🌟 What is a USB OTG Fan?
A USB OTG fan is a portable cooling device that can be powered directly from a smartphone’s micro USB, USB-C, or Lightning port. The term OTG (On-The-Go) means your smartphone acts as a power host and can operate external USB devices such as fans, keyboards, flash drives, etc.

This type of fan is especially popular during summer because it:

Offers hands-free cooling while browsing your phone

Requires no batteries or external power supply

Is compact and portable

Consumes very little power
