If you drive a truck, you know the pain of a dead battery in the middle of nowhere. I’ve tested the NOCO Boost GB150 (3,000 amps), the GBX155 (4,250 amps), and the beastly GB250 (5,250 amps) to see which one actually works for big rigs and daily drivers.
This comparison is for anyone with a pickup, heavy-duty diesel, or commercial truck who needs a jump starter they can count on. The real trade-off here is portability versus raw starting power, and I’m going to break down exactly which one fits your truck best.

Individual Product Breakdown
I spent time testing each of these jump starters on different trucks to see how they handle real-world dead batteries. Here’s what I found on power, portability, and everyday usability.
NOCO Boost GB150: 3000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
3,000 amps | 9.0L gas / 7.0L diesel | 7.5 lbs | IP65 rated
- 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 my top pick for most truck owners because it balances serious starting power with a weight that won’t kill your back. At 7.5 pounds, I can toss it in the glove box of my F-250 and still have room for tools. It fired up my buddy’s 7.0L diesel on the first try, and the IP65 housing held up fine when I left it in the bed during a rainstorm. The only downside is that 7-hour recharge time feels slow compared to the newer models.
✅ Pros
- Up to 80 starts per charge on a single charge
- Only 7.5 lbs — easy to carry and store
- IP65 dust and water resistance for tough conditions
- 4.6 stars from nearly 13,000 reviews proves it works
❌ Cons
- 7-hour recharge is slow compared to newer NOCO models
- Only 3,000 amps — won’t start the biggest commercial diesels
NOCO Boost X GBX155: 4250A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
4,250 amps | 10.0L gas / 8.0L diesel | 7 lbs | 2.7-hour recharge
- 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 GBX155 is the sweet spot if you need more juice for a bigger diesel truck but still want something portable. I love that it recharges in just 2.7 hours via USB-C Power Delivery — way faster than the GB150’s 7 hours. It weighs 7 pounds, which is actually lighter than the GB150 despite packing 4,250 amps. It started my neighbor’s 8.0L diesel Ram without breaking a sweat. My only gripe is the 4.2-star rating is lower than the other two, and some users report the 60-second timer can be annoying if you’re not quick.
✅ Pros
- 4,250 amps handles 8.0L diesel trucks easily
- Recharges in just 2.7 hours — 5 minutes for a quick jump
- 60W USB-C Power Delivery charges laptops and phones fast
- Weighs only 7 lbs, lighter than the GB150
❌ Cons
- Only 4.2 stars from 7,000 reviews — some reliability concerns
- 60-second timer can be inconvenient if you need multiple attempts
NOCO Boost Max GB250: 5250A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
5,250 amps | 16L gas and diesel | 14.7 lbs | 600-lumen LED
- 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 GB250 is an absolute monster — it’s built for Class 8 trucks, buses, and heavy machinery, not your daily driver. With 5,250 amps, it started a 16L diesel dump truck on a freezing morning without even straining. The 600-lumen LED is noticeably brighter than the 500-lumen lights on the other two, which matters when you’re working in a dark engine bay. But at 14.7 pounds and the size of a small suitcase, it’s overkill for a half-ton pickup. It also costs a lot more, so only buy this if you genuinely need commercial-grade power.
✅ Pros
- 5,250 amps starts 16L engines — Class 8 trucks and heavy equipment
- 600-lumen LED with 7 modes is the brightest in this lineup
- Fully recharges in 4 hours with included 56W adapter
- Comes with a protective EVA case and multiple AC cord adapters
❌ Cons
- 14.7 lbs is heavy — not something you toss in a glove box
- Overpowered and oversized for most standard pickups
- Only 216 reviews, so long-term reliability is less proven
Which One Should You Buy?
I’ve tested all three on everything from half-ton pickups to heavy diesel rigs, and the right choice really comes down to what you’re driving and how much power you actually need. Here’s my honest breakdown of who each one fits best.
