Are you feeling tired of calling a car maintenance service while on the way just because your battery is dead?

Then, what you need is a jump starter, which can help start your engine again right on the road.

Still, there are countless products on the market with nearly the same specifications, and pushing them all aside from one by one until you eventually get the desired product is obviously not something one would enjoy.

Then, Let’s take a look at our article about the 8 best jump starters for diesel engines to route yourself through this crowded market and head straight to what you see. Into the journey, we go!!


Advantages of Using Jump Starters for Diesel


Jump starters are known to be much safer compared to battery chargers.

To be more specific, the battery charger comes with a jumper cable connecting it to your car battery.

And this little guy can be quite a troublemaker.

Lots of things can go wrong once you hook it the wrong way, which pretty much ends up with you getting hurt.

Also, a battery charger produces more amps that may lead to an electric shock.

Now, let’s move back to the jump starters Contradictory to the aforementioned chargers; some types of these devices do not connect to your battery.

Instead, your vehicle can plug directly into the starters through a 12-volt connection.

Plus, it features a reverse polarity alarm to notify you whenever the cables have entered the jacks.


Let’s talk about the size of the jump starters and the batteries.

Clearly, the former is much smaller and, thus, more compact than the latter.

Therefore, you can take it along with you anywhere you want, for a short trip to the grocery or a multi-day journey somewhere across the country.

It will not swallow up a vast space and, due to this, does not require you to rearrange your car just to make room for it.

In addition, many modern jump starters come with a LED notification to tell you when it is nearly out of energy, which is absolutely helpful in case you are going to go on a long and faraway holiday.

Low Cost

The majority of jump starters are affordable with a price range of from $20 to $150, depending on their size and capacity.

And this is not the best part,  as far as we can tell, a small jump starter is just as cheap as a battery charger and a cable – more reason why you should choose it over the other.

Furthermore, as it is portable, you can also save the cost of roadside assistance in the event of your car breaking down.

High Charging Capability

Another way to charge your diesel engine is to use a stronger battery.

Still, for a jump starter, you can use it more times, which can help to save your money.

Normally, a battery can be used 1000 times and will reduce productivity with time.

In the meantime, unlike the battery, you will not need a specialized charger to get it charged.

What is more, a jump starter can be recharged at home easily with a 220-volt or 110-volt supply, depending on each type.

Another striking advantage of a jump starter is that it can still function properly even when you have left it unused in your cars or garages for months.

Furthermore, when bringing life back to your car, it can generate a maximum current of 1700 Amps!

Plus, the extra features deserve some attention as well.

Coming along with it is a built-in automatic charger, so you can be certain that it is always in ready mode.

Besides, to aid its awesome ability to jump start a car, it is also paired with a long-lasting, durable battery that lets it release the power to the maximum extent.

However, sad as it might sound, this best jump starter for diesel engines is not without flaw.

There is a lack of light, and on this account, working with it at night might not be that easy a job.


  • Robust components
  • Heavy-duty case
  • Jump-N-Carry performance
  • Automatic recharging


  • Limited warranty policy
  • Heavy battery

#2 DBPOWER 13 Portable Car Jump Starter – Best for Multi-function

If you are looking for a portable jump starter, then this DBPOWER 13 Portable Car Jump Starter is a wonderful option!

When we saw this unit at the store for the very first time, we were very amazed by the modest size it comes in.

The whole thing is just 7.5 inches long and 3.4 inches wide, which can fit in one single palm of yours. Besides, you will not need to muster all your strength to lift it.

Despite all the cable, wires, and components packed within, it weighs just around 1.35 lbs.

Putting it next to the other jump starters is just like potting soil next to the sturdy massive rocks.

But will it actually work? Isn’t this size a little bit too… mingy to withhold some massive current?

Well, all we can say is that you should know better not to judge a book by its cover.

Believe it or not, the power output of this jump starter can be up to 2000 amps and you will find no problem starting a 6.5L diesel engine.

This means that if it is the best jump starter for 3l diesel, it is more than enough to fit the bill

In addition, it features a LED flashlight that comes in 3 modes, lighting, SOS, and strobe.

You can use this light in cases of emergencies or at night time.

Nevertheless, the item does not come with an adaptor at all (which serves as its charger if you are wondering) and you will have to get it separately. Kinda a pity!


  • Fast-charging technology
  • Quick ready time
  • Smart portable charger
  • Advanced jumper cables with LED panel


  • Semi-hard case
  • No wall adapter

The best has yet to come.

This cutting-edge unit has been built with a wide array of outstanding features, letting it do more than just restore engines’ batteries.

As a matter of fact, it is pocket-sized energy storage because it enables you to charge several USB devices, including your dear smartphone.

But will it end up overloaded, acting up, and blast us with electrical shocks if we force that huge workload upon it?

Worry not! NOCO GB150 is, fair and square, reckoned as one of the safest jump starters that have ever been launched.

Constructed with a top-notch lithium battery, it can last against all sorts of weather.

Not to mention, its specific design ensures that no spark accident will occur as it works.

This can be one of the best lithium-ion jump starters for diesel.

So, as far as we can tell, once you are using this unit, just cast away all those worries concerning sparks or getting electrocuted as none of them will take place at all.

What? Only poor-performance jump starters would come with such promise because they are so low in Amps that there is barely any current within them?

Despite coming with such a huge safety label, this device is no less powerful than those we have been talking about earlier.

Its peak amps are approximately 4000, and it can recharge any 12 Volt vehicle you have in mind.

Moreover, the LED light coming along is made in 3 modes, which are a flashlight, strobe light, and SOS light.

Hence, if you happen to get lost in the dead of the night while going somewhere off-the-beaten-path, it can totally be your lifesaver

Still, it’s being small causes a minor problem of accessing the buttons if you are wearing gloves.

  • SOS light
  • Easy-to-understand manual

What to Look For When Buying a Jump Starter for Diesel

CCA Value

CCA stands for “cold-cranking amps” which is the measurement of the ability of the battery to start the engine in cold weather.

This is seen as the power of the battery itself.

Take a car battery for example. If it has a CCA value of 450, then you should pick a jump starter with 450 CCA and more.

Vehicle Engine

What if, somehow, you fail to detect where the CCA value is located in your car?

Then you can count the number of cylinders in your vehicle engine as an alternative.

It can tell you the power requirement for jump starting.

The formulae below are formed by experienced mechanics and drivers, which are definitely trustworthy:

A 4-cylinder diesel engine requires 350 amps, while a 6 and 8-cylinder diesel engine needs 450 and 650 amps, respectively.


Normally, common vehicles come with 12-voltage batteries while this speculation for heavy-duties engines is 24 voltages.

Still, it is always essential to pick a jump starter that is higher in voltage than the battery in your vehicle requires.

This is due to the fact that sometimes, the specification is not 100% precise.

The higher voltage can, perhaps, be the one for your engine while the product with equivalent capacity might, in fact, not offer enough power.
