As of March 2015, Target does not have any battery-operated floor fans for sale. According to the retailer's website, Target has seven different floor fans available that are all powered from an electric plug and not a battery.
Target offers several brands of floor fans, including Vornado, Honeywell, Lasko and Stadler. The Lasko 20-inch Cyclone fan comes with a remote control and has three different speeds. Target sells it for approximately $40.
The retailer Sears, however, does have portable battery-operated fans. The largest one is a 12-inch rechargeable battery fan called the Gama Sonic GS-27R that sells for approximately $70.
