In response to safety concerns, Japanese airlines are heading towards banning the use of 'MoBaJu', a popular portable charger, onboard. No specific timeframe has been declared for this shift, but the change is aimed at addressing potential fire risks associated with these devices. The decision has come after a series of reported incidents involving 'MoBaJu', thus prompting a broader discussion on aviation safety standards and related tech usage.

Safety is a prominent value in Japan, particularly on subjects that impact public welfare. Given the high usage rate of 'MoBaJu' among urban commuters and travelers, this move reflects the government's resolution to put safety before convenience. The decision is receiving mixed reactions from the public, with some praising the precaution, others lamenting the loss of a convenience tool.

In the US and EU, airlines have guidelines for lithium batteries, such as 'MoBaJu'. While not outright banned, travelers are strongly advised to keep these in carry-on baggage due to safety reasons. Some airlines have gone further to ban 'smart bags' with built-in lithium batteries that can't be removed. However, a comprehensive ban on portable chargers is not common.
