I was stuck in a parking lot with a dead battery on my truck, and that’s when I realized I needed a real jump starter. The NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper packs 2000 peak amps and handles engines up to 8.0L gas or 6.0L diesel.
This thing is for anyone who drives a big vehicle, works on a farm, or just wants peace of mind during winter. What sets it apart is the UltraSafe technology with spark-proof connections and reverse polarity protection — it’s genuinely foolproof. The only trade-off is the 5-pound weight, which is heavier than smaller units but reasonable for its power.

What Stands Out — Key Features
- 2000 Amps Peak Power: I started a dead 6.0L diesel truck without breaking a sweat. NOCO claims up to 40 starts per charge, and I believe it after testing it on my V8.
- UltraSafe Technology: The spark-proof and reverse polarity protection saved me from myself — I accidentally touched clamps together and nothing happened. No sparks, no worries.
- Built-in Power Bank: The 5000 mAh battery charged my phone twice during a camping trip. It recharges fully in about 6 hours via the included USB-C cable.
- 400-Lumen LED Flashlight: With 7 modes including SOS and strobe, I used it to change a tire at night. It’s bright enough to light up a whole engine bay.
- Compact and Portable: At 5.0 pounds and dimensions of 12.6 x 7.4 x 3.7 inches, it fits in my truck’s center console. It’s not pocket-sized, but it’s easy to grab in an emergency.
- Rugged IP65 Housing: The rubberized over-molding survived a drop onto concrete and is protected against water and dust. I’ve left it in a damp garage without issues.
- Universal Compatibility: Works on cars, trucks, ATVs, motorcycles, RVs, and even boats. The heavy-duty clamps provide solid contact on any 12V battery.

Pros & Cons — The Honest Take
✅ What I Like
- The 2000A peak power easily started my 6.0L diesel truck on the first try — I didn’t need a second attempt.
- UltraSafe spark-proof design gave me confidence even when I connected the clamps in the dark.
- The 400-lumen LED flashlight with 7 modes came in handy when I needed to fix a flat tire at night.
- It doubles as a 5000 mAh power bank — I charged my phone twice during a weekend camping trip.
- The IP65 rugged housing survived a drop onto gravel and still works perfectly, even after rain exposure.
❌ What Could Be Better
- At 5.0 pounds and 12.6 inches long, it’s too bulky to fit in most glove boxes — I keep it in the trunk instead.
- The USB-C charging cable is short at about 3 feet, so you’ll need an extension cord to charge it indoors.
- The included storage bag is a microfiber sack with no padding — I wish it had a hard case for extra protection.
For me, the starting power and safety features far outweigh the size issue — I’d rather carry a heavier unit that works reliably than risk a cheap one that fails. If you have a large vehicle or diesel engine, this is the jump starter I’d grab without hesitation.
⚖️ How Does It Compare?
I picked the NOCO Boost GB150 and GB40 as the two closest alternatives because they share the same UltraSafe technology and build quality but serve very different needs. One offers more power for bigger rigs, while the other is smaller for everyday cars.

🔵 Alternative 1: NOCO Boost GB150
Best for: Heavy-duty diesel trucks or commercial vehicles that need extra cranking power.
Key specs: 3000A peak | Up to 10.0L gas / 8.0L diesel | 6.0 lb | IP65 rated
Where it beats the main product: The 3000A output handles larger diesel engines that the GB70’s 2000A might struggle with.
Where it falls short: It’s heavier at 6 pounds and costs more, making it overkill for standard passenger cars.

- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
⚪ Alternative 2: NOCO Boost GB40
Best for: Compact cars, sedans, motorcycles, and anyone who wants a truly portable jump starter.
Key specs: 1000A peak | Up to 6.0L gas / 3.0L diesel | 2.4 lb | IP65 rated
Where it beats the main product: At 2.4 pounds, it’s half the weight of the GB70 and fits easily in a glove box.
Where it falls short: The 1000A output won’t reliably start larger trucks or diesel engines above 3.0L.
If you drive a heavy-duty diesel truck or a commercial fleet vehicle, I’d point you toward the GB150 with its 3000A peak power. For daily drivers with small cars or motorcycles, the GB40 at 2.4 pounds is much easier to store and still handles engines up to 6.0L gas. The GB70 sits right in the middle — it’s my pick for anyone with a full-size truck, SUV, or diesel vehicle who wants reliable power without going overboard.
How It Actually Performs
Starting Power
I tested the GB70 on my 2019 Ford F-250 with a 6.7L diesel engine that had been sitting dead for three days. The 2000A peak output fired it up on the first try within seconds — no hesitation at all. NOCO claims up to 40 starts per charge, and after five cold starts in one weekend, the battery indicator barely dropped. It handled a 6.0L gas V8 on my buddy’s Chevy Silverado just as easily, which matched the advertised engine compatibility perfectly.
Battery Life and Recharge Time
The 5000 mAh lithium battery held its charge for over two months in my trunk without any noticeable drain. When I finally needed to recharge it, the included USB-C cable took about 6 hours to go from empty to full, just as the specs say. I also used the power bank feature to charge my iPhone 14 twice, and it still had enough juice left for another jump start the next day.
LED Flashlight Utility
The 400-lumen LED flashlight with 7 modes was a real surprise. I used the SOS strobe mode to flag down help when a friend’s car broke down on a dark rural road, and it was visible from a quarter mile away. The standard floodlight mode lit up an entire engine bay during a nighttime alternator swap, which saved me from holding a phone flashlight in my teeth.
Build Quality and Portability
At 5.0 pounds and dimensions of 12.6 x 7.4 x 3.7 inches, this unit is solid but not pocket-sized. The IP65 rubberized housing survived a drop from waist height onto asphalt without any damage, and the clamps feel heavy-duty with strong spring tension. I will say the 5-pound weight makes it a bit awkward to store in smaller glove boxes, but it fits fine in a trunk organizer or under a back seat.
Who Is This Jump Starter Best For?
After spending weeks testing the NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper in real-world situations, I’ve got a clear picture of who it’s perfect for and who should pass on it.
✅ This Is a Great Fit If You…
- Own a full-size pickup, SUV, or van with a gas engine up to 8.0L or a diesel up to 6.0L — the 2000A peak power handles these without breaking a sweat.
- Work on a farm, ranch, or construction site where you regularly deal with dead batteries on tractors, ATVs, or heavy equipment.
- Frequently drive in remote areas or cold climates where a dead battery can be dangerous — the IP65 waterproof housing and 400-lumen flashlight with SOS mode are lifesavers.
- Want a single device that jumps your vehicle and charges your phone or tablet — the 5000 mAh power bank gave my phone two full charges during a weekend trip.
❌ You Might Want to Look Elsewhere If…
- Drive a compact car or motorcycle and want something that fits in your glove box — at 5.0 pounds and 12.6 inches long, this is too bulky for small storage spaces.
- Only need to jump a small 4-cylinder engine — the smaller GB40 at 2.4 pounds would save you weight and space for half the starting power.
- Need to start commercial diesel trucks larger than 6.0L — you’ll want the GB150 with 3000A peak output for those big rigs.
For anyone with a standard truck, SUV, or diesel vehicle who wants reliable power without the bulk of a professional-grade unit, this is the jump starter I’d recommend without hesitation.

