Ugreen MagFlow Air 10000mAh: our review
10,000 mAh in a 0.55 in (13.9 mm) body weighing 7.5 oz (213 g), with a built-in USB-C cable that doubles as a lanyard: the MagFlow Air delivers about 34 Wh from 39.2 Wh nominal and posts one of the best wireless recharge scores in its class. Its thinness is paid for in heat, and its total output drops to 15W as soon as a second device is plugged in.
