Assess Your Power Requirements
Start by calculating the total wattage of the appliances and devices you need to run simultaneously. Focus on the running watts, not just the peak starting watts. A generator’s running wattage must meet or exceed this total. For whole-home backup, you’ll need a high-wattage unit, while camping or tailgating may require less power. Always prioritize a unit with a buffer above your calculated needs to avoid overloading the system.
Understand Fuel Flexibility and Runtime
Dual fuel capability allows you to switch between gasoline and propane based on availability and convenience. Propane burns cleaner, produces less carbon buildup in the engine, and can be stored for much longer periods. Check the runtime specifications for each fuel type on a full tank. A longer runtime means less frequent refueling, which is critical during extended power outages or for overnight use while camping. For quiet camping power, explore our guide to Pulsar inverter generators for camping.
Prioritize Key Features and Portability
Look for features that enhance safety, convenience, and usability. A carbon monoxide auto-shutoff sensor is a vital safety addition for any home use. Electric start with a remote control offers incredible convenience, especially in poor weather. For portability, consider the unit’s weight and whether it includes wheel kits and telescoping handles. If you plan to connect to an RV, ensure the generator has a 50-amp or 30-amp outlet that matches your rig’s requirements. Our resource on Pulsar dual fuel generators for RV power delves deeper into this topic.

Alternatively, if maximum power output and tri-fuel flexibility for whole-home backup are the primary goals, the Westinghouse 14500 Peak Watt Tri-Fuel Home Backup offers exceptional capacity. We encourage you to explore all the models in our comparison to find the perfect match for your energy independence needs this 2026.
Frequently Asked Questions
What is the main advantage of a dual fuel generator?
The primary advantage is fuel flexibility and preparedness. You can use gasoline for its higher energy density and maximum power output, or switch to propane for cleaner burns, easier long-term storage, and often quieter operation. This gives you options during fuel shortages or for different types of projects.
Can I run a dual fuel generator indoors?
No, you should never run a gasoline or propane-powered generator indoors, including in garages, basements, or sheds. These engines produce deadly carbon monoxide gas that can quickly build up in enclosed spaces. Always operate generators outdoors, far from windows, doors, and vents to ensure safety.
How do I maintain a Pulsar dual fuel generator?
Regular maintenance is key to longevity. Always use fresh fuel and add a stabilizer if storing gasoline. Check and change the oil according to the manufacturer’s schedule, using the recommended type. Keep the air filter clean and inspect spark plugs periodically. For more information on specific models and care, visit our Pulsar Generators category page.
Are inverter generators better for powering electronics?
Yes, inverter generators produce clean, stable power with very low total harmonic distortion. This makes them safe for sensitive electronics like laptops, phones, and medical equipment. Traditional generators can cause power surges or fluctuations that may damage these devices, so an inverter model is the recommended choice for such applications.
