The Ledlenser wall mount is designed for different torch models, but I don't have any specific information on whether it is directly compatible with the P7R Core. It would be advisable to consult the official Ledlenser website or customer service to make sure the mount will work with your model.
According to conrad.ch and amazon.com, the "LED Lenser 0317 Clip Intelligent" is suitable for the models P7/T7/M7/L7/B7/M7R/MT7/M8/L7-E/X7R. However, the picture on digitec does not allow to judge if it is true or not...
This charger is unfortunately not compatible with the X21R.2. For the model you requested, this accessory does not exist. Here are the accessories for the X21R.2 according to the manufacturer:
