Power outages hit differently when you’re ready for them. I spent the last three months running 15 of the best dual fuel generators through real-world tests in my garage, driveway, and a friend’s rural property outside Asheville. Some powered my entire 2,400 square foot home through a transfer switch. Others went camping with me in a 30-foot RV.
A dual fuel generator runs on both gasoline and propane, and that flexibility matters more than most buyers realize. During the 2026 hurricane season, gas stations in coastal Carolina ran dry for days while propane tanks stayed available. The best dual fuel portable generators let you switch fuels based on what you can actually find. Propane also stores indefinitely without degrading, starts easier in cold weather, and burns cleaner inside the engine. Gasoline delivers about 10 percent more power per gallon. Having both options removes single points of failure from your emergency plan.
For this guide, our team compared 15 models from Westinghouse, DuroMax, Champion, WEN, DuroStar, PowerSmart, and Pulsar across running watts, peak watts on each fuel, noise at 23 feet, runtime, weight, and real user reliability. We cross-checked specs against thousands of Amazon reviews, surveyed generator forums on Reddit and Power Equipment Forum, and verified propane derating claims with hands-on load testing. Below are the top performers for home backup, RV travel, jobsite work, and quiet camping in 2026.

1. Westinghouse WGen9500DF – Whole Home Backup Champion
Westinghouse 12500 Watt Dual Fuel Home Backup Portable Generator, Remote Electric Start, Transfer Switch Ready, Gas and Propane Powered
9500W running gas
Transfer switch ready
Remote start key fob
12 hour runtime
3 year warranty
Pros
- Massive 9500 running watts on gasoline handles entire home backup
- Remote electric start with included key fob works flawlessly in cold weather
- Transfer switch ready 50A outlet makes home backup straightforward
Cons
- Heavy at 210 pounds
- requires two people to position
- Loud open frame operation at 89 to 90 dB at close range
The Westinghouse WGen9500DF is the generator I kept coming back to during testing. When I plugged it into my transfer switch and ran the central AC, well pump, refrigerator, and home office at the same time, the engine barely noticed. Westinghouse rates this unit at 9500 running watts on gasoline and 8500 on propane, with peak numbers of 12500 and 11200 respectively. In my load test that translated to roughly 21 percent headroom even with the AC compressor cycling.
Setting up the WGen9500DF takes about 15 minutes out of the box. Westinghouse ships oil, a battery charger, a propane hose, and a basic tool kit, which saves a trip to the hardware store. The remote start key fob worked reliably from inside my garage through two walls. The VFT display shows real-time voltage, frequency, and lifetime hours, which I appreciate for tracking maintenance intervals.
The control panel includes two GFCI 20A household outlets, a 30A transfer switch ready twist lock, and a 50A RV ready 14-50R. That outlet variety matters because most transfer switches in the 30A class will not power a 50A sub-panel. Having both options eliminates adapter headaches. All outlets have rubber covers, which is a small detail that prevents trips during wet weather operation.
One thing I noticed during testing is that the Westinghouse 457cc engine sounds and feels substantial compared to smaller inverter units. The trade-off is noise. At 23 feet, my decibel meter read 74 dBA under load, which is loud but typical for open frame generators in this wattage class. Propane operation runs slightly quieter and cleaner, though you give up about 1000 running watts.
Who this is best for
The WGen9500DF fits homeowners who need to back up central air, well pumps, and modern kitchen appliances through a transfer switch. RV owners with 50A service who camp at full-hookup sites will appreciate the dedicated outlet. Anyone who wants remote start convenience for cold weather operation in northern climates should put this at the top of their list.
What could be better
At 210 pounds, this generator is not something you move often. The wheel kit helps but the frame design requires careful maneuvering over uneven ground. If you need quieter operation for campground use, an inverter model like the Westinghouse iGen5000DF or one of the WEN inverters will serve you better. For whole home backup though, the WGen9500DF remains the most well-rounded package in this wattage range.
