Apple's MagSafe Battery Pack designed for iPhone 12 models came out this week, and Charger Lab has taken one of the new accessories apart to give us a look at its inner workings.


The teardown has detailed information on how the MagSafe Battery Pack works and what each component inside does. There are two charging coils inside, shielding for heat dissipation, and a magnetic ring that allows it to attach to iPhone 12 models.

There are two batteries inside that are connected together, with the previously known 11.13 watt hour energy and 7.62 voltage. Each individual battery is 5.733Wh, based on the internal labeling.

At the back of the MagSafe Battery Pack, there's a large metal plate to help with heat dissipation. Underneath the heat shields on the front, there are all of the chips that allow the MagSafe Battery Pack to function.

Images from Charger Lab's teardown surfaced earlier this week, but this is the first time the full video has been available and it's well worth watching for those who are interested in what's inside the MagSafe Battery Pack.

The MagSafe Battery Pack can be purchased from Apple's website for $99.

Given that Apple's MagSafe Battery Pack is capable of reverse wireless charging, as that is how it is charged through iPhone's Lightning port (or through its own Lightning port without reverse charging), I hope Apple offers new firmware that would allow it to be charged through MagSafe or Qi chargers.

Time to just come up with a iPhone 13 Pro Max B, which has case that's twice as thick, with all that extra space being extra battery.

I’m not fat shaming it… just saying I won’t buy it, too thick, too expensive, a thinner one with half the capacity would have been better…. And same color as phone or at least a few complimentary colors, they missed the boat on this one….. flop city

2270mAH (iPhone 12 mini battery size) + 1460 mAH (this battery pack) = 4130mAH, it’s still smaller than a lot of the phones on the market. On the other front, 7.4mm (iPhone 12 mini thickness) + 11.3mm (this battery pack’s thickness) = 18.7mm, it’s more than double of the thickness of all of the phones on the market. What’s the point? It seems that Apple needs to have two different battery size options for each of the iPhone models.

MacRumors writes like they are addressing a special ed class. I think we know what “Teardown” means…

I'm really surprised apple didn't put a U1 chip in this. Not that anyone would use it as an AirTag substitute, but it'd be nice to be able to locate it like one when you eventually misplace it. Missed opportunity Apple! :(

Were you living in a cave? Numerous people have said already that the voltage is double in this battery pack so in terms of Wh the capacity is also double your mAh concept.

Anyway, the capacity is still very low considering the inefficiency of wireless charging.

Also, with the “smart” feature that prefers to use the external battery first and then the internal one, you’re going to attach this thing to the phone for a long time which significantly increases the bulk. I’d rather quickly give the phone 10-20% of charge by a traditional power bank and unplug/disconnect the phone and use it as usual without adding the bulk.
