7 Best Jump Starters for Diesel – (Reviews & Guide 2021)

If you ride a lot, and you own a mightier vehicle such as a diesel truck, the chances are that you are going to need the best jump starter for diesel sooner or later. A jump starter is something you can live without until it’s the only thing that can save you out there on the road. Investing in safety on the road is something we all should do.

When the battery gets depleted suddenly (which can happen due to all sorts of reasons), a jump starter will get you home. Larger vehicles need more power, but there are nuances to different jump starters, even for diesel engines. That’s why I prepared this guide for you, to help you get a hold of the whole topic and make a valuable decision in the end. A little knowledge can go a long way, not only safety, but also money-wise. Let’s dig in!

See The Quick Comparison Chart

What Size Jump Starter Do I Need?

Best Jump Starters for DieselThere is no straight answer to this question because no two vehicle models are the same, and every other engine has different specs. However, we can safely say that there are some specs that can tell us how big of a vehicle a certain jump starter can start. The main three power ratings you can find on a jump starter are:

  • Peak amps
  • Cranking amps
  • Cold cranking amps

The consensus among truck drivers is – the more amps the better (we will get to it in a moment). But you should keep in mind that a jump starter with more amps usually comes with a bigger housing as well. So, the bigger the better stands as correct here, but there is also overkill on the other side.

1. Peak amps

This is the amperage (or Amps for short) that gets advertised the most. If we were to avoid tech speak, we could say that the peak Amp rating represents the highest amperage that the jump starter can achieve. Most typically, this “burst” of current is at the very beginning of the process.

The peak Amp rating varies from model to model, and, depending on the size of the engine, a jump starter for diesel engines can fluctuate from 400 amps to more than 2000 amps. This may look like overkill, but there is a reason for such a strong peak amp rating, even though fewer amps may get the job done in the first place. The amperage also depends on the temperature around your battery.

2. Cranking amps

Cranking or working amperage comes as a lesser important spec, for the most part. Cranking amp rating tells us about the sustainable power that a jump starter discharges while you are using it. In most cases, this cranking amp period lasts about 30 seconds.

Even though peak amps get the job done when it comes to jump starting your diesel vehicle, cranking amp rating is important as well. Again, we are talking about temperature.

3. Cold cranking amps

As the name suggests, cold cranking amps give us the real perspective of how the jump starter would behave in freezing temperatures. To be exact, in most cases the cold cranking amp rating is done at the temperature of 0° F (or -18° C).

Due to the nature of batteries and the materials they are made of, lower temperatures negatively affect jump starters as well. That is why, if you live and drive in areas that get harsh, icy-cold winters, you should definitely have this stat in mind.

4. Physical Size

Last, but not least, when it comes to the “how big…” topics, we should mention that jump starters for diesel vehicles (generally) come in two types and designs:

  1. Old battery system jump starters – bulkier and more reliant in freezing temperatures
  2. Newer battery system jump starters – small devices that usually come with a lot of extra features

Be aware of one fact, though – the size of the jump starter does not always correlate to the peak amperage. Simply decide how much storage space you can spare for the new jump starter and start from there.

5. Battery Type

This is less and less of a concern since the tech is rushing towards a lithium battery system standard. But we must touch on the issue because batteries are essentially chemical reactors, and jump starters for diesel may come in two main forms of batteries:

  1. Lithium-ion batteries – lightweight and generally safer for the user
  2. Lead-acid batteries – stronger and arguably more durable, but are also more toxic than Li-ion ones

When deciding on a jump starter you want to get for your diesel vehicle, you should probably check your state’s laws regarding batteries. Some states like California are working towards eliminating the usage of lead-acid batteries due to their harmful effect on the environment. However, the jump starters do not pose a threat if handled properly. It is the disposal of the battery after years of use that is the issue there.

Gasoline vs. Diesel Jump Starters

The real difference between gasoline and diesel jump starters is their overall strength.

Let me rephrase, the differences come from peak amperage ratings and such specs, but a lot of jump starter models come with the quality of life features that benefit a certain niche of people. People that ride powerful diesel weapons usually spend a lot of time off the road. This is why you can see a lot of powerful jump starters for diesel engines with features like LED lights or even USB charging ports.

