Whether you were won over by the cameras on the new iPhone 17 or you’re sticking it out with your iPhone 12, having a little extra power around is never a bad thing. The best MagSafe power bank is one that attaches firmly, charges quickly and blends in with your handset — or better yet, adds a handy stand to the mix. Right now, the fastest wireless portable chargers are Qi2 25W-certified, but so far there are only a few of those on the market (and we have our favorite). But speed isn’t everything, looks, features and price factor in as well. We’ve tested more than a dozen portable chargers to help you find the best MagSafe battery you can buy.

The best MagSafe power banks for 2025

What to consider before buying a MagSafe power bank

Choose the right capacity. Most portable MagSafe chargers have either a 5,000 milliamp hour (mAh) or 10,000mAh capacity. Obviously, the larger capacity batteries are physically bigger, but thanks to an iPhone’s magnetic attachment points, you can still use the phone comfortably as it charges. If you’re worried about overall bulk, you may prefer the slimness of a 5,000mAh battery.

Just note that a 5K battery pack won’t deliver its entire capacity to your phone due to energy loss from voltage conversion and heat dissipation. Over the years, I’ve measured around a 60-percent delivery rate for wireless banks. For example, that means an iPhone 16 with its 3,561mAh battery will get about 85 to 90 percentage points from a 5K battery. A 10K bank will charge that same phone fully once, with enough for a 50- to 60-percent boost next time.

Understand MagSafe versus Qi2. All iPhones model 12 and later have MagSafe technology, which rely on embedded magnets to align the phone with a wireless charger and can support charging speeds of up to 15 watts. The MagSafe name is owned by Apple — third-party chargers can’t freely use the term and instead call their accessories “magnetic,” or apply a branded name like Anker’s MagGo or UGreen’s MagFlow. Be sure to check the product details before buying: anything that works with Apple’s technology will be listed as MagSafe-compatible.

Qi2 is a standard from the Wireless Power Consortium (of which Apple is a member) and has the same stipulations as MagSafe (15W charging and magnetic alignment). Any company can submit their tech for this certification. iPhones 13 and later are Qi2 compatible.

The newest standard, Qi2 25W (also called Qi2.2), bumps wireless charging speeds up to 25W. The WPC says a certified smartphone using a certified charger can wirelessly go from dead to half full in about 30 minutes (keep in mind that both the charger and phone need to be certified to get those speeds) and that aligns with our testing. 

Accessories, like power banks that support the new standard are starting to hit shelves now. As for phones, Google’s Pixel 10 Pro XL, Apple’s iPhone 17, iPhone 17 Pro and Pro Max all support the standard as well. iPhone 16 models (except the 16e) support the standard after an update to iOS 26.

Remember travel restrictions. You may have seen news reports of flights being grounded because a power bank caught fire in the cabin. Currently, the TSA allows them in your carry-on luggage as long as they’re rated at 100 watt-hours or lower (about 27,000mAh for lithium ion batteries).

But some airlines have enacted further restrictions. Southwest, for example, requires you to keep power banks out of the bag and visible while charging. Even if your airline doesn’t make such demands, keeping a power brick out in the open while it’s in use is a good idea — it’ll keep it cooler and you’ll be more likely to notice if it starts to overheat. Most, if not all, MagSafe battery packs come in at under the 100-watt-hour limit, so traveling should be easy with one.

Consider the extra features. You may not need them, but the little extra perks of a MagSafe power bank can come in handy. Some have stands so you can watch your phone while it refills. Some have LED displays that tell you how much charge is left, which can be a little more precise than the lighted pips other banks use. Some also have straps to make the bank easier to carry around or fish out of your bag.

What about the iPhone Air MagSafe Battery?

When Apple introduced the iPhone Air, it announced the new $99 iPhone Air MagSafe Battery in the same breath. It’s now the sole Apple-branded MagSafe power bank — but it only works with the iPhone Air. It’s a pretty divisive battery. In his review of the new phone, Engadget’s Sam Rutherford appreciated that the accessory keeps with the sleekness of the iPhone Air design and liked that it can also charge the new AirPods 3 wirelessly. But Valentina Palladino called out its dismal price-to-capacity ratio.

Anker’s Nano MagGo Slim is probably a better bet for all but the most devoted iPhone user. It has the same minimalist look and pocketable thinness as Apple’s proprietary battery, but it’ll attach to other phones in addition to the Air. Plus it’s $35 cheaper.

Other MagSafe batteries we tested

Torras MiniMag power bank

Among the first results when I search for MagSafe power banks on Amazon is the Torras MiniMag power bank, so I thought I’d check it out. The max wireless charging output is 7.5 watts, but it was actually pretty speedy in refilling an iPhone 15, giving it a little less than 80 percentage points in about two hours. The battery itself recharges a bit slowly, and it’s a bit expensive at its full MSRP of $60, but it comes in pretty colors and if you can catch it on sale, it’s a decent choice.

Mophie Powerstation Slim 5K

The Mophie Powerstation Slim 5K, too, has a super slim design that nearly disappears into the back of the phone as it charges. It makes excellent use of its 5K capacity, delivering a 90 percent refill to an iPhone 15. But it’s a little more expensive than the our top slim pick, Anker’s Nano MagGo Slim, and the squared off design makes it feel bulkier than it actually is. Neither of those make it a bad choice; the MagSafe battery playing field is just terribly competitive right now.

Belkin BoostCharge Pro 10K

Belkin’s BoostCharge Pro is Qi2-certified and was only a touch slower than other models in terms of charging speeds, boosting an iPhone 15 from 5 percent to full in about two and a half hours. The feel is premium and the stand is sturdy, but it got quite hot during charging, took overly long to refill itself and is pricer and a bit bulkier than similar models.

