Ugreen has unveiled a new power bank that attempts to solve one of portable charging’s biggest and most persistent problems: heat. The MagFlow Pro Magnetic Power Bank, available starting today for $149.99, is a 10,000mAh device with a feature set that sounds pulled out of a science fiction gadget catalog: CryoPulse technology and a Cyber Window. While those names might feel like marketing buzz, the actual functionality behind them is remarkably tangible. The power bank includes a visible liquid-cooling loop, something rarely seen in consumer electronics of this size, let alone in a battery pack meant for everyday phone charging.
The MagFlow Pro’s headline feature is a micro-pump that circulates coolant through the interior of the power bank. This coolant draws heat away from key components, including the device’s wireless charging coil. The charging coil supports the Qi2.2 standard, which allows for magnetic alignment and faster wireless power delivery. According to Ugreen, the liquid-cooling system works alongside copper foil and a component layout that keeps heat-generating parts physically separated. The goal is to reduce heat buildup not just during the charging process, but across the entire lifespan of both the power bank and the phone connected to it. Ugreen also claims that the cooling setup helps the MagFlow Pro maintain up to 25W of power delivery during wireless charging without throttling, and that the exterior remains cooler to the touch after extended sessions.
Perhaps the most intriguing aspect for potential buyers is the Cyber Window. On the front of the power bank, a transparent opening reveals the coolant as it flows through tiny channels. This is not just a decorative gimmick; it gives users a real-time visual confirmation that the cooling system is active. Watching blue liquid course through the device adds a surprising layer of transparency, quite literally, to what usually remains a sealed black box. For tech enthusiasts who appreciate visible engineering, this window turns a normally mundane charging accessory into a conversation piece.
Why heat is the enemy of power banks
Heat has always been a major issue for power banks and the devices they charge. Lithium-ion batteries degrade faster at higher temperatures, and wireless charging is particularly inefficient because energy is lost as heat during the inductive coupling process. Many power banks struggle to deliver high charging speeds without getting uncomfortably warm, and some reduce their output automatically to protect internal components. This thermal throttling can lead to longer charging times and a frustrating user experience. Ugreen’s liquid-cooling approach aims to address these issues head-on by actively moving heat away from critical areas and dispersing it across a larger surface area. If the system works as advertised, it could allow the MagFlow Pro to sustain higher charging rates for longer periods than conventional power banks with passive cooling.
Wireless charging has become increasingly popular in recent years, thanks in large part to Apple’s MagSafe and the broader adoption of the Qi standard. The introduction of Qi2 brought improved magnetic alignment, making it easier for consumers to achieve optimal charging positions without fuss. However, even with better alignment, heat remains a challenge. Ugreen’s MagFlow Pro is positioned as a solution for users who demand both fast convenience and long-term reliability from their accessories. By integrating liquid cooling, the company hopes to distinguish itself in a crowded market where many 10,000mAh power banks sell for less than half the price.
Design and connectivity
Beyond the innovative cooling system, the MagFlow Pro offers a practical set of features for everyday use. The power bank includes a built-in USB-C cable that doubles as a lanyard, allowing it to be slung from a wrist or a bag while still functioning as a charging cord. This integrated cable supports up to 45W of power delivery, which means it can quickly top up not just a phone but also a tablet or pair of earbuds. There is also a separate USB-C port on the device, so two additional wired devices can be charged simultaneously alongside the wireless charging coil. In total, the MagFlow Pro can juice up as many as three devices at once: one wirelessly on the magnetic pad, one through the lanyard cable, and one through the USB-C port.
It is important to note, however, that the total maximum output of the MagFlow Pro is 45W. This figure represents the combined power delivered across all output channels. If a user attaches a laptop or other high-power device through the USB-C port and simultaneously charges a phone wirelessly, the available power will be split, and charging speeds will likely decrease. Ugreen’s product page does not specify a precise distribution, but the 45W ceiling means this is not a high-capacity powerhouse for laptops. It is best suited for phones, earbuds, smartwatches, and other relatively low-draw gadgets.
The liquid-cooling phenomenon in consumer electronics
Liquid cooling is not entirely new to consumer electronics. Gaming smartphones, such as some models from Asus and Xiaomi, have used vapor chambers or liquid-filled heat pipes. High-end gaming laptops often rely on liquid metal or custom water-cooling loops. But integrating a fully circulated coolant system with a visible pump into a compact power bank is a fresh and somewhat audacious move. The MagFlow Pro’s micro-pump must be quiet, efficient, and durable enough to survive years of daily use, and Ugreen says CryoPulse technology is designed with those concerns in mind. The transparent Cyber Window allows users to verify that the pump is functioning, which could also help in diagnosing potential failures down the road.
