After Apple released the MagSafe external battery, in the actual experience, the MagSafe external battery did not have the serious fever of a third-party magnetic charging bank, but there was still fever. The MagSafe external battery is more portable to use, and there is no pressure to put it in your jeans pocket with your phone during actual use. During use, you only need to gently patch to start charging, and after use, you only need to separate the MagSafe external battery from the phone to put it in the bag.
