The output power is related to the supply voltage/current, the speaker impedance, and the size of the audio input. When the power supply voltage/current is sufficient, usually the power supply voltage is higher and the relative output power can be made larger. Speakers with different impedances have different output powers. Usually, the speaker impedance is smaller and the power is easier to achieve. Function switch Instructions for use: 1. Plug in the power on default Bluetooth mode 2. Bluetooth disconnected, long press the switch can switch to the audio input mode 3. Bluetooth play status, short press the switch to pause / play Package included: Package A:Amplifier Board Package B:Transparent shell Package C:Amplifier and Shell Package D:Amplifier and Shell and power
