We apologize for any inconvenience this may have caused. We sincerely recommend that you follow these steps to check: 1) Check if the voltage in the region you are using the adaptor is compatible with the rated working voltage of the adaptor. 2) Check if the output voltage of the adaptor is compatible with the device's required rated working voltage. 3) Check if the adaptor interface is compatible with the charging cable interface. 4) Check if the USB cable is properly connected or if the USB cable itself is damaged. 5) Try using another adaptor to check if the problem is with the battery. 6) Check the charging ports of the device or charging cable for any dirt or damage. 7) Check the compatibility of your device's fast charging protocol with the adaptor. Some devices may use proprietary charging protocols, and cannot be charged with third-party adaptors. If the above steps do not resolve the issue, it is recommended to take the device to a service center for inspection.
