Mini Fan USB Charging Ultra-Long Battery Life Aviation Grade Air Outlet 199-Speed Ultra-Quiet Wind Speed

This product is in its initial state when it leaves the factory, and the built-in lithium battery may be in sleep mode.
Before first use, please make sure to fully charge the fan (using the included or compatible USB-C charging cable to connect to a power adapter or computer USB port).
After fully charging, please completely drain the fan battery (i.e. use until the fan automatically shuts down).
Repeat the cycle of “fully charged ->fully depleted” 3-5 times.
This operation helps to fully activate the internal chemical substances of the battery, achieving the nominal optimal capacity for long battery life. There is no need to deliberately perform this operation in subsequent use.
