Buying Guide for 2026
Running vs Starting Watts
Understanding the difference between running (rated) watts and starting (peak) watts is crucial when choosing a generator. Running watts are the continuous power the generator can supply, while starting watts are the extra power needed to start motor-driven appliances like refrigerators or air conditioners. For most 50 amp dual fuel generators, you’ll want a model with sufficient starting wattage to handle surges without tripping breakers.
When comparing models, look at both figures. A generator with 4000 peak watts and 3300 rated watts can power essentials like lights, a fridge, and a sump pump, but may struggle with larger appliances. For RV use, a 5000 peak watt model offers more headroom. Always calculate your total load and add 20-30% for starting surges to ensure reliable operation.
Fuel Type & Runtime
Dual fuel generators run on either gasoline or propane, giving you flexibility based on availability and cost. Gasoline is widely available and offers higher energy density, but propane burns cleaner and has a longer shelf life. Many users prefer propane for storage and emergency use, as it doesn’t degrade over time.
Runtime is a key factor, especially for extended outages or camping trips. Generators with larger fuel tanks can run longer between refills. For example, some models offer up to 18 hours on a 3.4 gallon gas tank at 25% load, while others may only run 7 hours on a smaller tank. Consider your typical usage scenario and choose a model that matches your runtime needs.
Noise Level
Noise is a major consideration, especially for camping or residential use. Inverter generators are generally quieter than conventional models, with noise levels as low as 52 dBA. This is comparable to a normal conversation, making them ideal for quiet environments. Look for generators with noise ratings below 60 dBA for a peaceful experience.
Some models feature eco-mode that adjusts engine speed based on load, reducing noise and fuel consumption. If you plan to use the generator in a campground or near neighbors, prioritize quiet operation. For more on quiet options, see our list of best whisper quiet generators.
Portability
Portability is important if you need to move the generator between locations. Features like telescoping handles, wheels, and compact designs make transport easier. Some models weigh under 100 pounds and include built-in handles for lifting. For RV use, a generator with a telescoping handle and wheel kit can be a lifesaver.
Consider where you’ll store and use the generator. If you have limited space, a smaller footprint is beneficial. Many dual fuel inverter generators are designed to be lightweight and easy to maneuver, making them suitable for camping, tailgating, and job sites.
Outlets & Transfer Switch
The type and number of outlets determine what you can power. Look for models with a TT-30R RV outlet (30 amp) for direct RV connection, as well as standard 120V household outlets (5-20R) and USB ports for charging devices. Some generators also include a NEMA L5-30R locking outlet for higher power transfer.
For home backup, a generator with a transfer switch compatibility is essential. This allows you to safely connect to your home’s electrical panel. Check the generator’s output and ensure it matches your transfer switch requirements. For more on RV-specific options, check out best RV generators dual fuel.
Inverter vs Conventional
Inverter generators produce clean power with less than 3% total harmonic distortion (THD), making them safe for sensitive electronics like laptops and smartphones. They are also more fuel-efficient and quieter than conventional generators. For most modern applications, an inverter generator is the better choice.
Conventional generators are typically cheaper and can produce higher power output, but they are louder and less efficient. For heavy-duty applications like powering large tools or whole-house backup, a conventional model may be sufficient. However, for RV and camping use, inverter technology is highly recommended.
