UGREEN’s ‘world’s first’ liquid-cooled Qi2.2 power bank keeps iPhone charging surprisingly cool [Deal]

UGREEN has been going pretty hard on Qi2.2 accessories lately, and the MagFlow Pro 25W power bank is easily one of the more interesting additions to the lineup. There are plenty of magnetic Qi2-certified 25W power banks out there now, including UGREEN’s own standard MagFlow model, but this one adds something we haven’t seen before on a portable battery pack – an active liquid-cooling system. It might sound a little excessive at first, but it ended up being the feature I noticed most while using this unit for a few weeks now. Below are a few things you need to know if you’re planning to pick this power bank for your EDC.

9to5Toys’ Take

Let’s get straight to the main point here and talk about how effective the liquid cooling actually is. Not only is it the main selling point of the MagFlow Pro battery pack, but it’s also the first thing I noticed during real-world use. The difference is pretty obvious, especially if you’ve used other Qi2 25W or even 15W magnetic power banks before. In fact, I can confidently say the MagFlow Pro is in a completely different league when it comes to keeping temperatures in check. UGREEN has built the liquid-cooling system into the rear of the battery pack, and while the exposed design gives it a bit of flair, it’s clearly doing more than just looking cool. Even while wirelessly charging my iPhone 16 Pro, the MagFlow Pro itself stayed surprisingly cool throughout my testing. More importantly, the phone stayed relatively cool as well.

That matters quite a bit with a magnetic power bank because it sits directly against the back of your phone. If the battery pack starts getting warm, you’ll feel it every time you pick up and use your phone. With the MagFlow Pro attached, I was perfectly comfortable continuing to use my iPhone while it charged.

The magnetic connection is also reassuringly strong, which is something we’ve already seen with other UGREEN magnetic charging accessories. This is still a 10,000mAh power bank, so you’ll definitely notice some extra weight on the back of your phone, but it never felt awkward enough to make me want to take it off.

The MagFlow Pro supports up to 25W Qi2.2 wireless charging, and in practice the overall charging speeds felt pretty comparable to a lot of the other Qi2.2 power banks I’ve tested. I didn’t notice some huge jump in charging performance just because of the liquid cooling, and it still performs much like other models when it comes to getting a phone topped up wirelessly. What the cooling does change is how the whole thing feels to use. The MagFlow Pro stays noticeably cooler than many of the alternatives I’ve tried, which makes it much more comfortable to keep attached to the back of the phone while charging.

Leaving full-charge times aside, this is also the kind of charging behavior that will probably matter more to a lot of people in day-to-day use. I think it’s fair to say most of us aren’t reaching for a power bank because we want to sit around and charge all the way to 100%; it’s usually because the battery is getting low and we just need enough juice to comfortably make it through the next few hours.

That’s pretty much how I ended up using the MagFlow Pro as well. During one of my tests, my iPhone 16 Pro went from around 15% to roughly 50% in about 20 minutes, which is a really useful amount of charge to gain in a short window. If you’re at an airport, heading out after lunch, or simply realize your battery is about to die, getting another 35% or so that quickly is often more useful than shaving a few minutes off a complete charge.

There are other Qi2.2 power banks that can hold onto their peak charging speeds for longer, but for quick top-ups on the go, those first 15 to 20 minutes are usually what matter most anyway, at least in my opinion. And that’s where the MagFlow Pro makes a strong case for itself, because it can deliver that useful burst of power without getting uncomfortably hot.

You can also skip wireless charging entirely and use the MagFlow Pro as a more traditional power bank. Wired output tops out at 45W, which gives you enough power for phones, tablets, handhelds, and even some smaller laptops. It won’t hold onto that peak output indefinitely during longer charging sessions, but one thing I noticed is that the battery itself still doesn’t get uncomfortably hot even when you’re pushing it over USB-C. I also like having the built-in USB-C cable here. It’s short, but it means there’s one less cable to remember when you throw the power bank into a bag. There’s also a separate USB-C port if you’d rather use your own cable or need another connection.

UGREEN has also worked a small display into the side of the unit. It shows the remaining battery percentage along with charging information, and while I wouldn’t call it an essential addition, I’ll take an actual percentage readout over the usual four tiny battery LEDs any day.

All things considered, though, the liquid cooling is easily what separates the MagFlow Pro from the growing pile of 25W Qi2.2 power banks out there. The difference was immediately noticeable after using it alongside some other Qi2.2 alternatives. Both the power bank and my iPhone simply stayed cooler, which makes a surprisingly big difference when the two devices are physically attached to each other.

Could you buy a cheaper 25W Qi2.2 power bank? Absolutely. And there are models out there that put more emphasis on sustaining the highest possible charging rate for as long as possible. But for everyday use, the MagFlow Pro makes a lot of sense if you mainly want quick top-ups without excessive heat. Being able to snap it onto your phone, gain a useful amount of charge in 15 or 20 minutes, and move on without either device feeling like a hot plate is a pretty compelling advantage. The UGREEN MagFlow Pro does exactly that, and the liquid-cooling system ends up feeling far more useful than it might sound on paper.
