Hi there! I understand you're having trouble with your PubuFit 9A not charging. I'm here to help you troubleshoot this issue.

Let's start by checking a few things:

1. Charger and Cable: Can you confirm if you're using the original charger and cable that came with your PubuFit 9A? Sometimes, third-party accessories may not work correctly. If you have another charger, you can try that too to see if it makes any difference.

2. Connection: Ensure that the charging cable is firmly connected to both the watch and the power source. If the cable has any visible damage such as fraying or bent connectors, that might be a problem.

3. Charging Surface: Is the watch in a stable and moderate environment? Extreme temperatures (too hot or too cold) can interfere with charging. If it's in an uncomfortable environment, try moving it to a more moderate one.

4. Watch Battery Reset: If it still doesn’t charge, you can try resetting the watch. To do this, press and hold the power button for about 10 seconds until it vibrates or turns off. After that, try placing it back on the charger.

Could you let me know how these steps go? If it hasn’t improved, we can try a few advanced troubleshooting techniques.
