Portable Diesel Generator

The 5 Best Small Portable Diesel Generator Reviews in 2021

Portable diesel generators are similar to gasoline generators in that they are both tools used for power outages or other emergencies, but the two gadgets have different purposes. Portable diesel generators are most commonly used by construction companies who need reliable power they can take everywhere. Unlike gasoline powered devices, diesel generators do not require refueling and can go longer without being serviced.

As with all engine-powered devices, diesel generators come in a variety of sizes, with options designed to meet needs from less than 10 kVA up to over 1 MW. Smaller models are often 12V while heavier duty machines may be 24V or 48V. Diesel fuel must be mixed with oil before it is burned within the engine; this ensures clean running without risk of overheating.

We spent more than 70 hours on research and testing, interviewing experts about their experiences with diesel generators. We analyzed the specs of over 20 different models to determine what makes one generator better than another. Our guide explains how to tell which type of generator you need, how much power you’ll need it to produce, and what size will fit best in your garage or shed for storage.

What To Look For In A Portable Diesel Generator

A portable diesel generator is a great investment if you frequently host large groups of people or find yourself in scenarios where power outages are common. When choosing the right generator for your needs, it is important to keep in mind a few key factors:

  • Power rating – The power rating of a generator is determined by its wattage. Make sure to look at the watt-hour rating of your devices to see how many watts you will need for each device.
  • Fuel type – Diesel generators are extremely fuel efficient, running around one gallon per hour, but require more regular maintenance than their gas counterparts. Gasoline can be used in a pinch, but is not as efficient as diesel, and does not support as much wattage.
  • Noise level – Many generators have a decibel rating that you should consider. If your generator will be placed outside or inside your home, noise can be an important factor to keep in mind when deciding on a model.
  • Fuel capacity – For large events where the generator needs to run for an extended period of time, it is important to get a generator with high fuel capacity.
  • Portability – The primary goal of a portable generator is whether or not you can easily transport the engine. Portable generators are mostly utilized for outdoor excursions, and a simple generator is a must-have. It’s difficult to carry heavy portable diesel inverters that support big appliances alone. Lastly, if it isn’t already included, you’ll need a portable diesel generator with built-in wheels. Handles are also crucial for moving big generators around.
  • Warranty – While you should always inspect the equipment thoroughly before use, it is good to know that your warranty will cover malfunctions in the future.

Portable Diesel Generator Vs. Gasoline Generator

There are two types of portable generators: gasoline and diesel. Each has its advantages and disadvantages, but most people opt for a portable diesel generator because of the numerous benefits it offers over gasoline-powered models.

Diesel Generator

Diesel generators run on a special type of fuel called “diesel,” which is commonly used in large ships and industrial devices. It’s important to note that diesel, while similar, is not the same as regular gas. It has a higher cetane rating and requires specific parts to run efficiently. Diesel generators are extremely efficient, running on about one gallon per hour, meaning that you can keep them running for quite some time without having to refill the tank.

  • Power – Diesel engines are known for their power output, generating more watts than their gasoline counterparts.
  • Fuel economy – Diesel generators have a higher wattage output per gallon, meaning that you can keep them running for longer periods without having to refuel. This is particularly beneficial if you are planning on hosting an event where the generator will be used for many hours at a time, like for tailgating or camping.
  • Maintainability – Diesel generators require less maintenance than gasoline models, but still require regular oil changes to keep the engine running properly. They are also much quieter than gas generators, operating at about 56 decibels.
  • Vibration – Diesel engines do not vibrate nearly as much as gasoline, which is beneficial in a portable generator that you plan on using for a prolonged period of time.
  • Durability – Diesel engines are typically more durable than gasoline and will last longer when used frequently.
  • Noise – While diesel generators are much quieter than their gasoline counterparts, the noise level is still substantial (at about 56 decibels). However, if your primary concern is noise pollution, it would make sense to go with a diesel generator over a gas model. They also operate at less than half the frequency of gasoline models (which can be irritating to the human ear).

Gasoline Generator

Gasoline generators run on regular unleaded fuel and come in smaller and lighter models, perfect for indoor and close-range use like tailgating or camping where sound levels aren’t a major factor.

  • Noise – Gasoline generators typically produce about 65 decibels of noise, which is not ideal for indoor use but works fine outdoors. They are also much lighter than diesel models (at around 35 pounds), and can be carried with one hand. They do not require oil changes like diesel models either!
  • Fuel capacity – The lower wattage output per gallon means that gasoline generators will need to be refueled more often than their diesel counterparts, which makes them less efficient when used for long periods of time at an event or on the road. That being said, if you are using your generator for short periods of time only, then refilling gas tanks would not be an inconvenience.
  • Power output – Gasoline generators produce less wattage than their diesel counterparts, making them better suited to small jobs like tailgating or camping. You should not use gasoline models to power major appliances in your house for an extended period of time, but they are ideal for powering necessities like lights and TVs.
  • Durability – Gasoline engines tend to wear out faster than diesel models if used frequently. This is because gas generators require regular oil changes to function properly. They also vibrate more than diesel generators, which will affect the user’s comfort level over prolonged periods of time.
  • Availability – Gasoline generator parts are harder to come by than those designed for diesel products, so it may be difficult to find replacements during peak seasons (like Christmas). If you are planning to take your generator out on the road for an extended period of time, you will want to make sure that parts are easy to replace.
