My daily carry has slowly become a juggling act. My iPhone needs a top-up by mid-afternoon, my portable fan needs to be charged constantly in this warm weather and my Apple Watch somehow runs out on the days I need it most. My bag used to hold three different chargers and a tangle of cables to go with them.
So when I got my hands on the Ugreen MagFlow Pro Magnetic Power Bank 10000mAh 25W, I had one question: can one power bank keep up with everything I carry? After two weeks of daily use, I’d break my answer into three parts: how flexible it is, how fast and cool it runs, and how well it’s built.
One power bank for every device
Not every device plays nicely with high-powered chargers. Plug some of my smaller gadgets into a fast charger and they either charge at a crawl or don’t charge at all. The MagFlow Pro supports low-power devices like watches and other accessories, and charges them safely. It sounds like a minor feature, but it has quietly become a deal-breaker for me. A power bank that only fast-charges phones is only doing half the job.
It also works with a wide range of fast-charging standards, including PD, QC, PPS, AFC, FCP and SCP, so whether you’re on an iPhone 17, a Galaxy S26 or an iPad Pro, you’re covered.
You get three ways to charge: Qi2 magnetic wireless charging, the built-in USB-C cable and an extra USB-C port. In practice, my iPhone sits on the magnetic pad, my trusty handheld fan uses the built-in cable and my Apple Watch cable plugs into the spare port. That’s three devices from one power bank, with no extra bricks to carry around.
Total output tops out at 45W, and both the port and the cable can each deliver up to 45W on their own. The catch is capacity. With three devices running at once, you’ll watch the battery percentage drop fast. It’s perfect for a quick top-up of everything, but don’t expect it to fill all three to 100 percent.
Fast and cool but with a caveat or two
On paper, the MagFlow Pro offers up to 25W of Qi2 wireless charging and up to 45W wired. How much of that your phone actually gets depends on the model. According to Ugreen’s spec sheet, my iPhone 16 Pro should reach up to 22W wirelessly. In real life, it averaged about 15W. It’s still quick, just not quite what the numbers promise.
Ugreen’s claims the newer iPhone 18 Pro Max charges at around 40 percent in 30 minutes over Qi2 25W, which is a fair guide to the kind of speed to expect on the latest phones.
Wired charging is where it shines. Both the built-in cable and the USB-C port can deliver up to 45W. When the power bank itself runs low, a full 0 to 100 percent recharge with a fast-charging charger took just about two hours.
Let’s talk about capacity. Inside are two 5,000mAh cells, which gives you the 10,000mAh in the name. After conversion losses, though, the rated capacity is 6,000mAh, and wireless charging loses a bit more on top of that. Ugreen claims the slim 10,000mAh body delivers up to 1.28 charges for the iPhone 18 Pro Max. If you’re a heavy user, you may find it runs out sooner than the “10000mAh” label suggests. Topping up over the cable will stretch it further than charging wirelessly.
The cooling system
The headline feature is the cooling system. The MagFlow Pro addresses the overheating common to fast wireless charging products. Its CryoPulse liquid-cooling system uses a micropump to circulate coolant, which you can watch through a see-through window on the back. A copper heat-spreading layer and the charging components are kept physically separate, all to cut down on heat.
In Singapore’s heat, where phones warm up just sitting in your pocket, that’s welcome. That said, if you expect dramatically faster charging because of the cooling, it may feel more like a nice-to-have than a game-changer. Still, I’ll admit I’ve spent more time than necessary watching the coolant flow.
Built to last and for travel
The MagFlow Pro feels expensive in the hand. Most sides have a metallic matte finish, and the magnetic side has a smooth silicone surface that grips the phone without scratching it. It measures about 108 x 71 x 16mm. At 220–230g, it’s a little on the heavier side, though not enough to bother me. Its 16+1 N52H magnets snap on with 8N of force and hold firmly.
The small screen is a highlight. Its subtle animations make it feel alive, and it shows genuinely useful information: wireless charging wattage, remaining battery, charge cycles and how long the battery will last at the current rate. No more guessing from four blinking dots.
My favourite perk is the built-in cable, which doubles as a strap around my fingers while I’m using my phone. Some may find a non-removable strap bulky in a pocket, but for me it means one less thing to forget.
Safety is where Ugreen really puts in the work. Its Dymondcell battery uses high-density ATL cells. According to the company, the battery survived repeated 4mm needle-puncture tests, a 2.5-tonne crush test, seven hours of continuous overcharging and a 140°C hot-box test without catching fire or exploding. Ugreen also claims it keeps 90 percent of their capacity after 800 charge cycles.
Travel and certification
One thing to note if you’re travelling to China: the MagFlow Pro does not carry CCC certification. I asked the Ugreen team why, and this was their reply:
“The MagFlow Pro’s 25W magnetic wireless charging speed exceeds the limit under the current Chinese standard, so this version does not carry CCC certification. The units supplied to Singapore meet the applicable local requirements.”
In other words, according to Ugreen, the missing CCC mark is down to the 25W wireless speed exceeding the limit under the Chinese standard and the Singapore units meet local requirements. If a China trip is coming up, though, it’s worth checking the rules before you pack it.
The verdict
At S$154, the MagFlow Pro sits at the higher end of the market. It is sold through Shopee, Lazada, TikTok Shop and Ugreen’s official website. A simpler magnetic power bank will get the basic job done for less. But none of those gives you this mix of safety credentials, active cooling, charging flexibility and speed.
If you carry more than one device and want a power bank that looks after all of them, the Ugreen MagFlow Pro is well worth a look.
