In modern life, we are surrounded by various rechargeable equipment. For example, there may be a mobile phone or a charging device next to the socket at home, which can be plugged in for many years. However, is there any risk in doing this? Will you silently increase your phone fee?
What's in the charger?Experts point out that not all chargers are the same length, but basically they have a common job of converting the AC on the wall into DC power that the equipment can use.
. AC: The current direction will change backwards, suitable for long-distance transmission, such as delivering it to your home from a power plant.. DC: Current continues to flow in one direction, which is a standard form of power for batteries and electronic products.
Therefore, this is why there are conversion circuits inside the charger, including transformers, rectifiers, filters and control circuits. The plugged charger is actually power-consuming. Experts point out that even if the mobile phone is not charged, as long as the charger is plugged in, it will continue to consume power. This phenomenon is called standby power consumption.
Although each charger consumes very little power, if you have a lot of equipment at home, the total amount of power will be very impressive if you add up to one year. For example, TV, audio, microwave, etc., it will continue to consume a small amount of electricity as long as it is inserted.
However, the current charger design is increasingly power-saving, and some will automatically enter sleep mode without connecting to the device, almost without power consumption.
Other potential risks: Security issues cannot be ignoredIn addition to the cost of the computer, safety is also a key consideration. For example, the voltage is often seen on the Internet, plugging in the charger over a long period of time may cause the components to gradually age.
Although this happens in all electronic products, it is not a high risk for modern qualified chargers, if it is convenient, occasionally unplugging is also a way to prolong life.
In addition, cheap or uncertified chargers may not have over voltage, heat and other protection designs, and may even have fire risks.
Even though most of the current chargers are safe and stable, if the charger on your hand has the following conditions, you should change:
. Anomalous irritation. There are strange sounds (like buzzing sound)
. Cracked shell or foot insertion deformed
