A solid red light on the speaker means that the speaker is charging. But if the speakers start to blink red light, it indicates low power. We recommend you charge the speaker for at least 4 hours after use to fix the solution.  If still, the red light is blinking, ensure that the power cable and charging port is not faulty, or you should try with another cable or power source. Check the power adapter connection with your speaker. The power button may be faulty if the red light is still flashing. Replace it instantly.
