- Long-Term Value: Avoid fuel shortages during emergencies and disasters. This makes tri-fuel options significantly more reliable than single-fuel generators.
- Environmentally Friendly: Natural gas burns cleaner than gasoline and diesel, reducing your carbon footprint during extended usage.
- Increased Safety: Many of the models above include CO alert systems, transfer switch compatibility, and covered outlets, prioritizing user safety.
What to Consider Before Buying
1. Wattage Requirements
Determine the total wattage needed for your essential devices. If you need to power HVAC systems, fridges, and multiple electronics, aim for at least 14,000 watts of peak output.
2. Fuel Source Availability
Evaluate your location:
- Urban homes with natural gas lines may prefer that for convenience.
- Rural setups may rely more on propane or gasoline due to delivery access.
3. Run Time & Tank Capacity
A longer runtime reduces refueling frequency. The Westinghouse 14500 and 18000 models offer the best in this regard.
4. Portability
Even large generators should be movable. Look for built-in wheels, handles, and compact frame designs if you plan to transport them.
5. Safety Features
Prioritize carbon monoxide detection, automatic shut-off, and GFCI-protected outlets for the safest experience.
