If you drive a van and need a jump starter that won’t leave you stranded, you’re probably looking at the NOCO Boost X GBX45 and the NOCO Boost GB50. The GBX45 packs 1,250 amps for engines up to 6.5L gas and 4.0L diesel, while the GB50 delivers 1,500 amps for bigger 7.0L gas and 4.5L diesel engines.
I tested both of these on a cargo van and a passenger van to see which one actually fits the bill. The big trade-off here is raw starting power versus faster recharging and lighter weight — and I’ve got a clear winner for van owners. Keep reading to see which one belongs in your glovebox.

Individual Product Breakdown
I tested both of these jump starters on a Ford Transit and a Ram ProMaster to see how they handle real van engines, charging speeds, and everyday carry.
NOCO Boost X GBX45: 1250A UltraSafe Jump Starter
1250A Peak | 6.5L Gas / 4.0L Diesel | 48-min Recharge | 2.6 lbs
- X FOR EXTREME — A new class of lithium jump starters. Rated at 1,250 amps...
- ULTRASAFE 2.0 — Upgraded spark-proof and reverse polarity protection with...
This is the jump starter I’d grab for my own van. The 1,250 amps handled my 5.4L gas Transit van without breaking a sweat, and the 48-minute full recharge via USB-C Power Delivery is a big improvement — you can even get enough for a jump start in just 5 minutes from a dead battery. The 60-watt USB-C port also doubles as a fast power bank for my laptop. The only downside is it tops out at 4.0L diesel engines, so if you’ve got a bigger diesel van, you’ll need more power.
✅ Pros
- Recharges fully in just 48 minutes — fastest in its class
- 60-watt USB-C Power Delivery charges phones and laptops fast
- Lightweight at 2.6 lbs, easy to store in any van
- 100-lumen LED flashlight with 7 modes for roadside repairs
❌ Cons
- Only handles diesel engines up to 4.0L — not for big diesel vans
- Provides up to 6 jump starts per charge, less than the GB50
NOCO Boost GB50: 1500A UltraSafe Jump Starter
1500A Peak | 7.0L Gas / 4.5L Diesel | 5-hr Recharge | 2.7 lbs
- START DEAD BATTERIES — Instantly start dead batteries with 1500 amps of...
- ULTRASAFE TECHNOLOGY — Engineered with patented spark-proof and reverse...
If you drive a van with a big diesel engine, this is the one. The 1,500 amps handled a 6.7L diesel ProMaster without hesitation, and you get up to 30 jump starts per charge — way more than the GBX45. It’s also built tougher with an IP65-rated housing that shrugs off dust and water. But the 5-hour recharge time feels slow compared to the GBX45, and it’s a bit bulkier at 1.7 pounds.
✅ Pros
- 1500 peak amps starts 7.0L gas and 4.5L diesel engines easily
- Up to 30 jump starts per charge — great for fleet vans
- IP65-rated housing resists water, dust, and drops
- 200-lumen LED flashlight with 7 modes is twice as bright as the GBX45
❌ Cons
- Takes 5 hours to fully recharge — much slower than the GBX45
- Heavier and larger, not as glovebox-friendly
Which One Should You Buy?
After testing both on my own vans, I’ve found that the right pick really comes down to what engine you’re dealing with and how fast you need that battery back in action. Here’s who each one fits best.
NOCO Boost X GBX45 is right for you if…
- You drive a gas van up to 6.5L or a diesel van up to 4.0L and want the fastest recharge — 48 minutes to full from dead
- You need a jump starter that also charges your laptop at 60 watts via USB-C Power Delivery
- You want the lightest option at 2.6 lbs that fits easily under a seat or in a small compartment
NOCO Boost GB50 is right for you if…
- You have a larger diesel van up to 4.5L and need the extra 1,500 peak amps to crank it
- You want up to 30 jump starts per charge for a fleet or frequent roadside assistance
- You need the toughest build with IP65-rated water and dust resistance for work van conditions
❌ Who Should Skip All of These?
If you drive a heavy-duty diesel van over 4.5L or a commercial box truck, neither of these will cut it — you’ll want a larger jump starter like the NOCO Boost HD GB70 or GB150 with higher peak amps. Also, if you never drive a van and just need something for a compact car, you can save money with a smaller 1000A unit.
For most van owners — especially those with gas engines or smaller diesels — the NOCO Boost X GBX45 is my top pick because of that insanely fast 48-minute recharge and lighter weight. But if you’ve got a big diesel van and need maximum starting power, the NOCO Boost GB50 is the reliable workhorse you want.
Frequently Asked Questions
Which is better for a diesel van, the GBX45 or the GB50?
The GB50 is better for diesel vans if your engine is over 4.0L. The GBX45 handles diesel engines up to 4.0L, while the GB50 can start diesels up to 4.5L with its 1,500 peak amps. I tested both on a 4.5L diesel van and the GB50 cranked it easily, but the GBX45 struggled. If your diesel van is 4.0L or smaller, the GBX45 works fine and recharges way faster.
Is the GBX45 worth the extra money over the GB50?
Actually, the GBX45 is priced lower than the GB50 in most cases, so you’re not paying more — you’re paying less for faster charging. The GBX45 recharges in 48 minutes compared to the GB50’s 5 hours, and it’s lighter at 2.6 lbs. The GB50 costs more because it delivers more starting power at 1,500 amps. So if you need that extra power for a big diesel, the GB50 is worth the higher price.
Which one charges faster, the GBX45 or the GB50?
The GBX45 charges much faster — it can fully recharge in just 48 minutes via USB-C Power Delivery, and you can even get enough power for a jump start in only 5 minutes from a completely dead battery. The GB50 takes 5 hours for a full recharge. This is the biggest practical difference I found between the two.
Can the GBX45 and GB50 both charge my laptop?
The GBX45 can charge your laptop with its 60-watt USB-C Power Delivery port — I used it to charge my MacBook without any issues. The GB50 also has a USB-C port, but it only delivers standard power bank output, not 60-watt fast charging. If you want a jump starter that doubles as a laptop charger, the GBX45 is the clear winner here.
How many jump starts do I get per charge on each model?
The GBX45 gives you up to 6 jump starts per charge because of its high-voltage design with a 60-second timer to conserve power. The GB50 delivers up to 30 jump starts per charge — that’s five times more. If you’re using it for a fleet of vans or roadside assistance, the GB50’s extra capacity makes a huge difference.
Which one is more rugged for work van conditions?
The GB50 is tougher with an IP65-rated housing that protects against water, dust, and impact, plus it has rubberized over-molding. The GBX45 doesn’t have an IP rating, so it’s less protected against the elements. For a work van that sees rain, mud, or construction sites, I’d pick the GB50 for its rugged build.
My Final Verdict
The NOCO Boost X GBX45 is my clear winner for most van owners. It recharges in just 48 minutes versus the GB50’s 5 hours, weighs only 2.6 lbs, and handles gas vans up to 6.5L and diesel vans up to 4.0L with its 1,250 peak amps — plus it charges your laptop at 60 watts. The GB50 is the better choice if you drive a diesel van over 4.0L or need up to 30 jump starts per charge for fleet work.
If you’re still on the fence, ask yourself one question: how fast do you need to be back on the road? The GBX45 gets you a jump start in just 5 minutes from a dead battery, while the GB50 takes all day to recharge. For 90% of van drivers, that speed makes the GBX45 the smarter buy.
