If you say the iPhone Air's new ultra-thin MagSafe battery pack and thought "that's the kind of battery I want on my iPhone," don't get too excited. According to the listing on the Apple Store, this accessory is only going to work if you buy the iPhone Air. Other iPhone's aren't invited to this show.
That's not hinted or alluded to; Apple outright states that this is a battery developed for iPhone Air that won't work with other iPhone 17 models. Or at least it won't work via MagSafe, because the battery is designed to neatly fit on the back of the iPhone Air. It's just too tall to snap onto the back of other iPhones. A limiting factor that means it probably won't be a contender for our list of best portable chargers.