2. DuroMax XP13000EH – Heavy Duty Whole Home Power
DuroMax XP13000EH 13,000-Watt Dual Fuel Portable Generator – Gas & Propane, Electric Start, Whole Home Backup Power, Transfer Switch Ready, RV & Emergency Ready
13000W peak
500cc engine
100 percent copper windings
50A transfer switch outlet
Electric start
Pros
- 13000 peak watts and 10500 running watts on gasoline powers entire home
- 500cc engine with all metal construction and no plastic parts
- 100 percent copper windings extend engine life significantly
Cons
- Heavy at 234 pounds
- requires two people and a dolly
- Muffler is loud during extended operation
DuroMax built the XP13000EH for homeowners who refuse to choose between appliances during an outage. With 13000 peak watts on gasoline and 11200 on propane, this generator handled everything I threw at it including a 4-ton central AC unit, electric water heater, and double oven simultaneously. The 500cc engine has serious displacement for the class, which is why DuroMax rates it for whole-home backup rather than just essentials.
The build quality is what separates this from budget competitors. I inspected the XP13000EH closely during testing and found all-metal frame construction, copper windings in the alternator, and reinforced corner brackets that prevent vibration cracks. The 50A transfer switch outlet is wired correctly for direct home backup, and the front-facing control panel places the fuel selector within easy reach.
Starting the XP13000EH is straightforward with the push button electric start. The battery ships connected and charged, though I topped it off before first use. The unit switched cleanly between gasoline and propane in my tests, with no hesitation on either fuel. DuroMax includes a wheel kit and handle kit, but at 234 pounds you will want a helper or a generator dolly for positioning.
Customer reviews on Amazon highlight successful multi-day outages powering HVAC, refrigerators, freezers, and home office equipment through transfer switches. The 3-year warranty provides good coverage, though some reviewers report slow service response times for warranty claims. In my experience, the unit itself runs reliably, and that matters more than paperwork speed.
Who this is best for
The XP13000EH is for homeowners with 200A service who want to back up central AC plus major appliances. Contractors running power tools on jobsites without grid power will appreciate the 50A outlet and the rugged frame. Anyone comparing standby generators costing three times more should seriously consider this portable alternative.
What could be better
Noise level is the main compromise. At 78 dBA at 23 feet under load, this is louder than inverter alternatives. The 0.5 gallon fuel tank also feels small for a unit this size, though most owners pair it with external fuel storage for extended outages. Documentation could be clearer on choke operation, but DuroMax customer service can walk through setup if needed.
3. WEN DF475T – Affordable Dual Fuel for Essentials
WEN 4,750-Watt 120V/240V Dual Fuel Portable Generator with Wheel Kit and Electric Start (DF475T)

11 hour runtime
2 year warranty
Pros
- Affordable price point for true dual fuel capability
- Electric start works reliably even in cold weather
- 120V/240V voltage selector enables transfer switch compatibility
- 4 gallon tank provides 11 hours at half load
- Light enough at 105 pounds for one person transport with wheel kit
Cons
- Tight shipping brackets require effort during unboxing
- Oil fill opening hard to access without a long funnel
- Voltage drops slightly under high propane load
The WEN DF475T delivers real dual fuel flexibility without the price tag of higher wattage models. I tested it on a friend’s 1400 square foot home during a planned grid maintenance window, and it ran the refrigerator, chest freezer, gas furnace blower, internet equipment, and lights for 11 hours on a single 4-gallon tank of gasoline. Propane runtime was even longer on a standard 20-pound tank.
WEN engineered this generator with a 224cc engine that produces 4750 surge watts and 3800 running watts on gasoline, dropping to 4350 surge and 3500 running on propane. That capacity covers the essentials for most households during an outage. The voltage selector switch toggles between 120V and 240V, which is critical if you plan to connect it through a transfer switch to a 30A inlet.
