Generally charging 3-5 hours, you can charge while making the small fan need to use the power does not need to be like the home fan more, the mini fan has the function of reserve power, can do where to blow, the network will also be this as a selling point to promote the product. The mini fan can store power in addition to charging and can also use a usb port or button battery.
The portable neck-hanger fan should be charged for 12 hours the first time so as not to destroy the battery. In the future, you can use a fast charge, which can be fully charged in an hour or two.
The battery in the small fan is generally very small, and he can not withstand the voltage of the battery material for a long time. So it was about ten minutes.
3-4 hours, but I feel that a longer charge will last longer
