Abstract: A charging apparatus connectable to a telephone includes: a base (101), a supply voltage stabilizing device (102), a line coupler device (103) and a charging port (104, 105). The supply voltage stabilizing device and the line coupler device are both fixedly installed on the base; an input port of the supply voltage stabilizing circuit is connected to a supply power (110), the supply voltage stabilizing device is respectively connected to the input port of the line coupler device and the charging port through different output ports; another input port of the line coupler device is connected to a telephone line (120), an output port of the line coupler device is connected to a fixed telephone (130); the charging port comprises a USB port (104) and a charging cable (105); an electrical device is connected to the charging apparatus through a corresponding charging port. Functions for powering a fixed telephone and charging for several electrical products at the same time are integrated in the charging apparatus.
