New regulations taking effect July 1st will limit passengers to carrying a maximum of two portable chargers (power banks) on aircraft. These chargers must be kept within carry-on luggage, not checked baggage. The aviation authority implemented these rules to enhance flight safety. The change applies to both domestic and international flights departing from Vietnam. Passengers exceeding the limit may face confiscation of the excess items. Authorities have not specified penalties beyond confiscation at this time. The new rule aims to mitigate potential risks associated with lithium batteries found in portable chargers.
