The Ultimate Buyer’s Guide: How to Choose The Right Product for You
Key Factors to Consider
- Peak Amps & Engine Size: This is the most critical factor for diesel trucks. Diesel engines have much higher compression ratios than gasoline engines and require significantly more power to turn over. Look for a jump starter with at least 1500-2000 peak amps for most diesel pickups. For larger engines (over 6.0L) or commercial trucks, consider 3000 amps or more.
- Battery Type (Lithium-ion vs. Lead-Acid): Modern lithium-ion jump starters (like most on our list) are compact, lightweight, and hold a charge for months. Traditional lead-acid jump boxes (like the Clore JNC660) are heavy and bulky but often provide superior, sustained cranking power and are incredibly durable.
- Safety Features: Look for models with spark-proof technology and reverse polarity protection. These features prevent dangerous sparks and protect your vehicle’s electronics if you accidentally connect the clamps incorrectly. A “boost” or “override” button is also essential for starting completely dead batteries.
- Build Quality & Durability: A jump starter is an emergency tool that will likely live in your truck. Look for rugged, rubberized housings and an IP rating (like IP65) which indicates resistance to dust and water. High-quality clamps and thick-gauge cables are also signs of a durable unit.
- Additional Features: Many jump starters double as power banks with USB ports to charge phones and tablets. Some even offer high-wattage USB-C PD ports for charging laptops. A built-in LED flashlight is another common and highly useful feature for roadside emergencies.
Understanding Peak Amps vs. Cranking Amps
When shopping for a jump starter, you’ll see two key power ratings: Peak Amps (PA) and Cranking Amps (CA) or Cold Cranking Amps (CCA). It’s crucial to understand the difference. Peak Amps refers to the maximum burst of power the unit can discharge for a fraction of a second. It’s a useful marketing number, but not the whole story. Cranking Amps (CA), and especially Cold Cranking Amps (CCA), are more important. CCA measures the ability of the unit to deliver a sustained current for 30 seconds at 0°F (-18°C). Diesel engines are notoriously hard to start in the cold due to thickened oil and the power draw from glow plugs. A high CCA rating ensures the jump starter has the endurance to crank the engine long enough to start in frigid conditions.
Common Mistakes to Avoid
- Buying an Underpowered Unit: The most common mistake is buying a jump starter designed for a 4-cylinder car and expecting it to start a 6.7L Cummins. Always check the manufacturer’s recommended diesel engine displacement and err on the side of more power.
- Forgetting to Recharge It: A jump starter is useless if it’s dead. While lithium units hold a charge for a long time, it’s good practice to check and top it off every 3-6 months.
- Storing It in Extreme Temperatures: Lithium-ion batteries can be damaged by prolonged exposure to extreme heat or cold. Try to store your jump starter in the cab of your truck rather than a toolbox in the bed during summer or winter months.
Frequently Asked Questions
How many amps are needed to jump start a diesel engine?
For most light to medium-duty diesel trucks (up to 6.6L), a jump starter with at least 1,500 to 2,000 peak amps is recommended. For larger commercial trucks, heavy-duty pickups, or for reliable starting in very cold climates, look for units with 3,000 peak amps or more.
Are lithium jump starters powerful enough for diesel trucks?
Absolutely. Modern lithium-ion technology has advanced significantly. High-quality lithium jump starters can deliver massive bursts of power, making them more than capable of starting large diesel engines while being a fraction of the size and weight of traditional lead-acid jump boxes.
What are Cold Cranking Amps (CCA) and why are they critical for diesels?
Cold Cranking Amps (CCA) measure a battery’s ability to start an engine at 0°F (-18°C). This is especially critical for diesel engines because their oil thickens more in the cold, and they rely on glow plugs to heat the cylinders, both of which require immense power. A jump starter with a strong CCA rating has the sustained power needed to overcome these challenges.
Can I use a regular car jump starter on my diesel truck?
It is not recommended. A standard jump starter designed for a 4 or 6-cylinder gasoline car typically lacks the necessary amperage to turn over the high-compression engine of a diesel truck. Attempting to do so will likely fail and could potentially damage the jump starter.
What’s the main difference between a gas and a diesel jump starter?
The primary difference is power output. Diesel jump starters are engineered to deliver significantly higher peak and cranking amps to handle the greater demands of diesel engines. They often feature heavier-duty cables and clamps to manage the increased electrical load safely.
How do glow plugs affect jump starting a diesel in the cold?
Glow plugs are heating elements inside each cylinder that are essential for a cold start. They must heat the combustion chamber before you even begin cranking the engine, which can draw a significant amount of power from the battery for several seconds. This initial power draw means your jump starter must have enough reserve capacity to both run the glow plugs and then provide the massive power needed to crank the engine.
What is a ‘manual override’ or ‘boost’ button for on a diesel jump starter?
This is a critical feature. For safety, many jump starters won’t deliver power unless they detect a battery with a minimum voltage (e.g., 2-3 volts). If your truck’s battery is completely dead (0 volts), the starter’s safety system may not activate. The ‘manual override’ or ‘boost’ button bypasses this safety detection, forcing power to the clamps. This allows you to start a vehicle with a deeply discharged or dead battery, but it should be used with caution as it often deactivates safety features like spark-proofing.
Conclusion: Our Final Recommendation
After rigorous testing and careful consideration of real-world user feedback, we confidently stand by our top pick. The NOCO GB70 2000A Jump Starter is the best all-around choice for the vast majority of diesel truck owners. It provides the raw power needed to reliably start up to 6.0L diesel engines, even in challenging conditions. Its rugged, IP65-rated construction ensures it can withstand life in a work truck, while its foolproof safety features provide invaluable peace of mind. By combining formidable starting power with practical features like a power bank and a bright flashlight, the NOCO GB70 proves itself to be more than just a tool—it’s essential emergency equipment.
