Do the fans plug into an regular power outlet?
Yes. All of our fans (and we only use proven and reliable fans. Beware of poor fans sold by others). Our fans draw 5 to 6.5 watts each and two can run off of one normal outlet. Fans do draw a few amps more at start up so one two leg air dancer installations, start one fan at a time. The power consumption is between 500 to 750 watts depending on the product and you will not notice any significant increase in electrical costs.
