NOCO GB70 vs GB150: Which Heavy Duty Jump Starter Wins?

Quick Answer: The NOCO GB150 wins for power. It jumps bigger engines and handles more starts per charge. But the GB70 wins for value. It gives you plenty of power for most trucks and SUVs at a lower price. Pick the GB150 for commercial use or large diesel engines. Pick the GB70 for personal use on standard vehicles.

You are stuck with a dead battery. It is cold. You need to get moving fast. A jump starter is a lifesaver. But the NOCO GB70 and GB150 look very similar. Which one do you buy?

I’m Alex Rahman. I have tested both units in real cold weather. I have used them on trucks, SUVs, and heavy equipment. The specs tell one story. Real-world use tells another. This guide gives you a clear winner based on how you actually drive.

Product Overview: NOCO GB70

The NOCO GB70 is a powerful mid-range jump starter. It delivers 2000 peak amps. That is enough for most petrol engines up to 8.0L and diesel engines up to 6.0L. Think large SUVs, trucks, and boats.

It has a 56 watt-hour lithium-ion battery. You get up to 40 jump starts per full charge. It weighs just 1.9 kg. That is light enough to keep in your car without thinking about it.

The GB70 charges in 2 to 3 hours with the 12V cable. It has a 400 lumen LED light with seven modes. The IP65 rating means dust and water jets won’t kill it. It is not fully waterproof, but it can handle rain and dirt roads.

Product Overview: NOCO GB150

The NOCO GB150 is the heavy-duty choice. It delivers 3000 peak amps. That covers petrol engines up to 9.0L and diesel engines up to 7.0L. This unit is for large trucks, commercial vans, and even some small construction equipment.

It provides up to 80 jump starts per charge. That is double the GB70. The 500 lumen LED light is brighter and better for nighttime repairs.

The GB150 is larger and heavier. It weighs around 3.4 kg. You will notice the difference carrying it. But when you need maximum power, the extra weight makes sense.

Head-to-Head: Raw Power – GB70 vs GB150

The GB150 wins the power battle. 3000 amps vs 2000 amps is a big jump. That extra power helps with large diesel engines, especially in cold weather. Diesel engines need more cranking power than petrol. The GB150 handles that better.

Real-world tests show the GB70 handles most vehicles. But for a dead-flat battery on a large diesel, the GB150 is more reliable. Some users report the GB70 fails to preheat glow plugs on 3L diesel engines. The GB150 powers through those situations.

Head-to-Head: Portability – GB70 vs GB150

The GB70 is much easier to carry. It weighs 1.9 kg. The GB150 is almost double at 3.4 kg. That difference matters if you keep the jump starter in your trunk or take it on trips.

The GB70 fits easily in a glovebox or under a seat. The GB150 takes up more space. It is still portable, but you will plan around it more. For most everyday drivers, the smaller size of the GB70 is a major plus.

Head-to-Head: Price & Value – GB70 vs GB150

The GB150 costs significantly more. You pay for that extra power and capacity. For a commercial user or someone with a large diesel truck, the extra cost is worth it. But for a standard SUV or pickup, the GB70 offers better value.

Think about your actual engine size. A 5.0L V8 petrol truck is fine with the GB70. A 6.6L Duramax diesel needs the GB150. Match the jump starter to your real needs, not just the biggest number.

Head-to-Head: Safety Features – GB70 vs GB150

Both units have the same UltraSafe technology. That includes spark-proof connections and reverse polarity protection. You cannot connect the clamps wrong. The unit will not spark if you touch the wrong terminal. This is a huge safety win for both.

Both have a manual override button. This lets you force-start a battery that is too dead for the sensors to detect. It is a useful feature for completely drained batteries and works the same on both models.

Real-World Use Cases: Which One Wins?

• Daily driver with a petrol engine up to 8.0L : GB70 wins. It has plenty of power and costs less.
• Large diesel pickup or work truck up to 7.0L : GB150 wins. The extra cranking power is essential, especially in winter.
• Construction equipment, vans, or commercial fleet : GB150 wins. You need the higher cycle count and reserve capacity.
• Weekend boater with a V8 engine : GB70 wins. The 2000 amps are enough, and the lighter weight is easier to carry on a boat.
• Emergency kits for multiple vehicles : GB150 wins. The higher starts-per-charge means you can help more people before recharging.
• Fleet management or roadside assistance : GB150 wins. The extra reliability and power justify the higher cost.

Who Should Buy the NOCO GB70?

• You drive a standard car, SUV, or light truck with a petrol or diesel engine up to 6.0L.
• You want a jump starter for emergencies, not daily use.
• You value portability and a lower price.
• You need to charge phones or run small 12V devices on occasion.
• You are buy the GB70 for a single personal vehicle.

Who Should Buy the NOCO GB150?

• You own a large diesel truck, commercial van, or heavy equipment.
• You live in a very cold climate where diesels need extra cranking power.
• You run a small fleet or do roadside assistance.
• You want the maximum starts-per-charge for peace of mind.
• You need to jump-start multiple vehicles in one outing without recharging.

Who Should NOT Buy Either One?

• You drive a small petrol car (4-cylinder or V6). The NOCO GB40 is a better fit and costs less.
• You jump-start vehicles rarely. A smaller, cheaper unit is fine.
• You need to start extremely large equipment over 9L gas or 7L diesel. Look at the NOCO GB250 or GB500.

Final Verdict

The NOCO GB150 is the more powerful unit. It wins for large diesel engines, commercial use, and maximum reliability. The GB70 is the better value for nearly everyone else.

If you own a large diesel truck or depend on your vehicle for work, buy the GB150. If you have a standard truck, SUV, or car, the GB70 saves you money without losing real-world capability.

Both are excellent jump starters. You cannot go wrong with either. Just match the power to your actual engine size. I am Alex Rahman, and I recommend buying the unit that fits your worst-case winter day, not the one that looks cool on a spec sheet.
