How To Choose Which Firman Generator Is Best for You

To choose the best Firman generator for your needs, consider doing the following:

Compare Generator Type: Dual Fuel Generator or Gas Generator

First, you need to determine whether you want a dual fuel generator or a gas generator.

A dual fuel generator uses two different fuel types — usually propane and gasoline — to extend runtime. It’s a great pick for people living in remote areas and those who are always on the move because it gives you the ability to use the most suitable type of fuel according to your circumstances. Case in point: If you’re traveling in an area with no gasoline, you can run your generator on propane until you find gasoline.

In contrast, a gas generator runs on natural gas rather than conventional fuel types like propane, gasoline, or diesel. These generators are an eco-friendly alternative to dual fuel generators and provide ample power. They can do everything that dual fuel generators can, including running computers and stoves. However, you may need to pay an expert to connect your generator to the natural gas lines in your area. Keep this in mind when deciding to buy a gas generator.

Consider a Generator With an Ergonomic Handle for Moving

Most generators are extremely heavy, with many models weighing over 200 pounds. An ergonomic handle will help you to scoot the generator around, especially if your model also comes with wheels. 

Think About the Total Watts of Power You Need

Pay attention to the startup watts needed to run the equipment you want to connect to the generator. You also need to look at the running watts each appliance requires once everything’s connected. 

If you don’t get a generator with the right amount of power, you won’t be able to start and run your equipment.

For example, say your fridge only needs 600 watts to run but needs up to 2,200 watts of startup power. This means you need to get a generator that can provide at least 2,200 watts of starting power.
