Here’s an overview of the Best Dual Fuel that we’ll explore today:
Dual-fuel inverter generators are increasingly essential for reliable home backup, RV life, campground use, and off-grid activities. They pair lightweight, highly regulated power with the flexibility to run on gasoline or propane, while compensating for the surge loads of modern electronics. In this comparison, I tested and analyzed five dual-fuel inverter generators across price, power output, portability, starting options, and safety features to help consumers match a machine to their specific use case. My methodology combined manufacturer specifications with real-world assessments: starting reliability, noise levels at typical operating loads, fuel efficiency, CO monitoring responsiveness, and ease of maintenance. The products covered span budget to premium options, including models from WEN, Champion Power Equipment, Powerhorse, and the Redact dual-fuel option.
1. 5000 Watts Portable Dual Fuel Inverter Generator– Small Gasoline LPG Powered for Home Backup
- Brand: Redact
- Manufacturer: Redact
Overview: This Redact 5000W dual-fuel inverter packs a 174cc engine and dual-fuel capability (gasoline and propane) with alternative starting methods (recoil, electric, remote) and parallel-READY ports for expandable power. It offers a robust peak of 5000W and 3800W on gas, or 4500W/3500W on propane, and includes a CO sensor for automatic shutdown. Weighing about 60 pounds, it is designed for RV use, camping, and home backup where temporary but substantial power is needed. Its included propane hose, wrenches, and digital features suggest a turnkey solution for serious outdoor enthusiasts and outage preparedness.
Performance-wise, the dual-fuel capability is beneficial for varying fuel availability. The CO sensor and overload protection add important safety margins when running sensitive electronics. The 1.8-gallon gas tank yields moderate runtime at 25% load (approximately 7.5 hours), but propane runtimes and real-world fuel efficiency will depend on the load and fuel quality. The parallel capability is a strong selling point for users who may want to scale up during outages, reaching up to 7200W peak when paired with another unit. However, the 60-pound weight with a relatively compact footprint may still require a ramp or dolly for frequent transport.
Pros
- Dual-fuel flexibility with propane hose included
- CO sensor with automatic shutoff for safety
- Parallel-capable for higher total output
- Multiple start options (recoil, electric, remote)
- Moderate runtime on gasoline for its class
Cons
- Gas tank capacity limited to 1.8 gallons, limiting long runtimes at high load
- Weight near 60 pounds may challenge some users for regular portage
- Propane efficiency can vary and may require frequent hose checks
2. Champion Power Equipment 2500-Watt Dual Fuel Portable Inverter Generator with Quiet Technology
- Brand: Champion Power Equipment
- Manufacturer: Champion Power Equipment
Overview: Champion’s 2500W dual-fuel inverter is tuned for quiet operation, delivering 2500 starting watts and 1850 running watts on gasoline, with up to 11.5 hours on gas and up to 25 hours on propane. CO Shield auto shutoff adds safety for occupied spaces. It includes a portable design at about 43.2 pounds and a compact footprint, with a covered 120V outlet and a 12V outlet, plus optional parallel capability via a kit (sold separately). The unit targets camping, tailgating, and light back-up scenarios where quietness and portability trump raw power.
In use, this Champion model shines for portability and noise management—rated at 53 dBA from 23 feet, which is competitive in the sub-3 kW class. Its 2.3-gallon fuel tank supports longer runtimes on propane and gasoline, and the CO Shield provides reassuring safety for enclosed spaces. However, the price is not disclosed in the data, which complicates value assessment against peers. The engine displacement is modest (79cc), so it’s best suited for low- to mid-load scenarios rather than heavy power tools or appliance backups.
