The current war in the tech industry isn’t about megapixels anymore. It’s moved on from cameras to folding displays to AI… and now the battleground is slimness. Companies like Samsung, Tecno, Honor, and Apple are actively locking horns here, shaving off precious millimeters off their phones to make them slimmer and sleeker, without really any strength tradeoff. The iPhone Air is a legitimately strong phone, and took over 200 lbs of pressure to break according to JerryRigEverything’s strength test. The problem, however, with a slim phone isn’t bendability or breakability… it’s battery capacity.
These slim phones end up boasting pro-grade performance, but at the cost of battery life. To be honest, nobody ever asked for ultra-slim phones – go on the streets and ask anyone and they’ll tell you day-long battery is more important than a slick gadget. The solution exists in broad daylight too – MagSafe power banks… but slap a chunky power bank on even a regular phone and it ends up looking like you’re using a massive Nokia Communicator phone. So we sifted through the internet to find the slimmest MagSafe power banks out there. These power banks are all under 10mm, which means they should attach to your phone without adding too much visual bulk. We’ve zeroed down on 11 power banks that fit this unique problem statement… I’ve added the 11th one not just because it’s technically impressive, but also I begrudgingly had to add Apple’s MagSafe Power Bank for the iPhone Air to this list (even though it literally only works with one smartphone). Here are our picks and what we love about them.
01. SnapWireless PowerPack Slim 2 (5.8mm)
You know what, shame on me for assuming that only legacy companies like Apple, LG, Samsung, Xiaomi, and Huawei have advanced battery R&D. The thinnest power bank on the market comes from a company you’d least expect. SnapWireless is known for its smartphone accessories like cases, chargers, and MagSafe wallets, but they also hold the title for selling the world’s thinnest power bank. The SnapWireless PowerPack Slim 2 may just pack 5,000mAh, but it does so in a form factor nearly as slim as the thinnest part of the iPhone Air.
The Slim 2 comes in 5 colors that match the iPhone 17’s palette (so you can get a power bank that matches your phone), and boasts a nifty matte metallic outer body that works as a heat sink, dissipating heat while your phone charges away. Snap the power bank on and it barely adds any thickness or weight to your phone (the thing weighs just 82 grams or 2.8 oz), and it gives your iPhone (or even Qi2-ready Android phone) an extra 5,000mAh, or just enough to get through a weekend.
Why We Recommend It
At 5.8mm, this thing is as thin as 7 credit cards stacked together… Snap it onto your phone and it practically blends in, considering most camera bumps are a comfortable 4-5mm thick anyway. At $45.56 on the SnapWireless website, this power bank is dirt cheap thanks to the Black Friday promo… let’s not also forget that it literally managed to beat stalwarts like Apple, Baseus, and Anker for the title of the ‘World’s Slimmest MagSafe Power Bank’.
02. Apple iPhone Air MagSafe Battery Pack (6.5mm)
Apple had a MagSafe Battery Pack that was discontinued in 2023, just 2 years after it launched. That battery pack notoriously got the nickname of ‘Camel Hump’, because of how it added this strange malignant growth to the back of the phone. Apple, however, quietly relaunched the MagSafe Battery Pack in September, as an iPhone Air exclusive. The reason? Because the iPhone Air’s battery could only pack so much power.
That being said, this $99 Battery Pack basically doubles your iPhone Air’s extra battery. The Air has a 3,149mAh battery itself, and the MagSafe Battery Pack adds an additional 3,149mAh to the phone. It does so while being just 6.5mm thick, and iFixit managed to tear it apart to reveal that the actual battery cell inside the pack was just a mere 2.72mm. The rest of the thickness can be attributed to the insulation/cover, the wireless charging coil, the MagSafe magnets, and the microcontroller that runs the battery pack along with its charging status LED.
Why We Recommend It
We don’t. Well, unless you’re one of the rare few people who splurged on the iPhone Air (apparently the Air only accounted for 3% of iPhone sales since September), this power bank really doesn’t make sense. It’s oddly shaped (and won’t mount on any other iPhone except the Air), and it also has the lowest mAh rating of any power bank in this list, making it an extremely niche product. But despite all that, a 6.5mm-thick power bank is quite the feat.
03. KUULAA Magnetic Power Bank (6.9mm)
Here’s what I love about this list – companies that most consumers wouldn’t have heard of are genuinely pushing boundaries by building well-engineered, slim devices. KUULAA’s slimmest power bank is just 1.1mm thicker than the thinnest power bank in the world. At 6.9mm, it sits third on this list, packing 5,000mAh of battery capacity, which is enough to charge most phones from 0-100 all the way through.
This power bank sports a glass back that matches most glass-back iPhones, and offers 7.5W standard MagSafe charging, but a pretty neat 20W when plugged in using the USB-C port on the bottom. At 110 grams (3.88 ounces), this thing is lighter than Apple’s own MagSafe Power Bank mentioned above, while still having nearly an extra 2,000mAh of capacity.
