Surprised by how much electricity is consumed each year without unplugging the mobile phone charger

I believe that many people have the habit of plugging in the mobile phone charger and not pulling it out. It is very convenient to charge and use it at any time. But have you ever thought about the power consumed in vain behind this?

Foreign media ZDNet website technology author Adrian Kingsley-Hughes explored this. There are 6 chargers for smartphones and tablet computers in his home, all of which are connected to the power supply and do not charge the mobile phone. How much electricity will they waste?

Adrian tested the charger with a WattsUp PRO power meter, and the results showed that an original Apple iPhone charger consumes 130 watts per month, or about 1.5 kWh per year.

According to the electricity fee of 0.18 US dollars (about 1.22 yuan) for 1 kWh, the annual electricity fee is only 0.27 US dollars. Even if there are 6 chargers, the annual electricity consumption is only a few dollars, not more than 2 dollars.

To most people, that number might seem like $2 a year for plugging and unplugging chargers without much trouble. In China, the electricity bill is cheaper, so it is 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 chargers is much higher than that of the original ones, and the addition of millions of chargers around the world consumes a considerable amount of power.

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. Also, unplugging the charger is good practice and can greatly reduce the risk of a fire.
