The Breezie Bladeless tabletop Fan can be powered either by battery or USB connection. To use USB power, simply plug the included cord into the side of the fan. You may plug the USB end of the cord into a desktop computer, laptop, or any other USB outlet to power the fan. The Bladeless Tabletop fan also has an adjustable angle back that can be used to direct the breeze. The cooling sponge can be used to activate the Tabletop Breezie Bladeless Fan's Cool Breeze feature. Dampen the sponge with water and freeze in a shape that fits in the fan properly. Once the sponge is frozen, place it in the back of the fan. You may also apply fragrance to the cooling sponge to act as an air freshener, but it is recommended that a modest amount of fragrance is used the first time so that you can better gauge how strong you would like the scent in the future.
