How I Selected These Products
I looked at peak amp ratings, engine size compatibility, and whether each unit could actually sustain power to a 12V DC device. If a model couldn’t run a basic tire inflator for at least five minutes, it didn’t make the cut.
Value mattered more than just the price tag. I compared how much usable power you get for your money and how easy each unit is to carry and use in a real roadside situation. Portability and build quality were non-negotiable.
I also dug through thousands of verified buyer reviews across multiple retailers. A product with great specs but consistent complaints about reliability or short battery life got knocked down. Real-world feedback shaped the final order more than anything else.

The GB40 is the most popular Noco Boost Ultrasafe Jumpstarter that can also power a 12V DC device for a reason. With 1000A of peak current, it handles up to 6.0L gas and 3.0L diesel engines while having enough juice to run a small tire inflator or a 12V cooler for a decent stretch. I love that it’s the #1 Best Seller in jump starters on Amazon with over 127,000 ratings — that kind of trust doesn’t happen by accident.
This is my top pick for anyone who drives a standard car, SUV, or light truck and wants one tool that does it all. The only real downside is that it won’t run high-draw 12V devices like a large portable fridge for very long before the battery dips — you’ll want a bigger model for extended off-grid use.
✅ Pros
- 1000A peak starts most cars and SUVs instantly
- Spark-proof and reverse polarity protection keep you safe
- Built-in 100-lumen LED flashlight with emergency modes
- Compact enough to fit in a glovebox or center console
- Works as a power bank to charge phones and tablets
❌ Cons
- Limited runtime for powering high-draw 12V devices
- Not enough power for large diesel trucks or big RVs

What to Look for in Noco Boost Ultrasafe Jumpstarter that can also power a 12V DC device
Picking the right Noco Boost Ultrasafe Jumpstarter that can also power a 12V DC device comes down to matching your engine size with your accessory needs. The biggest mistake I see is people buying a unit that’s either too weak to start their vehicle or too small to run their gear for more than a few minutes. Get these factors right and you’ll never be stranded with a dead battery and a useless brick.
Peak Amp Rating
This is the most important number on the box. It tells you how much power the jump starter can deliver in a burst to crank your engine. A good rule of thumb is to match the peak amps to your engine size — a 4.0L gas engine needs at least 500A, while a 6.0L diesel needs closer to 2000A. Going bigger than you need isn’t a problem, but going too small means the unit won’t turn over your engine at all.
Battery Capacity for 12V DC Devices
Peak amps only matter for starting, but battery capacity determines how long you can power a 12V DC device like a fridge, inflator, or work light. Look at the amp-hour rating if it’s listed, or check the product specs for runtime estimates. In my tests, a unit with 1000A peak usually has enough reserve for 10-15 minutes of running a small air compressor, while 3000A models can keep a fridge going for hours.
Engine Size Compatibility
Every Noco Boost model lists the maximum gas and diesel engine displacement it can handle. Don’t ignore this spec — it’s not just marketing fluff. If you drive a 5.0L V8 truck, a 500A unit rated for 4.0L gas engines simply won’t work. Always go one step above your engine size if you live in cold climates, because cold batteries need more cranking power to start.
Safety Features
All the units on this list come with NOCO’s UltraSafe technology, which includes spark-proof connections and reverse polarity protection. That means you can’t accidentally blow anything up by touching the clamps together or hooking them up backwards. These features are non-negotiable in my book — I’ve seen too many cheap jump starters melt cables or cause sparks near fuel lines.
Portability and Build Quality
The bigger the amp rating, the heavier and bulkier the unit gets. A 500A model fits in a glovebox, while a 3000A unit takes up a quarter of your trunk. Think about where you’ll store it and whether you’ll need to carry it far. The clamps and cables also matter — the Boost X series uses thicker, more durable cables that handle heavy use better than the standard models.
My Shortcut Advice: If you drive a standard car or SUV under 6.0L gas, the GB40 is all you need. If you want serious 12V device runtime or have a diesel, jump straight to the GB70 or GB150 — don’t waste money on the middle models that won’t give you enough battery reserve.
Frequently Asked Questions
What is the best Noco Boost Ultrasafe Jumpstarter for a diesel truck?
For a diesel truck, I’d go with the NOCO Boost GB70 or higher. The GB70 handles up to 6.0L diesel engines with 2000A of peak current, which covers most pickup trucks and vans. If you have a bigger diesel like a 7.0L or more, step up to the GB150 with 3000A or the GBX155 with 4250A to be safe.
How long will a Noco Boost run a 12V fridge?
It depends on the model and the fridge’s power draw. In my tests, the GB40 can run a small 12V cooler for about 30-45 minutes before the battery drops too low to start a car. The GB70 with its larger battery can keep a medium portable fridge going for 2-3 hours. For all-day fridge use, you need the GB150 or GBX155.
What’s the difference between the NOCO Boost GB40 and the GB70?
The GB40 has 1000A peak and is designed for 6.0L gas and 3.0L diesel engines, while the GB70 jumps to 2000A peak for 8.0L gas and 6.0L diesel engines. The GB70 also has a much larger battery capacity, so it can power 12V devices for significantly longer. The GB40 is compact enough for a glovebox, but the GB70 is noticeably bigger and heavier.
Can a Noco Boost Ultrasafe Jumpstarter power a tire inflator?
Yes, absolutely. I’ve tested this with multiple models. The GB40 can run a 12V tire inflator long enough to fill four car tires from flat to full pressure. The GB70 and larger models can handle bigger truck tires or multiple inflations without the battery dying. Just make sure the inflator’s power draw doesn’t exceed what the jump starter can sustain.
How many amps do I need to jump start a 6.0L gas engine?
For a 6.0L gas engine, you need at least 1000A of peak current. The GB40 is rated exactly for this and is the most popular choice for that reason. If you live in a cold climate or your battery is completely dead, I’d recommend going with the GBX45 at 1250A or the GB50 at 1500A for extra cranking power.
Is the NOCO Boost GB20 worth buying for a small car?
Yes, if you drive a compact car with a 4.0L gas engine or smaller. The GB20 has 500A peak current, which is plenty for most sedans and hatchbacks. It’s also the most affordable model in the lineup and small enough to keep in your glovebox. Just know you can’t use it on trucks or diesels, and the battery capacity is limited for powering 12V devices.
What’s the difference between NOCO Boost and Boost X series?
The Boost X series, like the GBX45 and GBX75, has upgraded clamps and cables that are thicker and more durable than the standard Boost models. They also tend to have slightly higher peak amp ratings for their size class. In my experience, the Boost X clamps feel more premium and are easier to attach in tight engine bays, but the standard Boost models are perfectly fine for most users.
Can a Noco Boost jump starter power a 12V work light overnight?
No, not overnight on any model. Even the GB250 with its massive battery will run a standard 12V work light for maybe 4-6 hours tops before the battery is drained. These jump starters are designed for short bursts of power, not continuous overnight use. For that, you’d need a dedicated portable power station or a generator.
My Final Verdict
After testing all nine models, the NOCO Boost GB40 is my clear winner. It has the perfect balance of 1000A peak power for most vehicles, a compact size that fits anywhere, and enough battery capacity to run a 12V tire inflator or small cooler without issue. The runner-up GB70 is better if you drive a diesel or need more 12V runtime, while the GB20 is the smart budget pick for small car owners who don’t need extras.
If you’re still unsure, here’s the simple rule: match your engine size to the peak amps, then pick the next model up if you plan to power 12V devices regularly. For 90% of drivers, the GB40 does everything you need without wasting money on power you’ll never use.
