The ordinary phone charger you are holding tightly in your hand may seem ordinary, but it hides a stunning scientific mystery - fast charging technology. When you gently press the power button, a strong current quickly rushes towards your phone, and within a few minutes, it can be fully revived. So, what scientific principles are hidden behind this? Let's unveil the mystery of fast charging technology together.

In traditional mobile phone charger manufacturing, plastic and metal are the main raw materials. Although these materials have good durability and conductivity, they are difficult to degrade and long-term retention in the environment can cause serious damage to the ecosystem. In addition, traditional chargers consume a large amount of energy during the production process and generate a large amount of exhaust gas, wastewater, and solid waste, exacerbating global climate change and environmental degradation.

Today, I will lead you to explore the working principle of mobile phone chargers and how modern technology makes charging more efficient and safe.

Firstly, let's unveil the mysterious veil of mobile phone chargers. A mobile phone charger mainly consists of a power adapter, cable, and charging interface. The power adapter is responsible for converting AC power to DC power, the cable transmits electrical energy to the phone, and the charging interface is the bridge connecting the phone and the charger.
