Generator Types at a Glance

Check out our Best Generators of 2025 guide for more information on how to pick the right generator size and type for your home. Whether it’s to use appliances or charge up your electronics on your next camping trip, you don’t want to over- or underpower yourself.

Portable Generators: These wheeled units typically run on gasoline and offer 10,000-14,000 watts – enough to power essential appliances but not an entire home.

Inverter Generators: Smaller, fuel-efficient models ideal for camping and RVing.

Dual Fuel Generators: Versatile options that run on two fuel types (usually propane and gasoline), providing flexibility during emergencies and sufficient power for larger appliances.

Solar and Battery Power Stations: Clean energy options with zero emissions that can safely operate indoors. Perfect for charging electronic equipment, though weather-dependent for recharging unless alternative charging methods are available.

Calculating Your Wattage Needs

When selecting a generator, determine your power requirements by calculating:

• Running watts of all devices
• Starting/surge watts for equipment with motors
• Total = Running watts + highest starting watts

For optimal performance, choose a generator rated at least 10% above your calculated needs, with ideal operation between 50-80% of capacity.

A 10,000-watt generator can typically handle essential appliances like lights, fans, and small refrigerators. For air conditioning units, larger appliances, or sump pumps, consider higher wattage options.