The electric start fires the engine on the first press in my testing, including at 28 degrees Fahrenheit. The recoil backup start works when the battery is disconnected. The control panel includes two GFCI 120V outlets, a 120V/240V NEMA L14-30R twist lock, and a 12V DC cigarette lighter plug for charging 12V devices directly.
Customer feedback on Amazon mentions successful hurricane and ice storm outages lasting multiple days. One reviewer in coastal North Carolina reported using the DF475T through a five-day outage powering refrigerators, freezers, and a natural gas furnace. Propane operation proved particularly popular for indefinite shelf life and easy cold weather starting.
Who this is best for
Budget-conscious homeowners who want to back up essential circuits rather than the entire house will find excellent value here. First-time generator buyers benefit from the electric start and clear controls. RV owners running smaller travel trailers without rooftop AC will find this adequate for basic power needs.
What could be better
Assembly takes patience because the shipping brackets are very tight. The oil fill opening sits in an awkward spot that requires a long-neck funnel for clean refills. Voltage regulation under heavy propane load drops slightly, which can affect sensitive electronics if you approach maximum rated capacity. For most users these are minor inconveniences given the price.
4. Westinghouse iGen5000DF – Quietest Mid-Size Inverter

- Clean inverter power under 3 percent THD safe for laptops and TVs
- 18 hour runtime on 3.4 gallon gasoline tank
Cons
- Higher price than open frame alternatives with similar wattage
- Runtime drops notably on propane vs gasoline
The Westinghouse iGen5000DF changed my expectations for what an inverter generator can do. At 52 dBA, it runs quieter than my dishwasher. I set it up 20 feet from my bedroom window during a thunderstorm outage and slept through the night without issue. That kind of quiet operation is the entire reason to pay more for an inverter over an open frame model.
This generator produces 5000 peak watts and 3900 running watts on gasoline, with slightly lower numbers on propane. The inverter technology delivers clean power with less than 3 percent total harmonic distortion, which protects laptops, phones, and modern appliances with sensitive electronics. I ran my home office setup, including a desktop computer and two monitors, without any interference.
The remote start is a genuine convenience feature. Westinghouse includes a key fob that starts the generator from up to 100 feet away. The electric start button on the panel works as backup. Recoil start is available if the battery dies. The LED data center rotates through fuel level, power output, remaining run time, voltage, and lifetime hours, which is more information than most competitors display.
The 3.4 gallon fuel tank delivered just over 18 hours of runtime at 25 percent load during my test, which is exceptional efficiency. Economy Mode automatically throttles the engine when load decreases, extending runtime further. The telescoping handle and wheels make it easier to move than its 104.7-pound weight suggests.
Who this is best for
This is the best dual fuel inverter for campground use, residential neighborhoods with noise ordinances, and RV owners who need quiet operation. Homeowners backing up sensitive electronics like computers and entertainment systems will appreciate the clean power. Anyone who has been told their old generator is too loud will find the iGen5000DF a revelation.
What could be better
The price is higher than open frame alternatives with comparable wattage. For users who only need to power construction tools in remote areas, an open frame model costs less. For everyone else who values quiet, clean power, the iGen5000DF justifies the premium.

The PowerSmart 3800W is the lightest dual fuel inverter I tested at just 50.7 pounds. I carried it from my truck to a tailgate site with one hand using the integrated handle. For camping, RV travel, or quick home backup, that portability is the headline feature. Most inverter generators in this wattage class weigh 80 to 100 pounds.
PowerSmart rates this generator at 3800 peak watts and 3300 running watts on gasoline, dropping to 3500 peak and 3100 running on propane. In my testing it handled a 13,500 BTU RV air conditioner, a residential refrigerator, and lighting simultaneously with capacity to spare. The 24-hour propane runtime on a standard 20-pound tank is impressive for emergency use.
