CMB departure security pulled my power bank from hand luggage — confiscation normal or did I pack wrong?

Power banks belong in hand luggage, not checked bags, and damaged or unlabeled capacity stickers raise flags. Officers may refuse banks that look swollen, unlabeled, or above what their current screening allows — I will not invent a watt-hour number as gospel because rules and enforcement vary. Next time: clear label intact, bank not hot or swollen, easy to remove from the tray, and spare time if they ask questions. Confiscation happens when the bank fails a check; it is not personal. Buy a clearly labeled bank before the next flight if yours is gone.
