Best Generac Generators Buying Guide for 2026
Running Watts vs. Starting Watts
Understanding the difference between running watts and starting watts is essential when selecting a Best Generac Generators. Running watts represent the continuous power output your generator can sustain, which determines what appliances and tools you can operate simultaneously. Starting watts (also called surge watts) are the peak power available for just a few seconds when motors first engage, allowing you to run larger equipment that requires extra initial power.
For example, a refrigerator might need 2,000 starting watts to kick on but only 600 running watts to stay operational. If you’re planning to run multiple appliances during a power outage, ensure your Best Generac Generators has enough running watts for everything you need simultaneously, plus extra starting capacity for motor-driven equipment. Most homeowners benefit from generators with at least 5,000 to 7,000 running watts for whole-home backup.
Fuel Type and Runtime Capabilities
Best Generac Generators come in several fuel varieties, each with distinct advantages. Gasoline-powered models offer simplicity and widespread availability, making them ideal for occasional use and emergencies. Dual-fuel generators (gas and propane) provide flexibility and longer storage life, since propane doesn’t degrade like gasoline. Tri-fuel options add natural gas capability, perfect for homes with existing gas lines or those seeking maximum fuel flexibility during extended outages.
Runtime at 50% load is the industry standard measurement for comparing endurance. A Best Generac Generators with 10-hour runtime at half load typically provides 5-7 hours at full capacity. For emergency backup, look for models with 8+ hour runtimes to minimize refueling during critical situations. Propane and natural gas options generally offer extended runtime compared to gasoline-only models, and they’re better for long-term storage since fuel doesn’t deteriorate.
Noise Level and Inverter Technology
Noise output matters significantly when using generators near homes, campsites, or job sites where quiet operation is preferred. Conventional generators typically produce 74-90 dB of sound, roughly equivalent to a vacuum cleaner. Inverter generators, which use advanced electronics to produce cleaner power, usually operate at 53-75 dB levels and are suitable for sensitive electronics like computers and medical devices.
If you’re camping or need to run a generator near neighbors, inverter models provide quieter operation without sacrificing power quality. However, inverter generators typically cost more and have lower wattage ratings than conventional models. For recreational use and RV power, inverter technology is worth the investment. You can learn more about different generator features on our feature comparison page.
Portability and Durability Features
Portability depends on both weight and design features. Most portable Best Generac Generators range from 50 to 225 pounds, with handles and wheels for easier transport. Lightweight inverter models (under 100 lbs) suit camping and tailgating, while heavier conventional generators (150+ lbs) are better for stationary backup power at home or job sites. Steel-tube cradles provide durability and protection in rough environments, while never-flat wheels prevent damage during transport across uneven terrain.
Consider where you’ll store and use your Best Generac Generators. If you’re moving it frequently, weight and wheel quality matter greatly. For permanent or semi-permanent installation, durability features like weather-resistant covers, GFCI outlets, and reinforced frames become more important than portability.
Outlets and Safety Technology
Modern Best Generac Generators include multiple outlet types to accommodate different devices. Standard 120V duplex outlets work for most household items, while 240V twist-lock outlets power larger appliances like air conditioners and well pumps. USB ports on some models allow direct device charging without adapters. Transfer switch readiness means your Best Generac Generators can integrate with home electrical systems for automatic backup power during outages.
Safety features like COsense carbon monoxide detection automatically shut down the generator if dangerous CO levels are detected, protecting your family during emergency use. Low-oil shutdown prevents engine damage by stopping operation when oil levels drop. Digital displays and hour meters help track maintenance intervals and operating time.

What’s the difference between inverter and conventional generators?
Inverter generators use advanced electronics to produce clean, stable power suitable for sensitive electronics like computers, phones, and medical devices. Conventional generators produce raw power but may have voltage fluctuations. Inverter models are typically quieter (53-75 dB) compared to conventional generators (74-90 dB), making them ideal for camping and residential areas. However, inverter generators usually have lower wattage ratings and higher costs than conventional models. For more details, explore our power-based generator categories.
How long can a Best Generac Generators run continuously?
Runtime depends on fuel tank capacity and load level. Most Best Generac Generators provide 8-12 hours of runtime at 50% load, which translates to 4-7 hours at full capacity. Propane and natural gas models often offer extended runtime compared to gasoline-only versions. To maximize runtime, operate your generator at partial load whenever possible, use economy mode to reduce fuel consumption, and maintain proper fuel levels. Dual-fuel and tri-fuel models provide additional flexibility for extended outages.
Are Best Generac Generators safe to use indoors?
No, gasoline-powered Best Generac Generators should never be used indoors, in basements, garages, or enclosed spaces. They produce carbon monoxide, a deadly odorless gas that can cause serious injury or death. Always operate fuel-powered generators outdoors, at least 20 feet away from windows and doors. Modern Best Generac Generators include COsense carbon monoxide detection technology that automatically shuts down the unit if dangerous CO levels are detected, providing an extra safety layer for emergency use.
Can I use a Best Generac Generators with a transfer switch?
Yes, many Best Generac Generators are transfer switch ready, meaning they can integrate with your home’s electrical system to provide automatic backup power during outages. However, a transfer switch must be professionally installed by a licensed electrician to safely connect your Best Generac Generators to your home’s main electrical panel. This prevents dangerous backfeeding of electricity to utility lines. Check product specifications to confirm transfer switch compatibility before purchasing.
