Before we get into choosing a portable generator, let’s review exactly what a portable generator is, and what the standard uses for them are.

What is a portable generator? Typical portable generators are fueled by unleaded gasoline and have standard 120-volt power outlets like the outlets you have on the walls of your home.

What can portable generators be used for? Portable generators are extremely versatile and can be used for a wide variety of purposes. Among the most common uses of a portable generator are:

- Providing power for a home in an emergency

- Power in locations that do not have access to standard eletric outlets

- Recreational use, such as at campsites and in RVs.

How do I use a portable generator? When the generator is running, you simply plug in your tools or appliances into the 120-volt (standard) electric outlets. Some models of generators also have 240-volt outlets. 240-volt outlets are used for large appliances like clothes dryers.

Now, let’s talk about what to look for when choosing the right portable generator for you.

How high of a power capacity do I need?

Generators use two basic power measurements: peak power (sometimes referred to as startup power), and continuous power. Both kinds of power are measured in wattage.

- Peak power is the required wattage that appliances need at startup or when they are running at their highest power consumption levels.

- Continuous power is the required wattage to operate appliances under normal circumstances.

What are standby generators? Standby generators are generators that create anywhere from 5,000 to 25,000 watts of power (sometimes even more). You need to choose a generator that supplies enough peak power and continuous power for the appliances that you need to keep powered.

What are you going to use your generator for? For recreational use, A small 1,000-watt portable generator could be all you will need. If you need to power tools at a remote jobsite, you could require up to about 8,000 watts of power.

Another thing to consider is how many outlets you will need on your generator. Make sure there are enough outlets to power all of the appliances you will be using at one time.

The size of the fuel tank is another consideration and is very important. Depending on how long you will potentially need your portable generator to run, you may need a larger fuel tank. The larger the fuel tank, the longer your generator will be able to run without refueling.

Now that you know what to look for, you can compare different portable generators and find out which one will meet your needs. A good resource for your research can be found at this portable generator reference website.
