Abstract
A mouse pad suitable for operating with a wireless mouse is provided. The mouse pad includes a first charging circuit, a second charging circuit, a control circuit, a power supply module, a conversion circuit and a main body. The first charging circuit, the second charging circuit and the conversion circuit are each electrically connected to the control circuit, and the power supply module is electrically connected to the conversion circuit. The first charging circuit and the second charging circuit each outputs an electromagnetic energy to the wireless mouse. When the control circuit receives a load current flowing through the first charging circuit and the load current flowing through the second charging circuit, through the control circuit, a power supply current of the power supply module to the first charging circuit and to the second charging circuit are dynamically adjusted.
