Why are there sparks when plugging in the power cord of the Xiaomi Multifunctional Rice Cooker 1.5L?

Electrical devices can produce a surge current at the moment of being powered on, which causes slight sparking between the socket and plug. This is a normal phenomenon and usually does not indicate a problem with the device.
However, there are a few additional considerations to be aware of:
1. If the conductive copper pieces within the socket are deformed, loose, or worn out, the sparking will be more noticeable. Regularly inspect your sockets for signs of wear and replace them if necessary;
2. Ensure that the plug of the rice cooker is in good condition, with no visible damage or corrosion. A damaged plug can also increase the likelihood of sparking;
3. It is recommended to use a high-quality socket, preferably one with a switch. A socket with a switch can allow you to turn off the power before plugging in the device, reducing the chance of sparking;
4. If using a power strip, ensure it is of good quality and not overloaded with too many devices. Overloaded power strips can cause electrical issues, including sparking;
5. Make sure the area around the socket and plug is dry and free from dust or debris, as these can also contribute to sparking.
For safety, always plug and unplug devices with dry hands and avoid yanking the cord, which can damage both the plug and socket over time.
