A fan inside a power bank sounds like overkill. The Sharge ICEMAG 3 is a 10,000mAh magnetic power bank that holds Qi2.2's 25W wireless rate by actively cooling the coil, with a 35W USB-C cable built into the side and a transparent shell that shows the work.
The cell is a 5,000mAh dual pack at 7.82V, 39.1Wh, inside a flame-retardant polycarbonate body at 220 grams. A foldable kickstand props the phone for StandBy, the built-in cable doubles as a lanyard, and the RGB ring around the fan does nothing but look the part. Black, White, and a two-tone Black + White cover the colorways.
Macworld's Simon Jary clocked a drained iPhone 16 Pro to 50% in just over 30 minutes on the 25W coil, where 15W banks take around 45, and his recharge test scored 171%: one full phone charge plus most of a second. Heat is what usually throttles those numbers flat.
Qi2.2's 25W is the headline; the fan is what keeps it honest.
The fan is also the argument. Jary called the ICEMAG 3 the noisiest power bank he's tested, with a hum that's "quite noticeable" in a quiet room; 9to5Mac's Fernando Silva ran the same hardware and could barely hear it. Where you charge decides which reviewer you'll agree with. Silva's one wish was a battery display, the single number the see-through shell doesn't show.
The built-in cable mostly serves iPhoners on USB-C models, the 15 line onward, per Jary's note on its fit. On the wireless side it spans Qi at 5W through 15W for everything else, and the magnets grip from the iPhone 12 up. Silva's bottom line lands where the hardware does: the cooling is the feature, and "it is not a gimmick."
