A power bank is a portable device designed to recharge electronic gadgets like smartphones, tablets, and laptops when you're on the move, or when you don't have access to a regular power source. Power banks vary in size, capacity (measured in mAh), and the types of devices they can charge, offering flexibility for users with different power needs.

• Most airlines allow power banks in carry-on luggage but may restrict their size and capacity.

• Check the airline's guidelines before traveling to ensure compliance with safety regulations.
