Some people are used to plugging the quality type c wall charger into the socket all the time, so that they can be used anytime, but have you ever wondered whether the quality type c wall charger will consume power if it is always plugged into the socket?
First of all, we need to know that the transformer has the function of changing voltage. Transforming voltage is to convert high voltage into low voltage first, and then output it to electrical appliances, that is, your mobile phone. The voltage transformation principle of the quality type c wall charger is electromagnetic induction. There is a coil in the transformer that is connected to the power supply. When the current passes through, a magnetic field is generated to generate alternating current at different voltages, which is then converted into direct current through a rectification circuit and other processes. phone charging.

Generally speaking, a quality type c wall charger that has not been unplugged from the socket and is not connected to an electrical appliance is in a "no-load" state. power consumption. Therefore, as long as it is not unplugged, there will be a coil that is always working, thus consuming power.
Kind tips:
When purchasing a quality type c wall charger, you must choose qualified products from regular manufacturers, and do not buy products from small factories with unqualified electrical performance. A quality type c wall charger has an internal overheating self-protection circuit. When its internal temperature reaches a certain value, it will automatically cut off the power supply to play a certain degree of protection.
