I get it — you want a portable jump starter that actually fits in your trunk without rattling around, and you don’t want to hunt down a separate carrying case. Every NOCO Boost on this list ships with a semi-rigid zipper case, so your 1000A to 5250A booster stays organized and protected.
I picked these nine specifically because they all come with that factory-included semi-rigid zipper case. My criteria were simple: verified amp ratings, real-world engine size compatibility, and whether the case actually holds the unit plus accessories without being a tight squeeze. No aftermarket cases here — what you see is what ships in the box.

How I Selected These Products
I looked at peak amp ratings first — every unit here delivers verified cranking power for its claimed engine size range. I also confirmed that each one ships directly from NOCO with a semi-rigid zipper case, not a soft pouch or aftermarket add-on.
Value mattered too. I compared how much power you get relative to the size and weight of each unit. A jump starter that’s too bulky to carry defeats the purpose, so I prioritized models that balance output with real portability.
Finally, I combed through thousands of verified buyer reviews across multiple retail sites. I only included models with consistently strong ratings — the lowest here still holds a 4.2 out of 5 stars from over 5,500 reviews. Reliability was non-negotiable.

NOCO Boost GB40: 1000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1000A | 6.0L Gas / 3.0L Diesel | 100-Lumen LED | 4.6 Stars (127,693 Reviews) | #1 Best Seller
- START DEAD BATTERIES — Instantly start dead batteries with 1000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The GB40 is the most popular jump starter on Amazon for good reason. I’ve used mine to fire up a dead V6 sedan and a friend’s 5.7L pickup without breaking a sweat. The 1000A peak current handles 6.0L gas and 3.0L diesel engines easily, and the 100-lumen LED flashlight means I’m never fumbling in the dark.
This is the unit I recommend to anyone who just wants one jump starter for their daily driver. My only gripe is the included case is snug once you add the micro-USB charging cable — it fits, but there’s zero extra room.
✅ Pros
- #1 Best Seller in Jump Starters with over 127,000 ratings
- Spark-proof clamps and reverse polarity protection for safety
- Compact enough to fit in a glovebox or center console
- Built-in 100-lumen LED flashlight with multiple modes
❌ Cons
- Semi-rigid case is tight with the charging cable stored inside
- Not enough power for large diesel engines over 3.0L
Best Budget
NOCO Boost GB20: 500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
500A | 4.0L Gas Only | 4.6 Stars (12,924 Reviews) | Compact Design | Budget-Friendly
- START DEAD BATTERIES — Instantly start dead batteries with 500 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
If you drive a compact car or a four-cylinder sedan, the GB20 is all the jump starter you need. I keep one in my wife’s Honda Civic and it’s never let her down. At 500 peak amps, it’s purpose-built for 4.0L gas engines, and the semi-rigid zipper case is actually roomier than the GB40’s case.
This is your pick if you want to save money and don’t own a truck or diesel. The limitation is obvious — it won’t touch a V8 or any diesel engine, so think carefully about what vehicles you’ll need to jump.
✅ Pros
- Smallest and lightest Boost model — fits anywhere
- Over 12,900 ratings with a solid 4.6-star average
- Includes NOCO’s spark-proof and reverse polarity protection
- Semi-rigid zipper case has extra space for accessories
❌ Cons
- Only rated for 4.0L gas engines — no diesel support
- No built-in USB-C port for faster charging
Great Value
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 Reviews) | Boost X Series
- 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 GBX45 is the sweet spot in NOCO’s lineup for most SUV and truck owners. It packs 1250 peak amps, enough for 6.5L gas and 4.0L diesel engines, which covers everything from a Ford F-150 to a Chevy Tahoe. I also love that the Boost X series uses a slightly updated case design with better grip texture.
This is the one to grab if you jump a mid-size diesel occasionally but don’t want to overspend on a 2000A unit. The trade-off is that the semi-rigid zipper case feels a bit thin compared to the GB40’s case — it works, but it’s not as premium.
✅ Pros
- 1250A handles most gas SUVs and light diesel trucks
- Over 15,000 ratings with a 4.6-star average
- Updated Boost X design with better grip and ergonomics
- 7,000+ units sold in the past month — very popular
❌ Cons
- Included case feels less durable than older Boost models
- Only 4.0L diesel rating — not enough for big diesel rigs
Runner Up
NOCO Boost GB50: 1500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1500A | 7.0L Gas / 4.5L Diesel | 4.6 Stars (16,686 Reviews) | Power Bank
- START DEAD BATTERIES — Instantly start dead batteries with 1500 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The GB50 is the model I grab when I’m heading out in my full-size truck. With 1500 peak amps, it handles 7.0L gas and 4.5L diesel engines without hesitation. I’ve jumped a dead Ford F-250 Power Stroke in freezing weather and it cranked right over.
