Portable generators have become a crucial part of our lives, especially during power outages. These generators are ideal for powering home appliances, electronic devices, and power tools. They are also commonly used for camping and outdoor activities, where a reliable source of electricity is needed. But one common question that homeowners often ask is, “how long can a portable generator power a house?”.
The answer to this question is not straightforward. It depends on various factors like the size of the generator, the power output, and the fuel type. However, we can estimate the runtime of a portable generator based on its fuel capacity and power output.
Fuel Capacity and Runtime
The fuel capacity of a portable generator determines how long it can run on a full tank of fuel. Most portable generators use gasoline, propane, or diesel fuel. Gasoline is the most commonly used fuel, and it is readily available. However, propane and diesel are better options if you want a longer runtime.
Propane is an efficient fuel, and it burns cleaner than gasoline. It also has a longer shelf life than gasoline, making it more convenient for long-term storage. A propane-powered generator can run for 8-12 hours on a 20-pound tank, depending on the generator’s power output and the load it is carrying.
Diesel is a fuel that is commonly used in industrial generators. It is a more efficient fuel than gasoline, and it produces more power per gallon. A diesel-powered generator can run for up to 20 hours on a full tank of fuel.
Power Output and Runtime
The power output of a portable generator determines how much power it can produce. The power output is measured in watts, and it ranges from 1000 watts to 10,000 watts or more. The higher the power output, the more appliances and devices it can power.
A portable generator with a power output of 5000 watts can power essential appliances like a refrigerator, lights, and fans for up to 8-10 hours on a full tank of gasoline. However, if you want to power more appliances, then you will need a generator with a higher power output.
Tips to Increase Runtime
There are several tips that you can use to increase the runtime of your portable generator:
- Use a fuel-efficient generator
- Reduce the load on the generator by turning off appliances and devices that are not in use
- Use energy-efficient appliances
- Use extension cords that are the appropriate length, as longer cords can cause power loss
- Regularly maintain your generator by changing the oil and air filters
Conclusion
The runtime of a portable generator depends on several factors like the fuel capacity, power output, and load. However, you can estimate the runtime based on the fuel capacity and power output. It is also essential to follow the tips mentioned above to increase the generator’s runtime and lifespan.

FAQs for “How Long Can A Portable Generator Power A House?”
1. How do I determine what size generator I need to power my house?
The size of the generator you need depends on the power requirements of your home. You should calculate the total wattage of all the appliances and electronics you want to power during an outage. Then, add an extra 25% to the total to ensure you have enough power to cover any unexpected surges.
2. How long can a portable generator run continuously?
The answer depends on the size of the generator and the amount of fuel it can hold. Typically, generators can run for several hours to a day without refueling. However, it’s important to follow manufacturer guidelines and shut off the generator for routine maintenance and to prevent it from overheating.
3. Can a portable generator power my entire house?
A portable generator can power a variety of appliances and electronics in your home, but it may not be able to provide enough power to run everything at the same time. It’s important to prioritize the most essential appliances and calculate the total wattage to ensure the generator can handle the load. Consider installing a transfer switch to safely connect the generator to your home’s electrical panel.
4. How do I safely operate a portable generator?
It’s important to follow manufacturer instructions for safe operation of your portable generator. Key tips include: always run the generator outdoors in a well-ventilated area; keep it away from windows, doors, and air conditioning units; never refuel while the generator is hot or running; and properly ground the generator to avoid electrical shock. It’s also important to use heavy-duty extension cords designed for outdoor use and never plug the generator directly into a wall outlet.
