For this issue, you can refer to the following methods for troubleshooting:
1. When the speaker is fully charged, the indicator will go out. You can remove the cable to turn on the speaker. Double press the Power button to check if the current battery level is 100%;
2. If the speaker cannot be turned on, it can be that the speaker power has been exhausted. Please charge for one hour and then observe whether the indicator is on. If the speaker battery is completely dead, it takes about 30 minutes to charge before the indicator comes on;
3. If the indicator is still off after charging for one hour, or the indicator is on but not fully charged, please replace the charger and charging cable and try again;
4. If the above methods are not effective, please apply to the local after-sales service center for inspection and repair.
Note:
Please try not to charge the speaker for a long time or plug it into the car charger for a long time. Long-term overcharging and unstable circuit input will affect the battery life capacity. At the same time, avoid charging in an environment with too low temperature.
