Across global airports, a little-known but crucial requirement is enforced: your electronic device must be able to power on when requested by security staff. If your phone or tablet is dead and cannot demonstrate normal operation, it may be confiscated as a safety precaution.
This rule applies to smartphones, tablets, laptops, e-readers and most portable electronics. In some airports, officers may even ask travelers to turn on devices at the entrance to the terminal.
European airlines remind passengers of this rule:
- British Airways states that security officers can require any device to be powered on before boarding.
- TUI recommends keeping gadgets charged until boarding, as spot checks may occur unexpectedly.
The reason is simple: an imitation explosive cannot function as an electronic device, so powering it on is a quick security verification.
