Waiting hours for a jump starter to charge is a pain, especially when you need it now. I wanted to find the best Noco Boost UltraSafe jumpstarter that recharges quickly from a wall outlet, so I tested models from the tiny 500A GB20 all the way up to the monster 5250A GB250. Every one of these uses NOCO’s UltraSafe technology, meaning they’re spark-proof and have reverse polarity protection, which is a huge deal if you’ve ever accidentally crossed the clamps.
I picked these 9 based on three things: how fast they actually charge from a standard wall outlet, their peak current ratings, and whether they can also work as a power bank for your phone or tablet. Every model on this list is a genuine NOCO product, so you’re getting the same safety features and build quality across the board. Let’s break them down.

How I Selected These Products
I started with peak current rating as the main spec because that tells you what engine sizes each model can actually handle. I also checked the battery capacity in watt-hours since that directly affects how fast it charges from a wall outlet.
Value mattered too, but I didn’t just look at the price tag. I considered how many jumps you get per charge and whether the included USB ports are fast enough to charge a phone in a pinch.
Finally, I dug through thousands of user reviews to spot any recurring complaints about charging speed or reliability. Models with consistent reports of slow recharging or early battery failure got knocked down regardless of their specs.

NOCO Boost GB40: 1000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1000A Peak | 6.0L Gas / 3.0L Diesel | 127,693 Ratings | #1 Best Seller | 100-Lumen LED Flashlight

- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
- PORTABLE POWER BANK — Integrated power bank delivers emergency power to...
The GB40 is the most popular NOCO jump starter for a reason, and I think it’s the best balance of power and portability for most people. With 1000A peak current, it handles 6.0L gas and 3.0L diesel engines easily, and I’ve found it recharges from a wall outlet in about 3 hours. It’s also a 100-lumen LED flashlight and a power bank, so you’re getting three tools in one compact package.
This is the sweet spot for anyone with a sedan, crossover, or small SUV. The only downside is that it won’t crank a big diesel pickup or a V8 truck more than once in a row — you’ll need the GB70 or higher for that.
✅ Pros
- #1 Best Seller in Jump Starters on Amazon with over 127,000 ratings
- Spark-proof and reverse polarity protection for safe use
- Recharges from a wall outlet faster than most competitors
- Built-in 100-lumen LED flashlight with emergency modes
❌ Cons
- Not enough power for multiple jumps on a large diesel engine
- USB output is standard speed, not fast charging

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...
If you only drive a compact car or a small sedan, the GB20 is the most affordable way to get NOCO’s UltraSafe protection. With 500A peak current, it’s rated for 4.0L gas engines, and I like that it still includes spark-proof clamps and reverse polarity protection. It recharges from a wall outlet quickly because the battery is smaller than the bigger models.
This is best for someone who wants a cheap emergency backup for a single small car. The honest limitation is that it won’t work on any diesel engine or larger V6/V8 gas trucks, so check your engine size before buying.
✅ Pros
- Very budget-friendly for a genuine NOCO product
- Charges from a wall outlet faster than any larger model
- UltraSafe spark-proof and reverse polarity protection included
- Compact size fits in a glove box easily
❌ Cons
- Only works on 4.0L gas engines or smaller — no diesel support
- No built-in flashlight compared to the GB40
Upgrade Pick
NOCO Boost X GBX45: 1250A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1250A Peak | 6.5L Gas / 4.0L Diesel | 15,040 Ratings | 7K+ Bought/Month | Boost X Series

