Power adapter industry is one of the few evergreen industries in our country, which provides a lot of convenience for the public in all aspects of life, production and marketing has been kept in the upper circle. By 2018, China's output value of power adapter reached 198.014 billion yuan, up 7.73% year-on-year. The following is an analysis of the adapter industry. In recent years, with the sustained and high-speed development of China's macro-economy, the power supply adapter industry in general has been maintaining a steady growth, even after the baptism of the global financial crisis, the output value of the power adapter industry in China still exceeded 100 billion yuan in 2009. Adapter market analysis, in 2012, with the recovery of the global economy, the output value of China's power adapter industry accelerated to 130.4 billion yuan, year-on-year growth rate of 11.26% , showing a good development trend; In 2017, the output value of the power adapter industry reached 181.997 billion yuan, up 7.54 percent year on year, and reached 198.014 billion yuan in 2018. In terms of sales, 197.882 billion yuan of power adapter industry sales in 2017, up 6.24 percent year-on-year; to 217.533 billion yuan of sales in 2018. According to the analysis of adapter industry, there are many kinds of power adapter products in our country, and the standard and quality management of the products are scattered. From the point of view of electrical performance parameters, the charging effect of different power adapters is completely different. If you choose the wrong power adapter to charge it may also cause damage to phones, tablets. Thus, the use of power adapter is more extensive. Power adapters are widely used not only in mobile phone charging, but also in many industries.

First, with the implementation of the national energy-saving and emission-reduction policies, Led-type energy-saving lamps have been accepted by the majority of consumers, its brightness and energy-saving effect is allowed. In this case, the use of power supply adaptation will be further increased. The national population of more than one billion, its lighting use is a huge number, the use of power adapter is also very large. Second, electronic products have filled our lives, in daily life, mobile phones, tablets, laptops are gradually increasing the use of, this time the use of power adapter is also increasing. Adapter industry analysis, it can be said that the market development of digital products led to the development of the power adapter industry. At present, power adapters are widely used in the consumer electronics industry, providing most of the output power within 100 watts, and the market demand is growing rapidly. Such as electric bicycle battery chargers, small LCD tvs, laptops, printers, DVD players and set-top boxes are used. Early power adapters mostly used linear transformers. With consumer electronics demanding high efficiency and a wide input voltage range for power adapters, as well as increasing costs of copper, iron and manpower, in this kind of power adapter, the original linear transformer is gradually replaced by switching power supply. As a whole, the market of power adapters in China will certainly expand with the continuous expansion of the electronic product market in the next few years, and high-quality power adapters will become the first choice of consumers, after all, power adapter is not a one-time consumer products, only to ensure the quality will be recognized by consumers.
