What to Look For

Fuel Source and Run Time

The fuel source is an important consideration for anyone new to generators.

The most common fuel sources for generators include diesel, gasoline, and propane. Diesel fuel is common for those who want to use generators for industrial applications. Also, such generators tend to be quite heavy.

For someone who wants a portable generator, then the gasoline generators are much preferred. This is because the engines can be smaller and still run efficiently.

The propane generators are not as popular as the other two types, but they can also be efficient as there is no pollution. The propane fuel source can be combined with gas so that you have a dual-fuel generator.

Power Performance

Anyone who is interested in a generator must always look at its power performance too. The last thing you want is a generator that cannot meet your electrical load needs.

The first thing you will have to do is sum up all the electronics and appliances you plan to use with the generator. From their total rated power, it is easy to know which generator would be ideal to run the electrical load.

When choosing the generator, focus more on the rated or running wattage. This gives you the power the generator will be producing as it is running.

Starting Mechanism

The starting mechanism is not a big deal for most people nowadays. This is because even the recoil mechanism is easy to use. It is not as before where you would have to pull the cord almost ten times to start the generator.

Newer generators now have a recoil mechanism that starts with the first pull. There is no doubt you will be comfortable with such a generator that is still easy to start.

To make things even simpler, generators also have an electric start. The electric start relies on a battery to start the generator.

There will be models that have both the electric and recoil mechanisms. The electric start will be the main mode of starting the generator and then the recoil is the backup in case the electric start fails.

Maintenance Needs and Build Quality

The maintenance needs of a generator can make you love or hate it. No one likes a generator that breaks down more often. Considering you might not be using it more often, it should be working great each time you have to use it.

The generator also needs to have the best build quality. This will often determine the maintenance that goes into the generator. If the workmanship is great, then the generator can work great without requiring too much maintenance.

Just make sure that you follow the maintenance schedule as given by the manufacturer. This will go a long way to ensuring that your generator keeps running smoothly.

Noise Level

The noise rating is going to be an important consideration for anyone who needs a high-performance generator that is still not noisy. It is common that sometimes you might take it camping, so you do not want to make too much noise for the other campers.

Picture a scenario where you have to run the generator overnight to power some essentials. No one wants to disturb the sleep of their neighbors. It is why you always need to get a quiet generator.

Weight and Size

The weight and size features are going to determine the portability of the generator.

If you want a portable generator, then consider one that is compact and lightweight at the same time. The manufacturer will have the dimensions and weight information in the product description. This will ensure that you can choose the right generator for portability.

Another thing that can improve portability is if the generator has wheels and handles. The wheels make it easier to push the generator around especially if it is heavy. There are some models that are lightweight that you carry them around by using their handle.
