What items are prohibited from being moved from the cabin to the hold?

Powerbanks are prohibited from being moved from the cabin to the hold due to safety regulations concerning lithium-ion batteries. These batteries, which power most electronic devices including powerbanks, have the potential to overheat and cause fires if they are damaged or improperly handled. When powerbanks are kept in the cabin, cabin crew can monitor them more effectively, reducing the risk of incidents during the flight. It's important to ensure items that pose such risks are retained in the cabin where they can be accessed and managed by crew members in the event of an emergency.
