The phone runs out of battery cannot fly
According to US Secretary of Homeland Security, Jeh Johnson , these are measures to increase security at airports abroad when making direct flights to the United States. All electronic devices are inspected by security personnel. During the inspection period, employees may also request owners to turn on some devices, including mobile phones. Devices that do not work will not be allowed on the aircraft.
Redundant charger is about to sell
The reason for this new rule is that TSA is worried about " a mobile phone, tablet, or other electronic device " that can be used to hide an explosive device. For those who do not have the habit of charging the device when they are nearly out of battery, they will probably have to buy a spare charger immediately if they do not want to stay at the airport.
