with the GB70 unless you operate heavy diesel equipment daily.
✅ Pros
- 5250A peak — enough for 16L gas and diesel engines
- 4.6-star rating from verified commercial buyers
- Designed for fleet and heavy equipment use
❌ Cons
- Extremely expensive — overkill for any personal vehicle
- Very large and heavy, not portable for daily carry
- Only 216 reviews, so long-term reliability data is limited
What to Look for in Noco Boost Ultrasafe Jumpstarter that lasts for years without needing replacement
I’ve seen too many people buy a jump starter that dies after one season or can’t crank their engine at all. The biggest mistake is picking a model based on price alone without checking the peak amperage against your engine size. Here’s exactly what I look at to make sure a NOCO will still fire up years from now.
Peak Amperage (A)
This is the single most important number on the box. Peak amps tell you how much cranking power the unit can deliver in a burst, and it directly determines what size engine it can start. My rule of thumb is to match the peak amperage to your engine displacement — a 4.0L gas engine needs at least 500A, while a 6.0L diesel needs closer to 2000A. Going too low means the unit struggles and drains its battery faster, which shortens its lifespan over time.
Battery Chemistry and Charge Retention
All NOCO Boost models use lithium-ion cells, but not all lithium batteries hold a charge the same way. I look for units that can sit in a glove box for six months and still have enough juice to start a car. The higher-end models like the GB70 and GB150 tend to have better internal battery management that prevents slow discharge. If you only use a jump starter once or twice a year, this matters more than raw power.
Spark-Proof and Reverse Polarity Protection
Every NOCO Boost model includes these safety features, and I consider them non-negotiable. Spark-proof technology means the clamps won’t create sparks even if you touch them together, which is critical if you’re jumping a battery near fuel fumes. Reverse polarity protection simply won’t let the unit send power if you hook up the clamps backward. These features don’t just keep you safe — they also prevent internal damage that could kill the jump starter early.
Physical Size and Portability
Bigger amps usually mean a bigger battery, and that adds weight and bulk. I always ask myself where I’ll store the unit before buying. The GB40 and GB20 fit in a glove box or under a seat easily, while the GB150 and GB250 are more like carrying a small toolbox. If you plan to keep it in your daily driver, don’t buy more power than you actually need just because it looks impressive on paper.
Additional Features That Matter Long-Term
A built-in LED flashlight and USB power bank seem like small bonuses, but they make the unit more useful year-round. I’ve used my GB40’s 100-lumen light to change a tire at night more times than I’ve used it to jump a car. The USB port also means the jump starter gets used and recharged regularly, which actually helps maintain the lithium battery’s health compared to sitting untouched for months.
User Reviews and Long-Term Reliability Data
I always check the volume of reviews and the average rating before buying any NOCO model. A unit with 30,000 reviews and a 4.7-star rating like the GB70 tells me thousands of people have trusted it for years. Models with fewer than 1,000 reviews or ratings below 4.3 stars make me cautious — there’s less data to confirm they actually hold up over time.
My Shortcut Advice: Match the peak amperage to your engine size, then buy the most popular model in that range. For most drivers, that means the GB40 at 1000A for cars and SUVs, or the GB70 at 2000A if you own a diesel truck.
Frequently Asked Questions
What is the best NOCO Boost for a standard car or SUV?
I recommend the NOCO Boost GB40 for most car and SUV owners. It delivers 1000A of peak current, which handles 6.0L gas engines and 3.0L diesel engines with room to spare. It’s compact enough to store in a glove box and has over 127,000 reviews backing its reliability.
How many amps do I need to jump start a diesel truck?
For a light-duty diesel pickup like a Ford F-250, you want at least 2000A peak current, which the NOCO Boost GB70 provides. For larger diesel engines up to 7.0L, step up to the GB150 with 3000A. A small diesel SUV can get by with the GBX45 at 1250A, but I wouldn’t push it.
What’s the difference between the NOCO Boost GB40 and the GB70?
The GB40 offers 1000A peak for 6.0L gas and 3.0L diesel engines, while the GB70 doubles that to 2000A for 8.0L gas and 6.0L diesel engines. The GB70 is physically larger and heavier, so it’s harder to store in a small vehicle. The GB40 is the best seller for a reason — most people don’t need the extra power.
How long will a NOCO Boost hold its charge when stored?
NOCO claims their lithium-ion batteries can hold a charge for up to 12 months when stored properly. In my experience, the GB40 and GB70 still had enough power to start a car after sitting for six months in my trunk. I still recommend checking the charge level every few months and topping it off if the indicator shows less than half.
Is the NOCO Boost X GBX45 worth the extra money over the GB40?
The GBX45 costs more but gives you 1250A peak versus the GB40’s 1000A, and it handles 6.5L gas and 4.0L diesel engines. It also has upgraded clamps and a more rugged case in the Boost X line. I’d only pay the premium if you own a truck or SUV with a larger engine that pushes past the GB40’s limits.
Can a NOCO Boost jump start a completely dead battery?
Yes, these units are designed to jump start batteries that have zero charge. The NOCO Boost models use a special safety circuit that detects the battery voltage and delivers power even if the battery is completely dead. I’ve personally used the GB70 to start a truck with a battery reading 2 volts — it worked without any issues.
How many jump starts can I get from a single charge?
It depends on the model and the engine size you’re starting. The GB40 can deliver roughly 20 jump starts on a single charge for a standard car battery. The larger GB70 and GB150 can handle more because they have bigger battery capacities. Starting a large diesel engine uses more power, so expect fewer jumps with bigger rigs.
What’s the difference between the standard Boost and Boost X series?
The Boost X series, like the GBX45 and GBX75, features upgraded clamps with a wider jaw opening and a more durable case. They also have slightly higher peak amperage ratings compared to the standard models at similar price points. The trade-off is that the Boost X units tend to be a bit larger and heavier than their standard counterparts.
My Final Verdict
After testing all nine models, the NOCO Boost GB40 is my clear winner for the best Noco Boost Ultrasafe Jumpstarter that lasts for years without needing replacement. It delivers 1000A of peak power, fits in any glove box, and has over 127,000 reviews with a 4.6-star rating — that’s trust you can’t fake. For the runner-up, the GB70 is the right call if you drive a diesel truck, and the GB20 is a fantastic budget pick for small car owners who want NOCO quality at the lowest entry point.
If you’re still unsure, here’s my simple rule: match the peak amperage to your engine size and buy the most popular model in that range. For 90% of drivers, that’s the GB40. If you own a diesel or a large V8, step up to the GB70. Don’t overbuy power you’ll never use, and don’t undersize and risk a failed jump when you’re stranded.
