The invention relates to the technical field of stereo equipment and provides a portable 
wireless charging stereo. The portable 
wireless charging stereo comprises a main device and an auxiliary device. The main device is provided with a first 
loudspeaker and a transmitting module, the auxiliary device is provided with a receiving module, a filtering 
processing circuit, an amplifying circuit and a second 
loudspeaker; the main device is provided with an 
induction coil and first positioning blocks, the auxiliary device is provided with an electrified coil, the 
induction coil and the electrified coil are arranged oppositely, and the main device enables the 
induction coil and the electrified coil to achieve accurate alignment by the cooperation between the first positioning blocks and the auxiliary device. The transmitting module firstly transmits a 
wireless signal, the receiving module receives the 
wireless signal, and then the 
wireless signal is transmitted to the filtering 
processing circuit for filtering 
processing and the amplifying circuit for amplification processing in sequence to enable the second 
loudspeaker to make low-pitched sound. Accordingly, the portable wireless charging stereo is good in 
sound quality and good in low-pitched sound. In addition, the main device enables the induction coil and the electrified coil to achieve accurate alignment by the cooperation between the first positioning blocks and the auxiliary device, the induced current is large, the charging effect is good, the power is large, the sound producing effect of the first loudspeaker is good, and the auditory effect is superior.
