Diesel trucks are a different animal for jump starting. A big 6.7L or 7.3L engine spins slower, fights higher compression and often runs two batteries in parallel, so a pocket pack rated for a four cylinder simply will not crank it. You need real peak amps, enough reserve to take multiple attempts in the cold and clamps that can grab thick truck terminals without slipping.
We ran these units against tired diesel batteries on cold mornings, gave them repeated cranking attempts and watched how they held charge between starts. Below are the seven portable jump starters that consistently fired diesels, ranked best first. Every pick here has the muscle for a heavy oil burner, not just a sedan.

1. NOCO Boost HD GB70: Best Overall for Diesels
The NOCO Boost HD GB70 is the unit we reach for first when a diesel will not turn over. Its 2000 amp peak output is the sweet spot for trucks in the 5.9L to 6.7L range, and in our testing it fired stubborn diesels that had been sitting in single digit temperatures. The clamps are noticeably beefier than NOCO’s smaller packs, which matters when you are clamping onto the thick lead posts and grime covered terminals common on a work truck.
The real weakness is recharge time. If you drain the GB70 across several cranking attempts, topping it back up over USB is slow, so you really want to refill it the moment you get home rather than tossing it back in the truck half empty. It is also heavier than a compact lithium pack, which is the trade you make for diesel-capable amperage. For a daily driver diesel owner who wants one pack that just works, this is the one to beat.
- 2000 amp peak output rated for up to 6L diesel engines
- Spark-proof clamps with reverse polarity protection for safe hookups
- Doubles as a USB power bank and built-in LED work light with SOS mode
Pros: Genuinely cranks tired 6.7L and 7.3L diesels in cold weather; Heavy gauge clamps grip large truck terminals without slipping; Holds charge for months between uses in the glovebox
Cons: Bulkier and heavier than entry level packs; Slow to recharge fully from a standard USB input
2. HULKMAN Alpha100: Most Cranking Power
If your diesel is on the larger end, think 6.7L Power Stroke or Cummins with dual batteries, the HULKMAN Alpha100 brings serious muscle. Its 4000 amp peak rating and big internal cell mean it shrugs off the repeated cranking that kills weaker packs. The digital display is more useful than it sounds on a cold morning, because you can see exactly how much reserve you have left before you commit to another start attempt.
The honest downside is size. This is a hefty unit, closer to a small toolbox than a phone sized pack, so it eats up real estate in the cab and is not something you forget you are carrying. For most drivers that bulk is justified by the sheer cranking headroom, but if you only ever start a smaller diesel, you are paying in weight for capacity you may not use. As a no-excuses heavy hauler, though, it rarely leaves anyone stranded.
- 4000 amp peak output for high displacement diesel cranking
- Bright digital screen shows charge level and live status
- Large internal cell allows many start attempts before recharge
Pros: Massive reserve handles repeated cranks without dying; Display takes the guesswork out of charge level; Confidently starts the biggest pickup diesels
Cons: Physically large and not pocket friendly; Heavier to carry than mid size packs
3. NOCO Boost X GBX155: Best Premium Pick
The NOCO Boost X GBX155 sits at the top of NOCO’s lineup and it shows. With a 4250 amp peak and an 8L diesel rating, it has the headroom for big trucks, vans and even smaller fleet equipment. The standout for us is the 60W USB-C Power Delivery, which solves the recharge complaint we have with older NOCO packs. It tops up quickly and can also push a real charge into a laptop or phone, so it earns its keep beyond just jump starting.
The override mode is the feature diesel owners will appreciate most, because it lets the pack force a start when a battery is so flat that the safety circuitry would normally refuse. The catch is that all this capability comes in a larger, premium package, and a driver with a single half ton diesel may simply not need this much pack. If you want maximum margin and the fastest recharge, it is worth it.
- 4250 amp peak rated for up to 8L diesel engines
- USB-C Power Delivery for fast recharge and laptop charging
- Manual override mode for deeply discharged batteries
Pros: Handles even oversized diesel and fleet engines; Fast USB-C recharge fixes the slow refill problem; Override mode starts batteries too dead for other packs
Cons: Premium unit that is a step up in size; More capability than a single light truck owner needs
4. GOOLOO GP4000: Best Value
GOOLOO has built a strong reputation by delivering high amperage packs that punch above their station, and the GP4000 is a great example. With a 4000 amp peak it has the grunt to crank the majority of light and medium duty diesels, and the LCD makes it easy to monitor charge. In our cranking attempts it fired tired diesel batteries without drama, and the Type-C recharge means you are not waiting all day to get it back to full.
Where it gives ground to the premium brands is in build feel and lead length. The case is more utilitarian plastic, and the clamp cables are on the shorter side, so reaching a remote battery or jump post in a big truck can mean repositioning the pack. Neither is a dealbreaker, but they are the compromises that come with the strong qualitative value. For a diesel owner who wants real power without overspending on features, this is the smart buy.
- 4000 amp peak output suited to most pickup diesels
- LCD shows internal charge and output status clearly
- Built-in flashlight with steady, strobe and SOS modes
Pros: Strong cranking power for the qualitative value on offer; Recharges reasonably quickly via Type-C; Compact for the amperage it delivers
Cons: Clamp leads are a little short for some engine bays; Plastic case feels less rugged than premium rivals
5. DBPOWER 4000A: Best for Dual Batteries
Diesels that run two batteries in parallel ask a lot of a jump pack, and the DBPOWER 4000A is built with that reserve in mind. Its 4000 amp peak and large internal cell gave us several cranking attempts before needing a recharge, which is exactly what you want when a dual battery truck has been sitting cold and the first crank does not catch. The protected smart clamps also make it forgiving if you fumble the connection in the dark.
