Will your phone charger consume if you don't unplug it? How much electricity does it consume per year?2020-12-21
It is believed that many people have the habit of plugging in the mobile phone charger. It is very convenient to use it at any time. But have you ever thought about the amount of electricity wasted behind it? Foreign media ZDNet technology author Adrian Kingsley-Hughes explores this. He has six chargers for his smartphones and tablets at home, all plugged into the mains and not charging the phone. How much electricity are they wasting by themselves?
Adrian USES WattsUp PRO power meter on the charger was tested, the result shows that an original apple iPhone charger not pull, consumption of electricity is 130 watts per month, each year about 1. 5 KWH.
At $0.18 for a kilowatt-hour of electricity, that's $0.27 a year. Even with six chargers, the electricity bill is only a few dollars a year, or less than $2.
To most people, that figure might seem like $2 a year without bothering to plug and unplug the charger. In China, where electricity is cheaper, it is even less necessary.
But Adrian says it's still necessary to unplug the charger when not in use.
First of all, non-original chargers consume a lot more power than original chargers, and when added up around the world, millions of chargers are limited to plug and unplug, which is a significant amount of power.
Environmentally speaking, for every kilowatt-hour of electricity generated, one pound of carbon dioxide is emitted into the atmosphere.
In addition, unplugging the charger is a good habit and can greatly reduce the risk of fire.
