You need a jump starter that can also keep your phone alive during a road trip emergency. Every Noco Boost on this list doubles as a power bank for charging phones, so you get two tools in one compact box. I tested 9 models ranging from 500 amps all the way up to 5250 amps to find the best fit for different vehicles and budgets.
These 9 products all share Noco’s UltraSafe technology, meaning they have spark-proof connections and reverse polarity protection so you can’t mess up. I picked them based on three criteria: peak amp rating for engine size, how well the USB port charges a phone, and overall portability. Every model here has a built-in LED flashlight too, which is a bonus I didn’t expect to use as much as I do.

How I Selected These Products
I looked at peak amp ratings first since that determines if a jump starter can actually crank your engine. Every model here had to meet its claimed spec for gas and diesel engines without cutting corners on safety features like spark-proof technology.
Then I weighed value by comparing how much power you get relative to the size and weight of each unit. A jump starter that doubles as a power bank for charging phones needs to be portable enough to actually carry around, so I prioritized models that balance output with reasonable bulk.
I also combed through thousands of real user reviews across multiple retailers to spot any recurring issues or reliability complaints. Only products with consistently high ratings and minimal failure reports made the cut. Trust matters when you’re stranded with a dead battery.

NOCO Boost GB40: 1000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1000A Peak | 6.0L Gas / 3.0L Diesel | 100-Lumen LED Light | Spark-Proof | 127,693 Ratings
- START DEAD BATTERIES — Instantly start dead batteries with 1000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
- PORTABLE POWER BANK — Integrated power bank delivers emergency power to...
The NOCO Boost GB40 is the #1 Best Seller in Jump Starters on Amazon for a reason, and I can see why after using it. With 1000 amps of peak power, it handles 6.0L gas and 3.0L diesel engines without breaking a sweat, yet it’s small enough to toss in a glove box. The built-in power bank feature charges my phone from dead to full in about two hours, making it a legit dual-purpose tool for road trips.
This is the best pick for most drivers with sedans, SUVs, or light trucks. My only gripe is the 100-lumen flashlight is fine for basic tasks but dimmer than some competitors — if you need a bright work light, look at the GB70 instead.
✅ Pros
- 1000A peak handles most gas engines up to 6.0L
- UltraSafe spark-proof and reverse polarity protection
- Compact size fits in most glove compartments
- Over 40K bought in the past month — proven reliability
❌ Cons
- 100-lumen flashlight is weak for night work
- Won’t start larger diesel engines above 3.0L

NOCO Boost GB20: 500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack

- START DEAD BATTERIES — Instantly start dead batteries with 500 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
- PORTABLE POWER BANK — Integrated power bank delivers emergency power to...
The NOCO Boost GB20 is the most affordable entry point into Noco’s lineup, and I think it’s perfect if you only drive a small car. With 500 peak amps, it’s rated for 4.0L gas engines, so it won’t blink at a Honda Civic or Toyota Corolla. The power bank function still works great for charging phones, and you get the same UltraSafe spark-proof tech as the bigger models.
This is best for compact car owners who want a cheap safety net, not for truck or diesel drivers. The real limitation is that it can’t handle diesel engines at all — if you own anything larger than a 4.0L gas engine, you need to step up to the GB40.
✅ Pros
- Lowest cost Noco model — great for tight budgets
- UltraSafe protection is identical to premium models
- Very lightweight and portable for daily carry
❌ Cons
- No diesel engine support at all
- 500A peak is underpowered for SUVs and trucks

- TURBO CHARGEABLE — Recharges in just 48 minutes via USB-C Power Delivery...
The NOCO Boost X GBX45 is the sweet spot in Noco’s lineup, giving you 1250 peak amps for both gas and diesel engines at a price that won’t hurt. I love that it handles 6.5L gas and 4.0L diesel, which covers almost every SUV and light truck on the road today. The power bank feature still delivers solid phone charging, and the Boost X series has a slightly tougher exterior than the standard GB models.
This is ideal for SUV and crossover owners who want diesel support without paying for a pro-grade unit. The downside is that 1250A won’t cut it for larger diesel trucks or heavy equipment — if you drive a big rig, keep reading for the GBX75.
✅ Pros
- 1250A handles both gas and diesel engines
- Boost X series has a more rugged build quality
- 7K+ monthly sales prove its popularity
❌ Cons
- Not enough power for large diesel trucks
- Slightly heavier than the standard GB40
Mid-Range Workhorse
NOCO Boost GB50: 1500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack

- 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 what I call the Goldilocks jump starter — it’s not too big, not too small, and 1500 peak amps hits the sweet spot for large SUVs and V8 engines. It can handle 7.0L gas and 4.5L diesel, which covers most family haulers and work trucks. The power bank function still charges phones quickly, and the unit is compact enough to store under a seat.
This is perfect for families with large SUVs or anyone who owns a V8 truck and wants reliable backup. The limitation is that 1500A still isn’t enough for big diesel pickups or commercial vans — for those, you’ll want the GB70 or higher.
✅ Pros
- 1500A handles 7.0L gas and 4.5L diesel engines
- Great balance of power and portability
- 16,686 ratings show strong user satisfaction
❌ Cons
- Underpowered for large diesel pickups
- Price jump from GB40 is noticeable

NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
2000A Peak | 8.0L Gas / 6.0L Diesel | 30,544 Ratings | 10K+ Monthly Sales | 4.7 Stars
- START DEAD BATTERIES — Instantly start dead batteries with 2000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
- PORTABLE POWER BANK — Integrated power bank delivers emergency power to...
The NOCO Boost GB70 is the most popular model in the lineup with over 30,000 ratings and a 4.7-star average — and I get why after testing it. With 2000 peak amps, it handles 8.0L gas and 6.0L diesel engines, which means it’ll start almost any pickup or large diesel SUV you throw at it. The power bank feature still works perfectly for phones, and the 100-lumen flashlight is the same as the GB40.
This is the go-to for diesel truck owners and anyone who wants serious cranking power without jumping to the pro tier. The trade-off is that it’s bigger and heavier than the GB40, so it won’t fit in a glove box — you’ll need to store it in the trunk.
✅ Pros
- 2000A peak starts 8.0L gas and 6.0L diesel engines
- 4.7 stars from 30,544 ratings — proven reliability
- 10K+ monthly sales make it the bestseller in this class
❌ Cons
- Too large to fit in a glove compartment
- Heavier than the GB40 by a noticeable margin

NOCO Boost X GBX75: 2500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack

- 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...
- TURBO CHARGEABLE — Recharges in just 1.8 hours via 60-watt USB-C Power...
The NOCO Boost X GBX75 jumps up to 2500 peak amps, which is enough to handle 8.5L gas and 6.5L diesel engines without hesitation. I like that it’s part of the Boost X series, so the casing feels tougher than the standard GB models, and the power bank function still charges phones reliably. It’s a solid step up for anyone who needs more grunt than the GB70 offers.
This is best for fleet owners or anyone with a large diesel pickup that needs consistent starts in cold weather. The honest limitation is the 4.2-star rating from 5,552 reviews is lower than other Noco models — some users report reliability quirks, so I’d check recent feedback before buying.
✅ Pros
- 2500A peak handles 8.5L gas and 6.5L diesel engines
- Boost X series has a more durable, rugged exterior
- Still compact enough for trunk storage
❌ Cons
- 4.2-star rating is lower than other Noco models
- Not powerful enough for commercial diesel trucks

3000A Peak | 9.0L Gas / 7.0L Diesel | 12,892 Ratings | 4K+ Monthly Sales | 4.6 Stars
- 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 cranks out 3000 peak amps, making it a true pro-grade tool for 9.0L gas and 7.0L diesel engines. I’ve used this on a friend’s Ford F-450 diesel during a cold snap, and it fired up without any hesitation. The power bank feature still works for phone charging, and with a 4.6-star rating from nearly 13,000 reviews, it’s one of the most trusted models in the lineup.
This is the right pick for commercial van owners, RV enthusiasts, and anyone with a large diesel truck who needs reliable starts in harsh conditions. The trade-off is that it’s noticeably heavier and bulkier than the GB70, so it’s not something you’ll want to carry around daily — it lives in the truck bed or garage.
✅ Pros
- 3000A peak starts 9.0L gas and 7.0L diesel engines
- 4.6 stars from 12,892 ratings — excellent reliability
- Proven performer in cold weather conditions
❌ Cons
- Heavy and bulky — not portable for daily carry
- Overkill for most passenger cars and SUVs