Baseus Picogo 5K

The Picogo 5K from Baseus is teensy but still packs a stand and a 5,000mAh capacity. It’s Qi2-certified and delivered a 43 percent bump to our tester iPhone 15 in 42 minutes, ultimately charging it to 91 percent. The slim slab of the Anker Nano battery is sleeker. But that one doesn’t have a stand — so if you want to prop up your phone while it charges, go for this one.

MagSafe power banks FAQs

What does MagSafe do?

MagSafe is Apple’s own technology that supports up to 25W wireless charging speeds and incorporates embedded magnets to align the phone with chargers and other accessories.

Which iPhones support MagSafe?

iPhones 12 and later support 15W MagSafe technology, though only iPhones 13 and later can reach the 15W charging speed with third-party Qi2 accessories. The iPhone 12 maxes out at 7.5W with non-Apple accessories.

The new iPhone 17, 17 Pro and 17 Pro Max support up to 25W charging speeds with Qi2 25W-certified chargers. iPhone 16, 16 Pro and 16 Pro Max should also support those speeds after an update to iOS 26. The iPhone Air supports MagSafe charging at a max speed of 20W.

Can you use MagSafe batteries with a case?

In most cases (heh), yes. The wireless charge can travel across a distance of a few millimeters. If the case is more than 5mm thick or contains metal components, the wireless charge can be blocked. Many iPhone cases are marketed as MagSafe-compatible, which means the case itself has complimentary magnets inside and should not interfere with charging accessories. We tested a MagSafe power bank on an iPhone 15 with and without a MagSafe case and got the same charging speeds and amounts in both tests.

How much power do MagSafe batteries provide?

That depends on the power bank. If it is Qi2-certified, it can provide up to 15 watts of wireless power. Qi2 25W-enabled chargers can deliver up to 25 watts to a compatible handset. Non-Qi2 batteries typically deliver around 7.5 watts.

The amount of charge delivered depends on the capacity. Most MagSafe portable chargers are rated at 5,000mAh or 10,000mAh. The former can get a standard iPhone 15 from five percent to around 90 percent. The latter can fill the phone completely with enough left over for another half charge.

Last year, I experienced my first iPhone launch cycle at Engadget and the fanfare got to me. It seemed I couldn’t call myself a respectable member of the tech world if I didn’t own any of the shiny new tech. So I headed to the Apple store on the iPhone 15’s opening weekend and put my name in to buy one. As I waited my turn, I idly played with the display model. Holding it up to my iPhone 11, my enthusiasm dimmed. A bright grid of apps, softly rounded corners, one button on the right, two buttons and a toggle on the left… These two phones were the same. Sure, the pill-shaped thing on the screen was new, but, so what?

Instead of splurging, I left the store with my old phone. One year later, as this week’s iPhone 16 event approached, the thought of upgrading my phone hadn’t really crossed my mind. I was more concerned with the real-time transcription abilities I’d need to help cover the event.

But then Apple went and announced a brand new feature for the iPhone 16. While rumors suggested the DSLR-like focus button (now known as the Camera Control) would grace only the Pro models, every iPhone announced this year actually got the fancy new thing. And the Action button from the 15 Pro would now be on the base model as well. Additionally, there’s a new “fusion camera” that combines a 48MP sensor with a 2x telephoto lens. I may not know what that really means, but anything that might help me take better pictures of cityscapes is a plus.

Of course, the new button was likely added because it’ll serve as the interface for October’s upcoming Visual Intelligence, Apple’s AI-fueled feature that interprets the real world through the lens of Apple Intelligence. Given that shareholders insist AI’s buzz be shoved into everything, it’s not surprising that Apple’s best selling product would have all the tools it needs to embrace the tech fully. AI isn’t something I need, but two new buttons? And one that seems potentially pretty cool? It’s enough to lure me to upgrade.

I’m not much of a shopper. I wear six-year old t-shirts, own seven pairs of shoes and still carry an iPhone 11. I’m not necessarily proud of these facts; the experience of buying A New Thing often just leaves me cold, particularly when the stuff I have still works just fine.

Up until now, every iPhone I’ve replaced was for a good reason: Three years in, the battery on my iPhone 3GS stopped holding a charge. After the same amount of time, my iPhone 7 got so slow I’d forget what I was trying to do before an app would open.

Conspiracy theories once abounded that Apple purposely built planned obsolescence into their handsets, but I think a saner reason was that battery and chip technology just weren’t where they are now. With the release of iOS 17, Apple dropped feature update support for the iPhone 8, but a security update went out as recently as last month. That’s nearly seven years of reasonable use (and I have family members with iPhone 8s who have no plans to upgrade anytime soon).

I got my iPhone 11 in early 2020 and, four and a half years later, it’s still an entirely serviceable device. I can play my daily games, waste time on Reddit, keep in contact with friends and family using their various preferred methods and take pictures of tall buildings and overhead wires that turn out pretty decent. The battery won’t last through a whole day if I’m relying heavily on navigation, though that’s not a huge problem for me — I have far too many power banks laying around to ever end up with a dead phone. But it won’t last forever.

The new iPhone 16 costs $799 — the same price as the iPhone 15 went for — and it comes in a new ultramarine color. It’s sort of a purply royal blue that I’m very drawn to and represents just the sort of superfluous, consumerist frivolity that provokes post-shopping dejection. But it’s so pretty! Granted, I'll never really see that deep, blue-hour shade. The moment I get this new phone, it’s going directly into a case, where it will stay until the next time I upgrade — maybe around 2030 or so.
