About this Mini USB Cellphone Fan:

• Plugs into your smartphone.
• Inner plug is a 2-in-1 plug (Micro USB + Lightning) and the outer plug is a Type C connector.
• Immediately activates to cool you off.
• Powerful and soft blades move with quiet operation.
• Works with most newer Apple, Samsung and Android smartphone devices.
• Includes a diode which prevents voltage from being kicked back from the fan, thereby protecting the device. This is a very important safety feature some lower cost fans do not have.
• Some phone cases prevent the fan from plugging in completely, before returning the fan, remove the case and try it again.
• From research, cell phone retailers have found that most users frequently overcharge their phones. This reduces the life of the battery and/or the capacity. The fan must have a fully functional battery to operate properly.