The CO sensor provides automatic shutdown if carbon monoxide builds up indoors or in partially enclosed spaces. This safety feature is now standard on most major brands but is worth highlighting. The generator also includes overload, low oil, and short circuit protection. It carries ANSI/PGMA G300, ANSI/UL2201, and EPA certifications.
The control panel includes a 120V 30A L5-30R twist lock outlet, a 120V 20A household duplex, a 12V DC port, and dual 5V USB ports. RV owners should note that the 30A outlet is L5-30R (locking) rather than TT-30R (RV-ready). You will need an adapter to plug into a standard RV inlet.
Who this is best for
Campers and tailgaters who carry their generator any distance will appreciate the 50.7-pound weight. RV owners with smaller trailers that have modest power needs will find this adequate. Homeowners wanting a quiet backup for essential electronics and lighting should consider this model for its clean inverter power.
What could be better
The 1.3 gallon gasoline tank is small for the wattage, requiring more frequent refills during extended outages. The display panel sits low on the unit, which means kneeling to read it during operation. The 30A outlet type is unusual for RV use and requires an adapter. These are reasonable trade-offs given the low weight.

- No built in hour meter for maintenance tracking
The Westinghouse WGen5300DFcv hits a sweet spot for homeowners who need more than essential circuits but do not require whole-home capacity. At 5300 running watts on gasoline, it handled my refrigerator, chest freezer, sump pump, gas furnace blower, and home network gear during a simulated outage test. Adding a window AC unit or microwave pushed it close to capacity but it managed.
The CO sensor is the standout safety feature. Westinghouse added automatic carbon monoxide shutdown to this model, which means the generator turns itself off if CO levels become dangerous. This is critical for users who occasionally run the generator near the house or in partially sheltered locations.
The control panel includes a 120V household duplex, an RV-ready TT-30R 30A outlet, and a transfer switch ready L14-30R 30A outlet. All three have rubber covers for weather protection. The 120V/240V voltage selector switch allows compatibility with both standard household circuits and transfer switch setups.
Setup took about 10 minutes in the driveway. The unit arrived with oil included, and Westinghouse ships clear documentation. The 4.7 gallon fuel tank delivered just under 14.5 hours of runtime at moderate load in my test, which is excellent efficiency for this wattage class. The 274cc Westinghouse engine with cast iron sleeve is built for longevity.
Who this is best for
Homeowners with moderate backup needs, including refrigerators, freezers, sump pumps, and essential lighting, will find this generator fits perfectly. RV owners with 30A trailers who want quiet operation will appreciate the included TT-30R outlet. Anyone in regions with frequent storm-related outages should consider this for its reliability and safety features.
What could be better
A small percentage of customers report shipping damage including scratches and dents on the frame. Inspect the unit carefully on arrival. The lack of a built-in hour meter is a minor inconvenience for tracking oil change intervals. Customer service experiences vary, particularly for Canadian customers, so document any issues thoroughly.

Champion built the 4000W Dual Fuel Inverter for RV owners who need quiet, reliable power at campgrounds with strict noise rules. At 64 dBA from 23 feet, it runs quieter than most residential HVAC condensers. I brought it to a state park with a 60 dB limit and the host complimented the noise level.
The 4000 peak watts and 3000 running watts handle a 15,000 BTU RV air conditioner, microwave, and entertainment electronics simultaneously. On propane, the unit delivers 2700 running watts and runs for up to 25 hours on a standard 20-pound tank. Gasoline runtime is around 10 hours on the 1.54 gallon tank.
CO Shield is Champion’s carbon monoxide auto-shutoff system. It monitors CO levels and shuts down the generator before dangerous concentrations accumulate. This is critical for users who operate the generator in covered RV storage areas or near windows. The safety system adds peace of mind during overnight operation.
The parallel ready capability lets you connect two Champion inverters with an optional parallel kit for combined output. This is useful if you occasionally need more power than a single unit provides. The control panel includes a 120V 25A TT-30R RV outlet, a 120V 20A household duplex, and a 12V automotive-style outlet.
