Ugreen’s liquid-cooled power bank, the 10,000mAh MagFlow Pro Magnetic Power Bank, is now on sale for $149.99. The device pairs magnetic wireless charging with a small coolant loop that is visible through a window, putting thermal management at the center of an unusually costly power bank for its capacity.
The Verge reported that the MagFlow Pro became available September 3. Ugreen calls it the first wireless-charging power bank with a liquid-cooling system, a company characterization that has not been independently verified.
How does Ugreen’s liquid-cooled power bank work?
The MagFlow Pro uses a micro-pump to move coolant past components that include its Qi2.2-compatible wireless charging coil, according to The Verge. The coolant passes through a front-facing transparent section Ugreen calls the Cyber Window, allowing users to see fluid moving inside the unit.
Liquid cooling in this product is intended to carry heat away from charging hardware. Ugreen says the loop works alongside copper foil and a layout that separates charging components, helping control heat buildup and sustain wireless delivery of up to 25W. Those expected thermal and charging benefits are Ugreen’s claims.
A Techlicious reporter who saw the device at Ugreen’s launch event reported seeing bubbles travel through its window. The reporter also said the effect looked less bright in person than in Ugreen’s promotional images, while CGMagazine’s reviewer said the bank remained cool during an extended charging session. Those are individual observations rather than controlled performance tests.
Charging limits and connections
The MagFlow Pro supports Qi2.2-compatible magnetic wireless charging at up to 25W, The Verge reported. It also has a USB-C cable that serves as a lanyard and a separate USB-C port for wired charging.
Either wired connection can deliver up to 45W, but 45W is the power bank’s total maximum output, according to The Verge. That means charging more than one wired device at once divides the available power and can lower each device’s charging rate.
- Battery capacity: 10,000mAh
- Wireless charging: up to 25W
- Wired output: up to 45W total through the built-in USB-C cable and USB-C port
- Price: $149.99
CGMagazine reported Ugreen’s additional performance claims: peak temperatures can run up to 18 degrees Fahrenheit below what the company describes as a 118-degree industry benchmark, and an iPhone 17 Pro Max can reach 50% charge in 40 minutes. The outlet did not independently validate those figures.
The key distinction for buyers is that the window is not only decorative: it displays an active pumped cooling loop. Whether that feature justifies the $149.99 price depends on how much a buyer values 25W wireless charging and added heat control in a portable 10,000mAh battery.
