While the NOCO GB40 is the perfect solution for most daily drivers, what if you're not most drivers? What if you have a heavy-duty truck, a large V8 engine, an RV, or you're a professional who needs to start multiple dead vehicles?
That's when you step up to the professional-grade powerhouse: the NOCO Boost GB70 2000A UltraSafe Jump Starter.
This is the model designed for heavy-duty work and maximum power. We're breaking down what that extra 1000 Amps gets you and who this model is truly built for.
1. The Power: What 2000A Can Really Do
The 1000A from the GB40 is impressive, but the 2000A from the GB70 is in another league. This power rating allows it to start much larger and more demanding engines:
- Gasoline Engines: Up to 8.0 Liters
- Diesel Engines: Up to 6.0 Liters
What this means in the real world: This isn't just for your sedan or SUV. The GB70 is built to handle heavy-duty pickup trucks (like a Ford F-250/F-350, Ram 2500, or Chevy Silverado HD), large RVs, commercial vans, and boats. It has the raw power to turn over these massive engines, even in cold weather.
2. The "UltraSafe" Technology (Pro-Grade)
Just like its smaller sibling, the GB70 features the same foolproof "UltraSafe" technology. This is critical when dealing with this much power.
- Spark-Proof Technology: Prevents any dangerous sparks.
- Reverse Polarity Protection: Makes it impossible to damage your battery (or the unit) by connecting the clamps backward.
It's the same simple, safe user experience, just backed by twice the power.
3. Key Features the GB70 Has (That the GB40 Doesn't)
The extra price doesn't just get you more power; it gets you upgraded features:
- 12V Power Port: This is a massive upgrade. The GB70 has a 12V output port (15A max) that allows it to power 12V devices directly, such as a tire inflator, a car vacuum, or a portable cooler. The GB40 cannot do this.
- Faster Recharging: The GB70 recharges significantly faster than the GB40 when it's empty.
- Brighter Flashlight: Features a much brighter 400-lumen flashlight (compared to the GB40's 100-lumen light), making it far more useful in an emergency.
Final Verdict: Who Needs the GB70?
While the GB40 is the sensible choice for daily commuting, the NOCO Boost GB70 is the right tool for more demanding users.
This is the model you should buy if:
- You own a heavy-duty truck with a large gas V8 or a diesel engine.
- You own an RV or a boat.
- You are a professional mechanic, tow truck operator, or work on a farm/job site.
- You want the 12V output port to power other accessories like tire inflators.
- You simply want the best "peace of mind" and are willing to pay for the extra power, "just in case."
It’s a complete roadside emergency and portable power solution built for the toughest jobs.
When you need professional-grade power, accept no substitutes.
The NOCO Boost GB70 provides 2000A of "UltraSafe" power for the biggest engines and the ability to power your 12V accessories. This is the ultimate roadside tool.