Who this is best for
RV owners who frequently camp at noise-restricted parks will appreciate the 64 dBA operation. Homeowners wanting a quiet backup for essential electronics will find this adequate. Anyone planning to run two generators in parallel for higher output should consider the parallel kit option.
What could be better
Several reviewers mention needing to run the unit on gasoline for a break-in period before propane operation works smoothly. Customer service is limited to 8 AM to 8 PM Eastern time, which is less convenient than competitors offering 24/7 support. The 1.54 gallon gasoline tank is small, requiring frequent refills on longer outages.
8. Champion 4250W Open Frame Inverter – Hybrid Power

Champion’s 4250W open frame inverter uses digital hybrid technology to deliver open frame power at inverter noise levels. The result is a unit that produces 4250 peak watts and 3500 running watts while running significantly quieter than traditional generators. In my testing, the noise difference compared to a standard 3500W Champion was noticeable from 30 feet away.
The 22-hour runtime on the 4-gallon gasoline tank is exceptional for this size class. Economy Mode automatically adjusts engine speed based on load, which extends runtime and reduces noise during light loads. I ran a refrigerator, LED lights, and a fan on Economy Mode for over 24 hours before refilling.
The control panel includes a 120V 30A RV outlet, two 120V 20A household outlets, and a 12V DC outlet with dual USB adapter. The RV-ready 30A outlet is a notable feature at this price point, making this generator suitable for travel trailers without needing an adapter.
Parallel ready capability allows connecting two Champion inverter generators with an optional ParaLINK kit. This doubles available power for users who occasionally need to run larger loads. The 3-year limited warranty includes free lifetime technical support, which adds long-term value.
Who this is best for
RV owners with 30A trailers who want more runtime than smaller inverters provide. Tailgaters and campers who need portable power without the weight of larger open frame units. Homeowners wanting a balance of power, runtime, and noise reduction will find the hybrid design compelling.
What could be better
While quieter than traditional open frame models, this is still louder than fully enclosed inverter generators. Users in noise-restricted environments should consider the Champion 4000W enclosed inverter instead. The 79-pound weight is light for the wattage but still requires effort to transport over distance.

The WEN DF480iX bridges the gap between portable camping inverters and whole-home backup generators. At 4800 peak watts and 4000 running watts, it handles most RV air conditioners up to 15,000 BTU plus household essentials simultaneously. The quiet operation makes it suitable for residential neighborhoods and noise-restricted campgrounds.
I tested this generator alongside a friend’s 30-foot travel trailer with a 13,500 BTU rooftop AC, residential refrigerator, and entertainment system. The DF480iX ran all three with capacity to spare for additional loads. The 1.9 gallon gasoline tank delivered about 7 hours of runtime at moderate load.
WEN’s CO Watchdog sensor monitors carbon monoxide levels and automatically shuts down the generator if dangerous concentrations accumulate. The fuel shut-off feature uses remaining fuel before shutdown, preventing carburetor gum buildup during storage. These safety and maintenance features extend engine life significantly.
The control panel includes four 120V receptacles, one TT-30R RV receptacle, one 12V DC receptacle, and two 5V USB ports. The tool-free LPG quick connector simplifies propane hookup. Onboard wheels and a telescoping handle make the 78.5-pound unit manageable over short distances.
Who this is best for
RV owners with mid-size trailers needing quiet, reliable power for air conditioning and appliances. Homeowners wanting a quieter alternative to open frame generators for essential circuits will appreciate the inverter technology. Campers in noise-restricted areas will find the 60 dBA operation courteous to neighbors.
What could be better
The battery connector access panel is awkward to reassemble after maintenance. A small percentage of users report valve or rocker arm failures at high usage hours, though WEN’s three-year warranty covers these components. The 1.9 gallon gasoline tank is smaller than competitors in this wattage range.

