This generator is delivered with a full tank of gas. Approximate run time is 4-6 hours depending on the number of blowers. A maximum of 3 blowers is allowed on at a time. If your event has more than 3 inflatables we strongly recomend you add a second one. Or if your event will be held greater than 150ft from an eletrical source, we recomend you add a generator in order to have the inflatable set up in desired location. 

Must be rented out with inflatable rental, we do not rent out just a generator for an event.
