Key Features to Consider

  • Automatic CO Shutoff: Shuts down the generator if dangerous CO levels are detected.
  • Fuel Type: Gasoline, propane, or natural gas options are available. Dual-fuel models offer flexibility.
  • Electric Start: Push-button start for ease of use.
  • Fuel Efficiency: Inverters and larger models are typically more efficient.
  • Transfer Switch: Connects your generator to your home's electrical panel safely and eliminates the need for extension cords.
  • Portability: Check weight and handles for ease of movement.

Safety Tips

  • Always run portable generators at least 20 feet from your home with exhaust directed away.
  • Use generators designed with automatic CO shutoff to minimize poisoning risks.
  • Install Carbon Monoxide Detectors on every level of your home.
  • Avoid using extension cords unless necessary; opt for a transfer switch instead.

Wattage Guidelines

Estimate your power needs by calculating the wattage of essential appliances:
- Refrigerator: 600 watts
- Sump Pump: 750–1,500 watts
- Heater: 1,500 watts
- Air Conditioner: 1,000 watts
