If you have never thought about whether your power bank has CryoPulse technology or a Cyber Window, Ugreen has a new product that may change your perspective. The company's MagFlow Pro Magnetic Power Bank is launching today at a fairly steep $149.99, putting it well above many other 10,000mAh portable chargers. But this one offers something unusual: a liquid cooling system, visible through a small transparent cutout, designed to keep both the charger and your phone cooler while wireless charging. Ugreen is positioning it as the world's first liquid-cooled power bank with wireless charging, and the feature set suggests the premium price is about more than just a larger battery.
A cooling system you can watch
On the front of the MagFlow Pro is a transparent Cyber Window, and behind it you can see a small pump moving coolant through a network of channels. This is not just a gimmick. The cooling loop works alongside copper foil and a thoughtfully laid out internal design that keeps the most heat-generating components separated. Ugreen calls the overall thermal solution CryoPulse, and it is specifically meant to protect the power bank's 10,000mAh battery and the Qi2.2-compatible wireless charging coil from excessive heat.
Wireless charging is convenient, but it is also less efficient than using a cable. The energy that does not make it into your phone is turned into heat, and that heat has to go somewhere. With magnetic wireless chargers, the heat can build up quickly, especially when the phone is also using navigation, streaming video, or otherwise working hard. The MagFlow Pro's active cooling moves heat away from the charging pad and distributes it over a larger area, helping the phone maintain more efficient charging speeds. In practice, this could also lead to a cooler touch when you pick up the power bank after a long charging session.
Why heat management is critical for power banks
Lithium-ion batteries do not like extreme temperatures. When a power bank or phone battery gets hot, internal resistance rises, charging efficiency drops, and the chemistry inside the cell ages faster. Over time, repeated exposure to heat can reduce a battery's capacity and make it less reliable. Many phones and batteries already have software-based temperature management systems, but those systems often work by reducing power rather than by actively removing heat.
Ugreen's MagFlow Pro takes a different path. The liquid cooling system pulls heat away from the wireless charging coil and other components, which means the power bank can keep delivering up to 25W of wireless output without having to step down as aggressively when temperatures climb. Keeping components physically separated inside the enclosure also helps avoid localized hotspots. Copper foil is used as a thermal spreader, moving heat away from the battery and toward the surface of the device, where it can dissipate more easily.
The benefits are twofold. First, your phone may not get as warm while charging, which is better for its battery. Second, the power bank itself should have a longer working life because the cells inside are being kept at more moderate temperatures. For people who charge their phones while gaming, using augmented reality, or recording video, this kind of thermal management can make a real difference.
Charging specifications and flexibility
The MagFlow Pro is not just a wireless charger. It also includes a built-in USB-C cable that acts as a lanyard, meaning you cannot forget to bring a charging cord with you. That cable can supply power to a second device, and there is another USB-C port on board for a third. The power bank supports up to 25W of wireless output through its magnetic charging surface, while the USB-C cable and USB-C port are each capable of up to 45W. However, the total maximum output for the entire MagFlow Pro is 45W, so when you charge multiple devices at once, the power available to each device will be spread out.
For example, if you are wireless charging a phone and also using the USB-C cable to charge a pair of headphones, the power bank will adjust the distribution based on the demands of each connected device. If you want the fastest possible charging for a phone, a wired connection is still the better choice. But for overnight charging or desktop topping up, the magnetic wireless charging pad offers an easier experience. The built-in cable is a particularly thoughtful touch, because it turns a wearable strap into a functional charging cable. This is a space-saving design that makes it easier to pack the power bank in a bag or clip it to a backpack without worrying about losing the cable.
The 10,000mAh capacity is enough to charge most modern smartphones from empty to full once, with some charge left over. It is not a high-capacity travel power bank that can charge a laptop and a phone multiple times, but it is sized for daily portable charging. The emphasis here is on convenience and thermal stability rather than raw capacity.
Positioning and price
At $149.99, the MagFlow Pro is considerably more expensive than many other 10,000mAh power banks. There are plenty of compact options available for a third of that price. The extra money buys the liquid-cooling hardware, the transparent Cyber Window, the integrated USB-C lanyard cable, and the Qi2.2-compatible wireless charging pad. For users who have suffered from overheated power banks or phones that refuse to charge at full speed because of temperature limits, the extra price may be justified.
Ugreen is known for offering a wide range of charging accessories, from cables and adapters to hubs and power stations. The MagFlow Pro is not the company's first magnetic power bank, but it is clearly the most feature-rich. The company describes the device as a glimpse into where power banks are heading, especially as wireless charging standards improve and phones become more reliant on battery-hungry features. Adding an active cooling loop to a tiny portable device requires precision engineering, and this product shows that such technology can fit into a form factor that still fits in a pocket.
The launch comes at a time when many consumers are also looking at newer battery chemistries, faster wired charging speeds, and more efficient wireless charging. The MagFlow Pro is not necessarily the answer to every charging problem, but it does address one of the most common and least visible issues: heat. Being able to see the coolant flow is a clever way to make that invisible problem visible, and it reinforces Ugreen's claim that something is happening inside the power bank to actively manage temperature.
The MagFlow Pro Magnetic Power Bank is available starting today for $149.99 from Ugreen's online store and other retailers. It will be an interesting option for anyone who wants a premium 10,000mAh power bank that does more than just deliver electrons. Whether the liquid cooling system provides a meaningful long-term advantage remains to be seen, but it is certainly a unique and mechanically fascinating approach to extending the life of both the power bank and the phone it charges.