So, to round all the differences up, we could say that the main differences between gasoline and diesel jump starters are:

  • Raw power, calculated in amperage. Jump starters for diesel engines are typically stronger and often offer a 2-battery 24V support
  • Jump starters made for diesel vehicles come with larger casings and a more industrial overall design.
  • Extra features are also more likely to be found in more powerful jump starters thanks to the outdoor-ish habits of drivers.

Jump Starters for Diesel Buying Guide

As you can see, there are all these nuances when it comes to jump starters for diesel vehicles. The technology of today allowed for jumps starters with different features to arise. However, the jump-starting feature is what they all have in common, so we will start this guide with the most important thing – amperage, or peak amperage to be exact. If you are into vehicles and are looking to renew your tools or equipment, feel free to browse the car library I prepared. Let’s see what else is there.

1. Amp Ratings

A high peak amp rating is something you should be looking for, especially if you want to jump start a diesel truck. So, without going through the whole concept again, let’s recap:

  • Peak amps – the most important feature with jump starting. Aim for the highest one you can get, especially if you drive a truck with a 24 V battery system.
  • Cranking amps – the current amperage for the next 30 or so seconds. The cranking amp rating is more important if you live in a cold area.
  • Cold cranking amps – a rating that tells us how the jump starter behaves under a freezing temperature of 0° F or -18° C. Cold temperatures negatively affect amperage from a jump starter.

The more the better, that is the deal here. You can’t exactly damage your battery by jump starting it. Not unless the battery had a pre-existing flaw. Speaking of currents and batteries.

2. Voltage

Jump Starters for Diesel Buying GuideThis might not be an important spec if we talked about cars only. Larger vehicles like trucks and SUVs can have a 2 x 12V battery system. If this is the case, you should keep in mind that the peak amp gets halved if you connect the jump starter to a 24V system. So, double-check under the hood and find out what type of battery your truck is using.

Luckily, manufacturers that deal with jump starters for diesel and other, more powerful, vehicles had that in mind. Most manufacturers will emphasize whether or not their jump starter is suitable to jump start a vehicle that uses a 24V battery.

3. Weight and Size

Factoring in the actual weight of the jump starter may not seem like an essential point, but experience shows otherwise. The weight of the jump starter, as well as its size, will determine the way you use it, once the time comes that is.

There are two main types to look out for:

  • Old-school analog jump starters that are generally bulkier and require some space
  • Digital jump starter for diesel vehicles that are significantly smaller and lighter

So, if you can afford enough storage on-board, and want to have a more robust (some might argue more trustworthy) jump starter, going with analog may be a valid choice. On the other hand, if you are a fan of modern tech, a digital jump starter will do just fine. Digital units almost always have some bonus features built-in as well. Which brings us to our next topic…

4. Extra features

For starters, the extra features you can expect from a jump starter are not game-changing, per se. At most, these extra features come as the quality of life additions, and at worst, they won’t even bother you. So, what gives?

4.1. LCD display

Newer tech brought all sorts of monitoring to devices worldwide. That is the case with LCD displays. Digital jump starters usually have an LCD display to help you monitor the current charge inside. Besides the power levels, some screens enable you to measure voltage and/or amperage.

A display is not crucial in the world of jump starters for diesel vehicles, but it is always a welcome bonus that should not be considered a deal-breaker.

4.2. A Light

Because a lot of people with diesel vehicles are driven by adventurous drivers, some more advanced jump starter models come with a built-in light. For an off-road driver, having a light in the middle of nowhere can be a life-saver.

Usually, the light feature comes with jump starters that also have a charger on-board. If you do opt for such a model, please keep in mind that a simple light can drain a lot if left turned on. Only a full jump starter is a good jump starter.

4.3. Thermometer

Because cranking amps depends on the temperature around, some models come with a thermometer of some sort. Analog or digital, no matter which one you get, a thermometer helps you decide whether it’s worth it to try again or not when the first jump-starting attempt fails.

The whole reason behind a thermometer finding its place on a jump starter are the cold cranking amps. Remember, the colder it gets the harder it gets for a jump starter to do its job.

4.4. USB Charging

Lastly, we have a feature that gets integrated into jump starters more and more. Since we all started using gadgets and handheld devices like smartphones GPS devices, a USB charging port is more than necessary.

