Abstract
The utility model relates to a wireless charging mobile power supply which comprises a power supply module. The power supply module receives mutual inductance coupling between resonance coils through transmission resonance coils which are in wireless connection and a device to be charged, so that electric power is wirelessly transmitted to the device to be charged. The output end of the power supply module is connected with the input end of an oscillator. The output end of the oscillator is connected with the input end of a power amplifier. Current which is amplified by the power amplifier transmits electric power to the device to be charged through the resonance coils. A wireless charging module is arranged in the power supply module. According to the utility model, through the oscillator, direct current of a lithium battery built in the mobile power supply is converted into alternating current; the current is amplified by the power amplifier; and the amplified current receives mutual inductance coupling between resonance coils through the transmission resonance coils which are in wireless connection and the device to be charged, so that electric power is wirelessly transmitted; and the wireless charging mobile power supply is simple in structure, is free from wire connection, and can be used as charged.
