Westinghouse 12500 Watt Dual Fuel Backup Generator
Best for: Homeowners seeking full-house power with transfer-switch capability. This model runs on gasoline or propane for flexibility during outages and peaks at 12,500 watts. It supports multiple circuits with two GFCI 120V outlets, a 30A transfer switch receptacle, and a 50A RV-ready outlet for comprehensive home coverage. Remote electric start enhances convenience during cold starts. A digital hour meter and VFT display provide real-time voltage, frequency, and run-time data, aiding maintenance scheduling.
Why selected: It combines high power with transfer-switch readiness, making it a strong choice for larger homes or critical circuits. The propane option offers longer runtime and lower fuel volatility, important during extended outages.
Limitations: Higher power comes with greater size and weight; installation complexity increases if you don’t already have a transfer switch in place.
Westinghouse 6500 Watt Dual Fuel Backup Generator
Best for: Households needing reliable, medium-scale backup with transfer-switch readiness. Gasoline runs up to 6500 peak watts and 5300 running watts; propane provides 5800 peak and 4800 running watts. A 4.7-gallon fuel tank and fuel gauge support longer operation, and the kit includes oil, a funnel, hoses, and wheel kit for easier setup. CO sensor adds safety by monitoring air quality during operation.
Why selected: The combined fuel flexibility and ready-outlet configuration suit mid-sized homes or cabins needing steady power without the higher price tag of the largest units.
Limitations: It may be overkill for small apartments or limited outdoor spaces where noise or footprint is a concern.
WEN 4,750-Watt Dual Fuel Portable Generator
Best for: Budget-conscious buyers needing a portable, dual-fuel option for small to medium loads. This model supports 4,750 surge watts (gas) and 3,800 running watts, with propane offering slightly lower continuous output. It provides 120V/240V capability for transfer switches and emergency use, and the electric start simplifies operation with a key. Wheel kit aids mobility for garage-to-yard use.
Why selected: The WEN DF475T offers essential dual-fuel versatility and transfer-switch compatibility at a lower price point, making it a strong entry-level choice.
Limitations: Lower total wattage means it’s best for smaller homes or select circuits rather than entire-house power with heavy loads.
DuroStar DS13000MX 13,000-Watt Dual Fuel
Best for: Users needing maximum power with dual-fuel flexibility for whole-home backup or demanding job sites. It delivers up to 13,000 watts (gas) and supports propane, with remote electric start and transfer-switch readiness for seamless integration into home standby systems. CO safety features add protection in occupied spaces.
Why selected: Its high output makes it suitable for larger homes, multi-room essentials, and RV setups with heavy electrical requirements during outages.
Limitations: Higher power output implies larger size and heavier weight; not ideal for compact storage spaces or highly limited outdoor areas.
Westinghouse 4650 Peak Watt Dual Fuel Generator
Best for: Compact backup needs with RV versatility. It provides 4650 peak watts and 3600 running watts on gasoline, or 3240 running watts on propane, with a 4-gallon fuel tank and a CO sensor. It includes essential outlets: a 5–20R duplex, RV-ready TT-30R, and additional L5-30R options, all with safety covers.
Why selected: This unit balances portability with safety features like a CO sensor, making it a practical option for small homes, campers, or off-grid setups.
Limitations: Lower wattage means it’s not suitable for power-hungry appliances or entire-home coverage during heavy outages.
Buying Guide
What to consider when choosing a propane generator for home use:
- Power needs: Assess essential circuits and peak loads to determine wattage requirements. Higher wattage provides more headroom for whole-home backup, while lower wattage fits limited spaces or smaller households.
- Fuel flexibility: Dual-fuel models offer gasoline or propane support. Propane tends to store longer and burn cleaner, but availability and refill logistics differ by region.
- Safety features: Look for CO sensors, automatic shutdown on low oil, and covered outlets. These features improve safety in occupied spaces.
- Transfer-switch readiness: If you plan to power a home circuit panel, ensure the unit is transfer-switch ready and compatible with your panel type.
- Outlets and compatibility: Verify outlet types match your home or RV needs (GFCI 120V, 30A/50A outputs, RV TT-30R or L14-30R receptacles).
- Run time and fuel tank size: Larger tanks extend runtime between refuels, but also increase footprint and weight. Balance with your space constraints.
- Portability vs. permanence: Consider whether you need a portable unit or a permanently installed standby system, especially for weather-prone areas.
Frequently Asked Questions
- What does dual fuel mean in these generators?
Dual fuel means the generator can run on either gasoline or propane, offering flexibility when one fuel type is scarce or more convenient.
- Is a CO sensor necessary for home backup?
CO sensors enhance safety by detecting carbon monoxide buildup and can automatically shut down the unit if dangerous levels are detected.
- Do I need a transfer switch for whole-home power?
A transfer switch is highly recommended to safely isolate house circuits from the grid and prevent backfeeding during outages.
- How do I size a generator for my home?
Start with essential circuits (refrigerator, furnace, lighting, modem, well pump) and calculate peak loads. Choose a model with wattage above the maximum anticipated load.
- What maintenance is needed for propane generators?
Regular oil checks, air filter inspections, spark plug replacement, and fuel line inspections help maintain reliability between outages.
- Is propane better than gasoline for backup power?
Propane stores longer and burns cleaner, but availability and fuel costs vary. Many users prefer dual-fuel units for flexibility.
