DuroStar DS4850EH 4850 Watt Portable Generator

There’s a very good reason why most engines run on diesel – it’s safer than pretty much any gas or fuel in more ways than one. Diesel fuel does not ‘spark’ when you ignite the engine, plus diesel burns at lower temperatures, preventing wasted resources and optimizing your long-term costs.

If you value safety and efficiency above everything else and are looking for a power generator, we warmly recommend using a diesel-powered one.  Today we intend to give you some insight regarding the benefits of diesel generators and provide you with our selection of the top 5 best portable diesel generator models that money can buy.

Let’s start: Why should I consider buying a portable diesel fuel generator?

In earlier days of diesel-type generators, people kept using them despite the many shortcomings they brought to the table – a diesel generator used to be incredibly loud, not to mention that organizing storage units was almost as expensive as diesel itself a couple of decades ago.

Nowadays these generators have gotten cheaper; the outdated spark-plug technology was replaced with improved start-up mechanisms, and the once loud and bulky generators were updated in terms of size and quietness.

The main fields where diesel generators dominate other generator types are safety and reliability. Models that belong to this category are substantially safer to use due to low-temperature fuel burning and the complete absence of sparks once the engine starts running.

Furthermore, diesel generators are purposefully designed to be sturdier and more resilient to extreme temperatures as well as physical damages. Our topic of today is about the freshest state-of-the-art diesel generators that are both smaller and more transportable in comparison to their huge, heavy predecessors, so let’s have a look at the best portable diesel generators in 2021. The power, the items await below, along with a few free tips for any respected buyer.

Best Overall Generator – DuroStar DS4850EH 4,850 Watt Portable Generator

The main reason why DuroStar’s DS4850EH is probably the best portable diesel generator on the current market is that it encompasses everything a well-rounded generator should – it’s not overly pricey, it’s sufficiently strong, and it’s laden with a myriad of utility features that help its versatility.

In terms of compactness, the DuroStar’s DS4850EH features two sturdy wheels and a retractable carry handle other generators don’t offer. Even though it weighs approximately 132 pounds it’s still very easy to transport from point A to point B, making it easier for shipping, especially in America.  Moreover, most diesel generators are pretty noisy, but DuroStar’s DS4850EH emits only 69 decibels.

Portable Diesel Generators Buying Guide – How to Start, Fuel, Gas, and More

This section contains a brief guide with all the info you’ll need to find the best diesel portable generators; before you make the final decision, consider the following factors that can help you determine what size generator you need.

Start with size and storage of a portable diesel generator

Portable generators are often equipped with rolling wheels as one of the key parts for portability. However, you should also take size into consideration when making plans for storage. An ideal place where you can store your diesel generator should be a dry, isolated area – preferably a shed or a basement.

Power generator capacity

Diesel driven generators are dominantly used in the industrial sphere; this means that the selection of heavy-duty models is fairly larger when put back to back with the global catalog of light-duty models. Even though weaker (and cheaper) models are a relatively rare find, we’ve made sure to include a couple on our list of the best portable diesel generator models.

Noise produced by the generator

Some of the earliest diesel category generator models were nearly deafening; however, newer models have come a long way and are now much closer in this field when compared to propane generators, gas generators, and inverter generators. A standard diesel-powered generator emits approximately 80 decibels of noise, although quieter models aren’t so hard to find.

Eco-friendly generator options – stay off the bad gas and fuel, take the green start

Diesel is one of the most polluting fuel types you can find – even when compared to petrol. However, most modern generators that run on it are equipped with eco-friendly filters that significantly reduce these emissions. Even though eco-friendly diesel generators may cost a bit more, they’re worth investing in.

Quality of generator wheels – keep it portable

Most diesel-type generators are fairly heavy, so having a set of sturdy wheels equipped with your model is very important, especially for easier shipping. Machines supplied with flimsy wheels are easy to notice – small, slim tires and the material used in the construction process of the wheels are dead giveaways in terms of portability and shipping of the products.

Conclusion – The solutions are in the air

While diesel generators might be just a bit more demanding in terms of maintenance and fuel cost, they’re ultimately superior in sturdiness, reliability, ease of shipping, and cost-effectiveness. We hope that our selection of the best portable diesel generator models served you well in finding the one that can best cater to your needs and that you’ve learned what makes these generators best for you.
