Choosing the Best Home Generators for Power Outages: Pro Tips
Determine Your Load: Add up the wattage of the “must-have” items (Fridge: 600W, Lights: 100W, Wi-Fi: 20W).
Pick Your Fuel: Gas generators provide unlimited runtime as long as you have fuel, while Solar/Battery stations are silent and maintenance-free.
Safety First: If buying gas, always ensure the unit has a CO Sensor for automatic shutdown.Maintenance Tip: If using gas, run your generator for 15 minutes every few months to keep the carburetor clean and the seals lubricated.
