Why are there special rules for bringing power banks on airplanes?

With the widespread use of smartphones and tablets, mobile batteries have become an essential item for travel and business trips. However, there are special rules for carrying mobile batteries on airplanes. This is because lithium-ion batteries pose a risk of fire due to overheating or short circuits. In the past, there have been reports of fires on board, so airlines and international organizations have established clear rules for safety. It is important to understand these rules to ensure a safe air travel experience.

2025 Airline Regulations: Carrying on Power Banks

As of 2025, most airlines only allow mobile batteries as carry-on baggage; they cannot be placed in checked baggage. There are also restrictions on capacity, with batteries under 100Wh generally being accepted without issue. Batteries over 100Wh require airline approval.

Additionally, there is a limit on the total amount of batteries you can bring with you. As a safety measure, it is recommended that you cover the battery terminals with tape. By following these rules, you can prevent any problems during your trip.