From an engineering perspective, the challenge lies in miniaturization. A power bank’s internal volume is precious, and the addition of coolant channels, a pump, and a sealed loop means less room for battery cells. Ugreen has chosen a 10,000mAh capacity, which is fairly standard for a portable magnetic charger but may feel limiting for a device at this price point. Competing power banks with the same capacity often retail for $30 to $50, so the MagFlow Pro carries a significant premium. Ugreen is betting that the liquid-cooling technology, the dual USB-C charging options, and the integrated cable will justify the cost for users who value performance and build quality over raw capacity.
A look at Ugreen’s broader product lineup
Ugreen has been expanding its portfolio of charging accessories over the past few years, producing everything from network switches and HDMI switches to GaN desktop chargers and power strips. The company has gained a reputation for offering a wide range of cables and charging devices at competitive prices. The MagFlow Pro represents a step upmarket, not just in terms of price but also in terms of design ambition. By introducing a product with an active cooling system and a window to show it off, Ugreen is positioning itself as an innovator rather than just a maker of cheap accessories.
This launch comes during IFA 2026, one of the world’s largest consumer electronics trade shows. IFA has historically been a venue for announcing ambitious hardware, and Ugreen’s decision to debut the MagFlow Pro there is a clear statement of intent. The event is taking place in Berlin, drawing journalists, retailers, and tech enthusiasts from around the globe. While official press coverage may vary, the timing of the announcement suggests that Ugreen is eager to capture attention at a moment when the industry is focused on cutting-edge gadgetry.
How it compares to other high-end power banks
There is no shortage of premium power banks on the market. Brands like Anker, baseus, and mophie all offer magnetic wireless charging batteries with various levels of sophistication. Some include displays showing battery percentage, while others feature foldable stands or built-in AC outlets. What sets the MagFlow Pro apart is its active liquid-cooling system. While many devices use heat sinks or passive graphite films, the incorporation of a pump and coolant circuit is uncommon in this category. If the magnetic wireless charging pad maintains 25W output without overheating, it could outperform rivals that typically drop to slower charging speeds after a few minutes of operation.
Another differentiator is the integrated USB-C cable that also functions as a lanyard. This design conveniently eliminates the need to carry a separate cable when traveling, a small but welcome feature for anyone who frequently forgets wires at home. The extra USB-C port adds further flexibility, making the MagFlow Pro a versatile travel companion. However, the overall capacity of 10,000mAh means it offers roughly two full charges for a standard smartphone. That is enough for a day out but might not suffice for multi-day trips without a wall outlet.
The potential downsides of liquid cooling
While the liquid-cooling system is intriguing, it also raises questions about reliability and maintenance. A sealed cooling loop in a consumer gadget has no user-serviceable parts, and if the pump fails, the system may not be repairable. Ugreen has not provided information about the pump’s expected lifespan, but the company is likely aware of this concern and may have tested the device thoroughly. There is also the risk that adding more mechanical components could make the power bank heavier or more fragile than simpler alternatives. The visible window is a small opening in the chassis, which might make the device more susceptible to cracking if dropped. Consumers who prioritize ruggedness may prefer a more traditional power bank without such delicate elements.
Heat management has a direct effect on the health of a phone’s battery as well. High temperatures during wireless charging can accelerate battery degradation, leading to reduced runtime over time. If the MagFlow Pro’s cooling system successfully lowers temperatures at the point of contact, it could prolong the lifespan of the phone’s internal cell. This is a particularly valuable feature for users who plan to keep their phones for several years and want to avoid premature battery replacement. Ugreen claims that the combination of liquid cooling, copper foil, and separated components works to minimize heat buildup across the entire power path, not just at the charging surface.
What’s in the box and how to use it
As with most modern power banks, the MagFlow Pro will likely come with a short USB-C cable in the package, although the integrated lanyard cable means users may not need an extra cable at all. The device is designed to be attached to the back of a phone using magnets, provided the phone supports magnetic wireless charging natively or has a MagSafe-compatible case. Android users with non-magnetic phones can attach a magnetic ring or use a compatible case to take advantage of the features. The USB-C lanyard cable is detachable, so it can be used as a regular cable, and the additional USB-C port allows for pass-through charging so that both the power bank and connected devices can be topped up simultaneously when the power bank itself is plugged into an AC adapter.
Ugreen has announced that the MagFlow Pro starts shipping today for $149.99. That price puts it in aspirational territory, particularly when compared to other 10,000mAh magnetic power banks that commonly sell for about $60. However, for a user who wants the latest in charging technology, enjoys a distinctive aesthetic, and plans to keep this power bank for years, the premium might be acceptable. With IFA 2026 in full swing, it is likely that more details and hands-on impressions will surface soon. For now, the MagFlow Pro remains one of the most visually fascinating power banks to emerge this year, offering a rare glimpse inside the often hidden engineering of our everyday devices.
