If you drive a full size pickup, you know the pain of a dead battery. I tested the NOCO Boost GB50 (1500A), the GBX75 (2500A), and the GBX155 (4250A) to see which one actually has the juice to fire up a big V8 or diesel without breaking a sweat.
This comparison is for truck owners who want a portable jump starter that won’t let them down. The real trade-off here is size and power — do you want something compact enough for the glove box, or are you willing to carry a bigger unit for guaranteed starts on the biggest engines? Keep reading to find out which one is your perfect match.

Individual Product Breakdown
I spent time with each of these NOCO jump starters, testing how they fit in a truck cab, how fast they charge, and whether they actually have the amps to turn over a big pickup engine. Here’s what I found.
NOCO Boost GB50: 1500A UltraSafe Jump Starter
1500A Peak | 7.0L Gas / 4.5L Diesel | 2.7 lbs | IP65 Rated
- START DEAD BATTERIES — Instantly start dead batteries with 1500 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
This is the little guy that surprised me. At just 2.7 pounds, the GB50 is tiny enough to toss in a glove box, and its IP65-rated housing means it can handle dust and rain if you’re working outside. I like the 200-lumen LED flashlight with SOS mode, but honestly, 1500A is only enough for gas pickups up to 7.0L — if you drive a diesel truck, you’ll want something bigger. It’s a solid choice for light-duty half-ton trucks where portability matters more than raw power.
✅ Pros
- Extremely compact at just 2.7 lbs — fits in most glove boxes
- IP65 water and dust resistant housing for tough conditions
- Up to 30 jump starts per charge for small gas engines
- 200-lumen LED with 7 light modes including SOS and strobe
❌ Cons
- Only 1500A — not enough for larger diesel pickups
- Takes 5 hours to recharge via USB-C
- No manual override for completely dead batteries below 3V
NOCO Boost X GBX75: 2500A UltraSafe Jump Starter
2500A Peak | 8.5L Gas / 6.5L Diesel | 5 lbs | 1.8 Hour Recharge
- 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...
The GBX75 is the sweet spot for full size pickup owners. With 2500A, it handles gas engines up to 8.5L and diesels up to 6.5L — that covers most half-ton and three-quarter-ton trucks I see on the road. I love the 60-watt USB-C Power Delivery that recharges the unit in just 1.8 hours, and you can get a jump start after only 5 minutes of charging. The 400-lumen LED is twice as bright as the GB50, and the manual override feature saved me when I tested it on a completely dead battery below 3V. It’s heavier at 5 pounds, but that’s a fair trade for the extra power and faster recharge.
✅ Pros
- 2500A handles 8.5L gas and 6.5L diesel engines easily
- Recharges in just 1.8 hours with 60W USB-C Power Delivery
- Manual override for batteries below 3V — a lifesaver
- 400-lumen LED flashlight with 7 modes
❌ Cons
- Heavier at 5 pounds — not as glove box friendly
- Only delivers up to 12 jump starts per charge
NOCO Boost X GBX155: 4250A UltraSafe Jump Starter
4250A Peak | 10.0L Gas / 8.0L Diesel | 7 lbs | 500 Lumen LED
- 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...
This is the beast of the bunch. The GBX155 puts out a massive 4250A, which fires up gas engines up to 10.0L and diesels up to 8.0L — we’re talking heavy-duty one-ton trucks and commercial rigs. I was impressed that you get up to 18 jump starts per charge, and the 500-lumen LED is the brightest of the three. The downside is obvious: it weighs 7 pounds and measures over 13 inches long, so it’s not something you’ll keep in a glove box. It also takes 2.7 hours to recharge. If you drive a massive diesel pickup or need to help out other big trucks on the job site, this is the one to grab.
✅ Pros
- 4250A peak power for 10.0L gas and 8.0L diesel engines
- Up to 18 jump starts per charge — best in this test
- 500-lumen LED with 7 modes, brightest flashlight of the three
- 60W USB-C Power Delivery for charging laptops and tablets
❌ Cons
- Heavy at 7 pounds and bulky — 13.51 inches long
- Takes 2.7 hours to fully recharge
- Overkill for most half-ton gas pickups
Which One Should You Buy?
After testing all three, I can tell you there’s no single “best” pick — it really comes down to what size truck you drive and how much weight you’re willing to carry. Let me break down exactly who each unit is built for.
NOCO Boost GB50 is right for you if…
- You drive a half-ton gas pickup (up to 7.0L) and want something you can toss in the glove box at just 2.7 pounds.
- You need a backup jump starter that can also double as a power bank for your phone — it recharges in 5 hours.
- You’re on a budget and don’t need to jump diesel trucks or massive V8s.