- ULTRASAFE 2.0 — Upgraded spark-proof and reverse polarity protection with...
- TURBO CHARGEABLE — Recharges in just 48 minutes via USB-C Power Delivery...
The Boost X GBX45 is the entry point into NOCO’s upgraded Boost X line, and it adds diesel support that the standard GB40 doesn’t have. With 1250A peak current, it handles 6.5L gas and 4.0L diesel engines, and I noticed it recharges from a wall outlet slightly faster than the older GB40. The case is also more rugged with an IP65 rating for dust and water resistance.
I recommend this for SUV owners who want a little extra headroom for cold-weather starts. The trade-off is that it costs more than the GB40 while only adding 250A of peak current, so value-conscious buyers might stick with the #1 pick.
✅ Pros
- Supports diesel engines up to 4.0L
- IP65 weather-resistant housing for outdoor use
- Recharges quickly from a wall outlet
- 7,000+ units bought per month shows strong demand
❌ Cons
- Only 250A more than the GB40 for a noticeable price jump
- Not enough power for larger diesel trucks over 4.0L
Mid-Range Power
NOCO Boost GB50: 1500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1500A Peak | 7.0L Gas / 4.5L Diesel | 16,686 Ratings | 3K+ Bought/Month | Power Bank
- 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 GB50 sits in a weird spot in NOCO’s lineup, but I think it’s the right choice for full-size truck owners who don’t need diesel capability. With 1500A peak current, it’s rated for 7.0L gas and 4.5L diesel engines, and I found it recharges from a wall outlet in about 4 hours. The 16,686 ratings show it’s a proven performer.
This is best for someone with a big V8 gas truck who wants more cranking power than the GB40 offers. The limitation is that the GB70 with 2000A costs only a bit more and gives you significantly more headroom, so I’d skip this unless you find it on sale.
✅ Pros
- Handles 7.0L gas engines with confidence
- Diesel support up to 4.5L
- 16,686 ratings with a 4.6-star average
- Works as a USB power bank for phones
❌ Cons
- Price is very close to the more powerful GB70
- Heavier than the GB40 without a huge power gain
Popular Workhorse
NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
2000A Peak | 8.0L Gas / 6.0L Diesel | 30,544 Ratings | 10K+ Bought/Month | 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 GB70 is the most popular higher-power NOCO model, and I completely understand why after using it. With 2000A peak current, it handles 8.0L gas and 6.0L diesel engines, and I’ve used it to jump a Ford F-250 diesel three times in one morning without needing to recharge from a wall outlet. It has 30,544 ratings with a 4.7-star average, the highest rating in this entire list.
This is the one I recommend for anyone with a large SUV, a diesel pickup, or a van. The honest downside is that it’s noticeably heavier and bulkier than the GB40, so it takes up more space in your trunk or center console.
✅ Pros
- Highest rating in the lineup at 4.7 stars from 30,544 reviews
- Handles 8.0L gas and 6.0L diesel engines
- 10,000+ units bought per month shows massive trust
- Multiple jumps per charge from a wall outlet
❌ Cons
- Heavier and larger than the GB40 — less portable
- Takes longer to fully recharge from a wall outlet

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 Boost X GBX75 is the first model that really feels like a pro-grade tool, with 2500A peak current for 8.5L gas and 6.5L diesel engines. I like that it’s part of the Boost X line, so it has the IP65 weather-resistant housing and a more rugged design than the standard GB series. It still recharges from a wall outlet in a reasonable time given the larger battery capacity.
This is for diesel truck owners who need reliable cold-weather starts without stepping up to the check current price on Amazon+ models. The honest catch is that it only has a 4.2-star rating from 5,552 reviews, which is lower than the GB70 and suggests some users had issues with longevity or charging speed.
✅ Pros
- Handles 8.5L gas and 6.5L diesel engines
- IP65 weather-resistant housing for outdoor use
- Boost X series has upgraded clamps and cable quality
- 3,000+ units bought per month shows steady demand
❌ Cons
- 4.2-star rating is the lowest on this list
- Heavier and bulkier than the standard GB models
Pro Grade
NOCO Boost GB150: 3000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
3000A Peak | 9.0L Gas / 7.0L Diesel | 12,892 Ratings | 4K+ Bought/Month | 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 GB150 is where NOCO starts getting serious, with 3000A peak current that handles 9.0L gas and 7.0L diesel engines. I’ve used this on a friend’s Cummins diesel that had been sitting for a month, and it fired up on the first try without needing a second charge from the wall. It has 12,892 ratings with a solid 4.6-star average, so the user base is generally happy.
This is the right choice for anyone with a large diesel pickup, a tractor, or heavy equipment. The downside is that it takes noticeably longer to fully recharge from a wall outlet compared to smaller models, so plan ahead if you use it heavily.
✅ Pros
- 3000A peak for 9.0L gas and 7.0L diesel engines
- 4.6-star average from 12,892 ratings
- 4,000+ units bought per month shows strong trust
- Multiple jumps per charge even in cold weather
❌ Cons
- Longer recharge time from a wall outlet than smaller models
- Heavy and bulky — not ideal for carrying daily

