4. Clore Automotive Jump-N-Carry JNC660: Best Heavy Duty Lead-Acid
The Clore JNC660 is a classic heavy duty jump pack favored by mechanics and fleet operators. It uses a sealed lead-acid battery with 22Ah capacity and 1700 peak amps, capable of starting the largest diesel engines. The unit is built like a tank, with a tough case and heavy-duty clamps. Owner reviews consistently praise its reliability in professional settings.
However, this jump pack is very heavy (over 18 pounds) and not portable for everyday use. Lead-acid batteries also require more care than lithium: they need to be kept charged and can sulfate if neglected. If you need a jump pack for occasional personal use, a lithium model is lighter and easier. But for heavy duty, daily professional use, the JNC660 is a workhorse.
- 1700 peak amps for diesel and large gas engines
- 22Ah sealed lead-acid battery, very durable

However, this unit is extremely heavy and cumbersome to carry, making it impractical for personal use or emergency roadside assistance. The price is also high relative to its peak amp output compared to lithium models. If you need a jump pack for occasional personal use, a lighter lithium unit is better. But for a shop environment where durability is paramount, the Schumacher is a solid investment.
- 1350 peak amps for diesel and gas engines
- Sealed AGM lead-acid battery, long service life
- Professional-grade clamps and cables
Pros: Very durable and built to last; Reliable for frequent use in shops; High reserve capacity
Cons: Very heavy (over 20 pounds); Expensive for the peak amp rating
Frequently Asked Questions
What peak amp rating do I need for a heavy duty jump pack?
For heavy duty applications, such as diesel trucks or large SUVs, we recommend a jump pack with at least 1000 peak amps for gasoline engines and 1500+ peak amps for diesel. Larger diesel engines (6.0L+) may require 2000 peak amps or more. Always check your vehicle’s engine size and type before purchasing.
Are lithium jump packs better than lead-acid for heavy duty use?
Lithium jump packs are lighter, more compact, and hold their charge longer. They are ideal for portable emergency use. Lead-acid jump packs are generally more durable and can deliver sustained high current, making them better for professional shops or extreme cold. However, they are much heavier and require periodic charging.
Can I use a heavy duty jump pack to charge my phone or other devices?
Yes, most modern jump packs include USB ports for charging smartphones, tablets, and other small electronics. Some models also have 12V DC outputs. However, heavy duty jump packs prioritize starting power, so the USB output may be limited. If device charging is important, look for a model with USB fast charging (QC 3.0).
How do I maintain a heavy duty jump pack?
For lithium jump packs, recharge them every 3-6 months to prevent battery degradation. For lead-acid models, keep them fully charged and use a maintainer if stored long-term. Store the jump pack in a cool, dry place. Always follow the manufacturer’s instructions for charging and storage to extend battery life.
What safety features should I look for in a heavy duty jump pack?
Look for spark-proof technology, reverse polarity protection, over-voltage protection, and short-circuit protection. Some models also have thermal protection and low-voltage cutoff. Certified safety features (such as UL or CE) provide additional assurance. Avoid cheap models without clear safety certifications.