This feature gets attached to jump starters that are usually the models that have their own source (typically in the form of a separate battery). Again, be careful not to drain the battery while charging your phone, thus disabling it from helping you with the jump starting.

5. Cable Gauge

Some people might argue that – in the right conditions, any cable gauge will do. Cable gauge refers to the thickness of the metal cables that push the current to jump start the car. Similar to jumper cables, jump starter cables come in several gauges. The thicker the better is the safest path to take.

Lead-acid jump starters (old-school type) typically come with a thicker cable gauge. On the other hand, digital jump starters usually have thinner cables of the lower gauge.

*Don’t get fooled by the gauge numbering. The rule is – the lower the number, the thicker the cables, even though the logic may seem reversed at first.

How to Jump Start a Diesel?

Compared to jump starting using another car’s healthy battery, starting using a jump starter is relatively easy. Just follow these simple steps:

  1. Make sure that the jump starter is full and turned off.
  2. Connect the red cable to the positive battery terminal
  3. Connect the black cable to the negative battery terminal
  4. Turn on the jump starter as described by the manufacturer
  5. Turn the key and turn the engine on and leave it for 30 sec at most
  6. Disconnect the cables, going with the red cable first, unless the manual says otherwise
  7. Remember to recharge the jump starter

*If you own a vehicle with a 24V battery (2 x 12V), connect the jump starter to the battery with thicker cables.

Jump Starter Safety

Jump Starter SafetyWhen it comes to safety around jump starters, most of the job is done already, through reverse polarity prevention. Some older models may not have this feature, but even they give you the option to adjust the voltage and adapt it to your engine’s requirements.

Another thing to keep in mind is that the electricity that comes out of the jump starter isn’t safe. If you are inexperienced with devices like this, I recommend using anti-shock gear. You will get the hang of it eventually. Also, remember to keep the gloves and the rest of the gear with the jump starter, safely stashed in your car’s storage compartments.

If you must use the jump starter on the road, in rainy weather, practice extra caution, because the current can both harm you and damage the car’s battery.

FAQ About Jump Starters for Diesel

1. What is the difference between battery chargers and jump starters?

The name says it all. Well, almost all. While some jump starters come with an integrated battery charger, we can safely say that these two devices come with a key difference. A battery charger is designed to recharge an empty car battery over the course of several hours. Some larger batteries even take a few days to recharge.

On the other hand, we have jump starters. They deliver a high amp current that is needed to start the car immediately. So, you technically shouldn’t be able to jump start a vehicle with a battery charger. At least not if the charger comes with a jump starter.

2. What is the difference between cranking Amp and peak Amp?

We already touched upon this subject in the guide above. But a little repetition can get us a long way. After all, the peak amp rating is what you need to have in mind if when buying a jump starter for diesel vehicles.

In layman’s terms, peak amps represent the amperage needed to jump start an engine. This burst of amps can go over the needed limit, and the “the higher the better” rule applies here.

Running, or cranking amps represent a constant current that usually lasts up to 30 seconds. This is the so-called cranking time when the engine starts. All in all, this stat is more important if you live in cold climate areas, because cranking amps then get a different rating – cold cranking amps, i.e. amps with low temperatures (0° F or -18° C) accounted for.

3. How many Amps does it take to jumpstart a diesel truck?

It depends. Different trucks come with different diesel engines. Let’s say that you could technically start a smaller diesel engine with 400 amps from a jump starter. However, thanks to the “the more the better” principle, you should be liberal with this number and get a mightier jump starter.

When it comes to larger diesel trucks, we could be talking about 1000 amps or even more. This amperage is actually lower after the engine starts, but during the initial turn, it’s the peak amps that matter, because the needed amperage then at its highest.

Wrap Up

And there we go – all the essential info about the best jump starters for diesel vehicles wrapped up in a single article. This topic is wide enough, but you don’t need to be a mechanic to choose the best tool for your vehicle. On the other hand, I always insist on the good old saying – An ounce of prevention is worth a pound of cure. A starter can get you out of a hairy situation on the road, and above all, it gives you a chance to quickly resolve an issue on the go.

And, as you could see above, the is a wide range of choices to go through, so take your time and add a new utility tool to your toolbox. Stay safe on the road!
