A magnetic power bank snaps onto the back of an iPhone and charges it with no cable in sight, which is exactly what you want on a train or walking between meetings. The catch is the wattage trap: a bank that only sticks on charges over plain Qi, which Apple rates at up to 7.5W on an iPhone, while Qi2 certification brings the standard's full 15W. The newest Qi2 25W class goes faster still, but only on recent iPhones.
Top picks
1. Anker MagGo Power Bank 10000mAh Qi2 15W - Best Overall
SPP Score: 9.0 / 10 - Qi2 15W wireless with a foldable stand and live display. Our all-round pick.
Capability 8.0/10 - Versatility 8.9/10 - Build 9.4/10 - Value 8.9/10 - Fit 9.8/10
Fit for this guide: This guide wants genuine Qi2 speed, and this one is rated for the full 15W, with 10000mAh and a foldable stand behind it.
Every pick here is scored out of 10: four marks rate the product and are the same in every guide, and the fifth rates its fit for this guide - how we test and score.
The MagGo is the magnetic bank that earns a place on the desk as well as in a bag. Because it's Qi2-certified you get the standard's full 15W. The foldable stand turns out to be the sleeper feature - plane tray, desk, bedside, wherever the phone needs propping while it drinks - and the small display takes the guesswork out of what's left. When speed beats convenience, Anker rates the wired USB-C port at up to 27W.
Pros
- ✓ Qi2-certified 15W magnetic charging
- ✓ Foldable stand holds the phone at an angle while it charges
- ✓ Display plus 27W wired USB-C when you'd rather plug in
Cons
- ✗ Wireless tops out at 15W, and the newer 25W class now exists for recent iPhones
- ✗ With the stand and the display it is the bulkiest of the three to leave snapped on a phone
Who it's for: iPhone owners who want snap-on charging with a stand for desk, travel and video calls.
Who it's not for: Anyone with a handset Apple lists at 25W who wants every watt of it.
2. INIU Slimmest Power Bank 5000mAh Qi2 15W - Best Budget
SPP Score: 8.3 / 10 - Qi2 15W in a slim 5000mAh pack. Our value pick.
Capability 7.1/10 - Versatility 8.5/10 - Build 8.9/10 - Value 8.5/10 - Fit 8.9/10
Fit for this guide: Qi2-certified 15W magnetic charging in an ultra-slim 5000mAh body fits readers wanting daily snap-on charging.
The INIU is the Qi2 pack you'll forget you're carrying: a 5000mAh body slim enough to stay snapped on the phone in a pocket without turning it into a brick. INIU's listing includes a USB-C cable and a stand in the box. Half the capacity of the other two picks is the honest trade: this is the top-up-and-go option, not the all-weekend one.
Pros
- ✓ Qi2-certified, so it charges at the full 15W
- ✓ Slim, light 5000mAh build that lives on the phone comfortably
- ✓ USB-C cable and stand included, per INIU's listing
Cons
- ✗ 5000mAh is roughly one fast top-up, not a full weekend of charges
- ✗ Wireless top-ups run the cell down faster than its USB-C port does
Who it's for: Anyone who wants a slim genuine Qi2 pack to leave on the phone for daily top-ups.
Who it's not for: Heavy users who need a full charge or two in reserve - the 10000mAh picks above and below cover that.
3. UGREEN MagFlow Power Bank 10000mAh Qi2 25W (Built-in Cable) - Best Premium
SPP Score: 8.6 / 10 - Qi2 25W wireless with a built-in USB-C cable and battery display. Our pick for maximum capability.
Capability 8.5/10 - Versatility 8.9/10 - Build 8.5/10 - Value 8.5/10 - Fit 8.5/10
Fit for this guide: Handsets Apple lists at 25W get the full magnetic speed here, from Qi2 25W and a built-in cable.
The MagFlow is the pick for the newest iPhones. It carries the Qi2 25W standard, which UGREEN pitches as its fastest magnetic charging for the iPhone 16 and 17 era. A built-in USB-C cable handles wired charging at PD 30W, and a battery display keeps the guesswork out. On an older iPhone it still works magnetically, just at the 15W the phone itself allows.
Pros
- ✓ Qi2 25W wireless - the fastest magnetic class, per UGREEN's rating
- ✓ Built-in USB-C cable means wired charging with nothing extra to pack
- ✓ Battery display plus PD 30W wired output round it out
Cons
- ✗ The full 25W needs a handset Apple lists for it - an iPhone 17, or a 16 Plus or 16 Pro Max; everything older caps at 15W
- ✗ The built-in cable can't be swapped if it frays, unlike a separate lead
Who it's for: iPhone 17 owners, and iPhone 16 Plus and 16 Pro Max owners, whose handsets Apple lists at the full 25W.
Who it's not for: Owners of older iPhones, whose phones can't reach its 25W ceiling.
Quick verdict
For most people the Anker MagGo Power Bank 10000mAh Qi2 15W is the one to get: proper Qi2 speed, a stand that earns its keep daily, and a display that tells you what's left. For a slim 5000mAh pack that stays on the phone, take the INIU Slimmest Power Bank 5000mAh Qi2 15W. And if your iPhone takes 25W, the UGREEN MagFlow Power Bank 10000mAh Qi2 25W (Built-in Cable) is the one bank here that uses all of it. If you're still buying the plug that goes with a new iPhone, our iPhone 17 charger guide covers that end.
Which one for an iPhone 15?
Apple's iPhone 15 specs list "MagSafe wireless charging up to 15W", the same 15W the MagGo and the INIU are rated for, so the MagFlow's extra 10W goes unused. We'd pick the MagGo for an iPhone 15: it holds twice the INIU's 5000mAh. If you'd rather charge over a cable, the MagFlow's built-in one means no lead to pack, and our 20000mAh power bank guide covers bigger wired packs with no magnets at all.
How we chose
Magnetic banks live or die on the wireless standard they actually carry, so that came first: all three picks are Qi2-certified. Beyond that we weighed wired speed for when the cable is quicker, extras like stands and displays that change daily use, capacity against pocketability, and honest fit for buyers. Wireless standards are exactly where listings blur the details, so follow each link to the live Amazon page and check the Qi2 wording matches what your iPhone supports before you buy.
FAQ
Q: What's the difference between MagSafe-compatible and Qi2? A: "MagSafe-compatible" usually means the magnets line up but the charging underneath is plain Qi. Qi2 is the Wireless Power Consortium's certified standard: in its words, Qi2 "brought faster 15W charging to mobile devices certified for interoperability and safety", and Qi2 25W delivers "nearly 70% more charging power". Our Qi2 vs MagSafe explainer unpacks how the standard and the brand relate.
Q: Will a magnetic power bank work through my phone case? A: Through a MagSafe-compatible case, yes - the magnets are designed for it. Thick, rugged or non-magnetic cases weaken or break the grip, so caseless or a thin magnetic case is the safe assumption. Our do you need a MagSafe case explainer walks through when a case helps and when it gets in the way.
Q: How many charges will a 10000mAh magnetic bank give an iPhone? A: Fewer wirelessly than wired - some energy is lost as heat, so the same bank gets you noticeably less over the magnets than through the cable. If raw endurance matters more than convenience, a bigger wired bank from our long flights guide stretches further.
Q: Can I take one of these on a plane? A: Yes, with the usual care. Check the watt-hour figure printed on the bank against your airline's limit, keep it in hand luggage rather than checked bags, and check the rules again if you're carrying several.
