Buying Guide: What to Look for in a Dual Fuel Generator Under $700
Power Output and Starting Watts
One of the first things to consider is how much power you actually need. Starting watts matter for appliances with motors, like refrigerators or sump pumps. For basic home backup, a generator with around 3,000 to 5,000 starting watts is often sufficient. If you want to run multiple appliances or an RV air conditioner, look for models in the 4,000 to 6,500 watt range.
Dual fuel generators typically produce slightly less power on propane compared to gasoline. Check the specs for both fuel types to ensure the generator meets your needs even when running on propane. Our list includes options from 2,300 watts up to 8,000 watts, so you can find the right balance.
Runtime and Fuel Efficiency
Runtime determines how long you can keep running during an outage. Look for generators that offer at least 8 to 10 hours of runtime at half load on a full tank of gas. Propane runtimes are often longer, but you’ll need to factor in the size of the propane tank you connect.
Inverter generators tend to be more fuel-efficient because they adjust engine speed to the load. This can extend runtime and reduce noise. If you plan to use the generator for extended periods, prioritize fuel efficiency over raw power.
Portability and Noise Level
Portability is key if you need to move the generator between home and campsite. Look for models with wheels and handles, especially if the unit weighs over 50 pounds. Some generators in our list come with wheel kits included, making transport a breeze.
Noise level is another consideration, especially for camping or neighborhoods with noise ordinances. Inverter generators are generally quieter, producing around 50 to 60 decibels, while open-frame models can be louder. Check the decibel rating to ensure it fits your environment.
Safety Features and Outlets
Safety should never be overlooked. Look for generators with CO sensors that automatically shut off the engine if carbon monoxide levels rise. This is a critical feature for home use. Also, check for overload protection and low-oil shutoff.
Having the right outlets is essential for connecting your appliances. Most dual fuel generators offer 120V household outlets, and many include a 30A RV outlet or a 240V outlet for transfer switch compatibility. Consider what you need to power and choose accordingly.

Frequently Asked Questions
What size dual fuel generator do I need for my house?
For a typical home, a generator with 3,000 to 5,000 watts can power essential appliances like a refrigerator, lights, and a sump pump. If you want to run a central AC or well pump, consider a 5,000 to 7,500 watt model. Always calculate your starting watt requirements.
Can I run a dual fuel generator on propane indefinitely?
Yes, as long as you have a sufficient propane supply, a dual fuel generator can run continuously on propane. Propane has a longer shelf life than gasoline, making it a great option for emergency preparedness. Just ensure your tank is properly connected and sized for the generator’s consumption.
Are inverter generators worth the extra cost?
Inverter generators are worth it if you need clean power for sensitive electronics like laptops or phones, or if you value quiet operation. They are also more fuel-efficient and often lighter. For basic power needs, a conventional generator may suffice, but for RV and camping use, inverters are ideal.
How do I maintain a dual fuel generator?
Regular maintenance includes checking oil levels, replacing air filters, and draining fuel when not in use. For propane, inspect hoses for leaks. Run the generator monthly for a few minutes to keep the engine lubricated. For more tips on equipment care, see our comparison of mower types and engine brand analysis.
