Ugreen’s new MagFlow Pro series integrates liquid cooling and TEC technology to address heat-induced speed limits in wireless charging devices, offering significant advances in portable power and multi-device charging efficiency.
UGREEN has introduced a new MagFlow Pro charging range that places thermal management at the centre of its design, as the company seeks to address one of the main constraints on faster wireless charging: heat. The three-device line-up comprises a 10,000mAh magnetic power bank, a 3-in-1 stand charger and a foldable 2-in-1 charger. According to UGREEN Japan, the products are now on sale through the company’s own online store, Amazon and Rakuten, as well as major electronics retailers including Bic Camera and Yodobashi Camera.
The new range is built around UGREEN’s CryoPulse cooling approach, which combines liquid cooling with TEC-based temperature control and additional heat-dissipation design. The company says the aim is to move heat away from the charging components more quickly, helping to reduce the kind of thermal build-up that can slow charging speeds and make a handset uncomfortable to hold during use. That focus on cooling mirrors a wider trend in high-output wireless charging, where power delivery is increasingly limited by temperature rather than by raw wattage alone.
The flagship MagFlow Pro 10,000mAh magnetic power bank is, according to UGREEN, the first Qi2 25W portable battery pack to use an integrated liquid-cooling system. Gizmochina reported earlier this month that the device also uses phase-change thermal storage material and a micro-pump to circulate coolant, with a transparent section that lets users see part of the system in operation. UGREEN’s own testing, carried out at an ambient temperature of 25C with an iPhone 17 Pro Max, indicates that the unit runs around 10C cooler than a conventional power bank under similar charging conditions. The company also says the pack can charge an iPhone 17 Pro Max to 50 per cent in about 40 minutes and includes a smart display showing cooling status, output, battery level and charge-cycle data.
The 3-in-1 stand charger is aimed at users charging an iPhone, Apple Watch and AirPods at the same time. UGREEN says it pairs CryoPulse TEC cooling with an ultra-quiet fan and can take an iPhone 17 Pro Max to 50 per cent in roughly 26 minutes. The company’s test results suggest the TEC module can bring the centre of the charging surface down to about 11C. The stand is also adjustable, making it easier to keep the display visible while watching video or checking alerts. The foldable 2-in-1 charger is designed for portability, supporting up to 25W for an iPhone and up to 5W for an Apple Watch or AirPods, while doubling as a stand when opened. When folded, it is small enough to fit in a bag or pouch, positioning it as a travel-friendly option for offices, hotels and trips.