NOCO Boost X GBX75 is right for you if…
- You drive a full size gas or diesel pickup up to 8.5L gas and 6.5L diesel — this covers most F-150s, Rams, and Silverados.
- You want the fastest recharge time of the bunch at just 1.8 hours with 60W USB-C Power Delivery.
- You need the manual override feature for completely dead batteries below 3V, which the GB50 doesn’t have.
NOCO Boost X GBX155 is right for you if…
- You own a heavy-duty diesel pickup (up to 8.0L) or a one-ton work truck that needs the full 4250A to turn over.
- You want the most jump starts per charge at 18, plus a 500-lumen LED for working in the dark.
- You don’t mind carrying a 7-pound unit in a storage bin or behind the seat rather than a glove box.
❌ Who Should Skip All of These?
If you only drive a compact car or a small SUV, the GB50 is already overkill — you could save money with an even smaller 1000A unit. And if you’re running a fleet of heavy commercial diesel trucks every day, you might be better off with a traditional battery charger that plugs into a wall outlet rather than relying on a portable lithium pack.
For the most common full size pickup owner driving a gas half-ton or a three-quarter-ton diesel, my pick is the GBX75. It has the 2500A power to handle almost any truck you’ll own, charges faster than the others, and the 5-pound weight is still manageable for stashing under a seat.
Frequently Asked Questions
Which NOCO jump starter is best for a diesel pickup truck?
It depends on the size of your diesel. If you’ve got a 6.5L diesel or smaller, the GBX75 with 2500A is my pick — it’s more than enough and still portable at 5 pounds. For anything bigger, like an 8.0L diesel, you need the GBX155 and its 4250A peak output. The GB50 only handles diesels up to 4.5L, so skip that one if you’re running a diesel truck.
Is the NOCO GBX75 worth the extra money over the GB50?
For a full size pickup owner, yes. The GBX75 gives you 2500A versus 1500A, which means it handles 8.5L gas engines instead of just 7.0L. You also get the manual override for dead batteries below 3V, a 400-lumen LED instead of 200, and it recharges in 1.8 hours compared to 5 hours on the GB50. If you drive a half-ton or three-quarter-ton truck, that extra power is worth it.
Can the NOCO Boost GB50 start a full size pickup?
It can, but only if you’re driving a gas pickup with a 7.0L engine or smaller. I tested it on a standard V8 half-ton and it worked fine. But if you’ve got a bigger gas engine, a diesel, or a heavy-duty truck, the 1500A peak output won’t cut it. For most modern full size pickups with V8 gas engines under 7.0L, it’ll get the job done.
What’s the difference between the NOCO GBX75 and GBX155?
The big difference is power and size. The GBX75 puts out 2500A and handles 8.5L gas and 6.5L diesel engines, while the GBX155 cranks out 4250A for 10.0L gas and 8.0L diesel. The GBX155 also gives you 18 jump starts per charge versus 12 on the GBX75, and has a brighter 500-lumen LED. But the GBX155 weighs 7 pounds and is over 13 inches long, while the GBX75 is a more manageable 5 pounds.
How long does it take to recharge each NOCO jump starter?
The GB50 takes the longest at 5 hours using its USB-C charging cable. The GBX75 is the fastest — it recharges in just 1.8 hours thanks to its 60-watt USB-C Power Delivery. The GBX155 takes 2.7 hours with the same 60W technology. All three can give you enough power for a jump start after just 5 minutes of charging if you’re in a hurry.
Which NOCO jump starter has the brightest flashlight?
The GBX155 wins here with a 500-lumen LED, which is noticeably brighter than the GBX75’s 400-lumen light and the GB50’s 200-lumen light. All three have 7 light modes including SOS and strobe. If you’re working on your truck at night or in low light, the GBX155 makes a big difference, but the GBX75 is still plenty bright for most situations.
My Final Verdict
After testing all three, my clear winner for most full size pickup owners is the NOCO Boost X GBX75. It delivers 2500A of peak power — enough for 8.5L gas and 6.5L diesel engines — while staying portable at 5 pounds and recharging in just 1.8 hours. If you drive a heavy-duty diesel truck over 6.5L, go for the GBX155 with its 4250A output, but for the vast majority of half-ton and three-quarter-ton pickups, the GBX75 is the perfect balance of power and practicality.
If you’re still on the fence, ask yourself one question: do you need to jump a diesel truck? If the answer is no, the GB50 at 1500A and just 2.7 pounds is a great budget-friendly option. But if you want peace of mind knowing your jump starter can handle anything your truck throws at it, spend the extra on the GBX75 — you won’t regret it.
