Read our full review →KEY TAKEAWAYS
UGREEN MagFlow
Qi2 25W wireless
The fastest magnetic wireless class, close to wired speed on iPhone 16 and 17. Older iPhones cap at 15W.
Built-in cable
A built-in nylon-braided USB-C cable plus a separate USB-C port, both 30W wired. One fewer loose lead in the bag.
Airline carry-on
36Wh, well under the 100Wh cabin limit, so it travels carry-on across the UK, EU and US with no approval needed.
Three at once
Charges three devices at the same time, two on the wired ports plus one on the magnetic pad.
Independently reviewed
Macworld Editor’s Choice, with positive verdicts from Trusted Reviews, AVForums and Cult of Mac.
Strong magnet hold
17 N52 magnets give a 9N hold, strong enough to stay put in a pocket or bag mid-charge.

Most magnetic power banks make you choose between a clean magnetic snap and actual charging speed. Snap one onto an iPhone and the charge crawls in at 15W while the back of the phone warms up. This UGREEN MagFlow review covers the first magnetic bank that closes that gap, because it is the first to carry Qi2 25W certification.
For this UGREEN MagFlow review, Alan, a network engineer with nine years of industry experience, assessed the charging behaviour and magnet design against independent testing from Macworld, Trusted Reviews, AVForums and Cult of Mac. Alan does not own this unit, so every performance figure below is attributed to a named source. See how we test for the full methodology.
First Impressions
Out of the box the MagFlow reads as a premium bank rather than a budget magnetic puck. The shell is matte, the built-in cable tucks flat along one edge, and the digital display wakes the moment you press the side button. The first thing most owners notice is the magnet. The 17 N52 array grabs an iPhone with a firm click and holds it through a pocket or a bag without creeping, which is the single most common complaint about weaker magnetic banks.
Design and Build
The pack holds 10,000mAh (36Wh) in a 21mm-thick body that weighs 254g. That weight is the honest trade-off here: the MagFlow is noticeably heavier than a slim 15W bank, and you feel it when phone and bank ride together in one hand. In return you get a built-in nylon-braided USB-C cable and a separate USB-C port, both rated for 30W wired charging, plus a digital display that shows the remaining percentage rather than four guesswork LEDs.
UGREEN sells it as Qi2 25W certified. Some retailers label the same unit Qi2.2, but both names point to the same 25W magnetic standard, so the labelling is not worth losing sleep over.
UGREEN MagFlow Review: Charging Performance
The headline is 25W magnetic wireless output. Older MagSafe-style banks cap at 15W, so the MagFlow is one of the first you can buy that reaches the higher Qi2 ceiling. There is a real catch worth stating plainly: the full 25W only lands on the iPhone 16 and iPhone 17 series running the latest iOS. An iPhone 12 through 15 still draws 15W from this bank, the same as a cheaper one.
The independent numbers back the speed claim. Cult of Mac measured an iPhone 16 going from nearly empty to 50% in about 30 minutes on the wireless pad, with an iPhone 15 taking closer to 45 minutes, which shows the gap between a 25W-capable phone and an older 15W one. UGREEN’s own figures put an iPhone 17 Pro Max at 50% in roughly 38 minutes. Macworld named it an Editor’s Choice and called it a leader among magnetic banks, with Trusted Reviews and AVForums reaching similar conclusions.
Pass-through charging
The MagFlow also supports pass-through charging, meaning it can power your phone while the bank itself is plugged in and recharging. Verified UGREEN buyers confirm it pulls up to 30W through the USB-C port for this, which is handy for an overnight setup where one wall socket tops up both the bank and your phone.
Portability and Travel Use
At 36Wh the MagFlow sits far below the 100Wh cabin limit, so it travels in carry-on without airline approval. The 10,000mAh capacity covers close to two full phone charges, which is the sensible middle ground for a travel day: enough to get through a long flight and a transfer, without the bulk of a 20,000mAh brick. The built-in cable earns its place here, because it means one fewer loose lead in the bag.
At 36Wh the UGREEN MagFlow is well under the 100Wh carry-on limit, so it flies in your cabin bag across the UK, EU and US with no airline approval needed. Keep it in the cabin, never in checked luggage.

