The most popular Brand names

Cummins Onan Portable Generator

Generators are used to perform a wide variety of tasks, and we offer a variety of models to suit almost all potential users. While a camping application may require a smaller "neighbor-friendly" inverter generator, construction or fire/rescue applications may require more power that a commercial generator provides. While all of these generators are portable by definition, most models include standard or optional wheel kits for easy movement of the generator from storage to the wherever it is needed. Ask our representative which model is the best fit for your needs.

How many watts do I need?

Generators produce AC voltage, very similar to the voltage available in your home, however while your electric utility company produces sufficient power for all your electric powered devices, a portable generator is limited in power output directly related to the engine horsepower. The amount of power that a generator can produce is rated in watts.

The wattages listed below are based on estimated wattage requirements. For exact wattages, check the data plate or operator's manual of the item you wish to power.

The best match will depend on the power (wattage) requirements of your home and the available fuel types. Some appliances with electric motors (refrigeration, air conditioners), require up to 2 to 3 times the listed wattage. The generator should be 20% larger than calculated requirements. Also, additional capacity allows more circuits to be added for future use.

How much power do you need?

Generators produce AC voltage, very similar to the voltage available in your home, however while your electric utility company produces sufficient power for all your electric powered devices, a home standby generator is limited in power output directly related to the engine horsepower. The amount of power that a generator can produce is rated in watts. Rated power is less than peak power as certain components lose efficiency as they are heated from use.

To determine wattage requirements you should determine which devices need to be powered simultaneously and what are the starting requirements. The wattage chart is provided below to assist you. Remember that with simple "power management" techniques, a small generator can provide adequate power for home or recreational applications.

* These units are usually hard-wired and require a professionally installed transfer switch.
