USB On-The-Go(OTG) Fan allows USB devices, such as smartphones, to act as a host, allowing other USB devices, such as USB flash drives to be attached to them. Use of USB OTG allows those devices to switch back and forth between the roles of host and device. And that's how the USB OTG fans work.

This lovely item is small and portable. You can even put it in your pocket and take it anywhere. Especially in summer, this fan can help cooling the hot air when you need. Suitable for gifts as well.

Custom logo and colors are available! Welcome to contact DH for quotations of the OTG USB fan!
