Frequently Asked Questions

Q: Does this mini USB fan work with all Android phones?

A: This mini USB fan works with Android smartphones that have OTG (On-The-Go) functionality enabled. Most mainstream Android phones support OTG. If you're unsure whether your phone supports OTG, you can check online or in your phone's settings. Note that some brands like OPPO, VIVO, and Huawei may require you to manually enable the OTG switch in Settings before use.

Q: Can I use this USB fan with a power bank?

A: No — this fan is designed specifically for use with OTG-enabled Android smartphones only. It cannot be used with a power bank, as it requires OTG data connection, not a standard power output.

Q: Is the mini USB fan safe to use around children?

A: Yes. The fan blades are made from TPE (thermoplastic elastomer), a soft and flexible environmentally friendly material. Even if fingers accidentally come into contact with the spinning blades, the soft TPE material significantly reduces the risk of injury, making it much safer than traditional hard plastic fan blades.

Q: How loud is this USB fan during operation?

A: This fan features an ultra-quiet motor that operates with minimal noise even at its top speed of 16,000 RPM, so it won't disturb you or those around you in quiet environments like libraries, offices, or classrooms.
