1. NOCO Boost Plus GB70: Top Pick
In our evaluation the NOCO Boost Plus GB70 stood out for its impressive 2000A peak current, which comfortably exceeds the requirements of most diesel trucks up to 6.0L. The unit also earned high marks for durability and safety features such as reverse polarity protection.
Its only notable weakness is the modest USB-C output, which may not satisfy users who need to charge multiple devices simultaneously. If you prioritize a built‑in air compressor, this model may not be the best fit.
- 2000A peak for rapid starts
- Built-in LED flashlight with SOS mode
- USB-C port for device charging
Pros: High peak power; Compact design; Reliable brand reputation
Cons: Limited USB output; No built-in air compressor
2. GOOLOO 800A Peak: Best for High Power
Our research shows the GOOLOO 800A Peak delivers solid performance for diesel engines up to 5.0L, with an easy‑to‑read LCD that keeps users informed of charge levels. The inclusion of a 12V accessory socket adds convenience for on‑the‑road power needs.
The main limitation is its lower peak amperage compared with the top pick, which may result in slower cranking on larger diesel engines. Users with very heavy trucks might prefer a higher‑current model.
- 800A peak suitable for small diesel trucks
- LCD display shows battery status
- Integrated 12V car socket
Pros: User-friendly LCD; Affordable price point; Multiple charging ports
Cons: Peak current lower than top pick; Bulkier than some competitors
3. DBPOWER 800A Portable Jump Starter: Best Value
We found the DBPOWER model balances performance and price, offering an 800A peak that meets the needs of most mid‑size diesel pickups. Its dual USB ports and three‑mode flashlight add practical utility for roadside emergencies.
The lack of an automatic safety shutoff means users must monitor the device manually, which could be a concern for less experienced owners. If safety automation is a priority, consider a model with that feature.
- 800A peak for diesel engines up to 5.0L
- Dual USB ports for gadgets
- LED flashlight with three modes
Pros: Good value for features; Durable casing; Decent battery life
Cons: No built-in safety auto shutoff; LCD screen is basic
4. STANLEY J5C09: Compact Choice
Our comparison highlighted the STANLEY J5C09 for its portable form factor combined with a respectable 1200A peak, enough to start most diesel engines under 5.5L. The ergonomic grip makes it easy to hold during a jump.
However, the unit’s battery capacity limits repeated use without recharging, and the absence of a built‑in flashlight may inconvenience users who need illumination during night‑time emergencies. Those needing extended multi‑start capability might look elsewhere.
- 1200A peak current
- Integrated 12V accessory socket
- Compact ergonomic grip
Pros: Higher peak than many rivals; Ergonomic handling; Trusted brand
Cons: Battery capacity limited for multiple starts; No LED flashlight
5. Schumacher DSR Pro: Heavy Duty Option
In testing the Schumacher DSR Pro delivered a strong 1500A peak, suitable for heavier diesel trucks and commercial vehicles. The heavy‑duty clamps and built‑in power outlet provide practical versatility for workshop use.
The trade‑off is its bulkier dimensions and increased weight, which limit true portability. If you need a compact unit for occasional roadside assistance, a smaller model may serve you better.
- 1500A peak for larger diesel engines
- Heavy duty clamps with insulated handles
- Built-in 12V power outlet
Pros: Robust build; High peak for heavy trucks; Safety clamps
Cons: Larger size reduces portability; Higher weight may be cumbersome
6. Audew 1500A Jump Starter: Budget Friendly
Our assessment found the Audew 1500A offers a high peak current at a price that appeals to budget‑conscious buyers, and the added LED work light is handy for low‑light situations.
Under frequent heavy‑load usage the battery tends to lose capacity faster than premium competitors, and the lack of an LCD display means users cannot see precise charge levels. If you need precise monitoring, consider a model with a digital interface.
- 1500A peak for reliable diesel starts
- LED work light with three brightness levels
- USB port for phone charging
Pros: Strong peak amperage; Included work light; Competitive price
Cons: Battery life degrades faster under heavy use; No LCD indicator
7. PowerShot 800A Portable Jump Starter: Versatile Performer
We found the PowerShot unit to be a well‑rounded choice, combining a respectable 800A peak with a built‑in tire inflator and SOS flashlight, making it a convenient all‑in‑one emergency tool.
The added inflator increases overall weight, and the peak amperage, while adequate for many diesel pickups, may fall short for larger engines. Users with heavier trucks should verify the amperage meets their vehicle’s requirements.
- 800A peak suitable for most diesel pickups
- Built-in 12V tire inflator
- LED flashlight with SOS mode
Pros: Multi‑function utility; Easy one‑button operation; Solid safety features
Cons: Inflator adds extra weight; Peak amperage lower than top tier
Frequently Asked Questions

How often should I charge my jump starter?
Manufacturers recommend charging after each use and at least once every three months if stored unused, to maintain optimal battery health.
