Preface
This year, the iPhone 14 is still not equipped with a charger. Although consumers who buy nearly 10,000 yuan of mobile phones are not short of the charger's money. However, the package is equipped with a C to L cable, which is incompatible with traditional USB-A chargers. Consumers still need to purchase an additional USB-C port charger to charge.
Fortunately, the iPhone 14 series USB PD fast charging is not absent.