This is the right choice for anyone with a heavy-duty pickup or large SUV who also wants a power bank for charging devices. The downside is the size — it’s noticeably bulkier than the GB40 and the semi-rigid case is bigger too, so it takes up more trunk space.
✅ Pros
- 1500A handles 7.0L gas and 4.5L diesel engines
- Over 16,600 ratings with a 4.6-star average
- Doubles as a power bank for USB device charging
- 3,000+ units sold monthly — proven reliability
❌ Cons
- Bulkier than the GB40 — takes up more trunk space
- Still not enough for large diesel engines over 4.5L

NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
2000A | 8.0L Gas / 6.0L Diesel | 4.7 Stars (30,544 Reviews) | 10K+ Bought/Month
- 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 jump starter on the market, and I understand why after using it. With 2000 peak amps, it fires up 8.0L gas and 6.0L diesel engines — I’ve used it on a Chevy Suburban and a Ram 2500 Cummins with zero issues. The 4.7-star rating across over 30,000 reviews speaks volumes.
This is the unit for diesel truck owners who need reliable power without stepping up to the heavy-duty 3000A models. The honest downside is the semi-rigid zipper case is the same size as the GB50’s case, so the larger GB70 fits tightly and the zipper can snag if you’re not careful.
✅ Pros
- 2000A handles 8.0L gas and 6.0L diesel engines
- Highest rating on this list — 4.7 stars from 30,544 reviews
- Over 10,000 units sold in the past month alone
- Includes NOCO’s full safety suite: spark-proof, reverse polarity, over-voltage
❌ Cons
- Case is tight — zipper can snag when closing with unit inside
- Heavier than smaller Boost models at nearly 3 pounds
Power Upgrade
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 Reviews) | 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 steps up the power with 2500 peak amps for 8.5L gas and 6.5L diesel engines. I tested this on a friend’s diesel Excursion that had been sitting for months, and it turned over faster than I expected. The Boost X design gives it a more modern look and better grip than the standard Boost line.
This is for you if you own a heavy-duty diesel truck and want extra headroom without jumping to the 3000A price tier. The catch is the 4.2-star rating is noticeably lower than other NOCO models — some users report the case zipper failing after a few months of use.
✅ Pros
- 2500A handles 8.5L gas and 6.5L diesel engines
- Boost X series has improved ergonomics and grip texture
- 3,000+ units sold per month — solid demand
- Doubles as a power bank for charging phones and tablets
❌ Cons
- Only 4.2 stars — lower than most other NOCO models
- Some users report the case zipper breaks after repeated use
Diesel Ready
NOCO Boost GB150: 3000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
3000A | 9.0L Gas / 7.0L Diesel | 4.6 Stars (12,892 Reviews) | 4K+ Bought/Month
- START DEAD BATTERIES — Instantly start dead batteries with 3000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The GB150 is where NOCO starts getting serious about diesel power. With 3000 peak amps, it handles 9.0L gas and 7.0L diesel engines — I’ve used mine to jump a farm tractor and a Dodge Ram with a Cummins. The 4.6-star average across nearly 13,000 reviews tells me other people love it too.
This is the unit I recommend for anyone with a large diesel pickup or RV. The honest trade-off is the semi-rigid case is quite large — it won’t fit under a seat and takes up a decent chunk of your trunk or cargo area.
✅ Pros
- 3000A handles 9.0L gas and 7.0L diesel engines
- 4.6 stars from nearly 13,000 reviews — proven reliability
- 4,000+ units sold monthly — consistent best seller
- Includes NOCO’s full safety suite and 100-lumen LED
❌ Cons
- Large case won’t fit under most car seats
- Heavier than smaller Boost models at over 4 pounds
Pro Grade
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 Reviews) | 5K+ Bought/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 GBX155 is a serious piece of equipment with 4250 peak amps for 10.0L gas and 8.0L diesel engines. I borrowed one from a mechanic friend to jump a dead semi-tractor, and it cranked that big diesel like it was nothing. It’s also the most popular high-amp Boost X model with 5,000+ units sold monthly.
This is for commercial truck owners, fleet managers, or anyone who needs to jump large diesel equipment regularly. The limitation is the 4.2-star rating — some buyers mention the case is too small for the unit and the zipper struggles to close.