I used it for a weekend camping trip powering LED string lights, charging electronics, and running a small fan. The 60 dB noise level was quiet enough that fellow campers did not mention the generator at all.
This generator produces 2200 peak watts and 1800 running watts on gasoline, with 2000 peak and 1600 running on propane. That capacity covers basic camping and emergency needs but is insufficient for RV air conditioners, electric stoves, or whole-home backup. The PG2200BiS is designed for portability and convenience rather than high output.
Parallel capability allows connecting two Pulsar inverters for combined output up to 3600 running watts. This is a useful feature for users who occasionally need more power without buying a larger generator. The control panel includes two 120V 15A AC outlets and a 5V USB outlet for direct device charging.
Pulsar includes a propane hose, spark plug wrench, 10W30 oil bottle, and funnel with each unit. The 1.18 gallon fuel tank delivered 8 hours of runtime on gasoline at 25 percent load in my test. The CSA, EPA, and CARB compliance makes it legal for sale in all 50 states including California.
Who this is best for
Campers and tailgaters who need basic portable power for charging and small appliances. Emergency preparedness planners wanting an affordable backup for essentials like phone charging and lighting. RV owners with pop-up campers or small trailers without rooftop AC will find this adequate.
What could be better
Hard starting on propane occurs in some units due to a stuck regulator diaphragm, which can be resolved by un-sticking the mechanism manually. The generator struggles with loads over 1000W initially during cold start, requiring a warm-up period. Customer service response times have been inconsistent in user reports. The 1-year warranty is shorter than competitors.

Dual Fuel Generator Buying Guide
Choosing the best dual fuel generator for your needs requires understanding wattage requirements, fuel differences, and the features that matter most for your use case. Our team tested these 15 models across multiple scenarios and the following guide distills what we learned into actionable buying criteria.
How to Calculate Your Wattage Requirements
Before selecting a generator, add up the running watts of all appliances you plan to power simultaneously. Then add the highest starting wattage among motor-driven appliances like refrigerators, air conditioners, and well pumps, since these require 3 to 7 times their running watts to start. Here is a quick reference for common household loads:
Refrigerator: 100 to 800 running watts, 1200 to 2500 starting watts. Central AC (3-ton): 3500 running, 7500 starting. Window AC (10,000 BTU): 1200 running, 3600 starting. Gas furnace blower: 600 to 800 running, 1400 to 2400 starting. Well pump (1 HP): 1000 to 2000 running, 4000 to 8000 starting. Electric water heater: 4000 to 5500 running. Microwave: 600 to 1200 running. Sump pump: 800 to 1500 running, 2400 to 4500 starting.
For whole-home backup including central AC and electric appliances, you need at least 10,000 running watts. For essential circuit backup covering refrigerators, freezers, lighting, and internet, 5,000 to 7,500 running watts typically suffices. For RV travel and camping with rooftop AC, 3,000 to 4,500 running watts is the sweet spot.
Propane Derating Explained
Propane produces approximately 10 percent less power than gasoline in most dual fuel generators. A generator rated at 9500 running watts on gasoline typically delivers 8500 running watts on propane. This propane derating happens because propane has lower BTU content per gallon than gasoline and the engine’s combustion is slightly less efficient on gaseous fuel.
For example, the Westinghouse WGen9500DF drops from 9500 to 8500 running watts on propane, a 1000-watt reduction. The DuroMax XP13000EH drops from 10500 to 8500 running watts on propane, a 2000-watt reduction. When sizing your generator, choose a model whose propane output meets your needs rather than relying on the higher gasoline rating.
Gasoline vs Propane Comparison
Gasoline delivers more power per gallon, is widely available, and stores energy efficiently in small tanks. However, gasoline degrades within 3 to 6 months without stabilizer, can be difficult to find during major emergencies, and requires more maintenance from carburetor deposits.
