1. NOCO Boost HD GB70: Best Overall
The NOCO Boost HD GB70 pushes 2000 peak amps, giving it the muscle to crank diesel pickups up to 6 liters even after the battery has gone flat. Its heavy-gauge clamps and oversized cables move serious current without sagging.
Safety features like spark-proof connections and reverse polarity protection make it forgiving for first-time users. The rugged enclosure shrugs off the abuse of a truck toolbox or job site.
- 2000 peak amps for big diesel engines
- Spark-proof clamps with reverse polarity protection
- Boosts gas engines up to 8L and diesels up to 6L
Pros: Strong cranking output for large diesels; Rugged housing built for shop and trail use
Cons: Heavier than compact pocket units
2. NOCO Boost X GBX155: Most Powerful
The NOCO Boost X GBX155 brings a massive 4250 peak amps, putting it at the top end for cranking heavy diesel trucks and equipment. That huge reserve means it laughs at cold starts that stall smaller units.
Beyond starting power, the 65W USB-C port turns it into a capable charger for laptops and phones. UltraSafe clamps keep the connection clean and protected from sparks.
- 4250 peak amps for the toughest diesels
- UltraSafe spark-proof clamp technology
- 65W USB-C in and out for fast device charging
Pros: Enormous cranking reserve for dual-battery diesels; Doubles as a high-output power bank
Cons: Larger footprint takes more storage room
3. Hulkman Alpha100: Best Value
The Hulkman Alpha100 delivers 2000 amps backed by a big 28000mAh cell, so it keeps cranking diesel pickups through multiple attempts. The bright color LCD reports remaining charge and start readiness at a glance.
It strikes a strong balance of power and capacity for owners who start cold engines often. The smart clamps add reverse polarity and short-circuit protection for peace of mind.
- 2000 amp output for diesel and gas engines
- Color LCD shows charge and start status
- 28000mAh capacity for repeated cranks
Pros: Large battery handles many starts per charge; Clear display makes monitoring easy
Cons: Charging the unit fully takes time
4. Gooloo GT3000: Best High Amp
The Gooloo GT3000 offers 3000 peak amps and the claimed reach to start diesel engines up to 8 liters, making it a strong match for big pickups. That headroom helps when batteries are weak in deep cold.
An integrated LED work light with several modes is welcome during nighttime breakdowns. Layered safety protections guard against overcurrent, overheating, and reverse polarity.
- 3000 peak amps for large displacement diesels
- Starts engines up to 10L gas and 8L diesel
- Built-in LED work light with multiple modes
Pros: Big cranking number for heavy diesel rigs; Handy LED light for roadside work
Cons: Clamp cables are a touch short
5. Schumacher DSR ProSeries DSR114: Pro Grade Pick
The Schumacher DSR ProSeries DSR114 is engineered for professional use, with a lithium pack tuned to crank big diesel and fleet vehicles. It is the kind of unit techs reach for when a row of cold trucks needs to move.
The rugged housing and heavy clamps stand up to daily shop abuse. Its high output makes light work of large displacement engines that defeat lighter consumer units.
- Lithium pack tuned for heavy duty starts
- Cranks big diesel and fleet vehicles
- Rugged professional grade housing
Pros: Built for shop and fleet duty cycles; Durable clamps and cabling
Cons: Premium build adds weight
6. Avapow A58: Best Cold Start
The Avapow A58 advertises a 6000 amp output aimed squarely at extreme cold starts, where diesel batteries struggle most. That brute force gives it confidence against stubborn big-displacement engines.
Dual USB ports and a bright flashlight add roadside utility on dark winter nights. Built-in protections cover reverse polarity, short circuits, and overcharge to keep starts safe.
- 6000 amp output for extreme cold starts
- Starts large gas and diesel engines
- Dual USB outputs plus bright flashlight
Pros: Huge amp rating for frigid mornings; Plenty of capacity for repeated attempts
Cons: Bulkier than midsize units
Frequently Asked Questions
How many amps do I need to jump start a diesel truck?
Diesel trucks crank harder than gas cars, so look for at least 1500 to 2000 peak amps for most pickups. Big-displacement or dual-battery diesels in cold climates do best with 2000 amps or more for reliable starts.
Can one jump starter handle a dual-battery diesel?
Yes, a high-amp lithium unit can crank a dual-battery diesel when it has enough peak output and capacity. Connect to the main starting battery and pick a model rated for the engine displacement to be safe.
Do jump starters work in very cold weather?
They do, though cold reduces battery performance, so keep the unit charged and stored somewhere warmer when possible. Models with high amp ratings and cold-rated cells give the best results on freezing mornings.
Our Verdict
For diesel pickups the priority is raw cranking power, and the NOCO Boost HD GB70 leads our list for its blend of high amps, rugged build, and safety features. If you face dual-battery rigs or brutal cold, step up to the higher-amp NOCO Boost X GBX155 or Avapow A58 for extra reserve.
