Abstract

A rechargeable wireless mouse includes a wireless electrical-energy-receiving circuit, a transformation circuit, a wireless transmission circuit and a control circuit. The wireless electrical-energy-receiving circuit receives an electromagnetic energy from a charging plate. The transformation circuit is electrically connected to the wireless electrical-energy-receiving circuit and transforms the electromagnetic energy into an electric potential energy. The wireless transmission circuit transmits a control signal to the charging plate. The control circuit is electrically connected to the transformation circuit and the wireless transmission circuit. The control circuit receives the electric potential energy transmitted by the transformation circuit and outputs the control signal to the charging plate according to the electric potential energy. The control signal controls the charging plate such that the charging power supplied by the charging plate and received by the rechargeable wireless mouse switches between a first charging mode and a second charging mode.
