The unnamed passenger said he had to skip breakfast in order to catch the early train, so he was hungry and decided to make a meal onboard, the Beijing Times reported, citing the Shanghai railway police.
The police posted on Weibo a photo showing a man with his rice cooker plugged into a power socket.
These sockets in trains are designed for charging low-power electronic devices such as phones, tablets or laptop computers. The power supply in the sockets is limited to 100W, while a rice cooker can draw 500W, the South China Morning post writes.
The passenger was asked to unplug the rice cooker. The Shanghai railway police reminded passengers not to use high-power electrical appliances on trains.
