The plug and socket model specifications are incorrect.
Use the method of purchasing a converter to convert. If the model and specifications are correct, but it cannot be plugged in, it must be the plug or the socket. Usually the socket is deformed, so try to reshape it.
If the appearance is normal, you can try to connect. If you still cannot connect, it is recommended that you send it to a service station for testing. There is usually no problem with the charger provided. Just check the interface. Otherwise, it was misconfigured at the factory. Please contact customer service for consultation.
