Shanghai rail police remind customers of outlet limits after passenger cooks porridge in a rice cooker

Shanghai railway police have reminded passengers not to use high-power electrical appliances on high-speed trains after a man was found cooking porridge in a rice cooker he took on board.

The passenger said he was hungry after skipping breakfast to catch the early train, the Beijing Times reported, citing a microblog post by the Shanghai railway police.

A photo posted by the railway police on Weibo showed the man had plugged his rice cooker into a power socket at the bottom of the seat in front of him.

Such sockets are designed for charging low-power electronic devices such as phones, tablets or laptop computers.

The passenger was asked to unplug the rice cooker by a railway police officer who was patrolling the carriages, the report said.

The power supply in carriages on high-speed trains is limited to 100W, while a rice cooker can have a wattage of 500W.
