Does your wireless mouse have a rechargeable lithium battery? If it is, it will not be equipped with a charging line, it should be similar to the general mobile phone charging line, plug into the interface of your mouse, and then plug in the USB port, not to charge.
General wireless mouse is the use of No. 5 or no. 7 dry battery, I use Leiber T8 wireless mouse is the use of dry battery, such a mouse you can use rechargeable battery, directly remove the battery, with a special charger, you can continue to use.
