- The Ozone 3K and Ozone 5K are billed as the world’s thinnest magnetic power banks
- At just 4.98mm thick, the Ozone 3K is even thinner than the iPhone Air
- Currently these power banks are on Kickstarter
While most MagSafe battery packs will work with the iPhone Air, due to its differing design to other iPhones, they won’t necessarily fit perfectly – other than the few that are designed specifically for Apple’s super slim smartphone. But even those designed for it can be a bit chunky, which isn’t ideal when the whole point of this phone is to be thin. However, a new battery pack addresses that.
Dubbed the Ozone 3K, this is just 4.98mm thick, which according to Kopplen (the company behind it) makes it the world’s thinnest magnetic power bank. While that’s not easy to verify, it’s certainly slimmer than the roughly 7.7mm thick official iPhone Air MagSafe Battery, or the similarly thick Anker Nano Power Bank. And it’s also thinner than the 5.6mm iPhone Air itself.
Of course, being so slim the Ozone 3K doesn’t have a huge capacity, with its 3,000mAh of power delivering a 62% charge to the iPhone Air, though there is also an Ozone 5K, which can give it a full charge, but comes in at a thicker 6.49mm.

Not just for the iPhone Air
And while we’re focused on the iPhone Air here, both Ozone models are also compatible with other iPhones, as well as Qi2 Android devices. In fact, if you’re using these with an Android phone you’ll get up to 15W of charging power, while on iPhones you’re limited to 7.5W.
Both battery packs are also lightweight, with the Ozone 3K coming in at 77g and the 5K at 97g, and right now they’re not overly expensive, with early bird Kickstarter pricing of just $44.99 (around £35 / AU$65), down from a standard price of $69.99 (roughly £50 / AU$105).
That pricing oddly applies to both models, so you don’t have to pay more to get a higher capacity. Though of course since these are currently on Kickstarter there’s no guarantee they’ll ever ship, so you might want to wait for retail, even though that will cost a little more.
