I believe that many people have the habit of plugging the phone charger into the plug and unplugging it, which is very convenient. But have you thought about wasting electricity?
ZDNet website technology author Adrian Kingsley-Hughes explored this. There are 6 smartphones and tablet chargers in his home. All of these are connected to the power source and do not charge the phone. How much power will they waste?
Adrian uses the WattsUp PRO power meter to test the phone charger. The results show that the original Apple iPhone charger has been unplugged, consuming 130 watts per month, about 1.5 kWh per year.
According to the electricity fee of 0.2 US dollars for 1 kWh electricity, the annual electricity fee is only 0.27 US dollars. Even with eight chargers, the annual electricity bill is only a few dollars and will not exceed $2.
For most people, this number does not seem to require a charger, no more than $2 a year. In China, electricity is cheaper and even less.
But Adrian believes that the charger still needs to be unplugged when not in use. First, the power consumption of non-original mobile phone chargers far exceeds that of original mobile phone chargers. Millions of chargers around the world are accumulating and consume a lot of power. From an environmental point of view, every kilowatt hour of electricity will emit 1 pound (about 0.45 kilograms) of carbon dioxide into the atmosphere. In addition, it is a good habit to unplug the charger.
