Deal with this year's heat waves with the handheld Smart Fan. Featuring 3 different speeds, this stylish fan will keep you cool on the go. It’s easy to use – simply push the button once to activate the lowest fan speed, once again for the medium speed and a third time for the fan's full speed (pushing the button a fourth time will turn it off). Charging time for the Smart Fan will take around an hour, which will give you an estimated 90 minute use time.
