We purchased this bounce house for my son's third birthday party. It ran easily off a regular outlet and extension cord and we used it indoors. Be sure to check your ceiling height if using it indoors. We had kids jump in rotations of 3-4 kids and no one was over the specified weight limit. It was very well made with strong material. Have used it several times since and it is still holding up one year later. Ships quick. Inflates quick. Party in a Box! :)
