Hello Helpme123marco,
Thank you for posting in the Apple Support Communities. We understand that your AirPods Pro won't charge, and we'd like to help get you pointed in the right direction.
Have you also tried charging them with another cable and outlet? We ask because sometimes the outlet or the cable is the source of the issue, rather than the AirPods themselves.
If so, and if the steps in the article, If your AirPods won’t charge, also didn't resolve the issue, we recommend contacting Apple Support for further assistance: Get Support
We hope this information is useful. Kind regards.
