The Apple 12 can be charged using a power bank, but the following conditions must be met:
The power of the charging bank should support the charging demand of the Apple 12 series mobile phone. The charging power of the Apple 12 mobile phone is relatively high, and the charger supporting MagSafe magnetic charging technology or the charging bank with MagSafe function should be used.
When selecting the data cable connected to the Apple 12 phone, it is necessary to ensure that it is fully compatible with the phone and meets the relevant quality standards to avoid problems such as short circuit and can not charge the phone.
The interface of the charging bank must be compatible with the charging cable interface of the iPhone 12.
The Apple 12 series phones feature MagSafe wireless charging technology, which means they can only be charged wirelessly via MagSafe chargers. Traditional charging banks usually use USB ports to charge, and Apple 12 series phones do not directly support USB charging interfaces. Therefore, it is not possible to directly use the power bank to charge the Apple 12 phone. If you want to charge your iPhone 12, it is recommended to use the MagSafe charger or use the original Lightning cable to connect to the power adapter for wired charging.