Why We Recommend It
What’s not to recommend? This thing’s a full $20 cheaper than Apple’s power bank. Super-strong N52 magnets hold the power bank on securely, and the thing supports dual-charging, working simultaneously as a wireless as well as a wired charger. The power bank comes in black or white, and if you want a pop of color, there are purple and pink variations too, although I’m personally a fan of subtle classic colors.
04. KUULAA MagOn Power Bank Ultra-Thin (7.2mm)
Back again on this list, KUULAA’s MagOn Power Bank sits at 7.2mm thick, making it just a fraction of a millimeter thicker than its own sibling. The specs are exactly the same – 5,000mAh on the inside, 7.5W wireless charging, 20W wired charging, and the ability to support dual charging. The difference, apart from the thickness, is its use of materials.
While the KUULAA Magnetic Power Bank had a glass-encased design, this one boasts an aluminum outer shell with a glass panel on the back (where the wireless coil is). The aluminum shell does two things – it helps dissipate heat efficiently, keeping the MagOn power bank cool, but it simultaneously also blends well with more premium Pro-grade iPhones that have muted metallic tones. The MagOn’s Titanium and Grey finishes complement the Pro-series iPhones wonderfully, making them a great pick if design matters to you.
Why We Recommend It
It might be thicker than its sibling, but it’s somehow lighter, clocking in at 104 grams or 3.67 ounces. I personally prefer the aluminum back because it visually blends in with my 15 Pro Max wonderfully well. That 0.3mm size bump is negligible, and your eyes (or even your hands) will never be able to tell the difference. The MagOn’s also priced at $76.5, making it even more affordable than its marginally slimmer sibling.
05. Baseus Picogo Ultra-Slim (7.6mm)
We’re sort of venturing into this grey area where all the power banks begin offering the same features. The Picogo Ultra-Slim comes from Baseus, known for their chargers and dongles (I swear by mine), measuring 7.6mm, tying it in with the TORRAS MiniMag which is next on the list. The one (actually two) thing/s giving the Picogo Ultra-Slim its edge remain, firstly, the fact that it’s the lighter of the two, measuring 3.8 ounces or 107.7 grams in weight… The next pro is just pure affordability.
As of this article, the Picogo Ultra-Slim is just $34.99, making it the most budget-friendly power bank on this list. That does matter to most people, and to seal the deal, Baseus also makes some pretty wild claims, like the Picogo Ultra-Slim having its own AI chip for monitoring and managing the power bank’s temperature for ‘cooler charging’. It also helps that the Picogo Ultra-Slim has an aluminum outer shell, helping dissipate heat.
Why We Recommend It
I recommend it for the sheer price. Baseus’ Black Friday discount gives this power bank an undeniable edge (apart from the one its slim design already has). It also supports pass-through charging, and has a 2-year warranty, which feels pretty compelling considering it’s double of what most companies offer.
06. TORRAS MiniMag (7.6mm)
TORRAS is an interesting company because while they make some pretty remarkable personal cooling wearables, they’re also absolute masters at casemaking. I still have (and cherish) their Ostand cases with the built-in rotating kickstand, but that’s not what this is about. Aside from neck-based phase-changing coolers and slim creator-friendly cases (and tempered glass protectors), TORRAS also owns bragging rights to the MiniMag, a 7.6mm-thin MagSafe power bank that packs 5000mAh of power in a deceptively thin form factor.
The MiniMag is the size of a playing card, and measures 0.01 inches thinner than the iPhone 17 (which clocks in at 0.31 inches). This, along with the fact that it weighs 115 grams or 4 ounces makes it a perfectly portable pack of power, phone and pocket-worthy. The limiting factor with thin power banks is usually being capped at 5,000mAh (and the MiniMag is limited by that too), but TORRAS also sells a thin 10,000mAh MagSafe power bank that’s a mere 0.5 inches thick… although that one clearly doesn’t make this list.
Why We Recommend It
It’s small, it’s light, and as of today, it’s $43.99 on TORRAS’ website thanks to Black Friday deals going live well in advance. The thing supports super-fast wired charging, making it faster than standard power banks, and the battery’s rated to last 500+ cycles, which easily gives you years of use without any signs of slowing down.
07. SAVEWO EVA MagCell (8mm)
Here’s an unexpected one – truly, because not only have I never heard of SAVEWO as a company, their 8mm-thick power bank looks nothing like any of the ones before it. The EVA (short for Evangelion) comes with an anime-inspired aesthetic, with graphics, characters, and motifs from the anime series Neon Genesis Evangelion. That outer aesthetic adds character to the otherwise fairly template-ish internals.
5,000mAh, 15W of wireless power delivery, 20W of PD3.0 thanks to the USB-C on the bottom – there’s nothing extraordinary here if you purely look at the spec sheet, but that’s a pretty scummy way to judge a design. The design is how it looks too, and the EVA MagCell definitely gets our vote in that department.