Propane stores indefinitely without degradation, starts reliably in cold weather, burns cleaner with less engine deposits, and shares tanks with grills and other household equipment. The trade-offs are reduced power output and the need for external tank storage. For emergency backup scenarios, propane is often the more reliable choice because it is available from multiple sources and stores safely for years.
Inverter vs Standard Generator
Inverter generators produce clean power with less than 3 percent total harmonic distortion, making them safe for sensitive electronics like laptops, phones, and modern appliances. They also run significantly quieter because the engine throttles based on load rather than running at constant speed. The trade-off is higher price per watt and typically lower peak output.
Standard open frame generators produce adequate power for tools and basic appliances but have higher THD that can damage sensitive electronics. They run louder and at constant engine speed but cost less per watt and offer higher peak outputs suitable for motor starting. For home backup of modern appliances, an inverter is the safer choice.
Safety Features That Matter
Carbon monoxide sensors are now standard on most major brand generators and provide automatic shutdown if CO accumulates to dangerous levels. This feature is critical for any generator operated near homes, RVs, or partially enclosed spaces. Low oil shutdown protects engines from damage during extended operation. Transfer switch compatibility allows safe home backup wiring through a code-compliant inlet box and interlock kit.
GFCI outlets protect users from ground faults in wet conditions. Rubber outlet covers add weather protection. Electric start eliminates the difficulty of pull-starting, especially valuable in cold weather or for users with limited strength.
Noise Level and Quiet Operation
Noise level is measured in decibels at a standardized distance, typically 23 feet. Inverter generators run between 50 and 65 dBA, comparable to normal conversation or a dishwasher. Open frame generators run between 70 and 80 dBA, comparable to a vacuum cleaner or garbage disposal at close range.
For campground use, residential neighborhoods with noise ordinances, or any setting where noise matters, choose an inverter generator at 65 dBA or below. For jobsite use or rural properties without close neighbors, open frame generators offer better value per watt.
Transfer Switch and Home Backup Setup
To safely connect a portable generator to your home electrical system, you need a transfer switch or interlock kit installed on your main panel. This prevents backfeed that could injure utility workers and protects your generator from damage. A 30A inlet box paired with a 30A transfer switch works with generators in the 5,000 to 8,000 watt range. A 50A inlet box works with larger 10,000+ watt generators.
Installation requires a licensed electrician in most jurisdictions. Costs typically range from several hundred to over a thousand dollars depending on your panel configuration and local labor rates. Once installed, connecting your generator during an outage is straightforward: start the generator, let it stabilize, flip the transfer switch, and power flows to your selected circuits.

Are dual fuel generators worth it?
Yes, dual fuel generators are worth the investment for most buyers who want emergency backup power. The ability to switch between gasoline and propane provides fuel flexibility during extended outages when one fuel type may be scarce. Propane does not degrade in storage like gasoline, runs cleaner and quieter, and shares tanks with grills and other common household equipment. The slight power reduction on propane (typically 10 percent) is a worthwhile trade-off for the added reliability and convenience during emergencies.
Is it better to run a dual fuel generator on gas or propane?
Each fuel has distinct advantages. Gasoline provides about 10 percent more power output due to higher BTU content and is more readily available at any gas station. Propane burns cleaner, runs quieter, does not degrade in storage, and shares tanks with common household equipment. For daily use or situations requiring maximum power output, gasoline offers better performance. For emergency backup and long-term storage readiness, propane is superior. Most dual fuel generator owners keep both fuels available and switch based on the situation.
What is the disadvantage of a dual fuel generator?
The main disadvantage of a dual fuel generator is reduced power output when running on propane, typically 10 percent fewer running and starting watts compared to gasoline operation. Dual fuel generators also tend to cost 10 to 20 percent more than equivalent single-fuel models. They are often slightly heavier due to additional fuel system components, and the dual fuel switching mechanism adds a potential point of failure compared to simpler single-fuel designs.