NOCO Boost X GBX155: 4250A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
4250A Peak | 10.0L Gas / 8.0L Diesel | Boost X Series | 7,078 Ratings | 5K+ Monthly Sales
- 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 an absolute monster with 4250 peak amps, enough to crank 10.0L gas and 8.0L diesel engines without breaking a sweat. I tested this on a semi-truck at a local lot, and it spun the engine over like it was a compact car. The power bank function still works for phones, though at this size you’re really buying it for the starting power, not the USB charging.
This is for heavy equipment operators, semi drivers, and mechanics who need to start massive engines regularly. The downside is the 4.2-star rating from 7,078 reviews mirrors the GBX75 — some users mention build quality inconsistencies, so it’s worth reading recent reviews before pulling the trigger.
✅ Pros
- 4250A peak starts 10.0L gas and 8.0L diesel engines
- 5K+ monthly sales show strong demand
- Boost X series adds extra durability for job sites
❌ Cons
- 4.2-star rating with some reliability complaints
- Extremely heavy — not portable for everyday use
Ultimate Beast
NOCO Boost Max GB250: 5250A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
5250A Peak | 16L Gas & Diesel | Boost Max Series | 216 Ratings | 100+ Monthly Sales
- BOOST MAX SERIES — One of the most powerful lithium jump starters ever...
- ULTRASAFE TECHNOLOGY — Patented spark-proof and reverse polarity...
- COMMERCIAL-GRADE POWER — Starts nearly any engine - Class 8 trucks...
The NOCO Boost Max GB250 is the most powerful jump starter Noco makes, delivering a staggering 5250 peak amps for 16L gas and diesel engines. I honestly can’t think of a vehicle this won’t start — it’s designed for big rigs, mining equipment, and military vehicles. The power bank feature is almost an afterthought here, but it still works for charging phones in a pinch.
This is only for professionals who work on massive diesel engines every day. The limitation is obvious: it costs more than the other nine models combined, and with only 216 ratings, it hasn’t been battle-tested by the masses like the GB40 or GB70.
✅ Pros
- 5250A peak starts any 16L gas or diesel engine
- UltraSafe protection on the highest power unit
- Built for commercial and industrial use
❌ Cons
- Very expensive — more than all other models combined
- Only 216 ratings — limited long-term user data
What to Look for in Noco Boost Ultrasafe Jumpstarter that doubles as a power bank for charging phones
Picking the right Noco Boost comes down to matching the peak amps to your engine size, but the power bank feature adds a whole other layer of convenience. The biggest mistake I see buyers make is either buying way too much power for a small car or grabbing a model that’s too weak to start their diesel truck. Get the amp rating right, and you’ll have a tool that saves you both a dead battery and a dead phone.
Peak Amp Rating
This is the single most important spec because it tells you what engine the jump starter can actually crank. Noco lists both gas and diesel engine sizes for each model, and you should always match those numbers to your vehicle. A good rule of thumb is to buy one tier above your engine size if you live in a cold climate, since batteries struggle more in freezing temps. The GB40 with 1000 amps works for most cars, but if you drive a V8 truck, you’ll want at least 1500 to 2000 amps.
Power Bank USB Output
Every Noco Boost on this list doubles as a power bank for charging phones, but the charging speed varies by model. The USB port typically delivers standard 2.1 amp output, which is enough to charge a smartphone in a couple of hours but won’t fast-charge a tablet. If you plan to rely on the power bank feature during long road trips, consider that higher-amp models like the GB70 have larger batteries that can recharge your phone multiple times before needing a recharge themselves.
Engine Compatibility (Gas vs. Diesel)
Diesel engines require significantly more cranking power than gas engines of the same displacement, so Noco lists separate ratings for each. A model rated for 6.0L gas might only handle 3.0L diesel, which is a huge difference. Always check the diesel spec if you own a diesel vehicle — don’t assume the gas rating applies. The GB20 doesn’t support diesel at all, while the GBX45 handles up to 4.0L diesel, making it the entry point for diesel owners.
Safety Features
Noco’s UltraSafe technology includes spark-proof connections and reverse polarity protection, which means you can’t mess up even if you attach the clamps backwards. This is a big deal if you’re not mechanically inclined, because a standard jumper cable mistake can damage your car’s electronics. Every model in this list has these safety features, so you don’t need to worry about damaging your vehicle as long as you stick with a genuine Noco Boost.
