You can watch the coolant flow inside Ugreen’s liquid-cooled power bank
What's happening
Ugreen has launched the MagFlow Pro Magnetic Power Bank, a liquid-cooled portable charger featuring a transparent window that lets users watch coolant circulate through the device. The premium accessory is priced at $149.99 and available starting today.
Who's involved
Ugreen is a Chinese consumer electronics brand based in Shenzhen that specializes in USB hardware, wireless chargers, and mobile accessories. Founded in 2012 by Zhang Qingsen, the company has expanded into various consumer tech categories and is now venturing into high-end power bank design.
Why it matters
The move signals how manufacturers are blending aesthetic appeal with functional cooling technology in portable electronics, targeting consumers willing to pay premium prices for visually distinctive products. As power banks become more powerful and compact, thermal management becomes increasingly important, and Ugreen's approach demonstrates one way brands can address both performance and consumer desire for premium design.
The story
Ugreen has entered the premium power bank market with an unconventional approach: making the cooling system itself part of the appeal. The company's new MagFlow Pro Magnetic Power Bank, available today for $149.99, features what Ugreen calls "CryoPulse technology" and a "Cyber Window" that allows users to see the coolant actively flowing through the device during use. The transparent design transforms a typically hidden internal component into a visual feature.
The MagFlow Pro represents Ugreen's push into more sophisticated product categories. The Shenzhen-based company, established in 2012 by Zhang Qingsen, has built its reputation on USB hardware like cables and adapters, but has gradually expanded into wireless chargers, audio equipment, and other mobile accessories. This liquid-cooled power bank signals ambitions to compete at the higher end of the portable charging market, where aesthetics and premium features command higher prices.
Liquid cooling in consumer electronics is not entirely new, but its integration into portable power banks remains relatively uncommon. The technology is designed to manage heat more effectively than traditional air cooling, particularly important as power banks deliver higher wattages to charge multiple devices or larger batteries simultaneously. By making the cooling visible through a transparent window, Ugreen transforms what is functionally a heat-management solution into a product differentiator that appeals to consumers interested in the technical specs and visual design of their gadgets.
According to The Verge, the $149.99 price point positions the MagFlow Pro in the premium accessory category, where buyers expect distinctive design elements alongside core functionality. This pricing strategy reflects a broader shift in the portable charger market, where consumers increasingly view power banks as lifestyle products rather than purely utilitarian devices. Magnetic attachment compatibility suggests the device is optimized for iPhone integration, aligning with the current trend of magnetic accessories in the Apple ecosystem.
The launch underscores how thermal management and visual design are converging in consumer electronics. As batteries become denser and charging speeds increase, managing heat without compromising portability becomes a central engineering challenge. Ugreen's decision to showcase rather than conceal this solution suggests confidence that consumers value both the performance benefits and the distinctive appearance such technology provides.