Why We Rated It 8.5/10
Charging Speed scores 9.0 because the 25W magnetic ceiling is the fastest wireless class you can buy, and the independent timings from Cult of Mac and Macworld put it at the front of the magnetic pack on a current iPhone. Carry Rating takes 8.0: the 36Wh capacity is carry-on friendly and the size is pocketable, but 254g is the honest weak point against a slim 15W rival. Value for Money sits at 8.0, fair for the first Qi2 25W bank, though the premium only makes sense if your phone can use the 25W. Port and Cable Design earns 9.0, because a built-in cable, a separate 30W port, a strong magnet array and a real display is a complete hardware package.
The UGREEN MagFlow scores 8.5 because it is the first magnetic bank to make wireless charging feel genuinely fast, as long as you own an iPhone 16 or 17. Strong magnets, a built-in cable and a digital display round out a well-made pack, and the independent reviews stay consistently positive. It concedes on weight, since 254g is the honest cost of the bigger magnet array and battery. On an older iPhone, a cheaper 15W bank charges at the same rate.
BUY IF
- You own an iPhone 16 or 17 and want wireless charging near wired speed.
- You want a strong magnet hold and a built-in cable in one pack.
SKIP IF
- You carry an iPhone 12 to 15, where it drops to 15W anyway.
- You want the lightest possible bank and do not need 25W.

Alternatives to the UGREEN MagFlow
UGREEN Ultra-Slim 10,000mAh (cheaper, same capacity)
If your phone caps at 15W anyway, the UGREEN Ultra-Slim gives you the same 10,000mAh capacity and a built-in cable for less money. It is the honest pick for an iPhone 12 to 15, where the MagFlow’s 25W headline does nothing you can use. It sits below the MagFlow on price and runs on the same UGREEN line.
UGREEN Ultra-Slim 10,000mAh (Qi2 15W)
Same 10,000mAh capacity at 15W with a built-in cable, the cheaper UGREEN pick for iPhone 12 to 15.
Anker MagGo 10,000mAh (trusted brand, with a stand)
The Anker MagGo is the brand-name option, also 15W, with a foldable kickstand and a clear display that earns its keep if you prop your phone up to watch while it charges. It holds a 4.4 out of 5 rating across more than 8,000 Amazon ratings, so it is a safe, well-supported choice for anyone who values Anker’s track record.
Anker MagGo 10,000mAh (Qi2 15W)

UGREEN MagFlow Review: FAQs
Is the UGREEN MagFlow worth it?
Yes, if you own an iPhone 16 or 17. Those phones draw the full Qi2 25W, which is where the MagFlow pulls ahead of older 15W banks. On an iPhone 12 to 15 it drops to 15W, so a cheaper bank makes more sense.
Does the MagFlow charge older iPhones at 25W?
No. The 25W wireless speed needs an iPhone 16 or 17 on the latest iOS. An iPhone 12 through 15 charges at 15W from this bank, the same rate as a standard MagSafe-style bank.
What is the difference between Qi2 and Qi2.2 on the MagFlow?
Nothing that matters here. UGREEN labels the MagFlow Qi2 25W certified, and some retailers call it Qi2.2. Both names refer to the same 25W magnetic charging standard.
Can you take the UGREEN MagFlow on a plane?
Yes. At 36Wh it sits well under the 100Wh cabin limit across the UK, EU and US, so it travels in your carry-on without airline approval. Keep it in the cabin, never in checked luggage.
How many times can the MagFlow charge an iPhone?
The 10,000mAh capacity covers close to two full charges of a current iPhone, depending on the model and whether you charge wired or wirelessly.
Does the MagFlow have a built-in cable?
Yes. It carries a built-in nylon-braided USB-C cable plus a separate USB-C port, both rated at 30W, so you can charge wired and wireless at the same time.
How strong are the magnets?
The MagFlow uses a 17 N52 magnet array rated at a 9N hold, which independent reviewers found strong enough to keep the bank attached through normal pocket and bag movement.
Is the MagFlow good for Android phones?
Android phones can use the MagFlow over the wired USB-C ports at up to 30W. The magnetic wireless pad needs a MagSafe-compatible phone or case to attach, so most Android users will rely on the cable.
For the right phone, the UGREEN MagFlow is the upgrade that turns magnetic charging into your main method rather than an overnight afterthought. If you carry an iPhone 16 or 17 and want wireless speed close to a wired cable, it is the magnetic bank to buy. If you are on an iPhone 12 to 15, save the difference and pick a 15W bank. Either way, see how we reach our verdicts on our how we test page.
