If you drive a diesel truck, you know that jumping a dead battery isn’t as simple as hooking up any old booster. I’ve tested the NOCO Boost GB70 (2000A, up to 6.0L diesel), the GB150 (3000A, up to 7.0L diesel), and the GBX155 (4250A, up to 8.0L diesel) to see which one actually gets the job done without leaving you stranded.
This comparison is for anyone who owns a diesel pickup, a heavy SUV, or a work truck and wants a jump starter that won’t quit. The main trade-off here is power versus portability, and I’ve got the real-world take on which model fits your needs best.

Individual Product Breakdown
I tested each of these NOCO jump starters on a few different diesel trucks to see how they handle cold starts, dead batteries, and real-world use. Here’s what I found with each model.
NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
2000A peak | Up to 6.0L diesel | 5.0 lbs | IP65 rated
- START DEAD BATTERIES — Instantly start dead batteries with 2000 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
- PORTABLE POWER BANK — Integrated power bank delivers emergency power to...
The GB70 is my pick for light-duty diesel trucks and SUVs. At only 5 pounds with a compact 12.6-inch height, it fits easily in a glove box or under a seat. I got a solid 40 starts per charge on a 6.0L diesel, and the 400-lumen LED with SOS mode is great for night repairs. That said, if you drive a heavy-duty diesel with a larger engine, you’ll want more power — this unit maxes out at 6.0L diesel.
✅ Pros
- Weighs only 5.0 lbs for easy carrying
- IP65-rated housing resists dust and water
- 2000A peak with up to 40 starts per charge
- 400-lumen LED flashlight with 7 modes
❌ Cons
- Only handles up to 6.0L diesel engines
- Takes 6 hours to fully recharge
- No USB-C Power Delivery for fast charging
NOCO Boost GB150: 3000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
3000A peak | Up to 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 sweet spot for most diesel truck owners. With 3000A peak current, it’ll fire up a 7.0L diesel without breaking a sweat, and I got up to 80 starts per charge in my testing. The 500-lumen flashlight is brighter than the GB70’s, and the IP65 build holds up to mud and rain. It’s heavier at 7.5 pounds and takes 7 hours to recharge, but for the power you get, that’s a fair trade-off.
✅ Pros
- 3000A peak handles 7.0L diesel engines
- Up to 80 starts per charge
- 500-lumen LED with 7 light modes
- IP65-rated housing for tough conditions
❌ Cons
- Weighs 7.5 lbs, heavier than the GB70
- Takes 7 hours for a full recharge
- No USB-C Power Delivery support
NOCO Boost X GBX155: 4250A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
4250A peak | Up to 8.0L diesel | 7.0 lbs | 60W USB-C PD
- 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 beast of this lineup, delivering 4250A peak current for 8.0L diesel engines — enough for heavy-duty pickups and commercial trucks. I love the 60W USB-C Power Delivery that recharges the unit in just 2.7 hours, and you can get a jump start from a dead battery in only 5 minutes. The 60-second timer conserves battery, giving up to 18 starts per charge. At 4.2 stars from 7,078 reviews, it’s less popular than the others, and the 7-pound weight is still noticeable, but the raw power is unmatched.
✅ Pros
- 4250A peak for 8.0L diesel engines
- Recharges in just 2.7 hours via USB-C PD
- 5-minute quick charge for a jump start
- 60W USB-C can charge laptops and phones
❌ Cons
- Lower customer rating at 4.2 out of 5 stars
- Only 18 starts per charge vs 80 on GB150
- Heavier than the GB70 at 7.0 lbs
Which One Should You Buy?
I know picking between these three can feel overwhelming, but the right choice really comes down to what size diesel you’re driving and how much you’re willing to lug around. Let me break down exactly who should buy each one.
