Key Factors to Consider Before Buying a Dual Fuel Portable Generator

Dual fuel portable generators are a good option as they offer you flexibility when choosing the type of fuel to use. However, with many types of these generators in the market, it isn't easy to decide on one without making a good comparison. As a result, this guide is based on thorough research on the market and dual generators. Always make sure you consider the below factors before buying.

  • Fuel Capacity

Although you are getting a dual fuel portable generator, the size of the fuel tank is a crucial factor to consider before buying. This is because the size of the fuel tank will determine how long you can run the generator on gasoline fuel.

Make sure that your considerations are in line with your use. When you are looking for a generator to use in events or job sites, you know that you will need one with a big tank to enable you to run it for a long time without needing a refill.

  • Power Output

The amount of power a generator produces is a factor to consider to meet your needs. It is essential to check the power output in terms of watts to avoid buying a generator that is less powerful or more powerful than your needs. Always remember that a more powerful generator will be bigger.

The best way to do this is to look at your power demands and find a generator to match those figures. For dual fuel generators, you will find an output of 1,000 watts, and others can go to as high as 12,000 watts. Also, consider how much the generator can produce on either propane or gasoline to avoid less power when using alternative fuel.

  • Noise Level

Fuel generators use engines and produce noise. However, the noise level varies from one generator to the other depending on the type of equipment used and the engine inside. When using a generator as a power source, it is not ideal to have too much noise, depending on where you are.

Make sure you read the features to identify the amount of noise a generator produces before buying. Generators with low noise levels are always the best as they do not cause noise pollution even at night.

  • Size 

Weight and size are a must consider if you want to get the best dual fuel portable generator. You do not want to get a generator that is too heavy to carry from one place to the other, and you want to use it while traveling. Also, ensure that you consider the size. Some generators have a large size which makes it difficult to store them.

When a generator weighs more than 250 pounds, it is considered too heavy.

  • Lift Hook Bar

When you get a powerful generator, there are high chances that it will be on the heavier side. As a result, ensure you consider its life bars as they come in handy when you want to move it upstairs into a car on a ladder. Such handling mechanisms are important for people looking for generators to use on the job site since you will be moving the generator often.

Also, ensure the handle system is strong enough and durable.

  • Start Mechanism

Fuel generators come with either a recoil cord or an electric start. Both mechanisms are different in use and how easy they make your work. The recoil cord is an old technology that requires one to pull a recoil cord and kick-start the generator's engine. This is a method that requires energy and is time-consuming.

The electric start mechanism is a modern and easy one to use. You have to press a switch, and the ignition switch will start the engine. For this method, the generator stator uses an internal battery with a charge.
