Best Jump Starter For Diesel (Identifying Factors)

Do you know what the problem is with diesel engines? They don’t start up as easily as gas engines. This is where a good jump starter for diesel comes in handy.

But, to make sure that you get the best jump starter for your needs, there are a few factors that you should consider before making a purchase. 

We will go over them below to keep reading and see if they sound like they would be perfect for your situation.

We all know that the main part of the car is the battery. Without the correct battery, you will not be able to start your vehicle. 

In case of an emergency, while driving, you might want to keep the jumper wires in the glove compartment or another storage space. But, nowadays, there are lots of other options for jump-starting your car. Here are some:

A generator

This option is great for large garages and those who need access to power even when the main power goes out.

They are designed to be used just like an outlet. They can be plugged into a nearby running car’s battery or just plugged into a wall socket if available. 

A Booster 

This is the most popular type of jump starter for cars. They’re small enough to fit in the trunk of your car or a tool shed. They use your car’s battery and the engine’s alternator as a power source. 

The charging happens while you are driving; therefore, they use less time than other options. They are portable and can be used to jump-start your car immediately.

A power inverter 

This is similar to a generator in that it uses your car’s battery to charge its built-in battery.

Still, it is different in that it recharges the battery from the electrical device itself (the cigarette lighter). This is good because you can use your cell phone while the car is being jump-started.


The inverter type of jump starter might be ideal for somebody who doesn’t need a portable one that they can carry all day long. It is stationary, meaning it has an AC outlet built into its design. 

This means, if there’s no power available outside, you could still use this device indoors after hooking up extension cables from the inverter’s outlets to another car with 12VDC batteries.

A Charger

Some chargers are simple, portable jump starters for cars and those that happen to be smaller and more powerful than other options.

Most car batteries come with quick-charge capability already installed when they were manufactured. 

It’s a matter of learning how to access it and working the settings to make it work for you when you need it right away.

So, what goes into making a car battery? 

There are two types of batteries in today’s autos: flooded batteries and sealed lead-acid batteries (SLA).

Factor # one: What are you trying to start? 

Diesel engines can be challenging, so if your car is a diesel vehicle, then that’s the first thing you should keep in mind. 

But also consider what type of engine you want to jump-start with this device (gas vs. diesel)?

Gasoline engines will require a lot more power than their diesel counterparts because they have much less torque and don’t need as many RPMs to get moving. 

You’ll need an ample amount of amps for gas motors while only needing around 20 for most diesel – but exceptions are depending on the make and model.

Factor # two: How often would you use it? The frequency of how or when you might use a starter like this will be important to consider. 

Suppose you are going to use your starter one or two times a year. In that case, the cheaper models will likely work just fine for you – but if you plan on getting into heavy use, say, trying to start your car every day with this device. 

You don’t want to have something cheap break after only 30-60 days of usage and find yourself loathing where all that extra cash went! Spending more money may not be such a bad idea.

Factor # three: What size do I need? The last thing you’ll want to think about before purchasing an engine jump starter (diesel) is the size. 

If you have a smaller engine, then something with around 500 amps will be good for about 40 volts, while 600+ amps will work well if your vehicle has an 85-volt system or higher. This will not impact how many amps are in the unit and what you are trying to jump-start.


The size of the starter can also make some difference in how much power it needs.

 Gas engines require more than diesel ones, but this isn’t always true, depending on the specific model you own (like pickups).

How often would I use it? 

It would help if you keep in mind how many times per year you plan on using your device before deciding which one might suit all of your needs best. 

It’s not worth spending too little money for something that will break after only a few months of usage.

Diesel engines: diesel engines take more power to start than gas ones, so if you are looking for the best diesel jump starter, you must keep this in mind. 

There are also different sizes available depending on what size engine your vehicle has – be sure to look into these before making any purchase decisions.

Factor four: What type of car do I want to drive? 

If its a gasoline powered motor and not diesel-powered, then there won’t need nearly as many amps when starting with an electric device like a jumper or battery booster because they don’t have much torque anyway.

But if it’s a truck, bus, or another heavy-duty diesel engine vehicle, then you’ll need a lot more amps to get the job done.

The battery of a diesel engine is different than the one in gasoline engines. Diesel starts are not as easy to jumpstart, but it can be done with some know-how and equipment. 

The power required for this varies depending on the make and model of your vehicle. In general, you will need an adapter that converts from 12V DC to 100A AC, plus a heavy-duty extension cord for at least 50 amps or more.

 If your car has been sitting idle for a while (ease up gradually). It would help if you had gloves and eye protection since jumping a diesel takes longer due to the higher voltage requirements needed by diesel.

You also should get jumper cables that can handle at least 40 amps or preferably more. With all these items handy, some work is to be done before you can jump your car.

Next, attach that same cable at the other end to an unpainted metal surface under or near the hood of each vehicle where they will not contact any painted surfaces. This connection should only occur for five seconds max.

 Once cables have been attached securely while also ensuring no paint has been damaged, turn the engine of one car on and then back off.

Please wait a few seconds before turning the other vehicle’s engine on after you’ve turned it off). 

If your diesel jumps start immediately after this point in time, then congratulations! If it’s still dead after this point in time, stop immediately; repeat these steps with more power (add 50 amps) or move vehicles closer together).

If not, that means there is something wrong with either your battery or alternator, so now you’ll have to call for help from an auto mechanic.​​

Portable Jump Starter: 

The most popular jumper type is probably the mobile one because it serves as a great backup tool since it can be easily carried when not needed.

The battery is usually lithium-ion, and it’s a good idea to keep the jumper in your trunk or backseat so you can get it quickly.

Some diesel jumpers can also be used for gasoline engines, but they are not as powerful. Diesel jumping cables should always have a higher amp rating than cable lengths.

 To ensure that each battery is being fed enough power all the time; this will help improve the chances of starting up your car successfully.

What is the best diesel vehicle for you?

The question may seem trivial when people are looking for a new vehicle. Still, it depends on your specific needs and preferences. When purchasing a diesel engine, you can select from diesel cars, SUVs, trucks, and vans.

In Conclusion

If you’re still having problems with the information above, try using another vehicle or adding more volts through an inverter for a portable jumper. 

If none of those work and call for the professional help from an auto mechanic instead – it might mean there’s something wrong with either one of your batteries or alternator.
