Apple is working on MagSafe-compatible battery packs that will be compatible with the iPhone 12 models, and leaker Jon Prosser today said on the Genius Bar podcast that one version of the battery pack will feature "reverse charging."


According to Prosser, Apple is working on two versions of the battery packs, one that's a standard version and one that's a premium version with reverse charging. Prosser does not go into detail on reverse charging, but presumably this means that the battery pack will be able to charge an iPhone 12 while also charging AirPods from the other side at the same time.

Prosser has a mixed track record when it comes to predicting Apple's plans and is not always accurate, so the reliability of this information is unclear and should be viewed with some skepticism until confirmed. Prosser claims that his source is "not sure" if Apple will release both of these battery packs or if only one will launch, so we may not see a version with reverse charging debut. Later this week, Prosser plans to release renders of the battery packs based on information from his source.

Apple's work on iPhone 12 battery packs became apparent in mid-February after the launch of the second iOS 14.5 beta. There was a mention of a mysterious "battery pack" discovered in the code by MacRumors contributor Steve Moser, and Bloomberg later confirmed that Apple is indeed working on an iPhone 12 MagSafe battery pack.

Gurman did not mention a reverse charging possibility, but some of the prototypes were described as having a white rubber exterior. Gurman said that development on the accessory has been hindered by software issues that Apple is still working on fixing before releasing the accessory.

Bilateral wireless charging was rumored for the 2019 iPhone 11 models, but it did not end up being a feature that Apple implemented because the company wasn't able to make it work. Two way wireless charging would have allowed an iPhone to charge another iPhone or to charge a small accessory like the AirPods.

Now this is honestly a great use of MagSafe. Will totally buy! (with or without the reverse charging)

Hopefully it's priced between $30 and $80, like other Apple chargers?

I think this is the whole next gen of products allowing it to work like next gen air pods could allow it to work with reverse wireless charging

I assume it would also charge the airpods if it wasn't connected to an iphone as well? If so, it's not a bad product.

There are definitely opportunities for other manufacturers to produce MagSafe charging solutions beyond the puck, stand, case or pack. Could be interesting to make removable charging pads that could be zipped into pockets of a briefcase or backpack, so you could easily magnetically connect and charge your phone while it’s in a safe place. Or maybe make an iPad case with integrated battery that you could magnetically attach your iPhone, iPods or Watch to charge them while using the iPad.

15 minutes in the future
how about making it easier to charge your watch on the go?
For some reason I remember around series 3 Apple made reference for Qi charging for the watch (presumably to allow air power to work) but it never materialized. Some people even were able to charge Apple watches on random Qi chargers with the coils in the right place.
Something definitely changed with series 3 charging because it was going to be the only model that supported AirPower.

I find it kinda funny that all those "leakers" publish their reports right after Gurman's and Kuo's. Never before.
Because they don't. Prosser is more accurate than Kuo. Gurman is in his own league. Everyone else is playing for 2nd and they have plenty of their own leaks that Mark doesn't get.

Wouldn’t the reverse charging on the battery mean using MagSafe it could be charged and then charge your device using the same surface? So you could use you MagSafe plug to charge the battery but then then when on the go use the battery to charge the phone. Or even if you still plug in your phone to charge use MagSafe to charge battery pack?