Why We Recommend It
At $40, this one feels like a good bargain. You get a power bank that’s slim and looks good enough that it won’t get lost or mixed up with your friends’ power banks any time soon. You’ve also got multiple designs to choose from, making this the only themed product in the entire series.
08. Native Union (Re)Classic MagSafe Power Bank (8.6mm)
If the EVA was the edgy one, Native Union’s (Re)Classic power bank is the classy one, sporting not a plastic or metal outer casing, but one made from faux leather for that extra oomph. You’ve got 5 very dapper colors to choose from, all echoing very pristine leather tan hues, blending in perfectly with any leather case you may put on your phone.
At 8.6mm, this isn’t the thinnest of the bunch, but it’s certainly impressive in its sleekness, and comes with a 5,000mAh internal, along with both MagSafe and Qi2 support (so that works for newer Android phones too). Each power bank gets paired with one of Native Union’s braided USB-C cables, upping the class-factor on this gizmo.
Why We Recommend It
Why rock plastic or glass when you could rock vegan leather? And this isn’t some run-of-the-mill vegan leather – Native Union designed it to be durable, and even gave it a gorgeous diamond texture that your fingers will love. At $69.99, it’s on the pricier side, but then again, you’re paying for style and substance as well as sleekness.
09. Anker Nano MagGo Power Bank (8.6mm)
About time Anker made it to the party. The company that practically pioneered an entire industry of charging accessories, Anker’s Nano MagGo barely makes the cut, tying in with Native Union’s (Re)Classic power bank at 8.6mm in thickness. I dock points for being basic looking, given that Anker’s power bank sort of looks like a mirror image of Apple’s own MagSafe power bank.
The only difference is that the Nano MagGo comes in 4 colors as opposed to Apple’s singular white. This bad-boy packs a 5,000mAh capacity too, with 15W fast wireless charging as well as fast-recharging for the battery pack itself. Anker claims it charges an iPhone 16 to 25% in just half an hour if you plug it in (delivering 20W of power), but marginally longer if you rely on the MagSafe charging protocol.
Why We Recommend It
Is it thicker than Apple’s own power bank? Yes, but it packs more capacity, works with all iPhones, and costs $54.99, which makes it cheaper than what Apple offers. I’d pick this if the only other option was Apple’s MagSafe power bank, but if you want style and substance, or even a competitive price point, there are others on this list.
10. PITAKA Aramid Fiber Magnetic Power Bank (8.8mm)
Vegan leather is nice, but Aramid fiber is infinitely cooler. Made from the same material used to make Kevlar, PITAKA’s power bank has a reputation that precedes it. Sure, it won’t deflect bullets, but that Aramid fiber weave is genuinely one of the coolest things I’ve seen on a power bank. PITAKA’s perfected the ability to weave the fibers in different patterns, creating unique designs that truly stand out. While blending in thanks to the sleek 8.8mm profile.
Sure, 8.8mm isn’t the slimmest, but if you’re trying to find a power bank that truly is a treat for the eyes, this one’s your bet. It packs 5,000mAh on the inside (a standard at this point), has MagSafe and Qi2 support, and even packs a 4 LED battery indicator that tells you exactly how much juice you’ve got remaining on the bank.
Why We Recommend It
At $69.99, it’s not your budget option, but one look at the Aramid fiber weave and you’d never think of using the word ‘budget’. This thing looks gorgeous as heck, and pairs rather well with PITAKA’s woven Aramid fiber cases too. Here’s the best part, each case comes with a magnetic array on the inside, which means the Android cases all instantly become MagSafe compatible in seconds!
[Bonus] KU XIU 2025 Solid-State Magnetic Portable Charger (9.9mm)
This otherwise-unheard-of brand gets a special mention on this list – not for just being slim, but for pioneering a technology that no company on this list has managed to so far. This KU XIU power bank features a solid-state battery, which is significantly more advanced than any of the Li-ion batteries on the competition. Solid state batteries are pretty much the holy grail of consumer-grade battery technology at this point. They’re a lot more durable than Li-ion, and unlike the latter that tend to catch fire or explode under duress, solid state batteries can literally get crucified with a nail and a hammer and they’ll still work. Don’t do that though. Just know that your battery is ridiculously durable.
It’s going to be a while before we see this tech in phones, but the fact that you’re getting them in power banks this slim (at a respectable 9.9mm) is still impressive. Go to KU XIU’s website and you’ll see someone literally hammering the power bank’s battery cell, puncturing it with nails, even clipping the corner off with pliers. The thing still works without catching fire or heating up. I’d call that mighty impressive considering it isn’t even a decade since the Samsung Galaxy Note 7 fiasco we had in 2016.
Why We Recommend It
Three words. Solid State Batteries. One more word. $49.99. You read that right, this 5,000mAh solid state power bank is literally cheaper than most of the other contenders on this list. Is it thicker? Yes, but is it also safer, more long-lasting, and quite literally the future of battery tech? Also yes.
