Do K-series trains have charging facilities?

[MacBrynlee]

K-series trains have charging sockets located in the corridors of sleeper carriages. Passengers who purchase sleeper tickets can use these sockets to charge their mobile phones. However, for passengers with hard-seat tickets on K-series trains, there are no charging sockets available in the carriage. If hard-seat passengers run out of battery, they can seek assistance from the train attendants. The attendants may take the passenger's phone to the staff restroom for charging. Since there is only one charging socket per hard-seat carriage, resources are very limited. Therefore, the train attendants may charge a fee based on the duration of charging. Charging on K-series trains can be quite challenging, so it is recommended that passengers fully charge their phones before departure and conserve battery during the journey by minimizing phone usage. If possible, bringing a power bank can provide additional peace of mind during the trip.
