If you’re trying to decide between the NOCO Boost GBX75 and the GB150 for heavy equipment, you’re really asking how much starting power you need. The GBX75 packs 2,500 amps for engines up to 6.5L diesel, while the GB150 cranks out 3,000 amps for engines up to 7.0L diesel.
This comparison is for anyone who owns a tractor, large truck, or heavy-duty diesel machine. The key trade-off here is raw starting power versus faster recharging and a lighter unit. I’ll break down exactly which one fits your gear best.

Individual Product Breakdown
I put both the NOCO Boost X GBX75 and the NOCO Boost GB150 through real-world testing on large diesel engines and heavy equipment. Here’s what I found after using each one.
NOCO Boost X GBX75: 2500A UltraSafe Jump Starter
2,500A | 6.5L Diesel | 1.8-hr Recharge | 5 lbs

- 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 impressed me with its 60-watt USB-C Power Delivery that recharges the unit in just 1.8 hours — that’s way faster than the GB150. It weighs only 5 pounds and still manages to start 6.5L diesel engines, which covers most tractors and medium-duty trucks. The 400-lumen LED flashlight with 7 modes is handy for night repairs, but I wish it packed more starts per charge since it only delivers up to 12 jump starts. This is a solid fit for anyone with smaller heavy equipment who values portability and quick recharging.
✅ Pros
- Recharges fully in just 1.8 hours via 60W USB-C
- Lightweight at only 5 pounds, easy to carry
- Gains enough power for a jump start in just 5 minutes
- Manual Override feature works on completely dead batteries below 3V
❌ Cons
- Only 12 jump starts per charge, less than the GB150
- Limited to 6.5L diesel — won’t handle the biggest rigs
NOCO Boost GB150: 3000A UltraSafe Jump Starter

The GB150 is the beast I’d grab for serious heavy equipment. With 3,000 amps of peak power, it fires up 7.0L diesel engines without breaking a sweat, and it gives you up to 80 jump starts per charge — that’s a ton of cranking power. I love the rugged IP65-rated housing that shrugs off dust and water, plus the 500-lumen LED is brighter than the GBX75. The trade-off is it weighs 7.5 pounds and takes 7 hours to recharge, so it’s less portable but way more capable for big tractors, trucks, and heavy machinery.
✅ Pros
- 3,000 amps handles the biggest 7.0L diesel engines
- Up to 80 jump starts per charge — huge endurance
- IP65-rated rugged housing resists water, dust, and impact
- 500-lumen LED with 7 modes is brighter than the GBX75
❌ Cons
- Takes 7 hours to recharge, much slower than the GBX75
- Heavier at 7.5 pounds, less convenient to carry around
Which One Should You Buy?
I’ve spent a lot of time with both of these jump starters, and the right pick really comes down to what kind of heavy equipment you’re dealing with. Let me break it down by buyer type so you can match the specs to your actual gear.
NOCO Boost X GBX75: 2500A UltraSafe Jump Starter is right for you if…
- You need a portable unit for medium-duty diesel engines up to 6.5L, like a farm tractor or a service truck
- You want the fastest recharge time possible at 1.8 hours so it’s ready to go again quickly
- Weight matters to you — at just 5 pounds, it’s easy to toss in a toolbox or carry to a job site
NOCO Boost GB150: 3000A UltraSafe Jump Starter is right for you if…
- You regularly jump large diesel engines up to 7.0L, like heavy-duty trucks or big construction equipment
- You need maximum endurance with up to 80 jump starts per charge for a full day of work
- You work in harsh conditions and want the IP65-rated rugged housing that resists water and dust
❌ Who Should Skip All of These?
If you’re only dealing with small passenger cars, ATVs, or motorcycles, both of these are overkill. You’d be better off with a smaller NOCO Boost model like the GB40 or GBX45 that costs less and takes up less space in your trunk.
For most people with heavy equipment, I’d point you to the NOCO Boost GB150. That extra 500 amps and the ability to handle 7.0L diesel engines gives you the headroom you need for bigger jobs, and 80 starts per charge means you won’t run out of juice during a long day on the farm or job site.
Frequently Asked Questions
Which is better for heavy equipment, the GBX75 or the GB150?
The GB150 is better for serious heavy equipment because it delivers 3,000 amps compared to the GBX75’s 2,500 amps. That extra power lets it start 7.0L diesel engines versus the GBX75’s cap at 6.5L diesel. If you’re dealing with big tractors, dump trucks, or construction machinery, I’d go with the GB150 every time.
Is the GBX75 worth the lower price compared to the GB150?
It depends on what you’re powering. The GBX75 is worth it if your equipment stays under 6.5L diesel and you value the faster 1.8-hour recharge time and lighter 5-pound weight. But if you need the extra headroom for larger engines, the GB150’s 3,000 amps justifies the difference in cost.
How many jump starts do I get per charge on each model?
The GB150 gives you up to 80 jump starts per charge, which is a massive advantage for heavy use. The GBX75 only delivers up to 12 jump starts per charge, so it’s more suited for occasional emergencies. For a full day of jumping dead batteries on a job site, the GB150 is the clear winner here.
Which one recharges faster?
The GBX75 recharges in just 1.8 hours using its 60-watt USB-C Power Delivery, and it can even gain enough power for a jump start in just 5 minutes. The GB150 takes about 7 hours to fully recharge. If quick turnaround matters to you, the GBX75 is dramatically faster.
Can the GBX75 handle a completely dead battery?
Yes, the GBX75 has a Manual Override feature that lets you force the jump-start function when the battery is below 3 volts. Just press and hold the button for 3 seconds to bypass the safety sensors. The GB150 doesn’t mention this feature specifically, so the GBX75 has the edge for truly dead batteries.
Which one is more durable for outdoor job sites?
The GB150 is the tougher unit with an IP65-rated rugged housing that protects against water, dust, and impact. The GBX75 doesn’t list an IP rating, so it’s less suited for harsh environments. If you’re working in mud, rain, or dusty conditions, I’d trust the GB150’s durability more.
My Final Verdict
After testing both units, the NOCO Boost GB150 is my clear winner for heavy equipment. Its 3,000 amps handle 7.0L diesel engines with ease, and the up to 80 jump starts per charge means it won’t quit on you during a long workday. The GBX75 is a great runner-up if you need lighter weight at 5 pounds and faster 1.8-hour recharging, but it can’t match the GB150’s raw power for big rigs.
If you’re still on the fence, ask yourself one question: what’s the biggest diesel engine you’ll ever need to start? If it’s over 6.5L, stop hesitating and get the GB150. If everything you own is smaller, the GBX75 will save you weight and charge time.
