I believe that many people have the habit of plugging the mobile phone charger into the plug and unplug, which is very convenient. But have you thought about wasting electricity?
ZDNet website technology author Adrian Kingsley-Hughes explored this. He has 6 smartphones and tablet chargers in his home. All of them are connected to the power supply and do not charge the mobile phone. How much electricity will they waste?
Adrian used the WattsUp PRO power meter to test the phone charger. The results showed that an original Apple iPhone charger was unplugged and consumed 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 bill is only 0.27 US dollars. Even with six 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 necessary.
But Adrian believes that it is still necessary to unplug the charger when not in use. First of all, the power consumption of non-original mobile phone chargers is much higher than that of original mobile phone chargers, and millions of chargers around the world are accumulating, and the power consumption is very large. From an environmental point of view, every kilowatt-hour of electricity generated 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.
