Choosing the right size generator to power your needs.
When a power outage occurs or you need a power source for your home or recreational vehicle, it's essential to choose a Westinghouse portable generator that's right for your needs. A generator that's too small may not be enough, while one that's too large could waste fuel and cost more. Here's a handy guide to calculating the right power output.
Why calculate your electricity needs correctly?
A generator should be able to power all your essential appliances without overloading your system. However, there's no point in choosing an oversized model that will waste energy. Choosing the right size generator allows you to:
-
To ensure optimal and sustainable operation.
-
To save on fuel.
-
To avoid unnecessary costs.
The key: determining the total power you need.
How to calculate the total power required?
To choose the right Westinghouse generator , add together the following two power types for each appliance:
-
Operating Power : The amount of watts required to operate a device continuously.
-
Starting Wattage : The amount of additional watts required to start certain appliances, such as refrigerators or air conditioners.
Simple formula:
Operating Power + Starting Power = Total Power Required
For example :
-
Refrigerator: 700 W (operation) + 2200 W (start-up) = 2900 W.
-
Portable heater: 1500 W (operation).
-
Lights and various appliances: 500 W (operation).
Total power : 2900 W + 1500 W + 500 W = 4900 W.
To operate efficiently without overloading, choose a 5000 to 5500 W generator .

Why not use 100% of the generator capacity?
A generator should not operate at full capacity all the time. Ideally, it should not exceed 90% of its total capacity for:
-
Avoid overheating.
-
Extend the life of the device.
-
Ensure a reserve for unexpected power peaks.
Practical example: If your total needs are 4500 W, opt for a 5000 W generator.
What size generator for each situation?
-
Home and power outages : A 5000 to 9500 W generator can power essential appliances (refrigerator, heater, lights).
-
Chalet or isolated cabin : A 4000 to 6000 W dual-fuel generator offers autonomy and flexibility.
-
Recreational Vehicle (RV) : A 3000 to 4500 W inverter generator is sufficient for your electrical needs.
-
Construction sites or home : Choose a robust model of 7500 W and more to power powerful tools.
-
Camping and Outdoors : A quiet 2000-3000W inverter generator is lightweight and easy to carry.
Why choose a Westinghouse portable generator?
Westinghouse generators offer:
-
Reliable power for all your needs.
-
Optimal energy efficiency to avoid waste.
-
A rugged, portable design , ideal for home, RV or jobsite.
Conclusion
Choosing the right size portable generator is essential for powering your home or business without wasting energy. By assessing your running and starting wattage needs, you can find the perfect Westinghouse model for your needs.
