How They Work

Generators usually contain two primary components: an alternator and an engine.

The alternator is turned by the engine, subsequently producing AC power that runs through the voltage regulator providing 120V or 240V, as needed.

We all use AC power at home, therefore, almost anything that is normally plugged in at your home is able to be powered with a generator.

Things To Consider

Sizing guidelines

The weight and size of your generator must always be taken into consideration.

If you want something portable and lightweight, you need to opt for a smaller type of model that you can carry on your own.

If you have a vehicle and a team of workers that can help you with moving it, you can consider something larger.

Power requirements

It’s essential to look at how much power the portable unit can produce as well as the period that it can run.

You must also have more or less an idea of what you want to use the generator for and which appliances or devices you want to use.

This is especially because you cannot exceed the output wattage the unit is designed for when running your equipment.

Energy options

Many generators use gasoline while others are powered with diesel or propane.

Diesel is generally more expensive than gasoline, but it usually burns for longer and provides more energy per gallon. However, diesel generators require more maintenance.

Safety considerations

Many manufacturers nowadays provide units that automatically shut down once dangerous carbon monoxide levels are detected.

Still, never run your generator in front of or inside your garage because there’s always a chance carbon monoxide can get trapped inside and gradually enter your home.

Generators must be operated outside, a minimum of 20 feet away from your house, and away from doors and windows. The exhaust must blow away from your home.


The price of portable generators can differ substantially, and the price point is typically affected by how much power is produced by the generator as well as its runtime.