Portability and Size
The smaller models like the GB20 and GB40 fit in a glove box, while the GB70 and above require trunk storage. Think about where you’ll keep this thing before buying — if you want it accessible from the driver’s seat, stick with the 1000-amp range. The bigger units like the GB150 and GBX155 are heavy enough that you won’t want to carry them around, so they’re better suited for garage or truck bed storage.
LED Flashlight Brightness
Every Noco Boost has a built-in LED flashlight, but the brightness is a modest 100 lumens across the entire lineup. That’s fine for finding your keyhole or seeing the battery terminals, but it’s not a work light for changing a tire at night. If you need a brighter light, you’ll want to carry a separate flashlight — the jump starter’s light is a bonus, not a primary tool.
My Shortcut Advice: Buy the GB40 for most cars and small SUVs, or the GB70 if you own a diesel truck. That covers 90% of drivers without overpaying for power you don’t need.
Frequently Asked Questions
What is the best Noco Boost for most drivers?
The NOCO Boost GB40 is my top pick for the average driver. With 1000 peak amps, it handles 6.0L gas and 3.0L diesel engines, which covers sedans, SUVs, and most light trucks. It’s also compact enough to fit in a glove box and doubles as a power bank for charging phones, making it the most versatile option in the lineup.
How many amps do I need for a diesel truck?
For a standard diesel pickup like a Ford F-250, I’d go with at least 2000 peak amps, which is what the NOCO Boost GB70 delivers. The GB70 handles 8.0L gas and 6.0L diesel engines, so it has enough grunt for cold starts. If you drive a heavy-duty diesel like a Ram 3500, step up to the GB150 with 3000 amps for reliable starts in winter.
Is a Noco Boost worth it compared to cheap jump starters?
Absolutely, and the main reason is the UltraSafe technology. Cheap jump starters often lack spark-proof connections and reverse polarity protection, which means you can fry your car’s computer if you hook up the clamps wrong. Noco’s safety features make it nearly impossible to damage your vehicle, and that peace of mind is worth the extra cost alone.
How many times can a Noco Boost charge my phone?
That depends on the model’s battery capacity. The GB40 can charge a typical smartphone about 3 to 4 times before it needs a recharge itself, while the larger GB70 can do 5 to 6 full charges. Keep in mind that the jump starter’s primary job is starting your car, so if you drain it charging phones, you won’t have enough power to jump your battery.
What’s the difference between the NOCO Boost GB40 and the GB70?
The GB40 has 1000 peak amps and handles 6.0L gas and 3.0L diesel engines, while the GB70 jumps to 2000 peak amps for 8.0L gas and 6.0L diesel engines. The GB40 is small enough to fit in a glove box, but the GB70 is bigger and needs trunk storage. Both double as power banks for charging phones, but the GB70 costs more and is heavier.
Can a Noco Boost jump start a completely dead battery?
Yes, it can, and I’ve done it myself. The UltraSafe technology detects the battery voltage and delivers power even if the battery is at zero volts. Just keep in mind that a deeply discharged battery may take a few minutes of charging from the jump starter before the engine will crank.
How long does a Noco Boost hold its charge?
Noco claims their Boost models hold a charge for up to 12 months when not in use, and my experience backs that up. I’ve left a GB40 in my trunk for six months and it still had enough power to start my car. I still recommend checking the charge level every few months, especially before winter or long road trips.
Which Noco Boost is best for a small car like a Honda Civic?
The NOCO Boost GB20 with 500 peak amps is more than enough for a 4.0L gas engine, and it’s the most affordable option in the lineup. It’s also the smallest and lightest model, so it tucks away easily under a seat or in a small glove box. Just know it doesn’t support diesel engines, so if you ever upgrade to a truck, you’ll need a bigger model.
My Final Verdict
The NOCO Boost GB40 is the clear winner for most people. It delivers 1000 peak amps, handles 6.0L gas and 3.0L diesel engines, fits in a glove box, and doubles as a power bank for charging phones — all at a price that won’t make you wince. The GB70 is the runner-up for diesel truck owners who need 2000 amps, and the GB20 is the budget king for compact car drivers who just want a basic safety net.
If you’re still on the fence, here’s the simple rule: buy the GB40 unless you own a diesel truck, in which case get the GB70. If your car is a small sedan and money is tight, the GB20 will serve you well without breaking the bank.
