If you drive a pickup truck, you know the pain of a dead battery in the middle of nowhere. I’ve tested the NOCO Boost GB50 with 1500A for engines up to 7.0L gas and the NOCO Boost X GBX75 with 2500A that handles 8.5L gas engines — and the difference matters more than you think.
This comparison is for truck owners who need a jump starter that won’t quit on a cold morning or a long job site. The real trade-off here is portability versus raw power, and I’m going to show you which one fits your rig best.

The biggest difference I see is the GBX75’s 400-lumen LED and 1.8-hour recharge time versus the GB50’s 200-lumen light and 5-hour charge — that’s a massive gap if you’re working after dark.
Individual Product Breakdown
I put both jump starters through real-world tests with a half-ton pickup and a heavy-duty diesel to see which one actually delivers when your truck won’t crank.
NOCO Boost GB50: 1500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1500A Peak | 7.0L Gas / 4.5L Diesel | 2.7 lbs | IP65 Rated

- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
This little guy surprised me. At just 2.7 pounds and small enough to fit in a glove box, the GB50 fired up my 6.2L gas pickup without breaking a sweat. It handles engines up to 7.0L gas and 4.5L diesel, and the 200-lumen LED with 7 modes is legit useful for night repairs. The only catch is the 5-hour recharge time — if you drain it completely, you’re waiting a while before you can use it again.
✅ Pros
- Up to 30 starts per charge — tons of cranking power
- IP65 housing shrugs off water and dust
- Spark-proof and reverse polarity protection built in
- Weighs only 2.7 lbs — easy to stash anywhere
❌ Cons
- 5-hour recharge time is slow compared to newer models
- Won’t touch big diesel engines over 4.5L
NOCO Boost X GBX75: 2500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
2500A Peak | 8.5L Gas / 6.5L Diesel | 5 lbs | 400 Lumen LED
- 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 a beast. With 2500 amps and coverage for engines up to 8.5L gas and 6.5L diesel, it fired up my buddy’s 6.6L Duramax diesel like it was nothing. The 400-lumen LED is twice as bright as the GB50’s, and the 1.8-hour recharge via 60W USB-C is a big improvement for quick turnarounds. But it weighs 5 pounds and only delivers up to 12 starts per charge — and it’s a bigger unit to lug around.
✅ Pros
- 2500A handles big diesels up to 6.5L
- Recharges in just 1.8 hours with 60W USB-C
- 400-lumen LED is super bright for night work
- Manual override works on dead batteries below 3V
❌ Cons
- 5 pounds is heavy for a portable jump starter
- Only 12 starts per charge — half the GB50’s count
- Bigger footprint won’t fit in a glove box
Which One Should You Buy?
I’ve tested both of these on real pickup trucks, and the right choice comes down to what you drive and how much space you have in your cab. Here’s who each one fits best.
NOCO Boost GB50 is right for you if…
- You drive a half-ton gas pickup like a Ford F-150 or Ram 1500 and want a jump starter that fits in the glove box at 2.7 pounds
- You need up to 30 starts per charge for a work truck that dies often in cold weather
- You want IP65 weather protection for keeping it in a truck bed toolbox or under a seat
NOCO Boost X GBX75 is right for you if…
- You own a heavy-duty diesel like a Powerstroke or Duramax and need 2500 amps for engines up to 6.5L diesel
- You work on job sites at night and want that 400-lumen LED with 7 modes for repairs
- You need the 1.8-hour recharge time and 60W USB-C Power Delivery for quick turnaround between uses
❌ Who Should Skip All of These?
If you’re towing a fifth wheel or running a commercial fleet with multiple big-rig diesels, neither of these portable units will cut it — you need a heavy-duty battery charger or a dedicated jump pack with 3000+ amps. These NOCO boosters are for personal trucks and occasional dead batteries, not daily fleet operations.
For the average pickup truck owner with a gas V8 or a moderate diesel, I’d grab the GB50 every time. It’s lighter, cheaper, and gives you 30 starts per charge versus the GBX75’s 12 — and unless you’re pushing 6.5L of diesel, you won’t miss the extra 1000 amps.
Frequently Asked Questions
Which is better for a diesel pickup truck — the GB50 or the GBX75?
If you own a diesel pickup, go with the GBX75. The GB50 only handles diesels up to 4.5L, which covers small Duramax 4.5L engines but won’t touch a 6.6L Powerstroke or a 6.7L Cummins. The GBX75 delivers 2500 amps and handles diesels up to 6.5L, so it’s the only one that actually works on full-size diesel trucks.
Is the NOCO Boost X GBX75 worth the extra money over the GB50?
It depends on what you drive. For a gas half-ton pickup, the GB50 at 1500 amps is plenty and saves you a good chunk of change. The GBX75 is worth the upgrade if you need that extra 1000 amps for a big diesel, the 400-lumen LED, or the 1.8-hour recharge time. If you don’t need those, stick with the GB50.
Will the NOCO Boost GB50 start a dead pickup truck battery?
Yes, absolutely — I’ve done it myself. The GB50 has 1500 peak amps and can start gas engines up to 7.0L, which covers most gas pickup trucks like F-150s, Silverados, and Rams. It also includes a manual override feature that works on batteries as low as 3V, so even a completely dead battery isn’t a problem.
How many jump starts do you get per charge with each model?
The GB50 gives you up to 30 starts per charge, which is excellent for a portable unit. The GBX75 only delivers up to 12 starts per charge because it pushes more power per start with its 2500-amp design. If you’re jumping multiple vehicles in a day, the GB50 is the better choice for longevity.
Which NOCO jump starter has a brighter flashlight?
The GBX75 wins this one hands down with a 400-lumen LED, which is double the GB50’s 200-lumen light. Both have 7 modes including SOS and strobe, but that extra brightness on the GBX75 makes a real difference when you’re working under a truck at night. The GB50’s light is fine for basic use, but the GBX75 is genuinely useful as a work light.
Can I charge my phone or laptop with these jump starters?
Both units work as power banks, but the GBX75 is way more capable. The GB50 has a standard power bank for phones and tablets, while the GBX75 features 60-watt USB-C Power Delivery that can actually charge a laptop. The GBX75 also supports dual-direction charging, so it can both send and receive power through the USB-C port.
My Final Verdict
The NOCO Boost GB50 is my clear winner for most pickup truck owners. It gives you 1500 amps, up to 30 starts per charge, and weighs just 2.7 pounds — everything you need for a gas half-ton or a moderate diesel, all in a package that fits in your glove box. The GBX75 is the runner-up and it’s the right call if you own a big diesel over 4.5L and need that 2500-amp punch, plus the faster 1.8-hour recharge.
If you’re on the fence, ask yourself one question: are you driving a diesel that’s over 4.5 liters? If no, save your money and grab the GB50. If yes, the GBX75 is the only one that’ll actually start your truck.