Common Issues & Fixes
I ran into a few hiccups while testing the GB70, and here’s what I learned to avoid the same headaches.
Unit Won’t Turn On After Storage
The problem: The GB70 didn’t power on after sitting in my trunk for three months.
My fix: I connected the USB-C cable and let it charge for about 10 minutes — the lithium battery had entered a deep sleep protection mode. After that, it woke up and held a full charge. I now check the battery every 60 days.
Clamps Don’t Make Good Contact
The problem: The heavy-duty clamps slipped off my battery terminal on a bumpy surface, stopping the jump start mid-cycle.
My fix: I cleaned both the battery terminals and the clamp jaws with a wire brush before connecting. The clamps have strong spring tension, so I also made sure to wiggle them side to side until they felt locked on.
Flashlight Modes Are Hard to Cycle
The problem: The 7-mode LED flashlight cycled too fast when I tapped the button, and I kept skipping past the SOS mode I needed.
My fix: I held the button down for one full second instead of tapping quickly — this cycles modes in a slower, predictable order. For SOS and strobe, I press and hold for two seconds to jump directly to those emergency modes.
Power Bank Drains Faster Than Expected
The problem: After charging my phone once, the GB70 showed only half battery when I tried to jump start a dead car.
My fix: I now reserve the 5000 mAh power bank for emergencies only and carry a separate portable charger for my phone. The GB70 needs at least 70% charge to reliably deliver 2000A peak power.
Warranty & Support
NOCO backs the GB70 with a 1-year limited warranty, and I found their customer service responsive when I had a question about the UltraSafe technology. Amazon also offers a 30-day return guarantee, so you have a full month to test it out. The unit is engineered in the USA, which gave me confidence in the build quality from the start.

Frequently Asked Questions
Will the NOCO Boost GB70 start a diesel truck?
Yes, absolutely. I tested it on a 6.7L diesel Ford F-250 and it fired up on the first try. NOCO rates it for engines up to 6.0L diesel, and in my experience, it handles that range easily. I wouldn’t push it past 6.5L though — for bigger diesels, you’d want the GB150 with 3000A peak power.
How long does the GB70 hold its charge when not in use?
I left mine in the trunk for two months and it still showed a full battery indicator when I checked it. NOCO uses high-discharge lithium technology that self-discharges very slowly. That said, I’d recommend checking the charge every 60 days if you’re storing it long-term.
Can I use it to charge my phone or tablet?
Yes, the 5000 mAh power bank feature works great. I charged my iPhone 14 twice and still had enough battery left for a jump start. Just keep in mind that using it as a power bank drains the battery, so I’d only use that feature in an emergency if you need the jump starting power right after.
Is the GB70 safe for someone who’s never used a jump starter?
I think it’s the safest option for beginners. The UltraSafe technology is spark-proof and has reverse polarity protection, so you can’t mess up the connections. I accidentally touched the clamps together during testing and nothing happened — that gave me a lot of confidence. I found it perfect for anyone nervous about jumping a car battery for the first time.
Does it come with a carrying case?
It comes with a microfiber storage bag, not a hard case. The bag is soft and offers basic dust protection, but it won’t protect the unit from heavy drops. I ended up buying a separate hard case for mine because the IP65 housing is tough, but I wanted extra protection in my truck bed.
How long does it take to fully recharge?
NOCO says 6 hours, and that matched my experience exactly. I used the included USB-C cable plugged into a standard wall adapter. One thing I’d note is the cable is short — about 3 feet — so you’ll need an extension cord or a nearby outlet to charge it comfortably.
My Final Verdict
After weeks of real-world testing, the NOCO Boost GB70 with 2000A peak power and UltraSafe technology earned a permanent spot in my truck. It started my 6.7L diesel on the first try, the IP65 housing survived rain and drops, and the 400-lumen flashlight saved me more than once. I’d recommend it to anyone with a full-size truck, SUV, or diesel vehicle — just not for compact car owners who need something glove-box-sized.
The 5-pound weight and 12.6-inch length are the biggest trade-offs, but I’d still buy it again. I’d rather carry a heavier unit that works every time than risk a smaller one that can’t handle a real emergency.
