EWORLD Handheld USB Evaporative Cooling Fan
Industrial evaporative cooling units are deployed in warehouses and outdoor stadiums. Now you can carry a rechargeable and portable evaporative cooler. It will not cool a room. But it can moisten air within 19 inches (half meter).
Do you know that fans do not actually cool the air? They move it over the surface of your skin in a manner that stimulates evaporative cooling by your own body. Evaporative coolers are a hybrid of this phenomenon. They pass warm air through a moist filter to raise relative humidity, slightly lower temperature, and perform functions of a traditional fan.
Inside the handheld unit is a custom-fit cellulose sponge. Simply soak it in water; squeeze out moisture so it is damp; snap the fully charged unit back together and turn on the switch. The sponge also acts as a filter when there are contaminants in the air like smoke. When the sponge dries out or gets dirty, remove to rinse and wring it out again. If the sponge should ever wear out, use it as a pattern to cut another household sponge as a replacement.
Recharge the internal battery with a USB cable plugged into a computer USB port, a USB-to-12 volt automobile adaptor, a USB-to-wall outlet adaptor, or USB portable charger.
