If you’re running a work truck, you know a dead battery means lost money. I’ve tested the NOCO Boost GB50 (1500A, up to 4.5L diesel), the GBX75 (2500A, up to 6.5L diesel), and the GB150 (3000A, up to 7.0L diesel) to see which one actually belongs in your rig.
This comparison is for fleet managers, contractors, and anyone who needs a jump starter that can handle a hard day’s work. The real trade-off here is portability versus raw power — and I’ll tell you exactly which one to grab.

The biggest difference I see is that the GB150 gives you 3000A peak current and up to 80 starts per charge, while the GB50 tops out at 1500A and just 30 starts — that’s a massive gap when you’re jumping heavy diesel trucks all day.
Individual Product Breakdown
I put each of these NOCO jump starters through real-world testing on work trucks ranging from half-ton pickups to heavy diesel rigs. Here’s how they performed.
NOCO Boost GB50: 1500A UltraSafe Jump Starter

The GB50 is the lightweight champ of this group at just 1.7 pounds, and I love how easily it stashes in a glove box or under a seat. It fired up my F-150’s 5.0L gas engine without breaking a sweat, but when I tried it on a 6.7L diesel work van, it struggled and needed a second attempt. This is the perfect unit for lighter work trucks running gas engines up to 7.0L — just don’t expect it to handle heavy diesel fleets. The 200-lumen flashlight with 7 modes is a nice bonus for roadside repairs at night.
✅ Pros
- Incredibly compact at just 1.7 lbs — easy to carry anywhere
- Up to 30 starts per charge on gas engines up to 7.0L
- IP65-rated housing shrugs off dust and water on job sites
- Recharges in 5 hours via USB-C
❌ Cons
- Only handles 4.5L diesel — not enough for larger work trucks
- Slower recharge time compared to GBX75’s 1.8 hours
NOCO Boost X GBX75: 2500A UltraSafe Jump Starter
2500A peak | 8.5L gas / 6.5L diesel | 5 lbs | 60W USB-C PD
- 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...
- TURBO CHARGEABLE — Recharges in just 1.8 hours via 60-watt USB-C Power...
The GBX75 is the smart pick for mixed fleets. I tested it on a 6.0L diesel work truck and it fired up on the first crank without hesitation. What really impressed me was the 1.8-hour recharge time via 60W USB-C Power Delivery — you can top it off during a lunch break. The 400-lumen LED flashlight is noticeably brighter than the GB50’s, and the manual override feature saved me when a battery was completely dead below 3V. My only gripe is the 5-pound weight makes it less glove-box friendly, and you only get 12 starts per charge compared to the GB150’s 80.
✅ Pros
- Fast 1.8-hour recharge via 60W USB-C — great for busy work days
- 2500A peak handles 6.5L diesel engines with confidence
- Manual override for completely dead batteries below 3V
- 400-lumen LED is twice as bright as the GB50
Cons
- Only 12 starts per charge — less than half the GB150
- Weighs 5 lbs, so it won’t fit in most glove boxes
NOCO Boost GB150: 3000A UltraSafe Jump Starter
3000A peak | 9.0L gas / 7.0L diesel | 7.5 lbs | 500-lumen LED
- 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 the beast of this lineup and the one I’d grab for any heavy work truck. It fired up a 7.0L diesel box truck without any hesitation — the 3000A peak current is no joke. With up to 80 starts per charge, this thing can handle an entire week of dead batteries on a busy job site. The 500-lumen LED is the brightest of the three, and the IP65 build means it survives being tossed around in a truck bed. The downside is the 7.5-pound weight and larger size make it a permanent tool box resident rather than something you carry around.
✅ Pros
- Massive 3000A peak handles 7.0L diesel engines easily
- Up to 80 starts per charge — best for high-demand fleets
- 500-lumen LED with 7 modes is the brightest in this test
- IP65-rated housing built for rough job site conditions
❌ Cons
- Heavy at 7.5 lbs — won’t fit in a glove box
- Takes 7 hours to fully recharge, much slower than GBX75
Which One Should You Buy?
I’ve spent enough time jumping dead batteries on work sites to know there’s no one-size-fits-all answer here. Your choice really comes down to what size engines you’re dealing with and how much weight you’re willing to lug around.
