2-in-1 micro USB OTG Fan for Smartphones
Deal Score0
The 2-in-1 micro USB Mini Fan is a cool (see what I did there) little fan that is powered via a USB connection. What makes it unique is the fact that you can plug it into a regular sized USB port on your computer, or you can slide out the micro USB connector to use the fan with your micro USB enabled smartphone or backup battery. The 2-in-1 micro USB Mini Fan comes in five different colors.
