These are the best ultra-slim MagSafe batteries you can get today

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. While it’s 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. These are the three best ones I’ve tested so far.

If you want to see all of these in action, be sure to check out our video below!

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. It 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’s 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 don’t have any other accessories.

This is where things get exciting from a thinness standpoint. BMX claims to have the world’s thinnest solid-state MagSafe battery. So if thinness is your top priority, then get this one.

Summary:

The SolidSafe battery is 6.8mm thin, weighs 120g, has a 5,000mAh capacity, Qi2 wireless charging up to 15W, USB-C with up to 20W wired output, a brushed titanium enclosure, and solid-state battery tech. It is slimmer than the iPhone 17 Pro battery and comes in three colors. It costs $59 on BMX’s site.

The Pitaka MagSafe power bank is 8.8mm thin, weighs 118g, has a 5,000mAh capacity (also available in 10,000mAh), Qi2 wireless charging up to 15W, USB-C with up to 20W wired output, and aramid fiber construction. It is comfortable in the pocket and currently priced at $69 on Pitaka’s site.

Both batteries offer a balance of thinness, lightness, and functionality for MagSafe charging on the go. When it comes to MagSafe chargers, all three of these options are perfect fits. They are sleek, charge at 15W, and seamlessly blend with your phone, making them more than just a standard charger you carry around. Personally, I have a soft spot for the Kuxiu B10 due to its innovative extra magnetic ring. However, if thinness is your top priority, the Solid Safe charger is the way to go.

It’s hard to make a wrong choice with any of these chargers. Feel free to share your thoughts. Are you a fan of slim MagSafe batteries or do you prefer larger ones that can charge multiple devices? Let’s have a discussion below!
