The reason why the Wanzhuo egg waffle machine consumes power in standby mode is because it still needs power supply in standby mode to maintain some basic functions, such as maintaining the brightness of the display and keeping the internal circuits running, etc. The maintenance of these functions requires a certain amount of power support, so even if the machine is in standby mode, there will still be a small amount of power consumption.

In addition, the standby mode in modern electronic devices usually also includes some standby functions, such as quick start during standby, receiving signals from remote controls, etc. These functions also require a certain amount of energy support, thus resulting in power consumption in standby mode.

In terms of expansion, standby power consumption does not only exist in egg waffle machines, but almost all electronic devices consume power in standby mode. In order to reduce standby power consumption, you can take some measures, such as turning off the power in time when the device is not in use, using power sockets with energy-saving functions, setting the automatic sleep function, etc. These measures can effectively reduce standby power consumption and save energy.
