Power Output: How Many Watts Do You Need?
To determine your power needs, add up the running watts of the devices you plan to run simultaneously. A 5000-watt generator can power a 13,500 BTU RV air conditioner (around 1500 running watts), a refrigerator (600-800 watts), lights, and a TV. The iGen4000DFc is better suited for smaller loads like a microwave, coffee maker, and a few lights.
Fuel Type: Propane vs. Gasoline
Propane burns cleaner, has a longer shelf life, and is easier to store than gasoline. Dual-fuel generators let you switch between fuels for flexibility. All three models run on both gas and propane, giving you options depending on availability and cost.
Portability and Storage
These generators weigh around 90-100 pounds and include telescoping handles and never-flat wheels for easy maneuvering. The iGen4000DFc is slightly lighter, making it a bit easier to lift into a truck bed or SUV. For more on portable options, see our best portable gas generators for camping.
