Buying Guide: Key Purchase Considerations
- Power needs: Assess your peak wattage requirements and running watts for essential devices. Inverter generators deliver clean power suitable for electronics, while traditional portable generators offer higher raw wattage for larger loads.
- Fuel type and availability: Dual-fuel models provide flexibility when one fuel source is scarce. Gasoline is common, but propane can be cleaner and longer-lasting in storage. Consider local fuel availability and storage safety.
- Portability and weight: Look for compact frames, wheel kits, and foldable handles if you plan to move the unit frequently or store it in a vehicle or shed.
- Safety features: CO shutdown sensors are increasingly important for enclosed spaces. Some models include remote start, low-oil alarms, and automatic shutdown for improved safety and reliability.
- RV and transfer-switch compatibility: If you anticipate home backup, ensure the unit is RV-ready and compatible with a transfer switch for seamless power transfer during outages.
- Noise level and runtime: Inverter generators typically operate quieter than standard models. Check decibel ratings and runtime at a typical load to estimate daily use.
- Maintenance and support: Consider warranty length, local service options, and ease of finding replacement parts or consumables like spark plugs and air filters.
- Environmental considerations: Choose models with emissions controls and safety certifications appropriate for your region and usage scenarios.
These criteria help compare the featured options across power needs, convenience, and safety. For users prioritizing quiet operation and sensitive electronics safety, inverter generators like the WEN and Westinghouse lines offer advantages. For higher wattage requirements and flexible fuel options, dual-fuel models provide expanded capability. Always follow manufacturer instructions for fueling, starting, and maintenance to maximize performance and safety.
