Westinghouse 12500 Watt Dual Fuel Home Backup Portable Generator
Best for large homes needing high peak power. Features a 457cc Westinghouse engine, dual fuel capability, and a 6.6 gallon tank for longer runs. Remote electric start with a key fob adds convenience, while transfer switch readiness supports seamless home integration. CO shutdown and low-oil protection enhance safety. Run time varies by fuel: up to 12 hours on gasoline and robust performance on propane. This model is well suited for households with critical circuits and a need for strong surge capacity.
homeowners preparing for extended outages or those with essential circuits requiring robust peak power. Limitations: heavier unit may require more storage and transport space.
DuroStar DS13000MX 13,000-Watt Dual Fuel Generator
Best for whole-home backup with fuel flexibility. This model delivers 13,000 watts of power and supports gasoline or propane. It’s built for large homes or remote work sites with a strong chassis and a heavy-duty 500cc engine. Notable is the CO alert safety feature that shuts down the unit if dangerous gas is detected. Choose this if you want maximum power with flexible fuel options for emergencies.
Who it’s for: buyers needing peak power and fuel choice for extended outages. Limitations: propane burn can reduce raw output vs gasoline under some loads.
Westinghouse 13500 Peak Watt Dual Fuel Home Backup
Best for larger homes that need serious surge capacity. With 13,500 peak watts and 10,500 running watts on propane, this unit supports heavy appliances and multiple circuits. It includes remote electric start, a 9.5-gallon fuel tank with gauge, and multiple outlets (including transfer switch-ready). The built-in CO shutdown and digital hour meter add safety and maintenance clarity. It’s a solid pick when reliability and endurance are priorities.
Who it’s for: households with demanding power needs. Limitations: larger footprint and higher fuel usage under heavy load.
Westinghouse 6500 Watt Dual Fuel Home Backup
Best for medium homes and RV use. This model provides a balanced 6,300–6,500 watt range on gasoline and propane, a 4.7-gallon tank, and up to 14.5 hours at lower loads. It includes multiple outlets with rubber covers for safety, plus transfer switch readiness and a CO sensor in some variants. It’s a fit for budget-conscious buyers who still want practical home backup power.
Who it’s for: homes seeking reliable, mid-range power with transfer switch capability. Limitations: lower peak watts than larger models; propane performance depends on load.
WEN 4,750-Watt Dual Fuel Portable Generator (DF475T)
Best for budget-focused backup. The WEN DF475T offers 4,750 surge watts and 3,800 running watts on gasoline, with a dual-fuel option and an electric start. It runs on a 212cc engine and supports 120V and 240V configurations, suitable for smaller loads and essential circuits during outages. It’s a practical entry point for users who need basic backup without high upfront costs.
Who it’s for: budget-minded buyers seeking portable, basic power. Limitations: less peak power and smaller fuel capacity than larger units.
Buying Guide
Fuel flexibility: Prioritize dual- or tri-fuel units if you want the option to run on propane for longer outages or natural gas when gasoline isn’t available. Consider the trade-off in peak power versus long-term run time.
Power needs: Calculate your essential circuits and total wattage to pick a generator with enough running watts and surge capacity. Larger homes benefit from higher wattage units, while smaller setups fit mid-range models.
Fuel tank and runtime: Look at tank size and run time at typical loads. Bigger tanks reduce refueling, but weight and storage become considerations for portable use.
Safety features: CO sensors, automatic shutdown on low oil, and rubber outlet covers improve safety. CO detection is especially important in poorly ventilated spaces.
Startup and operation: Remote electric start, push-button starts, and easy recoil starts affect convenience, especially during storms. Transfer switch readiness simplifies integration with a home electrical panel.
Portability and durability: If you’ll move the generator between sites, consider wheel kits, handles, and overall weight. A cast-iron or robust engine improves longevity under frequent use.
Key purchase considerations
- Fuel accessibility and storage space
- Outlets and compatibility with home circuits
- Maintenance needs and ease of service
- Noise levels and neighbor considerations
Frequently Asked Questions
- What is running watts vs peak watts? — Running watts indicate continuous power output; peak watts are the surge power available for startup loads.
- Is propane or gasoline better for home backup? — Propane lasts longer in storage and can be cleaner, but gasoline often provides higher peak power; dual-fuel units offer flexibility.
- Do I need a transfer switch? — A transfer switch simplifies safe, automatic power delivery to essential circuits during outages.
- How do I determine the right generator size? — List essential appliances and lights, total their wattage, and choose a unit with higher running watts and sufficient surge capacity plus a transfer switch if needed.
- What safety features are most important? — CO detection, low-oil shutdown, and rubber-covered outlets help prevent accidents and injuries.
- Can I run a generator indoors? — No. Generators produce deadly carbon monoxide and must be used outdoors in a well-ventilated area.
