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: plenty of "MagSafe-compatible" banks charge at just 7.5W, Qi2-certified ones manage the standard's full 15W. The newest Qi2 25W class goes faster still, but only on recent iPhones. This guide picks three magnetic banks that get the standards right. If you'd rather have the faster wired kind, our power bank for iPhone 15 guide covers that side.
Top picks
1. Anker MagGo Power Bank 10000mAh Qi2 15W - Best Overall
SPP Score: 7.5 / 10 - Qi2 15W wireless with a foldable stand and live display. Our all-round pick.
Capability 6/10 - Versatility 8/10 - Build 9/10 - Value 8/10
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 proper 15W, not the 7.5W of loosely "MagSafe-compatible" slabs. 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 - the proper standard, not the 7.5W kind
- ✓ 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
- ✗ Like all magnetic banks, wireless top-ups drain the cell faster than its wired port does
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 chasing the fastest possible wireless numbers on an iPhone 16 or 17.
2. INIU Slimmest Power Bank 5000mAh Qi2 15W - Best Budget
SPP Score: 6.2 / 10 - Qi2 15W in the smallest, lightest pack here. Our value pick.
Capability 4/10 - Versatility 7/10 - Build 8/10 - Value 7/10
The budget route into real Qi2 is also the one you'll forget you're carrying: a 5000mAh pack slim enough to stay snapped on the phone in a pocket without turning it into a brick. It charges at the full Qi2 15W, and INIU's listing includes a USB-C cable and a stand in the box, which is generous at this end of the market. 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. If you'd rather skip the magnets entirely, our power bank under 30 guide covers the wired budget end.
Pros
- ✓ Genuine Qi2-certified 15W magnetic charging, not a 7.5W lookalike
- ✓ 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 the lightest genuine Qi2 pack 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: 7.2 / 10 - Qi2 25W wireless with a built-in USB-C cable and battery display. Our pick for maximum capability.
Capability 7/10 - Versatility 8/10 - Build 7/10 - Value 7/10
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 different league from 7.5W slabs. 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
- ✗ Per UGREEN's compatibility notes, the full 25W needs an iPhone 16 or 17-era handset - older models cap at 15W
- ✗ The built-in cable can't be swapped if it frays, unlike a separate lead
Who it's for: iPhone 16 and 17 owners who want the fastest snap-on charging available. Who it's not for: Owners of older iPhones, who'd pay for a 25W ceiling their phone can't reach.
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. If you want the lightest genuine Qi2 pack for daily top-ups, the INIU Slimmest Power Bank 5000mAh Qi2 15W covers it. And if your phone is an iPhone 16 or 17, the UGREEN MagFlow Power Bank 10000mAh Qi2 25W (Built-in Cable) is the one bank here that uses everything your handset can take. If you're still buying the plug that goes with a new iPhone, our iPhone 17 charger guide covers that end.
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, not "MagSafe-compatible" 7.5W lookalikes. 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 UK buyers. Wireless standards are exactly where listings blur the details, so follow each link to the live Amazon UK 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 is plain Qi at 7.5W. Qi2 is the certified standard that delivers 15W to compatible iPhones, and the newer Qi2 25W class raises that again - but only iPhone 16 and 17-era handsets can use the full 25W.
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.
Q: How many charges will a 10000mAh magnetic bank give an iPhone? A: Fewer wirelessly than wired - some energy is lost as heat, so expect roughly one and a half full charges over the magnets versus closer to two through the cable; halve that for the 5000mAh budget pick. 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 - even the 10000mAh picks (roughly 37Wh) sit comfortably under the usual 100Wh cabin-baggage limit, and the 5000mAh budget pick is smaller still. Keep it in hand luggage, never checked bags, and check your airline's own rules if you're carrying several.
