Huawei nova4 can be used as a mobile power source to charge other mobile phones, because it is equipped with a certain battery capacity and supports reverse charging function. Users only need to connect another mobile phone to the Type-C interface of nova4 via USB cable, and then turn on the reverse charging function, but it should be noted that this will consume the power of nova4 and affect their own use time. In addition, in order to protect the battery life of the phone, it is recommended to use the original data cable or high-quality data cable when reverse charging.
Only Huawei phones that support wireless reverse charging can charge other phones. After the reverse charging function of the Huawei mobile phone is enabled, connect the device that supports wireless charging to the center of the back of the Huawei mobile phone (maintain steady contact). After the connection is successful, the charging device will display a message indicating that it is charging.