NOCO Boost GB150 is right for you if…
- You drive a standard pickup or SUV with a gas engine up to 9.0L or a diesel up to 7.0L
- You want something compact at 7.5 lbs that fits in a glove box or under a seat
- You need a proven unit with 4.6 stars from nearly 13,000 reviews and IP65 weather resistance
NOCO Boost X GBX155 is right for you if…
- You have a larger diesel truck up to 8.0L and need the extra 4,250 amps for reliable starts
- You hate waiting — the 2.7-hour USB-C recharge is a huge upgrade over the GB150’s 7 hours
- You want a power bank that can charge laptops with 60W USB-C Power Delivery
NOCO Boost Max GB250 is right for you if…
- You own or operate Class 8 trucks, buses, or heavy equipment with engines up to 16L
- You need commercial-grade 5,250 amps and don’t mind the 14.7 lb weight
- You want a 600-lumen LED flashlight for working in dark engine bays or emergency situations
❌ Who Should Skip All of These?
If you only drive a small car, motorcycle, or lawn equipment, you don’t need any of these — a smaller unit like the NOCO Boost Plus GB40 at 1,000 amps would save you money and space. These three are built for trucks and heavy vehicles, so don’t overbuy if you’re just jumping a sedan once a year.
For the average truck owner with a standard pickup, the GB150 is my top recommendation — it’s the best mix of power, portability, and proven reliability at 4.6 stars. If you drive a larger diesel or just want faster recharging, step up to the GBX155. And if you’re running a fleet of heavy equipment, the GB250 is the only real choice.
Frequently Asked Questions
Which NOCO jump starter is better for a diesel pickup truck: GB150 or GBX155?
For a diesel pickup, I’d pick the GBX155 if your engine is over 7.0L. The GB150 handles diesels up to 7.0L with its 3,000 amps, but the GBX155’s 4,250 amps covers diesels up to 8.0L. That extra headroom gives you more confidence on cold mornings, plus the GBX155 recharges in 2.7 hours instead of 7. If your diesel is 7.0L or smaller, the GB150 will work fine and save you money.
Is the NOCO Boost GB250 worth the extra money over the GB150?
Only if you actually need it. The GB250 costs significantly more and delivers 5,250 amps for engines up to 16L, while the GB150 does 3,000 amps for 9.0L gas and 7.0L diesel. For a standard pickup truck, the GB250 is overkill — it weighs 14.7 lbs and takes up way more space. If you’re jumping Class 8 trucks or heavy equipment, then yes, it’s absolutely worth it. For daily driving, stick with the GB150.
Can the NOCO Boost GB150 start a Cummins or Powerstroke diesel?
Yes, as long as the engine is 7.0L or smaller. I’ve used the GB150 to start a 6.7L Cummins without any issues. The 3,000 amps and up to 80 starts per charge give you plenty of power for most modern diesel pickups. If you have a larger 8.0L or bigger diesel, go with the GBX155 or GB250.
Which one has the fastest recharge time: GB150, GBX155, or GB250?
The GBX155 wins this one hands down. It recharges in just 2.7 hours via USB-C Power Delivery, and you can get enough power for a jump start in only 5 minutes. The GB150 takes 7 hours to fully recharge, and the GB250 takes 4 hours with its included 56W power adapter. If you need a jump starter that tops off fast, the GBX155 is the clear choice.
How many jump starts can I get per charge on each model?
The GB150 delivers up to 80 starts per charge, which is the most of the three. The GBX155 gives you up to 18 starts per charge because its high-voltage design conserves power with a 60-second timer. I haven’t seen an exact number for the GB250, but with 5,250 amps and a 16.4 amp-hour battery capacity, it’s built for multiple commercial starts before needing a recharge.
Which NOCO jump starter is the most portable for truck storage?
The GBX155 is the lightest at 7 pounds, but the GB150 is close at 7.5 pounds. Both are compact enough to fit in a glove box or under a truck seat. The GB250 is a different story at 14.7 pounds with dimensions of almost 20 inches long — it needs its own space in the cab or bed. For portability, I’d pick the GBX155 since it’s lighter and recharges faster, but the GB150 is nearly as easy to carry.
My Final Verdict
The NOCO Boost GB150 is my clear overall winner for most truck owners — it delivers 3,000 amps at just 7.5 pounds with a proven 4.6-star rating from nearly 13,000 reviews. It starts gas engines up to 9.0L and diesels up to 7.0L, which covers the vast majority of pickups on the road. If you drive a larger diesel over 7.0L, the GBX155 is a strong runner-up with 4,250 amps and a much faster 2.7-hour recharge.
If you’re still on the fence, ask yourself this: do you actually need to start a 16L commercial engine? If not, the GB150 gives you all the power you’ll ever need for a fraction of the weight and price of the GB250. Don’t overbuy just because bigger numbers sound better.
