Japan bans the use of power banks on flights starting in April.

According to a report from Japan's Kyodo News on the 18th, due to multiple incidents of mobile power banks catching fire on airplanes, the Japanese Ministry of Land, Infrastructure, Transport, and Tourism has notified all airlines that the use of power banks on board will be completely prohibited starting in April. The new regulations clearly state that using power banks to charge devices such as mobile phones is prohibited, as well as charging power banks through onboard sockets. According to previous reports, in July last year, Japan had already required that power banks not be placed in overhead compartments, but must be charged and stored in a state that can be checked at any time, in order to further strengthen control measures. It is reported that lithium-ion batteries used in power banks are prone to catching fire or smoking due to aging and physical impact, therefore they are prohibited from being checked as baggage and there are restrictions on the number and capacity that can be carried on person. The report also mentioned that these new regulations were prompted by several incidents. In January last year, a suspected fire caused by a power bank occurred at Busan Airport in Korea, and similar safety hazards have also been observed in Japan.