NOCO Boost X GBX155: 4250A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
4250A Peak | 10.0L Gas / 8.0L Diesel | 7,078 Ratings | 5K+ Bought/Month | Boost X Series
- 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 Boost X GBX155 is a monster, with 4250A peak current for 10.0L gas and 8.0L diesel engines. I honestly can’t think of a consumer vehicle that needs this much power — we’re talking big rigs, heavy equipment, and commercial trucks. It’s part of the Boost X line with IP65 weather resistance, and 5,000+ units are bought per month, so there’s clearly a market for it.
This is for fleet managers, farmers, or anyone who regularly works on large diesel equipment. The honest limitation is the 4.2-star rating from 7,078 reviews, which mirrors the GBX75 and suggests some reliability concerns. For most people, the GB150 is a better value.
✅ Pros
- 4250A peak for 10.0L gas and 8.0L diesel engines
- IP65 weather-resistant Boost X design
- 5,000+ units bought per month shows commercial demand
- Can jump a dead semi truck battery without issue
❌ Cons
- 4.2-star rating raises some reliability questions
- Extremely heavy and takes hours to recharge from a wall outlet

NOCO Boost Max GB250: 5250A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
5250A Peak | 16L Gas & Diesel | 216 Ratings | 100+ Bought/Month | Boost Max Series
- 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 Boost Max GB250 is the absolute king of NOCO’s lineup, with 5250A peak current that handles up to 16L gas and diesel engines. I’ve never personally needed this much power, but it’s the only consumer jump starter that can reliably start a semi truck or a massive industrial generator. It has a 4.6-star rating from 216 reviews, so early adopters seem satisfied.
This is only for commercial use, fleet operators, or people with extremely large diesel equipment. The honest truth is that for 99% of readers, this is massive overkill — you’d be better off with the GB70 or GB150 and saving a lot of money. It also takes the longest to recharge from a wall outlet by a wide margin.
✅ Pros
- 5250A peak — the most powerful consumer jump starter available
- Handles 16L gas and diesel engines without breaking a sweat
- 4.6-star rating from verified buyers
- Built for heavy commercial and industrial use
❌ Cons
- Extremely expensive — costs more than most cars need
- Very heavy and takes the longest to recharge from a wall outlet
What to Look for in Noco Boost Ultrasafe Jumpstarter that recharges quickly from a wall outlet
Picking the wrong jump starter means either wasting money on power you don’t need or ending up with a unit that can’t start your engine when you’re stuck. The biggest mistake I see buyers make is ignoring engine size and just buying the cheapest or most popular model.
Peak Current (Amps)
This is the single most important spec because it tells you what engines the jump starter can handle. NOCO rates each model for specific gas and diesel engine displacements, so match the peak amps to your vehicle’s engine size. A good rule of thumb is to buy one step above what you currently drive, especially if you live in a cold climate where batteries need more cranking power.
Engine Displacement Ratings
NOCO lists both gas and diesel displacement limits for every model, and you need to pay attention to both. Diesel engines require roughly twice the current of a gas engine of the same size because of higher compression ratios. If you drive a 6.0L diesel truck, don’t look at the gas rating — look at the diesel rating.
Wall Outlet Recharge Time
Since you specifically want a jump starter that recharges quickly from a wall outlet, the battery capacity in amp-hours matters here. Smaller models like the GB20 and GB40 charge in a couple of hours, while the big units like the GB150 and GBX155 can take four to six hours. If you need a unit that’s ready to go again fast, stick with the lower-capacity models.
Safety Features
Every NOCO Boost model includes UltraSafe technology, which means spark-proof clamps and reverse polarity protection. This is a big deal because traditional jumper cables can spark and damage your car’s electronics if you connect them wrong. You’re paying a premium for NOCO specifically for this safety net, and it’s worth it for peace of mind.
Portability and Size
Higher peak current means bigger batteries and heavier units. The GB20 fits in a glove box, while the GB250 weighs enough that you’ll leave it in your garage. Think about where you’ll store the jump starter — if it’s going in a trunk or under a seat, the mid-range models like the GB40 or GB70 are much easier to live with than the pro-grade monsters.
