Buying Guide: Key Purchase Considerations
- Power needs: Prefer models delivering at least 1900 running watts for most home and RV essentials; 2500 surge watts handles brief peak loads. If you plan to power a heater or larger appliance, consider higher-rated models instead.
- Portability: Look for weight around 40 pounds or less and built-in handles if you’ll transport the unit frequently.
- Noise level: For camping or neighborhood use, a unit around 50-60 dBA at 23 feet is typically comfortable; note that some units may exceed this at higher loads.
- Fuel type and runtime: Gasoline is common; ECO or fuel-saving modes extend runtime. Check tank size and expected runtime at your typical load.
- Safety features: CO sensors and auto shutoff improve safety in enclosed spaces. Parallel capability is useful for expanding power when needed.
- Power quality: Clean, stable output with low total harmonic distortion protects sensitive electronics like laptops and TVs.
- Maintenance and service: Look for reputable brands with accessible parts and documentation. Regular oil changes and air filter checks are recommended.
