Charger Lab has taken Apple’s MagSafe Battery Pack apart to take a gander at what’s inside. The teardown offers details on how the new accessory works and the jobs that each component performs.
Attaching the MagSafe Battery Pack is a snap. Its compact, intuitive design makes on-the-go charging easy. The perfectly aligned magnets keep it attached to your iPhone 12 mini, iPhone 12, iPhone 12 Pro, or iPhone 12 Pro Max — providing safe and reliable wireless charging. And it automatically charges, so there’s no need to turn it on or off. There’s no interference with your credit cards or key fobs either.
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.
MacDailyNews Note: We currently use the Anker Magnetic Wireless Portable Charger ($45.99) which comes in black and also works via MagSafe on iPhone 12 mini, iPhone 12, iPhone 12 Pro, or iPhone 12 Pro Max and charges via USB-C.
According to a tear down video, the ring of mags inside the pack move freely; they are not glued or attached in any way. Other articles have mentioned a distinct / “loud” clicking sound when the pack is attracted to the back of your phone. Must be the mags with a little wiggle room within the pack.