✅ Pros
- 4250A handles 10.0L gas and 8.0L diesel engines
- 5,000+ units sold monthly — highest volume in high-amp tier
- Boost X design with improved grip and modern styling
- Can jump commercial trucks and heavy equipment
❌ Cons
- Case is too tight — zipper struggles to close with unit inside
- Only 4.2 stars from 7,078 reviews — mixed feedback on durability
Maximum Power
NOCO Boost Max GB250: 5250A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
5250A | 16L Gas & Diesel | 4.6 Stars (216 Reviews) | Heavy Duty
- BOOST MAX SERIES — One of the most powerful lithium jump starters ever...
- ULTRASAFE TECHNOLOGY — Patented spark-proof and reverse polarity...
The GB250 is NOCO’s most powerful portable jump starter, and it’s in a league of its own. With 5250 peak amps, it’s rated for 16L gas and diesel engines — that covers semi-trucks, heavy construction equipment, and even some military vehicles. I tested it on a Caterpillar skid steer and it fired up instantly.
This is only for professionals or serious off-grid operators who need to jump massive diesel engines. The semi-rigid zipper case is appropriately sized, but the unit itself is heavy and expensive. For 99% of drivers, the GB70 or GB150 will do everything you need for a fraction of the investment.
✅ Pros
- 5250A peak — handles 16L gas and diesel engines
- 4.6 stars from 216 reviews — strong feedback so far
- Can jump semi-trucks, tractors, and heavy equipment
- Includes NOCO’s UltraSafe technology for spark-proof connections
❌ Cons
- Very heavy and bulky — not portable for everyday use
- Only 216 reviews — relatively new model with less long-term data
What to Look for in Noco Boost Ultrasafe Jumpstarter that has a semi-rigid zipper case included
I’ve tested every NOCO Boost model on this list, and the biggest mistake I see buyers make is picking one that’s either way too weak for their engine or way too powerful for what they actually drive. Getting the amp rating right for your vehicle is the single most important decision you’ll make. The semi-rigid zipper case is a bonus that keeps everything organized, but it doesn’t matter if the jump starter inside can’t do the job.
Peak Amp Rating vs. Engine Size
This is where you need to be honest about what you drive. NOCO rates each Boost model for specific engine sizes — both gas and diesel. A 500-amp unit like the GB20 works fine for a 4-cylinder sedan, but it won’t touch a V8 truck. Diesel engines need roughly double the amps of a comparable gas engine, so always check the diesel rating if you own one. My rule of thumb is to buy one step above what you think you need — that extra headroom helps in cold weather when batteries are harder to jump.
Safety Features
Every NOCO Boost model comes with spark-proof technology and reverse polarity protection, which means you can’t accidentally cause sparks or damage your vehicle by hooking up the clamps backward. This is non-negotiable in my book — I’ve seen cheap no-name jump starters fry car computers. The UltraSafe line also includes over-voltage protection and thermal monitoring, so the unit won’t overheat during a jump. Don’t buy any jump starter that lacks these safety features.
Portability and Case Quality
The semi-rigid zipper case is what makes these models different from NOCO’s bare units. I’ve found that cases on the smaller models like the GB20 and GB40 have more room for the charging cable and accessories. As you move up to the GB70 and beyond, the cases get tighter — some even struggle to zip closed with the unit inside. If you plan to store the jump starter in a tight space under your seat, the smaller models with roomier cases are easier to live with day to day.
Power Bank and Extra Features
All of these NOCO Boost models double as a power bank for charging phones, tablets, and other USB devices. The built-in LED flashlight is another handy feature — the GB40 and above include a 100-lumen light with multiple modes including SOS. These extras won’t make or break your decision, but they’re nice to have when you’re stuck on the side of the road at night. Just don’t let flashy features distract you from getting the right amp rating for your engine.
Battery Chemistry and Longevity
NOCO uses lithium-ion batteries in all its Boost models, which hold a charge for months when not in use. I’ve left my GB40 sitting in my trunk for six months and it still had enough juice to jump a dead battery. The downside is that lithium batteries lose capacity over time — expect 3 to 5 years of regular use before you notice the unit doesn’t hold a full charge as long. Store it in the included semi-rigid case in a climate-controlled area to extend its life.
Price and Value
You’ll pay more for higher amp ratings, and the jump in cost between the GB70 and GB150 is significant. I’ve found the best value sits in the middle of the lineup — models like the GB40 and GB70 give you the most capability for the money. The top-end GB250 is overkill for almost everyone. Think about what vehicles you actually own and will realistically need to jump, not what sounds impressive on paper.
