Note:
1. The output power is related to the power supply voltage, speaker impedance, and sound source input size. Usually the higher the supply voltage, the higher the output power supported.
2. Speakers with different impedances can support different output power. Typically, speakers have less power and are easier to implement.
3. Components may vary slightly from batch to batch, but functional performance remains the same.
