The accessory aisle at IFA 2026 is packed with chargers and power banks, but Ugreen is hoping its newest magnetic power bank rises above the noise by solving a problem many wireless charging users know all too well: heat. The new MagFlow Pro Magnetic Power Bank has an actual liquid-cooling system inside, complete with a transparent window that lets you watch the coolant circulate while your phone tops up.
Ugreen calls its cooling approach CryoPulse Technology. The company claims this is the world’s first liquid-cooling system integrated into a power bank that also supports wireless charging. A micro-pump inside the device pushes coolant through a small loop, drawing heat away from sensitive components. The cooling path passes through the area around the Qi2.2-compatible wireless charging coil, which is the part of the power bank most likely to get warm when transferring energy to a phone. A cleverly placed transparent “Cyber Window” on the front panel allows you to see the coolant flowing in real time. The moving liquid is a neat visual effect, but Ugreen says the real benefit is thermal management.
The coolant system works alongside a copper foil layer and a board layout that keeps charging components physically separated. These measures are meant to reduce hot spots, lower overall operating temperatures, and maintain steady charging speeds. According to the company, that design helps extend the life of both the power bank itself and the handset placed on its charging surface. The result should be a power bank that remains cooler to the touch after a long charging session, rather than becoming uncomfortably warm.
Why heat is such a problem in wireless charging
Wireless charging relies on an electromagnetic field to transfer power between two coils. The process is less efficient than a direct wired connection, and the wasted energy often turns into heat. This is especially true when a power bank is tightly packed and has less room for airflow. Heat can cause lithium-ion batteries to degrade faster, can force chargers to reduce their output to protect circuitry, and can make a device uncomfortable to hold after a long charging session.
Most power banks try to combat heat with passive methods: thermal pads, ventilated enclosures, or temperature sensors that lower charging speed when things get too warm. Ugreen’s MagFlow Pro takes a more active approach with its liquid pump. Liquid cooling has been used in gaming laptops, desktop PCs, electric vehicles, and some smartphones, particularly gaming phones. It remains rare in power banks and portable charging accessories. That makes the MagFlow Pro a bit of an outlier and a talking point for people who push their devices hard.
MagFlow Pro specs and charging capabilities
Beyond the cooling system, the MagFlow Pro is a 10,000mAh magnetic wireless charger that also supports Qi2.2. It can charge phones wirelessly at up to 25W, which should be enough for compatible Android flagships and recent iPhones that support faster Qi2 charging. The power bank includes a lanyard that doubles as a built-in USB-C charging cable. There is also a separate USB-C port on the unit. This means you can charge up to three devices at the same time: one wirelessly on the magnetic pad, one through the lanyard cable, and one through the additional USB-C port.
Both wired connections can deliver up to 45W, but that is also the maximum total output of the MagFlow Pro. If you use two wired outputs simultaneously, or pair any wired output with wireless charging, the power bank will split the available power across the devices, gradually reducing their charging rates. This is an important consideration if you plan to charge a laptop and a phone at the same time. In that case, a 45W-capable laptop may not run at full speed while the phone is also drawing power.
The 10,000mAh capacity is enough for around one full charge for most modern smartphones, or about two partial charges for smaller phones. It is not designed to be an all-day travel battery for tablets or laptops. Instead, its slim profile and magnetic attachment make it convenient for everyday use, especially during travel or at events where you need a fast boost without dealing with messy cables.
Price and availability at IFA 2026
The Ugreen MagFlow Pro is available starting today for $149.99. That is a high price for a 10,000mAh power bank, even one with wireless charging. Many comparable products from Anker, Baseus, and other brands can be found for $30 to $60. The added cost is tied to the liquid-cooling system, the Cyber Window, the built-in cable lanyard, and the Qi2.2 support.
The product is being shown at IFA 2026 in Berlin as part of Ugreen’s broader release lineup. The company has expanded well beyond simple cables and chargers in recent years, selling docking stations, monitor arms, surge protectors, and a growing range of gaming accessories. Bringing liquid cooling to a power bank highlights Ugreen’s willingness to use high-end thermal engineering in everyday gadgets.
For anyone who spends a lot of time charging their phone on a nightly basis or doing daily wireless top-ups in a warm car, the MagFlow Pro’s active cooling could be genuinely useful. It may also provide peace of mind for users who are concerned about battery health and want to keep their phone as cool as possible during charging. For others, the price may be hard to justify when a standard 10,000mAh power bank costs a fraction as much.
The clear Cyber Window is more than just a gimmick. It gives users immediate visual feedback that the cooling system is running and helps build trust in a feature that would otherwise be invisible. As the coolant begins to move the moment you start charging, you can see that the MagFlow Pro is actively managing heat, not just passively spreading it around.
For now, the Ugreen MagFlow Pro occupies a niche position. It combines an unusual cooling mechanism with a relatively modest battery capacity and a premium price. Whether it becomes a trendsetter or a novelty will depend on how much the average user values a cool, visible, liquid-cooled charging experience.
