Prosser divulged this information on his latest Genius Bar podcast. He says that Apple is working on a standard battery pack and another variant that supports reverse charging. Prosser derived these details about the battery pack from a source who is “not sure” whether both the model will launch or not. While he doesn’t detail what reverse charging on the battery pack means, it could presumably be the ability to charge AirPods or other Apple accessories wireless from the other outer side of the pack at the same time.
As per Prosser, Apple could just introduce one of these variants and the reverse charging model may never see the light of the day.
However, this isn’t the first time we’re hearing about these MagSafe-compatible battery packs. Even Mark Gurman of Bloomberg spoke about the magnetic battery pack attachment for wireless charging on iPhones. The report says that Apple has been developing the battery pack for over a year and some prototypes of the battery pack have a white rubber exterior. The new accessory is expected to differ from Apple’s battery add-ons for previous iPhones – it only provides additional battery life and will not serve as a full protective case.
