UGREEN puts a liquid cooling pump inside a power bank

Wireless charging has a heat problem, and it has quietly got worse. Qi2 25W delivers nearly 70% more power than the old 15W standard, and all that extra energy has to go somewhere — which in practice means throttled speeds, a warm phone and, over time, a battery that holds less charge. UGREEN’s answer, launched at IFA 2026, is to put an actual liquid cooling pump inside a power bank. Details are on UGREEN’s site. A micro-pump in a power bank The MagFlow Pro Magnetic Power Bank is the headline, and UGREEN claims it as the first 10,000mAh Qi2 25W magnetic power bank with active micro-pump liquid cooling. Its CryoPulse system combines a micro-pump circulating coolant directly at the heat source with VC copper heat-spreading foil and a separated internal layout. UGREEN’s own testing recorded peak temperatures up to 10°C below a 48°C industry reference. There is a transparent window...
