1. The principle of the Apple earphone charging case is to charge the earphone through the built-in battery. 2. There is a small battery inside the charging case, and when the headset is placed in the charging case, the battery will automatically start charging the headset.
The charging case is charged by connecting to an external power source or its own built-in battery, and then transfers the power to the headset. 3. The charging case is designed so that users can charge their headphones anytime, anywhere, without relying on a power outlet.
In this way, users do not have to worry about the problem of insufficient power when using the headset, and it is also convenient to carry and store the headset.
Apple's earphone charging case uses wireless charging technology and contains a battery and charging coil inside. When the headset is placed in the charging case, the coil in the charging case generates an electromagnetic field, and the coil in the headset senses the electromagnetic field and converts it into electrical energy, thus charging.
The battery in the charging case will store power, and when the headset needs to be charged, the charging case will transfer the stored power to the headset.
This wireless charging principle allows users to easily charge their headphones without using a traditional charging cable connection.
