The specs, compared
Why these made the list
We started with 25 dual fuel generators from the pool, filtering for units that run on both gasoline and propane. We shortlisted based on wattage, inverter type (which affects noise and clean power), portability, RV readiness, electric start, and the presence of CO shutoff sensors as recommended by CPSC. We did not physically test these units; the selections rest on the specifications listed by the manufacturers and safety advice from federal agencies. All prices shown are live from the store listing and may change.
Things to weigh before buying
Understand running watts vs. peak watts
Peak wattage indicates the maximum output a generator can produce for a short period, such as during motor startup. Running wattage is the continuous output the generator can sustain. When sizing, add up the running watts of all the appliances and tools you need to power simultaneously, and choose a generator with a running wattage at or above that total.
Inverter vs. portable: which is right?
Inverter generators produce cleaner electricity (lower total harmonic distortion) and typically run quieter and at lower RPMs when the load is light, making them better for sensitive electronics like laptops and smartphones. Portable generators (often called open-frame or conventional) are usually cheaper and can provide higher wattage, but they run at a constant engine speed and can be noisier and less efficient. If you need to power computers or entertainment systems, an inverter is the safer bet.
Check for CO sensors and safety features
Carbon monoxide is an odorless, colorless gas that can be fatal. The CPSC and CDC recommend never operating a portable generator indoors and keeping it at least 20 feet from windows, doors, and vents. Many modern generators include built-in CO sensors that shut off the unit when CO levels become dangerous. Look for a model with this feature, especially if you plan to use a generator in an RV or near a home. The CPSC's safety guides stress the importance of CO alarms and outdoor use.
Consider fuel availability and runtime
Dual fuel generators run on gasoline or propane. Propane has a longer shelf life and burns cleaner, but it may be less energy-dense, meaning slightly lower running watts. Check the runtime specifications for both fuel types to ensure you have enough capacity for your needs. Some models list runtime in hours at a certain load, so use those numbers to estimate how long you can keep your essentials running during an outage.
Think about portability and weight
If you plan to move your generator between locations, for camping, tailgating, or job sites, weight and wheel kit are important. Inverter models often have a more compact and lighter frame, but high-output portables can be heavy. Look at the stated weight in the specifications and decide if you can handle it. Some units offer a wheel kit or folding handles for easier transport.
Questions
What does dual fuel mean for a generator?
A dual fuel generator can run on either gasoline or propane (and sometimes natural gas). You switch between fuels using a selector valve. This provides flexibility in what you have available during an emergency. Propane has a longer shelf life and may be more accessible in some areas, while gasoline is often cheaper and more widely available. Always check the manufacturer's instructions for how to switch safely.
How many watts do I need for essential home backup?
The number of watts you need depends on the running wattage of each appliance you want to power. Common running wattages include a refrigerator at 600 to 800 watts, a sump pump at 600 to 700 watts, and a furnace fan at 750 watts. Add these figures for all essential devices to determine your total need, then select a generator whose running wattage exceeds that sum.
Is it safe to run a dual fuel generator indoors?
No. Never operate any portable generator indoors, including in garages, basements, or sheds, even if doors and windows are open. Carbon monoxide is a colorless, odorless gas that can kill you in minutes, as emphasized by the CPSC and CDC. Only use a generator outdoors, at least 20 feet away from any windows, doors, or vents, with the exhaust directed away. Install battery-operated CO alarms in your living spaces.
Can I connect a dual fuel generator to my home's electrical panel?
If a generator is marked as 'transfer switch ready' or 'fully wired for transfer switch', you can connect it to a transfer switch that isolates your home's circuits. This should be done by a licensed electrician to ensure safety and compliance with local codes. Never plug a generator directly into a wall outlet, a practice called 'backfeeding', because it can electrocute utility workers and damage equipment.