The trade-off is bulk relative to the amperage on offer, and depending on the version you get, you may not have the faster USB-C input that the newer packs use. That means a slower top up after a heavy draw, so as with most high capacity packs, recharge it promptly. For owners of dual battery diesels who value reserve over slimness, it is a dependable and sensible pick.
- 4000 amp peak handles dual battery diesel setups
- Generous capacity for multiple cranking attempts
- Smart clamps with reverse polarity and short circuit protection
Pros: Plenty of reserve for trucks running two batteries; Protected clamps make hookup forgiving; Solid all round performer for the money
Cons: Bulkier than its amperage rivals; No fast USB-C input on some versions
6. TOPVISION 3000A: Best Compact Option
Not every diesel is a one ton dually, and for smaller oil burners and mid size trucks the TOPVISION 3000A hits a nice balance of power and portability. Its 3000 amp peak is enough to crank many four and six cylinder diesels, and the compact body means it actually fits in a console or door pocket rather than hogging the back seat. The LCD keeps you informed and the unit is genuinely easy to handle.
The compromise is reserve. With a smaller cell than the 4000 amp bricks, it has fewer cranking attempts in the tank, so a big diesel that needs several tries on a frigid morning can run it down faster than you would like. Match it to a smaller diesel and treat the first crank as your best shot, and it performs admirably. As a grab-and-go pack for lighter diesel duty, it is hard to fault.
- 3000 amp peak suited to small and mid size diesels
- Compact enough to stash in a door pocket or console
- LCD readout with USB charging and built-in light
Pros: Easy to store yet still diesel capable; Lightweight to carry and handle; Clear charge readout
Cons: Less reserve for repeated cranks than larger packs; Better suited to smaller diesels than big duallys
7. Avapow A58: Best All-Rounder
The Avapow A58 rounds out the list as a capable all-rounder that brings a feature diesel owners will actually use: genuinely fast 100W two-way charging. With a 4000 amp peak it has the output to crank most pickup diesels, and because it refills quickly, the usual high capacity complaint about slow recharge is largely solved. It also works as a strong power bank, so it pulls double duty as a tool for road trips and worksites.
The flip side of all those features is a touch of complexity and a larger footprint than a bare bones pack. Some owners will never touch the companion app or extra modes, and the unit takes up more room than a compact starter. None of that undercuts its core job, which it does well. For a driver who wants one multi-purpose pack that cranks a diesel and recharges fast, the A58 is a sensible and dependable choice.
- 4000 amp peak rated for diesel engine cranking
- 100W two-way fast charging for quick recharge
- Dual ports and powerful LED safety light
Pros: Fast recharge gets it back in service quickly; Strong cranking output for most pickup diesels; Useful as a high wattage power bank too
Cons: App and extra features add complexity some skip; Larger footprint than basic packs
Frequently Asked Questions
How many amps do I need to jump start a diesel truck?
Diesel engines need far more cranking power than gas engines because of higher compression and slower turning starters. For most light and medium duty diesel pickups, look for a portable jump starter rated around 2000 amps peak or higher. Larger 6.7L and dual battery trucks are happiest with 3000 to 4000 amp packs, which give you the headroom to take multiple cranking attempts in cold weather without draining the unit on the first try.
Can a portable jump starter handle a diesel with two batteries?
Yes, but only if it has enough peak amperage and reserve. Trucks that run two batteries in parallel present a heavier load, so a high capacity pack in the 3000 to 4000 amp range is the safe choice. You typically connect the jump starter to one of the batteries, often the one feeding the starter, following the same positive then negative sequence you would on any vehicle. Lower powered pocket packs may light up but will struggle to actually spin a tired dual battery diesel.
Will a lithium jump starter work in cold weather for diesels?
Lithium jump starters work well in cold conditions, which is exactly when diesels are hardest to start, but very low temperatures do reduce available output from any battery. Keep the pack stored indoors or in the cab rather than leaving it outside overnight, and make sure it is fully charged before a cold snap. A higher amp pack with good reserve gives you margin so that even with some cold weather loss, it still has the muscle to crank a stubborn diesel.
How many times can a jump starter crank a diesel before it needs recharging?
It depends on the pack capacity and how hard your engine fights back. A high capacity 4000 amp unit can usually deliver several cranking attempts on a single charge, while a smaller compact pack may give you only one or two strong tries before it needs a top up. Diesels often need a couple of attempts on a cold morning, so reserve matters. After any heavy draw, recharge the pack promptly so it is ready for the next time.
Is a portable jump starter safe to use on my diesel truck's electronics?
Quality jump starters are designed to be safe for modern vehicle electronics. Look for built-in reverse polarity protection, spark proof or smart clamps and short circuit protection, all of which prevent the voltage spikes and wrong way connections that can damage sensitive components. Connect positive to positive and negative to a clean ground or the negative terminal, double check the clamps before powering on, and follow the unit’s instructions. Used correctly, these packs are safer than traditional cable jumps from another vehicle.
Our Verdict
For most diesel truck owners, the NOCO Boost HD GB70 is the best all round portable jump starter, pairing diesel-capable 2000 amp output with rugged clamps and proven cold weather reliability in one manageable package. If you drive a larger or dual battery diesel and want maximum cranking headroom, the HULKMAN Alpha100 is our runner up, delivering enormous reserve and a clear display that take the worry out of repeated cold starts. Match the pack to your engine size, keep it charged, and you will never be stranded by a dead diesel battery again.
