You can directly look at the specifications on the plug of the router, generally 12V 0.6A or 9V 0.6A and 5V 1A.

Power is equal to voltage times current. 12X0.6=7.2 9X0.6=5.4 5X1=5 The power unit is W. The usual kilowatt-hour of electricity is 1000 watt-hours.

1000 divided by the above three numbers is the time it takes to consume one degree of electricity. Take 5V 1A as an example, the power consumption is 5W. 200 hours to one degree of electricity. And it is still the maximum output of the transformer on the plug, in fact, the router has an energy-saving design and cannot work in the full power state. So the power consumption is very small.
1. Wifi on all night consumes electricity.
2. Because Wifi needs to connect to the network, it needs to consume electricity.
At the same time, the longer the Wifi is used, the more power it consumes. 3. If you want to reduce the power consumption of Wifi, you can try the following methods: turn off unnecessary network connections, reduce the brightness of Wifi, use power-saving mode, etc.
At the same time, you can also choose more energy-efficient devices to use Wifi.
