What is the daily power consumption of the 12V1A power adapter to power the router?

12V1A power adapter is very common in our daily life, such as routers, phone boxes, stereos and other devices are used to charge with this adapter. So how many hours of electricity do these appliances consume in a day? How much is a year?

The electronic equipment, such as routers and set-top boxes at home, is powered on and working 24 hours a day. For the convenience of calculation, we assume that the 12V1A plug-in power adapter is fully loaded 24 hours a day, with an output voltage of 12V and an output current of 1A.

What is the daily power consumption of the 12V1A power adapter to power the router?

According to the physical electrical equation P=UI, the electricity consumed in one hour is W=PT=12*1*1H=12Wh, so the energy consumed in one day is 12W*24H=0.288 KWH. It consumes 0.288*365=105.12 KWH per year. Of course, 105.12 kilowatt-hours is less than the actual power consumption when the 12V1A power adapter is fully loaded throughout the year.

Although the power consumption of the 12V1A power adapter is small in a day, over the course of a year, it will need to consume a lot of power. If the adapter you buy is a hybrid brand, the circuit design is not reasonable, the material is poor, the current conversion efficiency is low, so that you need to consume more electricity.

Therefore, I still suggest that you choose a big brand, with good materials and high energy conversion efficiency of 12V1A power plug wall adapter.
