Is it harmful to charge Apple mobile phone with ordinary charging treasure?

Yes, because each mobile phone battery has its own special charger, and the charging treasure can't be only for a certain fixed model, so the charging voltage and value may be different. Long-term charging will definitely have an impact. It is best to buy a charging treasure suitable for Apple 6, which can only be charged for one hour in an emergency, as long as it can be adhered to at home.
