WEN DF360iX Dual Fuel Inverter Generator

The WEN DF360iX offers dual-fuel flexibility with gasoline (3600 surge / 2900 running watts) and propane (3500 surge / 2600 running watts). It prioritizes quiet operation, described as comparable to a normal conversation, making it well-suited for campgrounds or neighborhoods. It also delivers clean power to protect sensitive electronics like smartphones and laptops. This model includes a CO watchdog for added safety during operation and is RV-compatible for off-grid trips.
WEN DF680iX Dual Fuel Inverter Generator

The WEN DF680iX features a 224cc dual-fuel engine with gasoline (6800 surge / 5100 running watts) and propane (6000 surge / 4500 running watts). Its bonded-neutral 240V configuration enables low-power Level 2 charging for batteries and hybrids. A CO shutdown sensor protects households by automatically turning off the unit if dangerous carbon monoxide is detected, enhancing safety during prolonged use at campsites or backyards.
PowerSmart 4400-Watt Dual Fuel Inverter Generator

The PowerSmart 4400-Watt Dual Fuel model starts at 4400W surge and 3600W running, using gasoline or propane. It provides extended runtime with a 1.6-gallon tank, delivering up to about 11 hours at 25% load, which reduces refueling frequency during outages. It operates relatively quietly for a generator of this capacity, suitable for residential areas, camping, or job sites where noise is a consideration.
Champion Power Equipment 4000-Watt Dual Fuel

Champion’s 4000-Watt Dual Fuel inverter features CO Shield carbon monoxide auto shutoff, providing enhanced safety. It delivers 4000 starting watts and 3000 running watts on gasoline and 2700 running watts on propane, with run times up to 10 hours gasoline and 25 hours propane. An optional parallel kit (sold separately) lets you connect with other inverters or power stations for added power and longer operation when needed.
WEN DF280iX Dual Fuel Inverter Generator

The WEN DF280iX provides dual-fuel operation with gasoline (2800 surge / 2250 running watts) and propane (2800 surge / 2000 running watts). It offers clean power for sensitive electronics and includes a CO watchdog shutdown sensor for safety. This compact option is suitable for lightweight travel, camping, or power backups where portability is important.
Westinghouse 4000 Peak Watt Dual Fuel Inverter

The Westinghouse model delivers 4000 peak watts and 3300 running watts at under 3% total harmonic distortion. It runs on gasoline or propane, with electric remote start and a key fob, plus a TT-30R RV outlet. It includes CO sensors and a data display that shows fuel level, power output, remaining runtime, voltage, and lifetime hours. The unit is designed for campers and home use, with parallel capability for extra total power when needed.
Buying Guide
- Power needs: Match surge and running watts to anticipated loads (refrigerator, sump pump, lights, heater). Choose a unit with enough headroom for startup spikes and future needs.
- Fuel choice: Gasoline offers easy access and quick refuels; propane stores longer and handles multiple cold-starts better in cold weather. Dual-fuel design adds flexibility for outages and outdoor use.
- Runtime and tank size: Look for higher runtime at a typical load if you expect extended outages. A larger fuel tank reduces refueling stops during camping or emergencies.
- Noise level: Quieter models (generally under 70 dB at 23 feet) are preferable for residential areas and campgrounds. Consider operating distance and location when evaluating noise tolerance.
- Safety features: CO shutoff sensors, low-THD output for electronics, and automatic shutdown in dangerous conditions improve user safety and equipment protection.
- Portability and startup: Electric start, light weight, and compact designs ease transport and setup. Check for wheels, handles, and parallel capability if you plan to scale power with multiple units.
- Outlets and RV compatibility: Ensure the generator has the right outlets (TT-30R for RV use, USB ports, 120V outlets) for your devices and appliances.
- Maintenance and warranty: Review service intervals, oil changes, and warranty length. A reputable brand with solid customer support reduces long-term ownership risk.
- Safety certifications: Look for CO guards, proper labeling, and compliance with local emissions and noise regulations.