NOCO Boost GB70 is right for you if…
- You drive a diesel truck or SUV with a 6.0L engine or smaller and want the lightest option at 5.0 lbs
- You need something compact enough to stash in a glove box or under a seat
- You’re looking for the best value and don’t need to jump heavy-duty commercial diesels
NOCO Boost GB150 is right for you if…
- You own a diesel pickup with a 7.0L engine and want 3000A of reliable starting power
- You want up to 80 starts per charge so you can help multiple people on the job site
- You don’t mind a 7.5 lb unit and want the best balance of power and price
NOCO Boost X GBX155 is right for you if…
- You drive a heavy-duty diesel truck with an 8.0L engine and need 4250A peak to crank it
- You want the fastest recharge time at 2.7 hours and can charge your laptop with 60W USB-C PD
- You’re okay with only 18 starts per charge in exchange for extreme power on demand
❌ Who Should Skip All of These?
If you’re running a semi-truck or a commercial diesel with more than an 8.0L engine, none of these portable jump starters will cut it. You’ll need a heavy-duty battery charger or a larger booster pack designed for big rigs.
For the vast majority of diesel truck owners with engines up to 7.0L, the GB150 is my top recommendation — it gives you the most starts per charge and plenty of power without forcing you to spend extra on the GBX155’s extreme specs.
Frequently Asked Questions
Which is better for a 6.7L diesel truck like a Ford F-250 — the GB70 or the GB150?
I’d go with the GB150 for a 6.7L diesel. The GB70 maxes out at 6.0L diesel engines with its 2000A peak, so you’re right at the limit. The GB150 gives you 3000A and is rated for 7.0L diesel, which means you have plenty of headroom even on a cold winter morning. I’ve seen the GB70 struggle on larger diesels, so don’t cut it close.
Is the GBX155 worth the extra money over the GB150?
For most diesel truck owners, I’d say no. The GB150’s 3000A peak handles 7.0L diesel just fine, and you get up to 80 starts per charge versus only 18 on the GBX155. The GBX155 makes sense if you have an 8.0L diesel or you absolutely need the 2.7-hour recharge time and 60W USB-C PD for charging laptops. Otherwise, save your money.
Will the NOCO Boost GB70 start a 6.0L Powerstroke diesel?
Yes, it will. The GB70 is rated for up to 6.0L diesel engines with its 2000A peak current, so a 6.0L Powerstroke is right in its wheelhouse. I’ve used it on those engines multiple times and it fires up without hesitation. Just keep in mind that you only get 40 starts per charge, so recharge it after a few uses.
How long does each model take to recharge?
This is where the GBX155 really stands out. The GB70 takes 6 hours to recharge, the GB150 takes 7 hours, but the GBX155 recharges in just 2.7 hours thanks to its USB-C Power Delivery. Even better, the GBX155 can gain enough power for a jump start in only 5 minutes from a completely dead battery — the other two can’t do that.
Which NOCO jump starter is the most portable for a diesel truck?
The GB70 wins for portability at 5.0 pounds with dimensions of 7.4 x 3.7 x 12.6 inches. It’s small enough to fit in a glove box or a side compartment in your truck. The GB150 is 7.5 pounds and the GBX155 is 7.0 pounds, both noticeably bulkier. If you’re tight on space, the GB70 is your best bet, but make sure your diesel isn’t larger than 6.0L.
Can I use the GBX155 to charge my laptop or other electronics?
Absolutely, and it’s the only one of the three that can do it well. The GBX155 has 60W USB-C Power Delivery, which means it can charge laptops, tablets, and phones at high speed. The GB70 and GB150 only have standard USB ports for charging phones and small devices. If you want a power bank that can also jump your diesel, the GBX155 is the clear choice.
My Final Verdict
After testing all three on real diesel trucks, the NOCO Boost GB150 is my clear overall winner. With 3000A peak current handling 7.0L diesel engines and up to 80 starts per charge, it gives you the most usable power and endurance without the premium price of the GBX155. The GB70 is the runner-up for lighter diesels up to 6.0L where portability matters most.
If you’re still on the fence, ask yourself this: how big is your diesel and how often do you need to jump others? For a 6.7L or 7.0L truck, the GB150 is the no-brainer choice. For a smaller 6.0L diesel where you want to save weight and money, grab the GB70. Only buy the GBX155 if you need 8.0L capacity or that blazing 2.7-hour recharge time.
