A portable generator is ideal for generating electricity when used
in places without connection to the power grid or as emergency
power-supply if the grid fails. A portable generator is ideal for
construction sites or for homeowners wanting limited electrical
power in case of an outage.

Diesel Generator

Diesel generators tend to offer better fuel economy; there is also a slight safety advantage in using diesel generators, as the fuel is safer to store and handle than gasoline. While slightly more expensive than gas generators, diesel generators are the better option when a continuous power source is needed.

Gas Generator

Gas generators are an economical choice due to both the relative low cost of gasoline versus diesel fuel as well as the comparative purchase and upkeep costs of the units themselves. Gasoline generators are the better option as an occasional, temporary backup power source.
