Buying Guide: What to Look For
Power Output and Fuel Type
Your first consideration should be matching the generator’s output to your power needs. Running watts are more important than peak watts, as this is the sustained power the unit can deliver. Calculate the total wattage of the appliances you need to run simultaneously during an outage.
Dual fuel capability (gasoline and propane) provides crucial flexibility. Propane stores indefinitely and burns cleaner, while gasoline is often more readily available. Some models, like the Westinghouse 12000 Peak Watt Tri-Fuel, add natural gas for a permanent home connection, offering the ultimate in convenience for home backup.
Noise Level and Runtime
Inverter generators are prized for their quiet operation, which is essential for neighborhood harmony and camping. Look for decibel (dBA) ratings measured at a quarter load from 23 feet. Many models here operate around 60-65 dBA, which is quieter than a normal conversation.
Runtime determines how long you can go between refueling. A larger fuel tank and an efficient Eco mode that adjusts engine speed to demand are key. Generators like the AIVOLT 11250W boast runtimes up to 19 hours, allowing for overnight power without interruption.
Safety and Outlet Configuration
Safety is non-negotiable. A carbon monoxide (CO) auto-shutoff sensor is a critical feature that monitors air quality and turns the unit off if dangerous levels are detected. This is a must-have for any home use. For more information on this vital safety tech, see our roundup of the top portable generators with CO shutdown.
Check the outlet panel for your specific needs. A 50-amp outlet is ideal for large RVs or connecting to a home transfer switch. 30-amp and standard 120V household outlets provide versatility. Ensure the unit is transfer switch ready if you plan to integrate it with your home’s electrical panel.
Starting Mechanism and Portability
Electric start with a remote key fob is a huge convenience, allowing you to start the generator from inside your home. A reliable recoil backup is also important. While these are powerful units, features like wheel kits and folding handles, as seen on the GENMAX Portable Generator, make transport and positioning much easier.
