Bringing batteries onto an airplane

The battery for the "Air Conditioned Jacket" is treated the same as a mobile battery.
Therefore, it must be carried on board, and it cannot be placed in checked baggage in the cargo hold. You need to bring it into the airplane and keep it with you, rather than storing it in the overhead compartment above your seat.

Many airlines use the watt-hour rating (Wh) as the standard, so when taking them home, it is necessary to pay attention to whether they can be carried on board and if there are limits on the number of items.
The number of items you can bring varies depending on the airline, so it is recommended to check the airline's regulations in advance. Airline regulations may change over time, so please confirm them before making a purchase.
In addition, land and sea routes are not subject to this, so we kindly ask you to check the respective regulations.
