The UGREEN MagFlow Pro Qi2 25W Magnetic Charger with Cooling does what it promises, but there is one detail worth knowing before you buy. The cooling fan only runs at full speed if you pair it with a 45W or higher charger, which is sold separately. With my 45W adapter the fan is clearly working and the phone stays cooler than on my old magnetic charger. Magnet alignment is solid and charging feels quick. Just budget for a stronger adapter if you want the full cooling performance.
