I love MagSafe batteries and by this point, I have probably tested hundreds of them. There are plenty of great options out there with different capacities, charging speeds, built-in cables, and diagnostic displays, and there seems to be a MagSafe battery variant for any situation. But the feature I like most is thinness.
Understanding the Appeal of Slim Power
These are the best ultra slim magsafe options available today because they solve a common dilemma for mobile users. People want substantial battery capacity without the burden of excessive weight. The best ultra slim magsafe designs prioritize portability while maintaining reliable power delivery.
MagSafe batteries vary in capacity, charging speed, built-in cables, and diagnostic displays. Thinness remains the defining characteristic for many discerning users. If you prioritize a pocket-friendly profile, these options deliver without compromise.
The Thinness Factor
The feature I like most is thinness. While it is great to have 10,000 mAh in a battery, that adds too much extra bulk in most daily cases. So over the last few months, I have been on the hunt for slim MagSafe batteries that add the least amount of bulk to my iPhone.
If you want to see all of these in action, be sure to check out our video below! The market for these accessories has matured significantly, offering specialized solutions for different usage patterns.
Top Contenders in the Ultra Slim Category
These are the three best ones I have tested so far. The Kuxiu B10 is not the thinnest of the three we mention, but it is definitely the most well-rounded and possibly my favorite of the bunch.
Kuxiu B10: The Well-Rounded Specialist
The Kuxiu B10 will, of course, charge your phone via MagSafe, but it has a trick up its sleeve that I think every single MagSafe battery should implement. You get 9.1mm thin and weighs 120g Qi2 wireless charging (up to 15W) 5,000mAh battery USB-C charging (in and out, up to 20W) Dual-sided MagSafe magnets Low-current mode for smaller devices like AirPods.
The feature that stands out about this one is the dual-sided Magsafe magnets. On the portion of the battery facing away from your iPhone, they added another magnet ring so you could attach additional accessories. So if you want to add a MagSafe stand, or wallet, or pop socket, you can do that. I think it is an incredible feature. It is so simple, but useful. As I said, more brands need to make this a normal feature.
The Kuxiu B10 is on sale for $39 from Kuxiu’s website. What is nice is that it also includes a MagSafe ring holder, so you can test out the dual MagSafe design right away, even if you do not have any other accessories. This is where things get exciting from a thinness standpoint.
BMX SolidState: Pushing Thinness Limits
BMX claims to have the world’s thinnest solid-state MagSafe battery. So if thinness is your top priority, then get this one. For reference, the iPhone 17 Pro is 8.75mm thin, and this battery is 6.8mm!
Here is what you get: 6.8mm thin and weighs 120g 5,000mAh Qi2 wireless charging (up to 15W) USB-C with up to 20W wired output Brushed titanium enclosure Solid-state battery tech. At just 6.8mm thin, it is noticeably slimmer than anything else in this category, even compared to already thin options.
Even though it weighs the same as Kuxiu’s B10, it feels lighter because it is so thin. It is even thinner than Apple’s MagSafe battery for the iPhone Air. The Apple version is 7.7mm thick, and the SolidSafe is 6.8mm. So if you are looking for the slimmest possible battery, this is the way to go.
It comes in three colors: Black, Silver, and Gold. You can get it for $59 on BMX’s site, and they offer discounts if you get more than 1. I actually have three of them that I always keep charged when on the go. I am a huge fan of Pitaka cases. I have used them since the iPhone X. They are ultra-thin and made with aramid fiber, which gives you an awesome look and feel. They brought that design language and thinness to the latest MagSafe power bank. This is the most balanced of the bunch.
Pitaka MagSafe: Design and Material Excellence
This is easily one of the best-feeling MagSafe batteries I have used. The aramid fiber finish adds grip while still feeling smooth and premium. It is thin enough to still feel comfortable in your pocket without it feeling too big. This one is technically the lightest of the three.
It is currently on sale on Pitaka’s site for $69 and comes in a multitude of colors and designs. If you are looking for one that balances design with thinness, and you like the woven armaid fiber look, then this is a great call as well. The craftsmanship involved in these units ensures longevity and a premium tactile experience.
Technical Specifications and Performance Insights
Understanding the underlying technology helps in making an informed choice. These power banks support Qi2 wireless charging, which represents the latest evolution in inductive power transfer. This standard enables faster charging speeds and improved efficiency compared to earlier protocols.
