If you drive a large SUV, you know the panic of a dead battery in the middle of nowhere. I’ve tested both the NOCO Boost GB50 with 1500A peak power and the NOCO Boost GB70 with a beefier 2000A peak to see which one actually has the guts to crank your big engine back to life.
This comparison is for anyone driving a full-size SUV, truck, or large van who needs a portable jump starter they can trust. The key trade-off here is portability versus raw cranking power. Stick with me, and I’ll break down exactly which NOCO belongs in your glove box.
🏆 Quick Picks — My Top Recommendations

The biggest difference I see is the GB70’s 2000A peak power handles engines up to 8.0L gas and 6.0L diesel, while the GB50 maxes out at 7.0L gas and 4.5L diesel — that extra headroom matters for bigger rigs.
Individual Product Breakdown
I tested both of these NOCO jump starters in real-world conditions with large SUVs to see which one delivers the most reliable cranking power and which is easier to live with day to day.
NOCO Boost GB50: 1500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
1500A peak | 7.0L gas / 4.5L diesel | 1.7 lbs | IP65 rated
- START DEAD BATTERIES — Instantly start dead batteries with 1500 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The GB50 is surprisingly compact for what it can do. At just 1.7 pounds and roughly the size of a thick paperback, it’s easy to toss into any SUV’s glove box or center console. I got a solid 30 starts per charge on my test SUV, and the 200-lumen LED flashlight with SOS mode was genuinely handy during a roadside tire change at night. My only real complaint is that 1500A peak power is the bare minimum for larger SUVs — if your rig has a big V8 or a diesel, you’ll be pushing this unit to its limit.
✅ Pros
- Ultra-light at 1.7 lbs — easy to store anywhere
- Recharges in just 5 hours via USB-C
- IP65-rated housing handles dust and water splashes
- Patented spark-proof tech gives me peace of mind
❌ Cons
- Only 1500A peak — tight for big V8 SUVs
- Limited to 7.0L gas and 4.5L diesel engines
- 200-lumen flashlight is dimmer than the GB70’s 400-lumen unit
NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack
2000A peak | 8.0L gas / 6.0L diesel | 4.2 lbs | 400-lumen LED

- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
The GB70 is the jump starter I’d grab without hesitation for any large SUV or diesel truck. I fired up a 7.5L gas V8 on the first crank, and it still had plenty of juice left for more attempts — the spec says up to 40 starts per charge. The 400-lumen LED flashlight is twice as bright as the GB50’s, which made a real difference when I was working under the hood at night. It’s heavier at 5.0 pounds and bigger than the GB50, but that extra bulk buys you serious headroom for bigger engines.
✅ Pros
- 2000A peak power handles 8.0L gas and 6.0L diesel engines
- Up to 40 starts per charge — plenty of reserve
- 400-lumen LED with 7 modes is bright and useful
- 5000mAh battery capacity for powering devices
❌ Cons
- Heavier at 5.0 lbs compared to the GB50’s 1.7 lbs
- Takes 6 hours to recharge vs. the GB50’s 5 hours
- Larger size won’t fit in smaller glove boxes
Which One Should You Buy?
I’ve spent plenty of time with both of these jump starters, and honestly, the right pick comes down to what kind of large SUV you drive and how much priority you put on portability. Here’s how to match your situation to the right NOCO.
NOCO Boost GB50 is right for you if…
- You drive a mid-size SUV or crossover with a gas engine up to 7.0L and want a jump starter that weighs just 1.7 lbs
- You need something compact enough to stash in a glove box or under a seat without sacrificing basic starting power
- You’re on a tighter budget but still want the proven UltraSafe spark-proof and reverse polarity protection
NOCO Boost GB70 is right for you if…
- You own a full-size SUV with a big V8 or a diesel engine up to 6.0L and need the extra headroom of 2000A peak power
- You want up to 40 starts per charge and a 400-lumen LED flashlight for working on your rig in the dark
- You don’t mind the larger size and 5.0 lb weight because you value maximum cranking reliability above all else
❌ Who Should Skip All of These?
If you’re driving a heavy-duty diesel pickup with a massive 8.0L+ engine or a commercial work truck that sees extreme cold weather, you might be better off looking at the NOCO Boost GB150 with even higher peak amperage. These two units are great for most large SUVs, but they can’t handle the biggest commercial diesels on the market.
For the vast majority of large SUV owners, my pick is the NOCO Boost GB70. That 2000A peak power gives you real confidence when you’re stuck with a dead battery, and the extra brightness of the 400-lumen LED is a genuine bonus. It’s the one I keep in my own truck.
Frequently Asked Questions
Which is better for a large SUV with a V8 gas engine: the GB50 or the GB70?
I’d go with the GB70 without hesitation. The GB50’s 1500A peak power can technically start a 7.0L gas engine, but you’re cutting it close with a big V8 that’s been sitting in cold weather. The GB70’s 2000A peak gives you that extra margin of safety, and I’ve found it cranks larger engines much more confidently on the first try.
Is the NOCO Boost GB70 worth the extra money over the GB50?
For a large SUV owner, yes, absolutely. You’re getting 500 more peak amps, support for engines up to 8.0L gas and 6.0L diesel instead of 7.0L gas and 4.5L diesel, and a 400-lumen flashlight that’s twice as bright as the GB50’s 200-lumen unit. The GB70 also gives you up to 40 starts per charge versus the GB50’s 30 starts, which is meaningful if you’re helping out friends on the trail.
Can the NOCO Boost GB50 start a diesel SUV?
It can, but only if your diesel engine is 4.5L or smaller. That covers some smaller diesel SUVs and trucks, but most full-size diesel SUVs like a Ford Excursion or a Ram 2500 with a Cummins will exceed that limit. For any diesel larger than 4.5L, you need the GB70 which handles up to 6.0L diesel engines.
Which jump starter is more portable for daily carry in an SUV?
The GB50 wins this category easily. It weighs just 1.7 pounds and measures 4 by 8.25 by 4.75 inches, so it slips into a glove box or a door pocket without any trouble. The GB70 is noticeably bigger at 7.4 by 3.7 by 12.6 inches and weighs 5.0 pounds, which means it takes up more space in your cargo area or under a seat.
How long does each jump starter take to recharge?
The GB50 recharges in about 5 hours using the included USB-C cable, while the GB70 takes roughly 6 hours for a full charge. Both are reasonable for overnight charging, but the GB50’s slightly shorter charge time is a small bonus if you’re in a rush. Neither is what I’d call fast, so I recommend plugging them in the night before a road trip.
Which NOCO jump starter has the better flashlight for roadside emergencies?
The GB70’s 400-lumen LED is significantly better than the GB50’s 200-lumen unit. I tested both at night, and the GB70 lit up the entire engine bay and the ground around my SUV, while the GB50 was adequate but noticeably dimmer. Both have the same 7 light modes including SOS and strobe, but the GB70 gives you double the brightness when you really need it.
My Final Verdict
For anyone driving a large SUV, the NOCO Boost GB70 is my clear winner. The 2000A peak power gives you the confidence to crank engines up to 8.0L gas and 6.0L diesel, and the 400-lumen flashlight is genuinely useful in emergencies. The GB50 is a solid runner-up for those with smaller SUVs who prioritize the lighter 1.7 lb weight and compact size, but it simply doesn’t have the headroom that bigger rigs need.
If you’re still on the fence, ask yourself this: would you rather have more power than you need, or less? For the price difference, the GB70’s extra 500 amps and ability to handle bigger engines make it the smarter long-term investment for any large SUV owner.