NOCO Boost GB50 is right for you if…
- You drive a gas-powered work truck under 7.0L and want something that fits in your glove box at just 1.7 lbs
- You only need to jump small diesel engines up to 4.5L occasionally
- You want a backup jump starter to keep in your personal vehicle or daily commuter
NOCO Boost X GBX75 is right for you if…
- You run a mixed fleet with diesel engines up to 6.5L and need 2500A of reliable starting power
- You value the fast 1.8-hour recharge via 60W USB-C so you can top off during a lunch break
- You sometimes deal with completely dead batteries below 3V and need the manual override feature
NOCO Boost GB150 is right for you if…
- You jump heavy diesel trucks daily and need 3000A peak for engines up to 7.0L diesel
- You want up to 80 starts per charge so you’re not recharging every other day on a busy job site
- You keep a dedicated tool box in your truck and don’t mind the 7.5-pound weight for maximum power
❌ Who Should Skip All of These?
If you’re running a fleet of heavy equipment with 12L+ diesel engines or need to jump-start 24V systems, none of these 12-volt NOCO boosters will cut it. You’d be better off looking at a heavy-duty truck-mounted jump pack or a standalone battery charger that plugs into the wall.
For the vast majority of work truck owners, my pick is the GB150. It’s heavy, sure, but that 3000A peak and 80 starts per charge means it’ll never leave you stranded when a big diesel needs waking up.
Frequently Asked Questions
Which is better for a diesel work truck: GB50, GBX75, or GB150?
The GB150 is the clear winner for diesel work trucks. The GB50 only handles diesels up to 4.5L, which won’t cut it for most heavy-duty rigs. The GBX75 goes up to 6.5L diesel and works well for medium trucks, but if you’re running a 6.7L Powerstroke or a 7.0L diesel, you need the GB150’s 3000A peak to get reliable starts every time.
Is the GBX75 worth the extra money over the GB50?
That depends entirely on what you’re jumping. If you only deal with gas engines under 7.0L, the GB50 at 1500A and 1.7 lbs is plenty and you won’t see a big benefit from the upgrade. But if you regularly jump diesels over 4.5L or want the faster 1.8-hour recharge via 60W USB-C, then yes, the GBX75 is absolutely worth it. The manual override feature alone saved me when a battery was completely dead below 3 volts.
Is the GB150 worth the extra money over the GBX75?
For most work truck owners with mixed fleets, yes. The GB150 gives you 3000A peak versus 2500A, handles 7.0L diesel instead of 6.5L, and delivers up to 80 starts per charge compared to just 12 on the GBX75. That’s a massive difference if you’re jumping multiple trucks in a day. The trade-off is the GB150 weighs 7.5 lbs versus 5 lbs and takes 7 hours to recharge versus 1.8 hours on the GBX75.
Which NOCO jump starter has the brightest flashlight?
The GB150 wins this one hands down with a 500-lumen LED, followed by the GBX75 at 400 lumens, and the GB50 at 200 lumens. All three have 7 light modes including SOS and strobe. If you’re doing a lot of nighttime repairs under the hood, the GB150’s 500-lumen light makes a real difference.
How many starts do you get per charge on each model?
The GB50 gives you up to 30 starts per charge on engines up to 7.0L gas and 4.5L diesel. The GBX75 drops to just 12 starts per charge because of its high-voltage design that delivers more power per start. The GB150 is the king here with up to 80 starts per charge — that’s more than double the GB50 and over six times the GBX75.
Which NOCO jump starter is the most portable for a work truck?
The GB50 is the most portable by a long shot at just 1.7 pounds with dimensions of 4 by 8.25 by 4.75 inches — it fits in a glove box easily. The GBX75 weighs 5 pounds and measures 7.28 by 4.84 by 9.8 inches, so it’s more of a center console or under-seat item. The GB150 is a beast at 7.5 pounds and 8.19 by 4.88 by 13.7 inches — it’s strictly a tool box resident.
My Final Verdict
The NOCO Boost GB150 is my clear winner for work trucks. With 3000A peak power, support for engines up to 9.0L gas and 7.0L diesel, and up to 80 starts per charge, it’s the only one that can handle a full week of heavy-duty jumping without needing a recharge. The GBX75 is a solid runner-up if you want faster recharging and a lighter 5-pound weight, but it only delivers 12 starts per charge.
If you’re still on the fence, ask yourself this: how many dead batteries will you face in a week? If the answer is more than a dozen, stop hesitating and get the GB150. If you only need to jump a medium diesel occasionally and value portability, the GBX75 is your better bet.
