Hi Eli,
The run time for the Flex Power 3,300 Watt Portable Inverter Generator part # FP54FR depends on the electrical load but typically it will run for 7 to 9 hours at 25% load and 5 to 6 hours around 50% load.
The actual run time varies depending on the total wattage being drawn, whether eco mode is being used, and the ambient temperature and elevation. For example, if you're running typical RV loads like converter, lights, TV, and few small appliances you can expect the generator to be toward the upper end of its runtime range. If you're running the air conditioner continuously, that will reduce the runtime significantly.
What are you wanting to power with the Flex Power generator?
