The UGREEN MagFlow Pro is a 10,000mAh magnetic power bank built for people who want iPhone power without carrying a mess of cables. It brings Qi2 25W wireless charging, a built-in USB-C cable, a small smart display, and what UGREEN calls visible liquid cooling into a compact everyday-carry package.
After spending time with it, this is one of those products that earns its place because it gets the important things right: the magnetic hold is solid, charging feels quick, the build feels premium, and most importantly, it stays dramatically cooler than the other magnetic battery packs I have used.
Key Takeaways
The MagFlow Pro combines a 10,000mAh battery, Qi2 25W charging, and a built-in bidirectional USB-C cable.
Its magnetic connection is strong, secure, and practical for carrying a phone while charging.
The liquid cooling keeps the power bank only slightly warm during repeated charging sessions.
The main drawback is the smart display, which is too dim for easy visibility.

What Comes in the Box
UGREEN keeps it simple. Inside the package, there is the MagFlow Pro power bank, a soft storage pouch, and the usual paperwork, including the manual and help guide.
The pouch is a nice touch. It is not something everyone will use every day, but it is useful for tossing the battery into a bag and keeping it separate from keys, cables, and other gear.
Design: Compact Magnetic Charging With a Built-In Cable
Right out of the box, the MagFlow Pro feels like a familiar magnetic wireless charger, but it is clearly built with some extra thought. The front has UGREEN branding and the Qi2 magnetic charging ring. It has a compact rectangular shape that sits cleanly on the back of a compatible phone.
One of the most useful features is the built-in USB-C cable. Pull it out from the bottom and it is ready to go. That means you can charge the power bank itself, charge another device by cable, or use the cable as another charging option when wireless charging is not the move.
The cable is bidirectional, which adds flexibility. You can charge into the power bank through it, and you can use it to send power out. There is also a separate USB-C port on the unit, so there are multiple ways to keep your devices powered depending on what you have with you.
That matters in real life. Sometimes you want the clean magnetic setup on your phone. Other times you just need to plug in and keep moving.
Qi2 25W Wireless Charging and Magnetic Hold
The MagFlow Pro supports Qi2 wireless charging at up to 25W. Qi2 is the magnetic wireless charging standard designed to improve alignment between a charger and compatible devices. Proper alignment is a big deal because it helps keep charging consistent and removes the annoyance of placing a phone down, only to discover later that it was never actually charging.
For more background on the standard itself, the Wireless Power Consortium's Qi2 overview explains how magnetic alignment is intended to improve wireless charging reliability.
In day-to-day use, the magnet is strong. The MagFlow Pro snaps onto the phone easily, holds securely, and does not feel like it wants to slide off. That is exactly what I want from this style of charger. I can attach it, put the phone in a pocket, take it to the car, walk around with it, or sit through an hour of soccer practice without worrying that the battery pack is going to fall away.
The magnetic connection triggers charging quickly and holds firmly in place.
The wireless charging experience feels quick, and the magnetic alignment is solid enough to make this a practical grab-and-go battery instead of something you only use while sitting at a desk.
The Feature That Actually Stands Out: Liquid Cooling
The major difference between the MagFlow Pro and many other magnetic power banks is the cooling. UGREEN calls it visible liquid cooling, and there is an animated display meant to show the cooling activity through moving lines and a lava-flow style effect.
Now, I am going to be honest about the display in a second. But the cooling itself is the part that impressed me.
Most magnetic battery packs get noticeably hot when they are attached to a phone that is low on battery and still being used. They may not become impossible to touch, but they get hot enough that you definitely notice it. That problem gets worse in the summer, when the ambient temperature is already working against you.
The MagFlow Pro does not behave like those other packs. After repeated charging sessions, it gets only slightly warm. Not “ooh, that is warm” warm. Just slightly warm. That remained true during charging and while recharging the power bank itself.
That is a real win, especially for anyone who uses a magnetic battery pack while out and about. Heat is one of the biggest concerns with this kind of accessory, so having a pack that stays much cooler makes it easier to trust as an everyday option.
The Smart Display Is Useful, but Too Dim
There is a small LED display on the side that shows the battery percentage. It works, and it gives you a quick way to see how much power is left. The unit arrived with a partial charge, and the display showed the remaining percentage right away.
The cooling animation also appears in the display as lines moving back and forth. You can see the effect with the naked eye, but here is my one real negative: I wish the display were brighter.
It is difficult to see at some angles, and for my eyes it is not as easy to read as I would like. The animated cooling effect is there, but it is subtle. Even the smaller side display looks brighter than the main display area.
I went through the manual and did not find a brightness setting or another way to make it more visible. Maybe the lower brightness is intentional so it does not become distracting or consume extra power, but I still think this could be much more visually attractive if it had a bit more punch.
Build Quality and Everyday Carry
The build quality feels solid. The body has a premium feel, the magnetic connection is dependable, and the overall design makes sense for daily use. This is not a bulky battery pack that feels like a brick attached to the back of a phone.
There is one small cosmetic point: the surface picks up lint easily. It is not a deal-breaker at all, but it is something I noticed. If you are particular about keeping your gear looking spotless, expect to wipe it down from time to time.
For normal everyday carry, the 10,000mAh capacity is a sweet spot. It gives you meaningful backup power without turning the charger into something too large to carry comfortably. It works well for:
Long days away from an outlet
Commutes and car rides
Travel and busy creator days
Sporting events, practices, and outdoor time
Keeping an iPhone topped up while still using it
I primarily used it as a magnetic charger for my phone, and that is where it shines. Attach it, keep using the phone, and do not stress about the battery percentage for a while.
Is the UGREEN MagFlow Pro Worth It?
If you are tired of slow wireless charging, weak magnetic attachment, and battery packs that get too hot, the UGREEN MagFlow Pro is a strong option.
The combination of Qi2 25W charging, a 10,000mAh battery, a built-in bidirectional USB-C cable, and notably effective thermal management gives it a real advantage over the magnetic packs that simply get warm and do not do much about it.
The display needs to be brighter. That is the one point I would change. But the display is not the reason to buy this pack. The reason is that it charges quickly, attaches securely, feels well built, and stays only slightly warm even under the kind of conditions that make other magnetic power banks heat up.
For me, that has made it a go-to charger, especially when the weather is hot. UGREEN clearly put time and thought into this one, and it shows.