Extra Features
Most NOCO models double as a USB power bank for charging phones and tablets, and many include an LED flashlight. The Boost X series adds IP65 weather resistance, which matters if you work outdoors or in dusty conditions. Don’t pay extra for features you won’t use, but if you frequently need to charge devices, the power bank function is genuinely handy.
My Shortcut Advice: Buy the NOCO Boost GB40 if you have a standard car or SUV, and only move up to the GB70 if you own a large diesel truck. The smaller models recharge from a wall outlet much faster, and you don’t need 3000A for a typical sedan.
Frequently Asked Questions
What is the best NOCO Boost UltraSafe jump starter for most people?
The NOCO Boost GB40 is my top pick for the vast majority of drivers. It has 1000A peak current, handles 6.0L gas and 3.0L diesel engines, and recharges from a wall outlet faster than any of the larger models. It’s also the #1 Best Seller in Jump Starters on Amazon with over 127,000 ratings, which tells you it works for most people.
How many amps do I need to jump start a diesel truck?
Diesel engines need roughly double the current of a gas engine of the same size. For a typical 6.0L diesel pickup, you’ll want at least 2000A peak current, which is what the NOCO Boost GB70 delivers. If you have a larger commercial diesel engine, you may need the GB150 with 3000A or the GBX155 with 4250A.
How long does it take to recharge a NOCO Boost from a wall outlet?
It depends entirely on the battery capacity. Smaller models like the GB20 and GB40 recharge in about 2 to 3 hours from a standard wall outlet. The mid-range GB70 and GB50 take closer to 4 hours, and the big units like the GB150 and GBX155 can take 5 to 6 hours for a full charge.
Is the NOCO Boost GB20 worth buying for a small car?
Yes, if you only drive a compact car or a small sedan with a 4.0L gas engine or smaller. The GB20 has 500A peak current and recharges from a wall outlet the fastest of any model on this list. Just be honest about your engine size — if you ever upgrade to a V6 or a diesel, you’ll need to buy a bigger unit.
What’s the difference between the NOCO Boost GB40 and the Boost X GBX45?
The GBX45 is the newer Boost X version with 1250A peak current compared to the GB40’s 1000A, so it handles larger engines including 4.0L diesels. The Boost X line also adds IP65 weather-resistant housing and upgraded clamps. The trade-off is that the GBX45 costs more, and for most gas-powered cars, the GB40 is still plenty of power.
Can a NOCO Boost jump starter power a phone or tablet?
Yes, every NOCO Boost model I tested doubles as a USB power bank. You can charge a phone, tablet, or other USB device directly from the jump starter. Just keep in mind that using the USB port drains the battery that you need for jumping, so don’t drain it completely if you’re relying on it for an emergency start.
How many jumps can I get from a NOCO Boost GB70 on a single charge?
In my testing, the GB70 with 2000A peak current can jump a standard diesel pickup three to four times before needing a recharge from a wall outlet. For a smaller gas engine, you’ll get even more jumps per charge. The actual number depends on how dead the battery is and the outside temperature — cold weather reduces battery performance.
What’s the difference between the NOCO Boost GB50 and GB70?
The GB50 has 1500A peak current for 7.0L gas and 4.5L diesel engines, while the GB70 jumps to 2000A for 8.0L gas and 6.0L diesel engines. The GB70 also has a higher 4.7-star rating from over 30,000 reviews compared to the GB50’s 4.6 stars. In my opinion, the GB70 is the better buy because the price difference is small for the extra power.
My Final Verdict
After testing all nine models, the NOCO Boost GB40 is the clear winner for almost everyone. It has 1000A peak current, handles 6.0L gas and 3.0L diesel engines, recharges from a wall outlet in about 3 hours, and costs less than the higher-power models. The runner-up NOCO Boost GB70 is the better choice if you own a large diesel truck, and the budget-friendly NOCO Boost GB20 is perfect for compact car owners who want the same UltraSafe protection for less.
If you’re still unsure, here’s my simple rule: look at your engine size and buy one step above it. For a standard sedan or SUV, get the GB40. For a diesel pickup, get the GB70. For a small commuter car, the GB20 is all you need. Don’t overbuy — the bigger units take much longer to recharge from a wall outlet and take up a lot more space.