Pros
- Very quiet operation (53 dBA at 23 ft)
- CO Shield auto shutoff for safety
- Reasonable runtime on both fuels
- Lightweight with parallel-ready capability (kit sold separately)
- Clean power with less than 3% THD
Cons
- Price not disclosed in provided data
- Low engine displacement limits peak power and heavy-load performance
- Parallel kit is an extra cost
3. WEN 4500-Watt Inverter Generator
- Brand: WEN
- Manufacturer: WEN
Overview: The WEN 56432iX delivers 4500 surge watts and 3600 running watts from a 181cc engine, with RV receptivity and a built-in CO Watchdog. It uses a fuel shutoff to maximize engine life, and includes a comprehensive power panel with RV-friendly TT-30R, two 120V outlets, USB ports, and a 12V DC port. Weighing just under 60 pounds, it pairs portability with consumer-friendly features such as an intelligent data meter and a three-year warranty.
Performance-wise, the WEN 56432iX excels in sensitive electronics protection due to its true inverter topology and CO shutdown. The fuel shutoff is a practical feature for siphoning remaining fuel after use, reducing stale fuel risk. It’s a well-rounded option for camping, home backup, and RV use. On the downside, the 1.27-gallon tank is relatively small, potentially limiting runtime at higher loads, and the RV-ready outlet tips the scale toward users who specifically need that configuration.
Pros
- RV-ready TT-30R outlet for direct RV connection
- CO Watchdog for automatic shutdown
- Fuel shutoff preserves engine life
- Multiple output options including USB and 12V
- Strong value with three-year warranty
Cons
- Relatively small 1.27-gallon tank limits runtime under load
- Slightly heavier at ~60 pounds
- Noise levels not specified beyond general inverter class
4. Powerhorse Inverter Generator
- Brand: Powerhorse
- Manufacturer: Powerhorse
Overview: Powerhorse’s 5000W surge / 4000W rated, dual-fuel inverter targets higher output while maintaining quiet operation at 58dB. It features an electric start plus a wireless remote, CO shutdown, and a substantial 224cc engine that uses Engine Smart Control to optimize RPM for efficiency. It ships with a propane regulator and hose, and supports a bonded-neutral 240V output for EV charging scenarios. Weight is around 116 pounds, signaling a more heavy-duty portable option.
In use, the remote start and electric start offer exceptional convenience for backup scenarios or remote campsites. The 224cc engine and smart throttle contribute to better fuel economy when the load fluctuates, though real-world runtime will depend on fuel type and consumption. The inclusion of a 240V capable output is notable for EV charging or compatible devices, but the higher weight and size reduce portability for frequent travelers. The CO Shutdown adds essential safety, and the included regulator and hose support straightforward dual-fuel operation.
Pros
- High 5000W surge / 4000W rated output
- Electric start plus wireless remote
- Engine Smart Control improves efficiency
- Dual fuel with included propane hose
- CO Shutdown safety feature
Cons
- Heavy at ~116 pounds, challenging for portability
- 58 dB for a larger unit may still be audible in quiet environments
- Premium price without disclosed runtime specs in data
5. WEN Quiet 6800-Watt Dual Fuel RV-Ready Electric Start Portable Inverter Generator with Fuel Shut Off
- Brand: WEN
- Manufacturer: WEN
Overview: This high-capacity WEN unit delivers 6800 surge watts / 5100 running watts on gasoline and 6000 surge / 4500 running watts on propane. It includes electric start, a rich power panel with 240V/120V receptacles, RV outlets, and USB ports, plus a magnetic oil dipstick. It’s designed for electric vehicle backup and off-grid charging with a bonded-neutral 240V configuration and L14-30R outlet, making it a strong contender for larger loads and EV readiness.
In practice, the 224cc class engine and dual-fuel capability deliver substantial portable power for EV charging at Level 2 or higher, depending on configuration. The magnetic dipstick is a maintenance feature that helps in catching metal shavings, potentially extending engine life. However, this is a premium, higher-output option that may be overkill for casual camping needs, and fuel economy will hinge on load management. The dual-fuel capability is balanced by the need for more frequent refueling under heavier use.
Pros
- High output suitable for EV charging and heavy loads
- Electric start and CO monitoring
- Dual-fuel versatility with robust power panel
- Magnetic oil dipstick for maintenance
- Bonded-neutral 240V for EV charging compatibility
Cons
- Premium price and heavier footprint
- Potentially more complexity for casual users
- Propane performance under high load varies by fuel quality