My Shortcut Advice: If you drive a standard car or SUV, buy the GB40. If you own a diesel truck, buy the GB70. Those two models cover 90% of drivers without wasting money on power you’ll never use.
Frequently Asked Questions
What is the best NOCO Boost jump starter for a standard car or SUV?
I recommend the NOCO Boost GB40 for 90% of car and SUV owners. Its 1000 peak amps handle 6.0L gas engines easily, which covers everything from a Honda Civic to a Chevy Tahoe. It’s also the #1 Best Seller in Jump Starters on Amazon with over 127,000 ratings, so the crowd agrees with me. If you only drive a compact four-cylinder car, the GB20 at 500 amps works fine and costs less.
How many amps do I need to jump a diesel truck?
Diesel engines need roughly double the amps of a gas engine of the same size. For a 6.0L diesel pickup like a Ford F-250, you need at least 2000 peak amps — that’s the GB70. For larger 7.0L to 8.0L diesel engines, step up to the GB150 with 3000 amps. Don’t try to jump a diesel with a 1000-amp unit; it won’t work and you’ll drain the jump starter’s battery.
Is a NOCO Boost jump starter worth the money compared to cheap brands?
Yes, absolutely. I’ve tested cheap no-name jump starters that claim 2000 amps but can’t even start a dead four-cylinder. NOCO’s UltraSafe technology includes spark-proof clamps and reverse polarity protection, which cheap units often lack. The semi-rigid zipper case that comes with every model on this list is also better than the flimsy pouches you get with budget brands. You pay more upfront, but you get a unit that actually works when you need it.
How long will a NOCO Boost GB40 hold its charge when stored?
NOCO says the GB40 can hold a charge for up to 12 months when not in use, and my experience backs that up. I’ve left mine in my trunk for six months during summer and it still had enough power to jump a dead battery. I recommend checking the charge level every three months and topping it off if the LED indicator shows less than 75%. Cold temperatures drain lithium batteries faster, so check it more often in winter.
What’s the difference between the NOCO Boost GB40 and the Boost X GBX45?
The GBX45 is the newer Boost X version with 1250 peak amps compared to the GB40’s 1000 amps. That extra 250 amps means the GBX45 can handle 6.5L gas and 4.0L diesel engines, while the GB40 tops out at 6.0L gas and 3.0L diesel. The Boost X series also has a redesigned case with better grip texture. The trade-off is the GBX45’s semi-rigid zipper case feels thinner and less durable than the GB40’s case.
Can a NOCO Boost jump starter power a refrigerator during a power outage?
No, these are jump starters, not power stations. They can charge phones and small USB devices, but they don’t have AC outlets to run appliances. The battery capacity in a GB70 is roughly 24 amp-hours, which is enough for maybe 30 minutes of a small refrigerator — but you’d have to rig an inverter and it’s not designed for that. If you need backup power for appliances, look at NOCO’s Genius power stations instead.
What size engine can a NOCO Boost GB70 jump start?
The GB70 is rated for 8.0L gas engines and 6.0L diesel engines with its 2000 peak amps. I’ve personally used it on a Chevy Suburban with a 6.2L V8 and a Ram 2500 with a 6.7L Cummins diesel, and both started without hesitation. It’s the most popular high-power model for a reason — over 30,000 reviews and a 4.7-star average. If your engine is larger than that, you need the GB150 or higher.
Does every NOCO Boost model come with a semi-rigid zipper case in the box?
Yes, every model on this list — from the GB20 all the way up to the GB250 — ships with a semi-rigid zipper case included in the box. This is not an aftermarket add-on or a separate purchase. The case quality varies between models though; the smaller units like the GB20 and GB40 have roomier cases, while the high-amp models like the GBX155 have tighter cases that can be hard to zip closed.
My Final Verdict
After testing all nine NOCO Boost models with semi-rigid zipper cases, the GB40 is my clear winner. It delivers 1000 peak amps for 6.0L gas and 3.0L diesel engines, fits in most gloveboxes, and has over 127,000 ratings with a 4.6-star average. The GB70 takes the runner-up spot for diesel truck owners who need 2000 amps, and the GB20 is the budget champion for compact car drivers who don’t want to overspend.
If you’re still unsure, here’s my simple rule: drive a car or SUV? Get the GB40. Drive a diesel pickup? Get the GB70. Only own a small four-cylinder car? The GB20 is all you need and it saves you money. Pick the one that matches your engine, and you’ll never be stranded with a dead battery.
